- Description: Create (Java Program) a phonebook directory that will store the contact numbers of N persons. Your program should allow the user to add, view, delete, and update the contacts in the phonebook. Note that one person can have multiple contact numbers. The program will stop when the user command is ‘X’. Program command and entry should not be case-sensitive. That means commands ‘I’ or ‘i’ and the name “Jacky” or “JACKY” are the same. Each contact number can be 7 digits or 11 digits only. The user should input a string containing the command, name, and contact number(s) (Limit the contact number of each person to three). This string should be broken down into fields in order to separate the different values and store them in their appropriate variables. Use linked list in the implementation. Your node must declare at least four instance variables. Program flow: Command> I Jacky 09211234567 Remarks: New contact has been added.

- Unix assignment Purpose: The purpose of this assignment is to use various concepts of the C Shell. 0. Change your default login shell to the C Shell. 1. Create a .cshrc file in your home directory that will do the following: * Create the alias (lsall) that will do all of the following: display the date, and a recursive long list of all files in a directory. * Create the alias (whoson) that will display the date and a sorted list of users logged in. * Declare the LOCAL variable that controls the size of your history list to the value 200. * Declare the shell variable that will cause the C Shell to send a message to your terminal whenever one of your background commands complete. 2. Create a .login file in your home directory to do the following. * Declare the GLOBAL Terminal Type variable to the value vt100. Display the value of the variable. Logout and log back in to make sure your .cshrc and .login files are automatically executed.

Summary In this lab, you use a counter-controlled while loop in a Java program provided for you. When completed, the program should print the numbers 0 through 10, along with their values multiplied by 2 and by 10. The data file contains the necessary variable declarations and some output statements. Instructions 1. Ensure the file named Multiply.java is open. 2. Write a counter-controlled while loop that uses the loop control variable to take on the values O through 10. Remember to initialize the loop control variable before the program enters the loop. 3. In the body of the loop, multiply the value of the loop control variable by 2 and by 10. Remember to change the value of the loop control variable in the body of the loop. 4. Execute the program by clicking Run. Record the output of this program.

Write a program that reads the name of a text file containing a list of photo file names. The program then reads the photo file names from the text file, replaces the "_photo.jpg" portion of the file names with "_info.txt", and outputs the modified file names. Assume the unchanged portion of the photo file names contains only letters and numbers, and the text file stores one photo file name per line. If the text file is empty, the program produces no output. Assume also the maximum number of characters of all file names is 100.arrow_forwardConsider the following code segment: done = False while not done : try : filename = input("Enter the file name: ") inFile = open (filename, "r") except IOError : print ("Error: File not found.") It is supposed to keep on prompting the user for file names until the user provides the name of a file that can be opened successfully. What line of code should be placed in the blank to achieve this goal? Select one: done = inFile done = True done = not inFile done = Falsearrow_forward
- Do the following program in Java Eclipse:A veterinarian services many pets and their owners. As new pets are added to the population of pets being serviced, their information is entered into a flat text file. Each month, the vet requests a listing of all pets sorted by their outstanding bill balance. You have to write a program to produce a report of animals and their owners sorted by theiroutstanding bill balances from the data in the flat text file. Below is a description of the information on the text file:• The first entry is the number of animals on the file (numeric)• The fields below repeat for each animal:o Owner name (String)o Birth year (numeric)o Bill balance (numeric)o Species (String)o Special feature (numeric or String)The animals serviced by the veterinarian are of four types: mammals, fish, birds, and reptiles.For a mammal, the special feature field on the flat file is the number of legs of the animal (numeric).For a fish, the special feature field is the type, bony,…arrow_forwardPython programming: Topic: Compresion - using functional function Write a program that prints the number of palindromes in this file ..../englishWords (tips , open file first then read the content before printing)arrow_forwardThis is the file :arrow_forward
