- 17. Phone Book ArrayList Write a class named PhoneBookEntry that has fields for a person's name and phone number. The class should have a constructor and appropriate accessor and mutator methods. Then write a program that creates at least five PhoneBookEntry objects and stores them in an ArrayList. Use a loop to display the contents of each object in the ArrayList.Introduction In this project, you will complete a C++ class by writing a copy constructor, destructor, and assignment operator. Furthermore, you will write a tester class and a test program and use Valgrind to check that your program is free of memory leaks. Finally, you will submit your project files on GL. If you have submitted programs on GL using shared directories (instead of the submit command), then the submission steps should be familiar. In this project we develop an application which holds the information about a digital art piece. There are two classes in this project. • The Random class generates data. The implementation of this class is provided. It generates random int numbers for colors. To create an object of this class we need to specify min and max values for the constructor. The colors fall between 30 and 37 inclusively. The Art class generates random colors and stores the color values. You implement the Art class. An object of the Art class is a digital masterpiece.…Create a player class and a Key class. A Player hasa name, HP, and a key. A character may only have one key at a time, a Key contains a String array that lists the names of all the placed the key can go. The key should have a use() function that takes in a string of what it is trying to be used on, the function will return true if it can be used on that door, and false if it cannot. The player can pick Up and Drop a key.

A class is created called Maze, in which a 2D array for the maze is declared. Your job is to implement the constructor according to the given javaDoc. When you completed this task, write a set of Junit test case to test your code.As you probably noticed, the maze is defined as a private variable. The second job for you is to write an accessor(getter) method that returns the maze. Other information about what is expected for this method is given in the starter code. public class PE1 { MazedogMaze; /** * This method sets up the maze using the given input argument * @param maze is a maze that is used to construct the dogMaze */ publicvoidsetup(String[][]maze){ /* insert your code here to create the dogMaze * using the input argument. */ }DEBUG Exercise 1. // This file defines the Patient class used by// a doctor's office.

- Computer Science You are required to develop a small chatting application where two or more friends can communicate each other through messages. Create a class Message which has Date d, and message (string). Provide getters/setters, constructors, toString. Create a class Friend having String name, String contact, email and ArrayList of Messages provide getters/setters, constructors, toString addMessage(Message m) method which will add new message to the list. Provide following options to the user using JFrame. Login which will help user login to the application. View Friends (Display List of All Friends) View Messages ( This should display all message of a Friend) Send message (This should ask for friend name and message match the friend name and write that message to the array list).1) Create a "Car" class that keeps car ids and prices. And create a "Galleries" class that holds the car list for a particular gallery. In this class there should be methods for get / set and print for car name, car number and car list. Adding / Removing Cars to the List in This Class should have methods. And create another method to find and print the IDs of Cars with Car Segment equal to X. (print (X)). Car Prices are as follows according to the segments. 0-19999 -> Z20000-29999 -> Y30000-44999 -> T45000-100000 -> P Apply the Car list using "Single Linked List"(Node, newNode, head). The program should be written in JAVA.Observer pattern The PhoneModel class stores a phone number as a list of digits, and the Keypad class has this method: public void simulateKeyPresses(int numKeyPresses)(0 that allows the user to enter digits one at a time then save each digit in the list. The Screen wants to respond to each key being entered. Make the model notify the observers whenever a new digit is entered for the phone number. The first observer prints the newest digit out to the screen The second observer prints "Now dialing 12345678901.." out to the screen (where the number is the number the model has). Only the Screen class can print to the screen The model must be decoupled from the Other classes.
- Rectangle Object Monitoring Create a Rectangle class that can compute the total area of all the created rectangle objects using static fields (variables). Remember that a Rectangle has two attributes: Length and Width. Implement the class by creating a computer program that will ask the user about three rectangle dimensions. The program should be able to display the total area of the three rectangle objects. For this exercise, you are required to apply all OOP concepts that you learned in class. Sample output: Enter Length R1: 1 Enter Width R1: 1 Enter Length R2: 2 Enter Width R2: 2 Enter Length R3: 3 Enter Width R3: 3 The total area of the rectangles is 14.00 Note: All characters in boldface are user inputs.JAVA Include Code Comments create a public class named ArrayUtility In ArrayUtility class, create a public static method toString that receives an array of int's, a start string, a separator string and an end string. It returns a String starting with the start string, followed by the array elements separated by the separator and ending with the end string. create a public class named ArrayUtilityTest In ArrayUtilityTest class, create a public static method toStringTest that prints the results for the following 5 lengths of arrays, using different types of brackets and separators for each: empty, singleton, two elements, 5 elements and 20 elements. Call only this class in the main method and check the results. In ArrayUtility class, create a public static method equals that receives two arrays of int's and returns true if they have the same length and equal corresponding elements. In ArrayUtilityTest class, create a public static method equalsTest that prints the results for the…Assume that a class named Window has been defined. The Window class has a member function named clone that takes no arguments and returns a pointer to a new copy of the Window object. Also, assume that a class named GraphicProgram has been defined with the following members: executableName, a variable of the string type windowPtr, a variable of the Window* type Write a copy constructor for the GraphicProgram class that uses the clone function to make a proper copy of the Window object that windowPtr points to. The executableName member may be copied using simple assignment. Don't use GraphicProgram:: notation. Also put in c++ format
