Create class named billing that includes three overloaded computerBill() methods for a photo book store When computerBill() recieves a single parameter , it represents the price of one photo ordered .Add 8% tax, and return the total price when computerBill() recieves two parameters, they represent the price of a photo book and the quantity ordered .Multiply the two values, add 8% tax, and return the total price when computerBill() receives three parameters , they represent the price of a photo book, the quantity ordered, and a coupon value.Multiply the quantity and the price, reduce the results by the coupon value, and then add 8% tax and return the total value write the main() method that test all three overloaded methods.Save the application as Billing.java.
CSC: Rectangles Use JAVA program. Must. Create two classes. Class Rectangle is a class that represents an axis-aligned rectangle. Class RectangleTesteris the driver class, used to test the Rectangle class. Class Rectangle: An instance of the class Rectangle represents a valid axis-aligned rectangle. It has several instance variables that one needs to use to describe a rectangle, as well as methods that operate on these variables. Rectangle instance variables: Class Rectangle will have the following instance variables: •x –a double that represents the x coordinate of the lower left vertex of the rectangle •y –a double that represents the y coordinate of the lower left vertex of the rectangle •width –a double that represents the width of the rectangle •height–a double that represents the height of the rectangle •color –a String that represents the color of the rectangle •filled –a boolean variable that is true if the rectangle is filled, and false if it is not For the rectangle to be…
Purpose To review interfaces Directions Your task for this lab is to implement and test a class to store ratings of items. Your Rating class should have the following fields and methods: private double sumOfRatings - the sum of all of the ratings private int raters - the number of people who have rated an item public Rating () initialize both fields to zero public Rating (double sumofRatings, int raters) - initialize the fields to the parameter values public void addRating (double newRating) - increase the sumOfRatings by newRating and increase the number of raters by one public double getAverageRating () return the average rating; if there are no raters so far, return 0.0 public String toString() - display the average rating and how many reviews it is based on; for example, if the sum of the ratings is 32 and that is based on ratings from ten people, the toString method will return "3.2 based on 10 reviews"

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…
1. Create a .NET Class Library Maximum Implement three methods in it: a. the max method that finds a maximum among 2 integers, and displays their max b. the max method that finds a maximum among 3 integers, and displays their max c. the max method that finds a maximum in array of 10 integers and displays their max 2. Write a Console Application TestMaximum.cs that references Maximum Library. Implement the following: a. prompt the user to enter the number of integers they will provide, b. get the integers from the user c. call the Maximum library methods based on the number of integers. d. Call each of the implemented methods at least 1.
Design a class named CustomerRecord that holds a customer number, name, and address. Include separate methods to 'set' the value for each data field using the parameter being passed. Include separate methods to 'get' the value for each data field, i.e. "return" the field's value. Pseudocode:
Design and implement a class called Car that contains instance data that represents the company, price, model, and year of the car. Define the Car constructor to initialize these values. Include getter and setter methods for all instance data, and a toString method that returns a one-line description of the car. Create a driver class called CarTest, whose main method instantiates array of Car objects and write the following methods: 1) Method “printInfo” that receives an array of cars and returns all information about all cars. 2) A Method called getTopByCompany that receives an array of Cars and then returns an array of cars containing the cars that have the highest price compared with cars from the same company.
Exercise 1: Write a Java application that simulates a test. The test contains at least five questions about first three lectures of this course. Each question should be a multiple-choice question with 4 options. Design a Test class. Use programmer-defined methods to implement your solution. For example: create a method to simulate the questions – simulateQuestion create a method to check the answer – checkAnswer create a method to display a random message for the user – generateMessage create a method to interact with the user - inputAnswer Display the questions using methods of JOptionPane class. Use a loop to show all the questions. For each question: If the user finds the right answer, display a random congratulatory message (“Excellent!”,”Good!”,”Keep up the good work!”, or “Nice work!”). If the user responds incorrectly, display an appropriate message and the correct answer (“No. Please try again”, “Wrong. Try once more”, “Don't give up!”, “No. Keep trying..”). Use…
Course Title: Modern Programming Language Please Java Language Code Question : Create a Java Project With Your name as “MJibranAKramProjectQNo1”, add a class to this Project, Class name should be MJibranAkram with 18Arid2891 as “MJibranAkram18Arid2891” (a) Add a Method to Accept names and marks of n students from user, enter the value of n from User(b) Ensure that valid data is entered. If user enters an invalid data, then appropriate message should be displayed using Message Dialog Box e.g. ‘Name cannot be a number’ or ‘Marks must be an integer value’ (c) Add another Method, to Display this data in descending order according to marks such that name of student having maximum marks should come at the top and the name of student having minimum marks should come at the bottom.
