You will need to develop a system that can track employee information for two Organizations (such as Google and Microsoft). The Employee information you must track is as follows: Name Gender Job Title Organization they work for Birthday As for the Organization that the Employee works for, you must also track this information: Organization Name Number of Employees The system must be able to properly compare any two employees against each other to determine if they are the same Employee. This means that if you compared two Employees with the same Name, Gender, Birthday and Organization, the system should think that they are equal to one another. If any of these properties are different, then the two Employees are not the same Employee. The same rules apply to comparing Organizations to one another. Organizations with the same Organization name are to be thought of as equal, different names means different organizations. Use the charts on the next page to create your classes. Employee private String name; private String gender; private String jobTitle; private Organization organization; private String birthDate; Employee(String theName, String theGender, String title, Organization org, String theBirthDate) <> String getName() String getGender() String getJobTitle() Organization getOrganization() String getBirthDate() String toString() boolean equals(Employee other) <> void changeJobTitle (String newTitle) void changeName(String newName) void changeOrganization(Organization org) Organization private String organizationName; private int numEmployees; Organization(String name, int employees) <> String getOrganizationName() int getNumEmployees() String toString() boolean equals(Organization other) <> void changeOrganizationName(String newName) *****NOTE: All constructors and methods should be public. ***** *Note: There is a zip file listed that has a starts for each of the classes that are required. They are located in the source file and you will also find a test file for the program.

Repeat Programming Project 2 in Chapter 5. This time, add the following four constructor
methods: one for each instance variable, one with two parameters for the two instance variables,
and a default constructor. Be sure that each constructor sets all the instance variables. write a
driver program to test each of the methods, including each of the four constructors and at least
one true or false case for each of the test method.

wise sales totals. Your query should show Customers\' Country name and the total sale value for
that Country 2) Write a query to show Product wise sales totals. Your query should Product
name and the total sale value for that Product. 3) Write a query to show the number of orders for
each shipper. Your query should show shipper name and the count of orders with the shipper. 4)
Write a query to show number of products in each product category. Your query should show
Category name and number of products in that category 5) Write a query that shows Customers\'
country wise customer count, and order count. Your query should show country name, total
number of customers from that country, and total number of orders from the customers of that
country 6) Write a query that shows the number of products supplied by each Supplier. Your
query should show Country name, supplier name and the count of products supplied by that

The main method creates sample employees, alters values, calculates pay and bonuses, applies raises, and outputs the results.
2. Create a Java class called EmployeeMain within the same project Pr.docx
The document defines an Employee class with instance variables like employee ID, name, and basic salary. It includes getter and setter methods for the variables, and a method to calculate a 1% bonus on basic salary. An EmployeeMain class contains a main method that creates Employee objects, collects user input for name and salary, and displays employee details including ID, name, salary, and bonus.
Hi, I need help with a java programming project. specifically practi.pdf
Hi, I need help with a java programming project. specifically practice Program number 1 on page
662 from chapter 7 of the 7th edition of the book , java:an introduction to problem solving and
programming. it tells me to define a class named employee whose objects are records for
employees, it then tells me to derive the class from a class called person. it tells me that the
employee record should contain an annual salary(represented as single value of type double), a
hire date(that gives hired year as single type of int) and a social security number or ssn as a value
of type string. My professor provided us a test program to test out both classes, but I am having a
hard time figuring out how to get both classes to work within my test program.
Here is my person class
public class Person
{
public String name;
public Person()
{
name = \"No name yet.\";
}
public Person(String initialName)
{
name = initialName;
}
public void setName(String newName)

}
public void writeOutput()
{
System.out.println(\"Name: \" + name);
}
public boolean sameName(Person otherPerson)
{
return (this.name.equalsIgnoreCase(otherPerson.getName()));
}
}
Here is my Employee class
public class Employee extends Person
{
private double annualSalary;
private int hiredYear;
private String SSN;
//constructors which include parameters such as employee name, salary and hire date
public Employee (String initialName, double initialSalary, int joinedYear, String id)
{
super(initialName);
annualSalary = initialSalary;
hiredYear = joinedYear;
SSN = \"000-00-0000\";
}
//sets salary
public void setAnnualSalary( double newSalary)
{
annualSalary = newSalary;
}
//sets year hired
public void sethiredYear( int year)
{
hiredYear = year;
}
//set employee ssn
public void setSSN(String newSSN)
{
SSN = newSSN;
}
// return annual salary
public double getAnnualSalary()
{
return annualSalary;
}
//return hired year
public int getHiredYear()
{
return hiredYear;
}
//return SSN
public String getSSN()
{
return SSN;
}
//return true if both employee objects are the same. Otherwise return false
public boolean equals(Employee otherEmployee)
{
if(name.equals(otherEmployee.name))
if(annualSalary == otherEmployee.annualSalary)
if(hiredYear == otherEmployee.hiredYear)
if(SSN == otherEmployee.SSN)
return true;
return false;
}
//prints employee name, annual salary, year hired and ID
public void display()
{
System.out.println(\"Employee name: \" + name);
System.out.println(\"Employee salary: \" + annualSalary);
System.out.println(\"Employee hired year: \" + hiredYear);
System.out.println(\"employee ssn: \" + SSN);
System.out.println();
}
}

not allowed to alter this test program in anyway.

number of employee in the company and create a 2-dimensional dynamic array (number of
employee by 4 weeks). Then, the program should ask user to enter each employee’s information
and the amount of hours they worked weekly.
The program shows a menu with employee name for user to choose which employee to display
the following information:
How much the person totally made
How much of paycheck is regular pay
How much of paycheck is overtime pay

The document defines an Employee class and subclasses for Hourly, Salary, and Commission employees. It includes methods to calculate pay, apply raises, and reset tracking periods. The main method creates sample employees, alters values, calculates pay and bonuses, applies raises, and outputs the results.
2. Create a Java class called EmployeeMain within the same project Pr.docx
The document defines an Employee class with instance variables like employee ID, name, and basic salary. It includes getter and setter methods for the variables, and a method to calculate a 1% bonus on basic salary. An EmployeeMain class contains a main method that creates Employee objects, collects user input for name and salary, and displays employee details including ID, name, salary, and bonus.
Hi, I need help with a java programming project. specifically practi.pdf
Hi, I need help with a java programming project. specifically practice Program number 1 on page
662 from chapter 7 of the 7th edition of the book , java:an introduction to problem solving and
programming. it tells me to define a class named employee whose objects are records for
employees, it then tells me to derive the class from a class called person. it tells me that the
employee record should contain an annual salary(represented as single value of type double), a
hire date(that gives hired year as single type of int) and a social security number or ssn as a value
of type string. My professor provided us a test program to test out both classes, but I am having a
hard time figuring out how to get both classes to work within my test program.
Here is my person class
public class Person
{
public String name;
public Person()
{
name = \"No name yet.\";
}
public Person(String initialName)
{
name = initialName;
}
public void setName(String newName)
{
name = newName;
}
public String getName()
{
return name;
}
public void writeOutput()
{
System.out.println(\"Name: \" + name);
}
public boolean sameName(Person otherPerson)
{
return (this.name.equalsIgnoreCase(otherPerson.getName()));
}
}
Here is my Employee class
public class Employee extends Person
{
private double annualSalary;
private int hiredYear;
private String SSN;
//constructors which include parameters such as employee name, salary and hire date
public Employee (String initialName, double initialSalary, int joinedYear, String id)
{
super(initialName);
annualSalary = initialSalary;
hiredYear = joinedYear;
SSN = \"000-00-0000\";
}
//sets salary
public void setAnnualSalary( double newSalary)
{
annualSalary = newSalary;
}
//sets year hired
public void sethiredYear( int year)
{
hiredYear = year;
}
//set employee ssn
public void setSSN(String newSSN)
{
SSN = newSSN;
}
// return annual salary
public double getAnnualSalary()
{
return annualSalary;
}
//return hired year
public int getHiredYear()
{
return hiredYear;
}
//return SSN
public String getSSN()
{
return SSN;
}
//return true if both employee objects are the same. Otherwise return false
public boolean equals(Employee otherEmployee)
{
if(name.equals(otherEmployee.name))
if(annualSalary == otherEmployee.annualSalary)
if(hiredYear == otherEmployee.hiredYear)
if(SSN == otherEmployee.SSN)
return true;
return false;
}
//prints employee name, annual salary, year hired and ID
public void display()
{
System.out.println(\"Employee name: \" + name);
System.out.println(\"Employee salary: \" + annualSalary);
System.out.println(\"Employee hired year: \" + hiredYear);
System.out.println(\"employee ssn: \" + SSN);
System.out.println();
}
}
and here is my Employeetest program my professor provided( the big thing he said is that I am
not allowed to alter this test program in anyway.

CSE 110 - Lab 6 What this Lab Is About Working wi.docx
CSE 110 - Lab 6
What this Lab Is About:
Working with classes
Problem Description: For this Lab you have to implement a class Person. A person has a
fistname, lastname, address, and birthday year. Supply a constructor and the following methods:
getName(), getAge(), getAddress, and changeAddress(),.
Step 1: Getting Started Create a class called Lab6. Be sure to name your file Lab6.java.
Lab Documentation:
At the beginning of each programming assignment you must have a comment block with the
following information:
/*-------------------------------------------------------------------------
// AUTHOR: your name
// FILENAME: title of the source file
// SPECIFICATION: description of the program
// FOR: CSE 110- Lab #6
// TIME SPENT: how long it took you to complete the assignment //----------------------------------
-------------------------*/
Step 2: Declaring Class
Examining the problem, we need to create a Person class, declare Person class as follows
class Person {
}
Inside the class, declare some data members: a string variable called firstname, a string variable
called lastname, and an integer called birthYear.
// declare some variables of different types:
// an string called firstname
//-->
// a string called lastname
//-->
// a string called address
//-->
// an int called birthYear
//-->
Step 3: Defining the constructor
Remember the constructor assigns input data to the data members.
public Person (String fname, String lname, String
addr, int year)
{
// write the segment of code
//that assigns input data to the data members
}
Step4: Supply the methods
A method called getName() to get the name of an object Person:
public String getName()
{
// write a line of code
//that returns the last name
}
A method called getAge() to get the age of an object Person:
public int getAge(int currentYear)
{
// write a segment of code
//that returns the age
}
A method called getAddress() to get the age of an object Person:
public String getAddress()
{
// write a line of code
//that returns the address
}
A method called changeAddress(String addr) to change the address of an object Person:
public String changeAddress(String addr)
{
// write the segment of code
//that updates the address
}
Step4: Calling the constructor of Person class from the “main” method
In order to use Person class variables and methods we need to have a runner function.
For any class in java, “main” method will be the running method.
You class Lab6 will have the main method.
public class Lab6{
public static void main(String[] args)
{
}
}
In order to use the Person class variables and methods, you need to use the constructor to create
an object Person.
public class Lab6{
public static void main(String[] args)
{
//declare variab.
3. Section 3 � Complete functionality on listing screen (1.5 marks.pdf
3. Section 3 Complete functionality on listing screen (1.5 marks)
a. The starting code includes the definition of a JButton named cmdSortAge, but it is not
shown on the PersonListing screen. Modify the PersonListingScreen to allow it to be shown
b. Add a listener which implements the functionality to sort the list in ascending order of age.
Hints:
i. You should already know how to sort data
ii. Presenting information in a specific order in the table may involve removing all the data
and then re-adding it iii. Data in the table is removed with the command
model.setRowCount(0);- model is an object name that was declared with the starting code. Ie.
model is an object of the class DefaultTableModel.
c. Add a button and an associated listener to sort the list in order of first name .

Team public class Team { private String teamId; priva.pdf
The document contains code defining a Team class with fields for team attributes like ID, name, phone number, etc. and methods to get/set these attributes. It also defines a Game class with fields for game ID, team IDs, date, scores, and methods to get/set these. A Test class is provided to test creating Team and Game objects, reading data from a file to populate them, and check for equality. The Test class calls methods from the other classes to set/get attributes and print output.
So Far I have these two classes but I need help with my persontest c.pdf
So Far I have these two classes but I need help with my persontest class:
The next step is to add method calls for the accessor methods after each input:
//Reading and updating values
System.out.print(\"\ Enter Person Name: \");
person1.setPersonName(sc.nextLine());
System.out.println(\"You entered: \" + person1.getPersonName());
Call the accessor function each time you ask for input, after capturing that input. Then repeat for
a second Person, only this time call the constructor that takes the student id as a parameter.

In your Person classAdd a constant field to store the current yea.pdf
In your Person class:
Add a constant field to store the current year (review the Week 4 Lesson if you aren\'t sure how
to create a constant) :
Assign a value to the current year field when it is declared (do not add it to the constructors).
Add fields to store a person\'s age in years and how many years they have been with the college:
Do not add mutator or accessor methods for these fields.
Set the visibility modifier to private for these fields.
Modify both constructors to set default values for both fields.
Add processing actions:
Add a method to calculate a person\'s age in years only.
Add a method to calculate how long a person has been in college in years only.
Make both methods private.
Do not take any input or display any output in these methods.
Modify the toString() method:
Call the method to calculate the person\'s age.
Call the method to calculate how long the person has been in college.
Add the person\'s age to the String.
Add the person\'s time in college to the String.
Add output messages for each field so that the user knows what they are looking at.
Format the string using the new line escape sequence \ so that each field and it\'s message is on a
separate line.

this collection (array) of People (objects we create in another file) to determine who qualifies for
Social Security benefits. Specifications For our Social Security program we will need two java
files 1. Person java The person class which stores the data for a specific individual 2.
SocialSecurity.java (The driver) Details for these two class files appear below. Person ava UML
diagram name: String birthdate: LocalDate Person0 Person (newName: String, month: int, day:

creates a Person whose name and birthdate are set to null. 2. A parameterized constructor that
accepts a String representation of the name, and three integers corresponding to the month, day,

Cis407 a ilab 4 web application development devry university
This document provides instructions for a lab assignment to build a web application that allows users to submit personnel records to a database and search the database records. The steps include: 1) Creating a Data Layer class with a function to save records to the database. 2) Testing the record submission. 3) Creating datasets and functions to retrieve and display records. 4) Adding buttons to navigate between forms for submission, viewing all records, and searching. 5) Coding the search feature to filter the displayed records based on the search term.
This is the official tutorial from Oracle.httpdocs.oracle.comj.pdf
This is the official tutorial from Oracle.
http://docs.oracle.com/javase/tutorial/jdbc/
Here is a good tutorial for getting started with SQLite.
http://www.tutorialspoint.com/sqlite/sqlite_java.htm
Chapter 34 in the Liang text. He uses MySQL. Getting started with SQLite might be a little
easier, but he does a good job of defining the issues in not too many pages.
For this assignment you can use SQLite OR MySQL.
There are numerous videos in YouTube that demonstrate how to do this. Some are better than
others. When you find one that is helpful, post a link to it on the discussion board.
We have been working with the front-end (GUI), and the middle (creating and manipulating
collections of objects), and now we will add on the back end. The persistent storage of data in
your applications. This exercise is to get you comfortable with connecting to a DB, adding,
deleting, retrieving data. I encourage you to play with this one, do more than the minimum.
SQLite is a very small database. It is included by default in Android and iOS. It is surprisingly
powerful for such a small footprint. It can be frustrating to see what’s going on – what is in the
DB, did the query work correctly? MySQL is often called a community database. It belongs to
Oracle, but they allow anyone to use it for free. The recent versions of the MySQL workbench
that allows you to see what’s going on in your database are really very nice – starting to look like
the Access front end.
Create a connection to a relational database using SQLite or MySQL.
Create a single database table to hold information.
Let’s make a simple class called Person for this exercise.
Person
firstName (String)
lastName(String)
age (int)
ssn (long)
creditCard (long)
Note that once you have the DB created, you don’t want to do this again every time you run your
test program. The easiest way to deal with this – for this assignment, is to comment out the code
that creates the DB creation and the table creation while you experiment with the following.
(Aside: I choose ssn and credit card as fields here so that you might think about the persistent
storage of sensitive data. There are some pretty strict laws governing the storage of some data.
Please don’t use any actual social security numbers or credit card numbers in this exercise.)
Demonstrate the insertion of a record into the database Insert several records.
Write a method called insertPerson(Person person) that adds a person object to your database.
Create another object of type Person, and demonstrate calling your method, passing the object to
the method.
Demonstrate the retrieval of information from the database. Use SQL Select statements, to
retrieve a particular Person from the database.
Write a method called selectPerson that returns a Person object. This method retrieves the data
for a Person from the database. We also need to pass a parameter to identify what person. You
can use ‘name’ if you like, or if you find it easier to use the database generated .
Rd
The toString() method returns a string representation of an object and is useful for debugging. By default, it returns the class name and hash code of an object. Overriding toString() allows you to define a custom string representation. For example, a Person class could override toString() to return the first and last name instead of the default. This provides more meaningful output when printing a Person object.
JavaAssignment6
This document describes an assignment to create a Java application representing a family tree using a JTree. It involves creating a FamilyMember class with attributes like name, age, spouse, children, etc. and methods to get/set values and print information. The application instantiates family members, displays them hierarchically in a JTree, and allows selecting a member to view details. It also implements functions like drag/drop, editing, adding, deleting members and saving the family tree to a file. UML diagrams are included to design the application structure and classes.

Presentation about clean code Scala with counter examples in Java.
Live recording is here http://livestre.am/A1SW (Polish)
Grails queries
The document discusses various querying methods in Grails including dynamic finders, where queries, detached criteria, HQL queries, and performance optimizations. It provides examples of how to use findBy, findWhere, get, count, list and other dynamic finder methods. It also covers where queries, operators, aggregate functions, collections, subqueries, bulk updates/deletes, criteria queries, and HQL queries. It discusses returning different result types and filtering query results. Lastly, it mentions caching and performance techniques.
Refer to my progress on this assignment belowIn this problem you w.pdf
Refer to my progress on this assignment below
In this problem you will make it “more” object-oriented in the following ways:
-You will change its name to SortedList
-You will change the constructor that takes no arguments to be more traditional and initialize the
member fields to dummy values.
-You will add a constructor that takes in an initialized array and a size
-You will add an insert function that adds a value to the list and maintains its sorted-ness
-You will add a quicksort function check the below code.
-You will make updates as necessary to the main function so that it still runs and tests your code.
The code below seems to sort correctly but it skips over some items in the array and I am not
sure what is happening. Please help! Thanks!

//the whole program that you wrote is correct except one line , when you call the quicksort

1. Section1.- Populating the list of persons on the person listing f.pdf
The document provides starter code for a GUI application to manage a list of persons and their details. It outlines 4 sections of work to complete the application:
1. Populate the person listing with data from a file and add functionality to add new persons.
2. Modify the person entry form and add functionality to save new persons.
3. Add sorting buttons and functionality to the person listing.
4. Customize the color scheme of the person listing form.
The assistant is asked to review the code, complete the outlined functionality, and submit the completed Java files in a zip file. Non-functional criteria around GUI integration, component addition, and listener implementation will also be considered in the evaluation.
• Sexual orientation is often framed on a binary-gay OR straight; ho.pdf
• Sexual orientation is often framed on a binary-gay OR straight; homosexual OR heterosexual.
Why can sexual orientation be thought of as a continuum?
Solution
Sexual orientation is a psychological or physiological understanding of sexuality in humans.It is
thought of as a continuum as it undergoes a gradual transition from heterosexuality to
homosexuality.There could exist sexual attraction towards opposite sex (heterosexual)
exclusively at one end or attraction towards same sex (homosexual) exclusively at the other end..
You heated the samples containing your cheek cells. Think carefully .pdf
You heated the samples containing your cheek cells. Think carefully about where this DNA was
packaged in your cells, and what high temperatures usually do to enzyme structure and function.
(Hint: Lysosomes contain enzymes known as DNAses!) What functions do you think these high
temperature incubations served in your DNA extractions?
Solution
The DNA is present in the nucleus of the cell, i.e. enclosed in the nuclear membrane. At high
temperatures, the membrane of organelles is break-down. The breakup of lysosomal membrane
result in leakage of lysosomal enzymes, which break down the other organelles. But at higher
temperatures, these enzymes become functionally inactive as they become denatured upon
exposure to higher temperatures. So, the DNAases cannot break down DNA, and it can be
extracted out..

Problem Description: For this Lab you have to implement a class Person. A person has a
fistname, lastname, address, and birthday year. Supply a constructor and the following methods:
getName(), getAge(), getAddress, and changeAddress(),.
Step 1: Getting Started Create a class called Lab6. Be sure to name your file Lab6.java.
Lab Documentation:
At the beginning of each programming assignment you must have a comment block with the
following information:
/*-------------------------------------------------------------------------
// AUTHOR: your name
// FILENAME: title of the source file
// SPECIFICATION: description of the program
// FOR: CSE 110- Lab #6
// TIME SPENT: how long it took you to complete the assignment //----------------------------------
-------------------------*/
Step 2: Declaring Class
Examining the problem, we need to create a Person class, declare Person class as follows
class Person {
}
Inside the class, declare some data members: a string variable called firstname, a string variable
called lastname, and an integer called birthYear.
// declare some variables of different types:
// an string called firstname
//-->
// a string called lastname
//-->
// a string called address
//-->
// an int called birthYear
//-->
Step 3: Defining the constructor
Remember the constructor assigns input data to the data members.
public Person (String fname, String lname, String
addr, int year)
{
// write the segment of code
//that assigns input data to the data members
}
Step4: Supply the methods
A method called getName() to get the name of an object Person:
public String getName()
{
// write a line of code
//that returns the last name
}
A method called getAge() to get the age of an object Person:
public int getAge(int currentYear)
{
// write a segment of code
//that returns the age
}
A method called getAddress() to get the age of an object Person:
public String getAddress()
{
// write a line of code
//that returns the address
}
A method called changeAddress(String addr) to change the address of an object Person:
public String changeAddress(String addr)
{
// write the segment of code
//that updates the address
}
Step4: Calling the constructor of Person class from the “main” method
In order to use Person class variables and methods we need to have a runner function.
For any class in java, “main” method will be the running method.
You class Lab6 will have the main method.
public class Lab6{
public static void main(String[] args)
{
}
}
In order to use the Person class variables and methods, you need to use the constructor to create
an object Person.
public class Lab6{
public static void main(String[] args)
{
//declare variab.

3. Section 3 Complete functionality on listing screen (1.5 marks)
a. The starting code includes the definition of a JButton named cmdSortAge, but it is not
shown on the PersonListing screen. Modify the PersonListingScreen to allow it to be shown
b. Add a listener which implements the functionality to sort the list in ascending order of age.
Hints:
i. You should already know how to sort data
ii. Presenting information in a specific order in the table may involve removing all the data
and then re-adding it iii. Data in the table is removed with the command
model.setRowCount(0);- model is an object name that was declared with the starting code. Ie.
model is an object of the class DefaultTableModel.
c. Add a button and an associated listener to sort the list in order of first name .

Team public class Team { private String teamId; priva.pdf
The document contains code defining a Team class with fields for team attributes like ID, name, phone number, etc. and methods to get/set these attributes. It also defines a Game class with fields for game ID, team IDs, date, scores, and methods to get/set these. A Test class is provided to test creating Team and Game objects, reading data from a file to populate them, and check for equality. The Test class calls methods from the other classes to set/get attributes and print output.
So Far I have these two classes but I need help with my persontest c.pdf
So Far I have these two classes but I need help with my persontest class:
The next step is to add method calls for the accessor methods after each input:
//Reading and updating values
System.out.print(\"\ Enter Person Name: \");
person1.setPersonName(sc.nextLine());
System.out.println(\"You entered: \" + person1.getPersonName());
Call the accessor function each time you ask for input, after capturing that input. Then repeat for
a second Person, only this time call the constructor that takes the student id as a parameter.

In your Person classAdd a constant field to store the current yea.pdf
In your Person class:
Add a constant field to store the current year (review the Week 4 Lesson if you aren\'t sure how
to create a constant) :
Assign a value to the current year field when it is declared (do not add it to the constructors).
Add fields to store a person\'s age in years and how many years they have been with the college:
Do not add mutator or accessor methods for these fields.
Set the visibility modifier to private for these fields.
Modify both constructors to set default values for both fields.
Add processing actions:
Add a method to calculate a person\'s age in years only.
Add a method to calculate how long a person has been in college in years only.
Make both methods private.
Do not take any input or display any output in these methods.
Modify the toString() method:
Call the method to calculate the person\'s age.
Call the method to calculate how long the person has been in college.
Add the person\'s age to the String.
Add the person\'s time in college to the String.
Add output messages for each field so that the user knows what they are looking at.
Format the string using the new line escape sequence \ so that each field and it\'s message is on a
separate line.

This is the official tutorial from Oracle.

Here is a good tutorial for getting started with SQLite.
http://www.tutorialspoint.com/sqlite/sqlite_java.htm
Chapter 34 in the Liang text. He uses MySQL. Getting started with SQLite might be a little
easier, but he does a good job of defining the issues in not too many pages.
For this assignment you can use SQLite OR MySQL.
There are numerous videos in YouTube that demonstrate how to do this. Some are better than
others. When you find one that is helpful, post a link to it on the discussion board.
We have been working with the front-end (GUI), and the middle (creating and manipulating
collections of objects), and now we will add on the back end. The persistent storage of data in
your applications. This exercise is to get you comfortable with connecting to a DB, adding,
deleting, retrieving data. I encourage you to play with this one, do more than the minimum.
SQLite is a very small database. It is included by default in Android and iOS. It is surprisingly
powerful for such a small footprint. It can be frustrating to see what’s going on – what is in the
DB, did the query work correctly? MySQL is often called a community database. It belongs to
Oracle, but they allow anyone to use it for free. The recent versions of the MySQL workbench
that allows you to see what’s going on in your database are really very nice – starting to look like
the Access front end.
Create a connection to a relational database using SQLite or MySQL.
Create a single database table to hold information.
Let’s make a simple class called Person for this exercise.
Person
firstName (String)
lastName(String)
age (int)
ssn (long)
creditCard (long)
Note that once you have the DB created, you don’t want to do this again every time you run your
test program. The easiest way to deal with this – for this assignment, is to comment out the code
that creates the DB creation and the table creation while you experiment with the following.
(Aside: I choose ssn and credit card as fields here so that you might think about the persistent
storage of sensitive data. There are some pretty strict laws governing the storage of some data.
Please don’t use any actual social security numbers or credit card numbers in this exercise.)
Demonstrate the insertion of a record into the database Insert several records.
Write a method called insertPerson(Person person) that adds a person object to your database.
Create another object of type Person, and demonstrate calling your method, passing the object to
the method.
Demonstrate the retrieval of information from the database. Use SQL Select statements, to
retrieve a particular Person from the database.
Write a method called selectPerson that returns a Person object. This method retrieves the data
for a Person from the database. We also need to pass a parameter to identify what person. You
can use ‘name’ if you like, or if you find it easier to use the database generated .
Rd
The toString() method returns a string representation of an object and is useful for debugging. By default, it returns the class name and hash code of an object. Overriding toString() allows you to define a custom string representation. For example, a Person class could override toString() to return the first and last name instead of the default. This provides more meaningful output when printing a Person object.
JavaAssignment6
This document describes an assignment to create a Java application representing a family tree using a JTree. It involves creating a FamilyMember class with attributes like name, age, spouse, children, etc. and methods to get/set values and print information. The application instantiates family members, displays them hierarchically in a JTree, and allows selecting a member to view details. It also implements functions like drag/drop, editing, adding, deleting members and saving the family tree to a file. UML diagrams are included to design the application structure and classes.

Grails queries
The document discusses various querying methods in Grails including dynamic finders, where queries, detached criteria, HQL queries, and performance optimizations. It provides examples of how to use findBy, findWhere, get, count, list and other dynamic finder methods. It also covers where queries, operators, aggregate functions, collections, subqueries, bulk updates/deletes, criteria queries, and HQL queries. It discusses returning different result types and filtering query results. Lastly, it mentions caching and performance techniques.
Refer to my progress on this assignment belowIn this problem you w.pdf
Refer to my progress on this assignment below
In this problem you will make it “more” object-oriented in the following ways:
-You will change its name to SortedList
-You will change the constructor that takes no arguments to be more traditional and initialize the
member fields to dummy values.
-You will add a constructor that takes in an initialized array and a size
-You will add an insert function that adds a value to the list and maintains its sorted-ness
-You will add a quicksort function check the below code.
-You will make updates as necessary to the main function so that it still runs and tests your code.
The code below seems to sort correctly but it skips over some items in the array and I am not
sure what is happening. Please help! Thanks!

• Sexual orientation is often framed on a binary-gay OR straight; ho.pdf
• Sexual orientation is often framed on a binary-gay OR straight; homosexual OR heterosexual.
Why can sexual orientation be thought of as a continuum?
Solution
Sexual orientation is a psychological or physiological understanding of sexuality in humans.It is
thought of as a continuum as it undergoes a gradual transition from heterosexuality to
homosexuality.There could exist sexual attraction towards opposite sex (heterosexual)
exclusively at one end or attraction towards same sex (homosexual) exclusively at the other end..
You heated the samples containing your cheek cells. Think carefully .pdf
You heated the samples containing your cheek cells. Think carefully about where this DNA was
packaged in your cells, and what high temperatures usually do to enzyme structure and function.
(Hint: Lysosomes contain enzymes known as DNAses!) What functions do you think these high
temperature incubations served in your DNA extractions?
Solution
The DNA is present in the nucleus of the cell, i.e. enclosed in the nuclear membrane. At high
temperatures, the membrane of organelles is break-down. The breakup of lysosomal membrane
result in leakage of lysosomal enzymes, which break down the other organelles. But at higher
temperatures, these enzymes become functionally inactive as they become denatured upon
exposure to higher temperatures. So, the DNAases cannot break down DNA, and it can be
extracted out..

Staphylococcus expresses many potential virulence factors. They are :
(1) surface proteins that induces colonization of host tissues
(2) invasins that helps in bacterial spread in tissues (leukocidin, kinases, hyaluronidase);
(3) surface factors that resist phagocytic engulfment (capsule, Protein A);
(4) biochemical properties that increase their chance of survival in phagocytes (carotenoids,
catalase production);
(5) immunological disguises like Protein A, coagulase;
(6) membrane-damaging toxins that lyse eucaryotic cell membranes (hemolysins,leukotoxin,
leukocidin;
(7) exotoxins that destroy host tissues or provoke symptoms of disease (SEA-G, TSST, ET);
(8) inherent and acquired resistance to antimicrobial agents
Streptococcus pyogenes (Group A streptococcus) expresses the following virulence factors :
(1) M protein, fibronectin-binding protein (Protein F) and lipoteichoic acid that help in adherence
(2) hyaluronic acid capsule which acts as an immunological disguise and inhibits phagocytosis;
(3) invasins such as streptokinase, streptodornase (DNase B), hyaluronidase, and streptolysins;
(4) exotoxins, such as pyrogenic (erythrogenic) toxin which forms the rash of scarlet fever and
systemic toxic shock syndrome.
Streptococcus agalactiae ( Group B streptococcus ) expresses the following virulence factors :
(1) capsular polysaccharides, which confer serotype specificity to GBS
(2) C proteins and other related surface proteins
(3) Pilins function as adhesins, promote CNS entry, and enhance biofilm formation
(4) a pore-forming toxin, -hemolysin, that today is considered identical to the GBS pigment
Group D Streptococci have been reclassified and placed in the genus Enterococcus. The
virulence factors are :
(i) adherence to host tissues facilitated by aggregation substance, surface carbohydrates, or
fibronectin-binding moieties
(ii) invasion and abscess formation,
(iii) factors potentially relevant to modulation of host inflammatory responses,
(iv) potentially toxic secreted products
(v) Extracellular toxins such as cytolysin can induce tissue damage
The pneumococcus virulence factors are :
(1) the choline-binding proteins;
(2) pneumococcal surface proteins A and C (PspA and PspC);
(3) the LPXTG-anchored neuraminidase proteins; hyaluronate lyase (Hyl);
(4) pneumococcal adhesion and virulence A (PavA);
(5) enolase (Eno); pneumolysin; autolysin A (LytA)
The virulence factors of Neisseria meningitidis are :
(1) Capsules whose presence provide resistance against antibody, complement-mediated, or
phagocytic destruction by the host i.

Please answer the question fully and correctly.
Solution
because they are cosmopolitan in distribution, exploit a broad spectrum of food and out number
all other mammals. When humans ceased to be hunter gatherers and instead became farmers,
their lives and those of rats became intimately connected. Humans learned to grow and store
grain, and rats learned it was easier to feed off these stores than to fend for themselves. They also
discovered that human dwellings provided excellent shelter from the elements..

A. Instant messaging (IM) has the capability for scripting, which is one reason it is dangerous for
the organization. Answers B, C, and D do not properly answer the question because they are all
reasons why IM is vulnerable. IM can bypass corporate firewalls, most versions lack encryption,
and IM uses insecure password management.

What tissue type has polarity and is avascular
What tissue type has polarity and is avascular
Solution
The epithelial tissue do not receive vascular supply, so they are avascular. It is polar because it
contains apical, lateral and basal membrane domains.
The epithelial tissues form the sheet like outer covering of the body surfaces and provide
protection to the organs. One surface of this epithelial tissue is not bound to anything and
produces glandular secretions, also involved in absorption process.
The characteristics of the epithelial tissues include the following:
1). Cells undergo frequent cell division
2). Lack of blood vessels
3). Cells are tightly packed by cell junctions..

What is meant by modular software and why is it important How can t.pdf
What is meant by modular software and why is it important? How can the modularity of a
program code be quantifiably measured?
Solution
1) What is ment by modular software and why is it important?
Answer:-
How important is modularization of software projects:
Modularization is obviously important in software projects, but I want to know people\'s
opinions on how important and for what reasons it is important. I\'ve obviously got my own ideas
since I\'m asking this, but think of it like a \"common brainstorm\" of the reasons one should
modularize one\'s software projects..
Techopedia explains Modular Programming:
1) Modules in modular programming enforce logical boundaries between components and
improve maintainability. They are incorporated through interfaces. They are designed in such a
way as to minimize dependencies between different modules. Teams can develop modules
separately and do not require knowledge of all modules in the system.
2) Each and every modular application has a version number associated with it. This provides
developers flexibility in module maintenance. If any changes have to be applied to a module,
only the affected subroutines have to be changed. This makes the program easier to read and
understand.
3) Modular programming has a main module and many auxiliary modules. The main module is
compiled as an executable (EXE), which calls the auxiliary module functions.
2) How can the modularity of a program code be quantifiably measured?
Answer:-
A Software Metric is a standard of measure of a degree to which a software system or process
possesses some property. Even if a metric is not a measurement (metrics are functions, while
measurements are the numbers obtained by the application of metrics), often the two terms are
used as synonymous.
A Software development goal is obtaining objective, reproducible and quantifiable
measurements, which may have numerous valuable applications in schedule and budget
planning, cost estimation, quality assurance testing, software debugging, software performance
optimization, and optimal personnel task assignments..
What are the two major steps in biological classification What .pdf
What are the two major steps in biological classification? What did Linnaeus contribute to
taxonomy? are scientific names derived? want to identify the various
Solution
Answers:
1. Two major steps in biological classification are:
a) Defining and describing organisms
b) Arranging organisms into a logical classification scheme
2. The binomial nomenclature system was introduced by Carolus Linnaeus. It is used to assign
each organism a two part scientific name - genus and species.
3. Scientific names are derived following the universal rules of nomenclature:
a) These are in Latin and written in italics.
b) The first word represents the genus while the second word is the species epithet
c) The first word (genus) is written in capital letter while second word (species) is written in
small letter.
d) If hand written, they are separately underlined, or printed in italics to denote their Latin origin..
Tissue transplant rejection is primarily atype I reaction.type I.pdf
Tissue transplant rejection occurs when the host immune system reacts to antigens in the transplanted organ from a foreign organism. This is a type IV hypersensitivity reaction where T-cells mediate an immune response against the major histocompatibility complex proteins on the surface of donated tissue that help the immune system identify foreign substances. Tissue transplant rejection can take weeks to months to occur as an immune response against the transplanted organ.
The members of the UN peace committee, must choose, from among thems.pdf
The members of the UN peace committee, must choose, from among themselves, a presiding
officer of their committee. For each member x, let f(x) designate that member\'s choice for
officer. If no two members vote alike, what is the range of f?
Solution
Since each member can vote only for one person and no two members vote alike
the mapping f: x to f(x) is one to one and onto.
Hence f is a bijective function
So order of x = order of f(x)
Or Range of f = No of members of the UN Peace committee.
NetWork Design Question1a.) In writing a letter to a Friend, what .pdf
NetWork Design Question
1a.) In writing a letter to a Friend, what do you hace to do to get the letter to your friend. List all
the steps and ways.
1b.) Relate the stages of letter transaction to the layers of the internet.
Solution
In writing a letter to a Friend, the following 5 steps do you face to get the letter to your friend.
1) Application layer:
TCP/IP: A user retrieves a Web page from a server in somewhere by typing a URL into a
browser and clicking the enter key.
The server receives the request, finds the page on its hard drive and sends it back to the user.
Neither the user nor the client or server software is aware of the way the messages were
delivered. There are many application layer protocols.
2) Transport layer:
TCP/IP: Transport layer software establishes a connection between a client and server then
monitors that connection for errors.
It also slows transmission if it gets too fast to handle at the other end. Transport layer software is
not concerned with how the data is actually moved from one point to the other that is the
responsibility of lower level software. There are two transport layer protocols TCP (reliable) and
UDP (unreliable, but fast).
If TCP tries repeatedly and errors persist, it informs its \"boss,\" the application program.
3) Internet layer:
TCP/IP:Internet layer programs move data between networks. IP is the internet layer protocol.
IP software ignores the data, and it does the same thing with a packet whether it comes from the
friend or your mother.
Once the data gets to its destination local area network (LAN), it is handed over to data link layer
software or firmware for delivery to the proper computer.
4) Data link layer:
TCP/IP:Data Link layer programs move (incoming and outgoing) data within LANs.
Ethernet is the most common data link protocol. A data link program is not concerned with how
outgoing data will be handled once it leaves the LAN or how incoming data got there. That is the
responsibility of the internet layer software.
5) Physical layer:
TCP/IP:Physical layer protocols specify the means of representing ones and zeros (bits).
The method of transmitting them between two points using wire, radio, fiber, etc. is also
specified. There are many ways to make ones and zeros and many ways to transmit them so there
are many physical layer protocols..

My question is pretty simple, I just want to know how to call my ope.pdf
My question is pretty simple, I just want to know how to call my operator== function in
Stack.cpp using a list function.
Here is what I meant. This is my Stack.h file:
class Stack {
public:
/**constructors and destructors*/
Stack();
Stack(const Stack &S);
~Stack();
void pop();
void push(int data);
bool operator==(const Stack &S);
[ .......]
private:
List stack;
};
Here is my List.h file:
template
class List {
private:
struct Node {
listitem data;
Node* next;
Node* previous;
Node(listitem data) :
next(NULL), previous(NULL), data(data) {
}
};
typedef struct Node* NodePtr;
NodePtr start;
NodePtr end;
NodePtr cursor;
int length;
public:
........
bool operator==(const List &list);
[.......] }
[........]
template
bool List::operator==(const List& list) {
if (length != list.length)
return false;
NodePtr temp1 = start;
NodePtr temp2 = list.start;
while (temp1 != NULL) {
if (temp1->data != temp2->data)
return false;
temp1 = temp1->next;
temp2 = temp2->next;
}
return true;
}
[......]
So I already define my functions in List.h and I only need to call my function from List again in
my Stack.cpp file. For example from my Stack.cpp:
Stack::Stack(const Stack &S) :
stack(S.stack) {
}
void Stack::pop() {
stack.remove_start();
}
[......]
And I don\'t know how to call my operator== function in Stack.cpp from the List.h like the way
above. This is what my guess so far but did not work:
bool Stack::operator==(const Stack &S) {
stack.operator==(S.stack);
}
Thank you
Solution
When we wish to make a comparison, such as in an if statement, we use the double equals sign
(==).
1)bool operator==(const Stack &S); [ .......]
It means whatever the boolean operator it should be belongs to stack or equal to.
2) bool operator==(const List &list);
Likewise link list also compare with the constructor link list.
and constructor need not to call explicitly. it will call itself when program called first..

Irreducible polynomials over a field F play a similar, in a certain .pdf
Irreducible polynomials over a field F play a similar, in a certain sense, role in F[x] to the role
the prime numbers play for Z. Using your favorite proof of the existence of an infinite number of
primes as inspiration, please prove that there are infinitely many irreducible polynomials over a
field F.
Solution
if there were finite such polynomials.... p1.p2.p3.........pn
then
p1 * p2 * p3 * ......pn +1 (multiplicative unity) is a polynomial
which is either irreducible or can be written as a product of irreducible polynomials.
It cannot be irreducible since it is different from the set of irreducibles.
Also it cannot be divisible by any irreducible . Say it does pi divides this new polynomial fr
some i , then
pi divides p1*p2*......pn + 1
and also pi is one of p1,p2....pn so divides p1*p2*....pn
hence it divides 1
contradiction.

By Dr. Vinod Kumar KanvariaHow to Fix the Import Error in the Odoo 17
An import error occurs when a program fails to import a module or library, disrupting its execution. In languages like Python, this issue arises when the specified module cannot be found or accessed, hindering the program's functionality. Resolving import errors is crucial for maintaining smooth software operation and uninterrupted development processes.
A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

In an education system, it is understood that assessment is only for the students, but on the other hand, the Assessment of teachers is also an important aspect of the education system that ensures teachers are providing high-quality instruction to students. The assessment process can be used to provide feedback and support for professional development, to inform decisions about teacher retention or promotion, or to evaluate teacher effectiveness for accountability purposes.

You will need to develop a system that can track employee informatio.pdf
- 1. You will need to develop a system that can track employee information for two Organizations (such as Google and Microsoft). The Employee information you must track is as follows: Name Gender Job Title Organization they work for Birthday As for the Organization that the Employee works for, you must also track this information: Organization Name Number of Employees The system must be able to properly compare any two employees against each other to determine if they are the same Employee. This means that if you compared two Employees with the same Name, Gender, Birthday and Organization, the system should think that they are equal to one another. If any of these properties are different, then the two Employees are not the same Employee. The same rules apply to comparing Organizations to one another. Organizations with the same Organization name are to be thought of as equal, different names means different organizations. Use the charts on the next page to create your classes. Employee private String name; private String gender; private String jobTitle; private Organization organization; private String birthDate; Employee(String theName, String theGender, String title, Organization org, String theBirthDate) <> String getName() String getGender() String getJobTitle() Organization getOrganization() String getBirthDate() String toString() boolean equals(Employee other)
