Write an address book program that stores your contacts' names and their email addresses. The names and email addresses are originally stored in a file called phonebook.in, in the format: Harry Potter t..d@hogwarts.edu Hermione Granger b..h@hogwarts.edu Ron Weasley r..b@hogwarts.edu Draco Malfoy m..s@hogwarts.edu Severus Snape h..e@hogwarts.edu Albus Dumbledore a..x@hogwarts.edu Your program should read from the file, storing the names and corresponding email addresses in a dictionary as key-value pairs. Then, the program should display a menu that lets the user enter the numbers 1 through 5, each corresponding to a different menu item: 1) look up an email address 2) add a new name and email address 3) change an email address 4) delete a name and email address 5) save address book and exit When the user enters 1, the program should prompt them for a name, and then print the corresponding email address. If there is no dictionary entry under that name, the program should print, "Sorry,…
Unix-based operating systems usually include a tool named tail. It displays the last 10 lines of a file whose name is provided as a command line argument. Write a Java program that provides the same behavior i.e. the user can specify how many lines to print from the terminal. Display an appropriate error message if the file requested by the user does not exist, or if the command line argument is omitted.
Note: Make sure to display the last n lines of a file whose name is provided as a command line argument. You might need to pass a file as an argument, therefore make sure to have access to a sample file, the contents of which you want to print out.
The Committee for Fairness to File Descriptors is organizing a protest against the UNIX system
because whenever the latter returns a file descriptor, it always returns the lowest number not
currently in use. Consequently, higher-numbered file descriptors are hardly ever used. Their plan
is to return the lowest number not yet used by the program rather than the lowest number
currently not in use. They claim that it is trivial to implement, will not affect existing programs,
and is fairer. What do you think?

- Implement a system of three concurrent processes which read and write sequence numbers to a file. Each of the three processes must obtain 200 integers from the file. The file only holds one integer at a given time. Given a file, F, containing a single integer, each process must perform the following steps: Please show steps and answer.arrow_forwardWrite a Java program that will provide a count of the number of words, number of lines, and/or number of characters according to an option specified on command line along with the absolute path or relative path to the file upon which the program will operate. The following character combinations are to represent appropriate options:-w The option -w is used to provide a count of the number of wordsin a file and the file name. -l The option -l is used to provide a count of the number of lines in the file and the file name. -c The option -c is used to provide a count of the number characters in the file and the file name.If the path to the file is provided without any of the above options, then the file name and a count of the number words, lines, and characters is written to the standard output device. Solution must include at least one additional method whose purpose is to count the number of words, number of lines, and number of characters in the file.arrow_forwardSuppose I wrote a simple program to take in a filename from a user and then, using that given filename my program would execute a command to copy that file to a particular location (such as my own submission directory). I then made that program executable by someone else.

What would I need to do to ensure that nothing malicious was allowed to happen?arrow_forward
- When you compile and run packaged software from an IDE, the execution process can be as easy as clicking a run icon, as the IDE will maintain the classpath for you and will also let you know if anything is out of sorts. When you try to compile and interpret the code yourself from the command line, you will need to know exactly how to path your files. Let us start from c:\Code directory for this assignment. Consider a java file who's .class will result in the com.CITC1318.course package as follows: package com.CITC1318.course; public class GreetingsClass { public static void main(String[] args) { System.out.println("$ Greetings, CITC1318!"); } } This exercise will have you compiling and running the application with new classes created in a separate package: 1. Compile the program: c:\Code>javac -d . GreetingsClass.java 2. Run the program to ensure it is error-free: c:\Code>java -cp . com.CITC1318.course.GreetingsClass 3. Create three classes named Chapter1, Chapter2, and Chapter3…arrow_forwardA Command-Line Interpreter, or Shell Your shell should read the line from standard input (i.e., interactive mode) or a file (i.e., batch mode), parse the line with command and arguments, execute the command with arguments, and then prompt for more input (i.e., the shell prompt) when it has finished. 2. Batch Mode In batch mode, your shell is started by specifying a batch file on its command line. The batch file contains the list of commands that should be executed. In batch mode, you should not display a prompt, but you should echo each line you read from the batch file back to the user before executing it. You will need to use the fork()and not exec()family of system calls. You may not use the system() system call as it simply invokes the system’s /bin/bash shell to do all of the work. You may assume that arguments are separated by whitespace. You do not have to deal with special characters such as ', ", \, etc. However, you will need to handle the redirection operators…arrow_forwardA client sends you two files containing two shapes to be used in the design of a logo. Your computer could not recognize the format of the files sent in order to display them, so you manually open the files on a text editor, and found the following content within each file: File A File B (-2.5, -2) (0.5, 4) (2.5, 3) (-0.5, -3) START (-3, -2) <√34, 30.964°> <√10, 71.565°> <-5, -3> <-1, -3> Based on this data, name the types of the two shapes, justifying your answer by assessing the properties of each shape, and drawing a small sketch for each.arrow_forward
