Create a text file named lnfo.txt. Enter the following informatio.pdf
The document describes a Java program that takes user input of a name, address, and phone number and writes it line by line to a text file. The program runs in a continuous loop prompting for input until the user enters "Exit" for the name, at which point it closes the file and exits the program.
FileHandling.docx
The document discusses file operations in Java, including creating, reading from, writing to, and deleting files. It also covers file streams and the File class methods. The main file operations covered are creating a new file, getting file information like name and size, writing content to a file, reading the file's content, and deleting the file.
Python programming : Files
The document discusses files in Python. It defines a file as an object that stores data, information, settings or commands used with a computer program. There are two main types of files - text files which store data as strings, and binary files which store data as bytes. The document outlines how to open, read, write, append, close and manipulate files in Python using functions like open(), read(), write(), close() etc. It also discusses pickling and unpickling objects to binary files for serialization. Finally, it covers working with directories and running other programs from Python.

Write a java program that allows the user to input the name of a fil.docx
The document describes a Java program that takes in a file containing positive integers, reads the integers, separates the even and odd numbers, and writes them to separate text files. The program prompts the user to enter the file name and number of integers, then uses loops and conditionals to read each integer, check if it is even or odd, and write it to the corresponding file. On completion, it notifies the user that the files were successfully written.

This is a java lab assignment. I have added the first part java re.pdf
This is a java lab assignment. I have added the first part \"java retail class\" at the bottom. I am
unsure how to read the txt file into an array from the retail class. The stock txt file has been
added also.
A beginning framework and inventory list has been provided to you to use your Retail Item Class
as an array. Develop a program to accomplish the following menu items that can be selected by
the end user. Discussion of what each menu item should do is provided below the menu item.
Modify your object class file as desired. Please append initials to files created. Use Select-Case
for menu choices and methods to perform those choices. Please make a selection: 1. Open
Inventory File (This should ask the user for the file name, open the file and load the data into the
object array). 2. Display All (This should show a table of all items and data) 3. Display Reorder
Only (This should show only the stock number, Description and current quantity for items
requiring reorder) 4. Find Stock number (Allows the user to enter part of the description and
displays all matching stock numbers and descriptions matching that - case insensitive, such as
“cubs” or “cubs”) 5. Display Stock number (Allows user to enter stock number and displays
record of item) 6. Add Quantity (Asks for stock number and quantity for units, adds it to current,
displays record results) 7. Subtract Quantity (Asks for stock number and quantity, subtracts,
displays results including if reorder is needed.) 8. Change Price (Asks for stick number, changes
price to provided value, display results). 9. New Item (Allows adding a new item, updates count.
Display record results). 10. Save Inventory File (asks user for file name, save all inventory to
that file in a format that can be read back.)

In Java- Input is from a file- The input is all doubles- You are to in.pdf
The program reads in doubles from a file two at a time, uses those values to create Rectangle objects with a length and width, calculates the area of each rectangle, and outputs the rectangle with the largest area. It creates and initializes a Rectangle for the first input values as the largest so far, then loops to continue reading input and creating rectangles, comparing each new one to the current largest by area and updating the largest if a bigger one is found.

The problem is called Name Search and it has to be in C# 6. .pdf
The document describes a C# program that searches for names in two text files containing lists of the most popular boy and girl names from 2000-2009. The program loads the names into lists from the text files, then allows the user to search for a boy's name, girl's name, or both. It will display whether the searched names were among the most popular or not.
Python IO
File handling in Python allows storing and retrieving data from files. There are two types of data - persistent data stored permanently in files, and transient temporary data. Files can contain text or binary data. The os module allows creating, renaming, removing directories and listing their contents. Files can be opened in different modes like read, write, append to perform operations like writing, reading, copying and retrieving metadata. Objects can also be serialized into files and deserialized later for storage. The with statement automatically closes files after operations.

A Java class that allows writing to files is Class FileWriter. This class is a part of java.io package and extends (inherits from) OutputStreamWriter class.
This class allows us to write character files conveniently. The reason I chose this class is because of the functionality provided by FileWriter class. It allows us to write to a new file, as well as append content to an existing file. Given a filename as a string parameter, it creates the file if it does not already exist. So, the user is not required to explicitly create a new file before writing to it using FileWriter class.
FileWriter class provides several constructors, which are as follows:
1) FileWriter(File file) - takes File object as a parameter, which corresponds to the file, the data is to be written to.
2) FileWriter(File file, boolean append) - takes two parameters: one is the File object to which data is to be written to, and second is a boolean parameter which indicates whether data is to be appended to the file
3) FileWriter(String filename) - takes a string parameter for the filename
4) FileWriter(String filename, Boolean append) - takes two parameters, one for the filename (string) and a Boolean value indicating whether data should be appended to the file or not
Pseudo code:
1. Create a string array and initialize elements of the array with given data
String[] dataArray = new String[4];
dataArray[0] = "1001 Jennifer Ward SUPPLIES 2140.20 BOOKS 5200.10 PAPER 455.23 NORTH Phone";
dataArray[1] = "1003 Athena Andrews SUPPLIES 5155.55 BOOKS 6300.50 PAPER 223.25 SOUTH Email";
dataArray[2] = "1005 Andy Smith SUPPLIES 6155.55 BOOKS 300.50 PAPER 55.55 SOUTH Email";
dataArray[3] = "1006 Robert Stearns SUPPLIES 7255.55 BOOKS 8300.50 PAPER 77.77 SOUTH Phone";
2. Create a File object and pass the filename
File file = new File(“data.txt”);
3. Check if file exits by that name, if it does not create a new file as follows:
file.createNewFile();
4. Create FileWriter object by passing the File object created above
5. In a for loop write each element of the array to the file:
for(int i=0; i<dataArray.length; i++){
writer.write(dataArray[i]); //write the line to file
writer.write("\n"); //write a newline to the file
}
6. Close the writer.
7. Catch any exceptions if thrown

Key methods for reading, writing, serialization, and deserialization are also summarized.
File handling
The document discusses various components of C++ used for file handling such as header files, classes, file modes, and functions. It explains the classes ifstream, ofstream, and fstream used to open files in different modes. It also describes functions like open(), close(), get(), getline(), put(), tellg(), seekg(), tellp(), and seekp() and how to detect the end of files with and without using eof().
using System.docx
This document contains code examples of using streams in C# for reading and writing files. It demonstrates creating a FileStream and using StreamReader to read the contents of a file line by line. Another example shows using StreamWriter to write lines of text to a file. It also briefly explains the Stream, StreamReader, and StreamWriter classes and their uses for transferring bytes and reading/writing strings from streams.

Reflection in TypeScript: Wie wir die Schlucht zwischen Laufzeit und Compile-Zeit endlich überbrücken können
What's in a language? By Cheng Lou
What's in a language? How can it help us express our intent better? Based on his last talk, Cheng will explore some concrete, daily patterns in our codebase that Reason elegantly solves through a few simple yet rich concepts.
Chapter 10.1
The document discusses different types of files and the File class in Java. It explains that all files are collections of bytes to the computer, which are interpreted as text, numbers, images, etc. by software. Files can be categorized as text files containing ASCII characters or binary files containing other data types. The File class represents files and directories, and allows checking if a file exists, getting its length and name, and determining if it can be read or written. Methods like list() are used to get all files in a directory.
A rigid- well-insulated gas cylinder contains N0 moles of an ideal gas.docx
A rigid, well-insulated gas cylinder contains N0 moles of an ideal gas at a temperature To  and pressure Po. A venting valve is opened and the gas is pumped out of the tank. Derive an expression for the instantaneous temperature in the cylinder as a function of the number of moles of gas remaining in the cylinder. What is the final temperature Tf, if the tank is evacuated to Nf = 0? Is the prediction physically realistic? The heat  capacity at constant volume of the gas is independent of temperature.
Solution
PV = nRT
nT = PV/R = constant
nT = K
Tdn + ndT = 0
Tdn = - ndT
dT/dn = - T/n
dT/T = -dn/n
Integrating both sides
ln T = - ln n + C
at n=No ; T =To
so
ln To = - ln No + C
C = ln To + ln No = ln To*No
so
ln T = ln To*No - ln n
ln T = ln (To*No/n)
T = (To*No)/n
as n = Nf = 0
Twill tend to infinity...this is not practically possible

This is a java lab assignment. I have added the first part \"java retail class\" at the bottom. I am
unsure how to read the txt file into an array from the retail class. The stock txt file has been
added also.
A beginning framework and inventory list has been provided to you to use your Retail Item Class
as an array. Develop a program to accomplish the following menu items that can be selected by
the end user. Discussion of what each menu item should do is provided below the menu item.
Modify your object class file as desired. Please append initials to files created. Use Select-Case
for menu choices and methods to perform those choices. Please make a selection: 1. Open
Inventory File (This should ask the user for the file name, open the file and load the data into the
object array). 2. Display All (This should show a table of all items and data) 3. Display Reorder
Only (This should show only the stock number, Description and current quantity for items
requiring reorder) 4. Find Stock number (Allows the user to enter part of the description and
displays all matching stock numbers and descriptions matching that - case insensitive, such as
“cubs” or “cubs”) 5. Display Stock number (Allows user to enter stock number and displays
record of item) 6. Add Quantity (Asks for stock number and quantity for units, adds it to current,
displays record results) 7. Subtract Quantity (Asks for stock number and quantity, subtracts,
displays results including if reorder is needed.) 8. Change Price (Asks for stick number, changes
price to provided value, display results). 9. New Item (Allows adding a new item, updates count.
Display record results). 10. Save Inventory File (asks user for file name, save all inventory to
that file in a format that can be read back.)

In Java- Input is from a file- The input is all doubles- You are to in.pdf
The program reads in doubles from a file two at a time, uses those values to create Rectangle objects with a length and width, calculates the area of each rectangle, and outputs the rectangle with the largest area. It creates and initializes a Rectangle for the first input values as the largest so far, then loops to continue reading input and creating rectangles, comparing each new one to the current largest by area and updating the largest if a bigger one is found.

The problem is called Name Search and it has to be in C# 6. .pdf
The document describes a C# program that searches for names in two text files containing lists of the most popular boy and girl names from 2000-2009. The program loads the names into lists from the text files, then allows the user to search for a boy's name, girl's name, or both. It will display whether the searched names were among the most popular or not.
Python IO
File handling in Python allows storing and retrieving data from files. There are two types of data - persistent data stored permanently in files, and transient temporary data. Files can contain text or binary data. The os module allows creating, renaming, removing directories and listing their contents. Files can be opened in different modes like read, write, append to perform operations like writing, reading, copying and retrieving metadata. Objects can also be serialized into files and deserialized later for storage. The with statement automatically closes files after operations.

A Java class that allows writing to files is Class FileWriter. This class is a part of java.io package and extends (inherits from) OutputStreamWriter class.
This class allows us to write character files conveniently. The reason I chose this class is because of the functionality provided by FileWriter class. It allows us to write to a new file, as well as append content to an existing file. Given a filename as a string parameter, it creates the file if it does not already exist. So, the user is not required to explicitly create a new file before writing to it using FileWriter class.
FileWriter class provides several constructors, which are as follows:
1) FileWriter(File file) - takes File object as a parameter, which corresponds to the file, the data is to be written to.
2) FileWriter(File file, boolean append) - takes two parameters: one is the File object to which data is to be written to, and second is a boolean parameter which indicates whether data is to be appended to the file
3) FileWriter(String filename) - takes a string parameter for the filename
4) FileWriter(String filename, Boolean append) - takes two parameters, one for the filename (string) and a Boolean value indicating whether data should be appended to the file or not
Pseudo code:
1. Create a string array and initialize elements of the array with given data
String[] dataArray = new String[4];
dataArray[0] = "1001 Jennifer Ward SUPPLIES 2140.20 BOOKS 5200.10 PAPER 455.23 NORTH Phone";
dataArray[1] = "1003 Athena Andrews SUPPLIES 5155.55 BOOKS 6300.50 PAPER 223.25 SOUTH Email";
dataArray[2] = "1005 Andy Smith SUPPLIES 6155.55 BOOKS 300.50 PAPER 55.55 SOUTH Email";
dataArray[3] = "1006 Robert Stearns SUPPLIES 7255.55 BOOKS 8300.50 PAPER 77.77 SOUTH Phone";
2. Create a File object and pass the filename
File file = new File(“data.txt”);
3. Check if file exits by that name, if it does not create a new file as follows:
file.createNewFile();
4. Create FileWriter object by passing the File object created above
5. In a for loop write each element of the array to the file:
for(int i=0; i<dataArray.length; i++){
writer.write(dataArray[i]); //write the line to file
writer.write("\n"); //write a newline to the file
}
6. Close the writer.
7. Catch any exceptions if thrown

A rigid- well-insulated gas cylinder contains N0 moles of an ideal gas.docx
A rigid, well-insulated gas cylinder contains N0 moles of an ideal gas at a temperature To  and pressure Po. A venting valve is opened and the gas is pumped out of the tank. Derive an expression for the instantaneous temperature in the cylinder as a function of the number of moles of gas remaining in the cylinder. What is the final temperature Tf, if the tank is evacuated to Nf = 0? Is the prediction physically realistic? The heat  capacity at constant volume of the gas is independent of temperature.
Solution
PV = nRT
nT = PV/R = constant
nT = K
Tdn + ndT = 0
Tdn = - ndT
dT/dn = - T/n
dT/T = -dn/n
Integrating both sides
ln T = - ln n + C
at n=No ; T =To
so
ln To = - ln No + C
C = ln To + ln No = ln To*No
so
ln T = ln To*No - ln n
ln T = ln (To*No/n)
T = (To*No)/n
as n = Nf = 0

A simple camera telephoto lens consists of two How far behind the concave lens should the film be placed? Express your answer using two significant figures concave lens with a focal length f210.1 cm The object to be photographed is 4.01 m in front of the objective lens. cm Submit Part B What is the linear magnification of this lens combination? Express your answer using two significant figures.
Solution
The image from the first (convex) lens is formed at a distance i1 from the object
1/o1 + 1/i1 = 1/f1
1/401 + 1/i1 = 1/39
i1 = 43.2 cm
This image is formed 43.2 - 36.0 = 7.2 cm behind the second lens. That becomes the virtual image of the convex lens at i2 = -7.2 cm.
The object for that image is 1/o2 + 1/i2 = -1/f2
1/o2 - 1/7.2 = -1/10.1
o2 = 25.1 cm
o2 is actually the image of the lens system (interchange object and image in the concave lens formula).
Image i1 has magnification 43.2/401 = 0.108, and the image i2 has magnification 25.1/7.2 = 3.5. Overall magnification is 0.108*3.5 = 0.378

A priniciple purpose of a representation letter from management is to-.docx
A priniciple purpose of a representation letter from management is to:
Solution
Management representation is a letter issued by an auditor\'s client to the auditor in writing as one of audit evidences. The date of the document must not be later than the date of audit work completion. It is used to let the client\'s management declare in writing that the financial statements and other presentations to the auditor are sufficient and appropriate and without omission of material facts to the financial statements, to the best of the management\'s knowledge. it is a form letter written by a company\'s external auditors, which is signed by senior company management.
The letter states that all of the information submitted is accurate, and that all material information has been disclosed to the auditors. The auditors use this letter as part of their audit evidence. The letter also shifts some blame to management, if it turns out that some elements of the audited financial statements do not fairly represent the financial results, condition, or cash flows of the business.

Crystal clear water sports has 14-000 shares of $1 par value common st.docx
Crystal clear water sports has 14,000 shares of $1 par value common stock outstanding. Crystal Clear distributes a 10% stock dividend when the market value of its stock is $20 per share. Journalize Crystal Clear\'s declaration of the stock dividend on July 15 and distribution on July 31. What is the overall effect of the stock dividend on Crystal Clear\'s total assets? What is the overall effect on total stockholder\'s equity?
Solution
Date Account heads Debit Credit 15-Jul To record declaration of stock dividend Retained earnings (14000 * 10% = 1400 * $20) 28000 Stock dividend distributable (1400 * 1) 1400 Paid in Capital in excess of par (1400 * 19) 26600 31-Jul To record distribution of stock dividend Stock dividend distributable (1400 * 1) 1400 Common stock account 1400 2. Unlike cash dividend, stock dividend involves no distribution of assets or liabilities. So, it has no effect on the Assets or Liabilities 3. Stockholders\' equity, also called owners\' equity, is the surplus of a company\'s assets over its liabilities. Cash dividends reduce stockholders\' equity by distributing excess cash to shareholders. Stock dividends distribute additional shares to shareholders and do not affect the balance of stockholders\' equity. Net worth (Share capital + retained earnings) is not affected. It is an inter change of Numbers between the two. Equity capital balance is increased and retained earnings balance is reduced

Critical thinking question- what structural features (hint- there are.docx
Critical thinking question: what structural features (hint: there are four) do all ten of these opioid drugs have in common?
Opioids Opioids are a powerful class of alkaloids that act on the central nervous narcotic analgesics. All opioids presumably bind to the same mu-opioid receptor sites in the brain and spinal cord. The most prevalent naturally occurring isolated from the opium poppy-is morphine (named after Morpheus, the sod of dreams). A methoxy derivative of morphine that is also isolated from opium poppy is codeine, which is both less addictive and less effective as a reliever than morphine. By contrast, the diacetyl derivative of morphine (heroin) isanalgesic not only a more powerful as a narcotic but also more addictive than morphine Many other synthetic derivatives of morphine are opioid agonists that are used as narcotic analgesics (including oxycodone, oxymorphone, hyd system as a plant-derived nitrogenout bases that have pronounced physiologial acevity on humans the arcotic a drug dhas numbs the ngonisa molecule that combines antagonist a molecule that inhibits senses and induces stupor a druE hat with a receptor to initiate and meperidine), while others (such as methadone and buprenorphine) are used to treat opioid addiction.

Create a polynomial function that meets the following conditions- Expl.docx
Create a polynomial function that meets the following conditions. Explain how you created your polynomial.
4. Degree 3, 2 positive real zeros, 1 negative real zero, 0 complex zeros.
Polynomial:
Solution
Polynomial may be : f(x) = -x^3 + x^2 + x - 1 Reasoning : the number of positive roots of the polynomial is either equal to the number of sign differences between consecutive nonzero coefficients. so here has two sign change(the sequence of pairs of successive signs is -+, ++, +-). So it has 2 positive roots. for negative root we change the signs of the coefficients of the terms with odd exponents, i.e., apply Descartes\' rule of signs to the polynomial f(-x), to obtain a second polynomial f(-x) = x^3 + x^2 - x - 1 it has 1 sign change so f(-x) has one positive root so f(x) has 1 negative root.

Contrast the argument that terrorist acts are easy to predict with the.docx
Contrast the argument that terrorist acts are easy to predict with the argument that they cannot be identified or predicted. Write it 4-5 paragraph with resources(References).
Solution
By using technology it was easy to predict the terrorist acts. This is because terrorists use social media sites for communication and now-a-days there are many pattern recognization and data mining algorithms are implemented to identify the words and to predict the next action of the terrorists
reference:http://www.iflscience.com/technology/how-technology-help-predict-terrorist-attacks/
And even though advancement of technology cannot predict the terrorist act all the time, because if the terrorists are at one place then they don\'t use the internet or social media sites, so there will be no chance of prediction.
But NSA, which have access to almost every device in the world can easily predict the action of every human being in the world and there are many other security agencies like NSA also can do this thing. Majorly, technology plays an important role in identifying or predicting the action of terrorists

Constants Part A By measurement you determine that sound waves are spreading out equally in all directions from a point source and that the intensity is 2.7x10-2 W/m2 at a distance of 4.5 Im from the source What is the intensity at a distance of 3.5 m from the source? Express your answer using two significant figures W/m2 Submit Incorrect. Try Again; 6 attempts remaining Part B How much sound energy does the source emit in one hour if its power output remains constant? Express your answer using two significant figures Submit
Solution
Part A.
Intensity is given by:
I = P/A = P/(4*pi*r^2)
Since Source is same at both distance, So Power is constant, which means intensity is inversely proportional to square of distance from source.
I2/I1 = (r1/r2)^2
I2 = I1*(r1/r2)^2
I2 = 2.7*10^-2*(4.5/3.5)^2
I2 = 4.5*10^-2 W/m^2
Part B.
Power of source will be
P = I*4*pi*r^2
P = 2.7*10^-2*4*pi*4.5^2
P = 6.87 W
Now energy is given by:
E = Power*time
E = P*t
t = 1 hr = 3600 sec
E = 6.87*3600
E = 24732 J = 2.5*10^4 J
