Understanding java streams
The document discusses Java streams and I/O. It defines streams as abstract representations of input/output devices that are sources or destinations of data. It describes byte and character streams, the core stream classes in java.io, predefined System streams, common stream subclasses, reading/writing files and binary data with byte streams, and reading/writing characters with character streams. It also covers object serialization/deserialization and compressing files with GZIP.
Write a program that will count the number of characters- words- and l.docx
Write a program that will count the number of characters, words, and lines in a file. Words are separated by whitespace characters. The file name should be passed as a command-line argument, as shown;
c:\\exercise>java Exercise12_13 Loan.java
File Loan.java has
1919 characters
210 words
71 lines

Java Programming - 06 java file io
Module 06 covers Java file input/output (IO) including byte streams, character streams, listing and creating directories and files, deleting directories and files, and using the Java console. Key topics include IO streams for input and output, using byte streams like FileInputStream and FileOutputStream to copy file bytes, character streams like BufferedReader and BufferedWriter to copy file lines, listing and interacting with directory objects, creating/deleting files and directories, and using the Java console for password input. The module provides examples of reading/writing files using byte and character streams, listing directory contents, creating/deleting files and directories, and taking password input from the console.
Java file
The document contains 17 code snippets that demonstrate various Java programming concepts like loops, arrays, methods, classes, input/output, etc. Specifically, the code snippets show:
1. Using for loops to print numeric series
2. Accepting user input of different data types using Scanner and parsing
3. Using StringTokenizer and Scanner classes
4. Finding largest number among 3 inputs and printing tables
5. Demonstrating 2D arrays, array of objects, and command line arguments
6. Various String class methods like length(), substring(), indexOf() etc.
Java file
The document contains 21 programming problems involving Java concepts like arrays, loops, methods, classes, objects, constructors, and more. For each problem, source code is provided to demonstrate how to solve the problem, followed by sample output. Some key problems include: (1) printing series using nested loops, (2) receiving user input of different data types, (3) using StringTokenizer and Scanner classes, (4) finding largest of 3 numbers, (5) using 2D arrays and array of objects.

Computer programming 2 chapter 1-lesson 2
This document discusses Java input and output. It explains that System.out.println(), System.out.print(), and System.out.printf() can be used for output. println() prints the string and moves to the next line, print() prints the string, and printf() provides string formatting. The Scanner class is used for input, by creating a Scanner object and calling methods like nextInt() and nextDouble(). Examples demonstrate getting integer, float, double, and string input from the user.

Java ppt
This document discusses various Java concepts like object-oriented programming, compilation, the main method signature, command line arguments, byte code checking, type casting, and input/output in Java using classes like DataInputStream and Scanner. It provides code examples for accepting user input using these classes and parsing the input into different data types like integer and float. It also compares DataInputStream and Scanner, noting that Scanner avoids the need to manually convert input types.
Java practical
The document provides code examples for several Java programming concepts:
1. A program that takes command line arguments, calculates the sum and average of the numbers passed, and displays the results.
2. A Student class with member functions to read and display student details like name and age.

PLEASE HELP IN C++For this test, you will need to create the follo.pdf
PLEASE HELP IN C++
For this test, you will need to create the following function. First add the function prototype to
person.h, then put the function implementation in person.cpp and finally invoke/test the function
in main.cpp. Please label your output clearly. E.g. After adding a person, the list is:
Create a function to read a persons information and insert into the list at a given position. The
function returns true if the insertion is successful and it returns false if the array is out of
capacity.
bool addPerson(PersonType list[], int &count);
Sample code in person.cpp
PersonType aPerson;
//read in person name, person citizenship, and age and populate aPerson
//e.g strcpy(aPerson.name, tempName)
//read position to insert inside the function - see sample //run
//position could be read from the user or you could set a //number that is not more than count. If
you read from the //user, check to make sure position is not > than count.
//shift and insert aPerson in the right position
Sample test code in main.cpp
if(addPerson(list, count) == true)
{output list}
You must be able to read cstrings with spaces.
You must not replace any existing values in the list. You must shift and insert in the right
position. See zybooks Lab 11.9 for reference.
You must be able to add at the beginning of the list and at the end - if your list has 4 elements,
users must be able to insert at position 0 through 4.
See Sample Runs below and test your code multiple times adding users at the beginning and at
the end.
You must make sure the position is within count.
You must check for unreasonable age (for example: age < 1 and age > 100 can be unreasonable).
Include a welcome and goodbye message. (See sample run below).
Must use all the given function prototypes under Task exactly as is. Function Prototypes and
implementations must be written in the appropriate files.
Do not add header comments for this exam, but you must have function comments for the
function you are writing.
Do not use containers of any sort or any vectors for this program. Use only the concepts we have
learned so far.
Criteria for Success
Test your program using the following sample runs, making sure you get the same output when
using the given inputs (in blue):

Computer programming 2 chapter 1-lesson 2
This document discusses Java input and output. It explains that System.out.println(), System.out.print(), and System.out.printf() can be used for output. println() prints the string and moves to the next line, print() prints the string, and printf() provides string formatting. The Scanner class is used for input, by creating a Scanner object and calling methods like nextInt() and nextDouble(). Examples demonstrate getting integer, float, double, and string input from the user.

please! 1. Match and pair the following basic genetic conce.pdf
please!
1. Match and pair the following basic genetic concepts with their respective
descriptions/definitions: 1. Gene a. Two different alleles 2. Allele b. Observable heritable feature
that may vary among organisms. 3. Phenotype c. Two identical alleles 4. Genotype d. Describes
the specific alleles present in the offspring. 5. Homozygous e. Segments of DNA responsible for
producing a particular trait. 6. Heterozygous f. Variants of a gene present for a particular
character. 2. From the figure presented here, determine the following: a. Which letter(s) show a
phenotype? b. Which letter(s) show a genotype? c. In letter (c), are we looking at a homozygous
recessive, a homozygous dominant, or a heterozygous individual? d. In letter (e), are we looking
at a homozygous recessive, a homozygous dominant, or a heterozygous individual?
3. A and a are dominant and recessive alleles, respectively, of the same gene. Which genotype(s)
would result in an individual with the dominant trait? A) AA and aa B) AA and aa C) only AA
D) AA and Aa E) only Aa 4. For Labrador retrievers, black fur color (B) is dominant to yellow
fur color (b). If a heterozygous black male mated with a homozygous yellow female, what would
the puppies look like? Determine the phenotypic ratios. - Step 1: Determine the genotype of the
female and male Labradors. Heterozygous black male: Homozygous yellow female: - Step 2:
Write/Type the cross between the two Labradors. X -Step 3: Do a Punnett Square to determine
the probable genotypes for the offspring and to determine the phenotypic ratio.
-Step 4: Determine the Phenotype ratios of the progeny: s. There are many humans traits that are
fairly simple and that follow the Mendelian pattern of inheritance. However, most of our traits
are much more complex, involving many genes or interactions between genes. For example, hair
color is determined by at least four genes, each one coding for the productions of melanin, a
brown pigment. Because the effect of these genes is cumulative, hair color can range from
blonde (little melanin) to very dark brown (much melanin). 2 Human traits are of great interest to
us and there are few traits that seem to exhibit Mendelian inheritance, such as the ones shown
below (this can be found in your lab manual). Figure 134 some madiy absenutle human
Menoulae tak. Mid-digital hair b. Tongue rolling c. Widow's peak d. Earlobe attachment e.
Hitchhiker's thumb f. Relative finger length With the information provided in your lab manual,
