- a) Design and implement a Comparable Java class to represent a Rational number such as3/2. Your class will have the following methods as well as any other methods necessary (setters, getters, etc.). - A constructor that takes all parameters (numerator, denominator), - A function that returns the number of existing Rational objects, - Override the tostring method, - Methods for adding and multiplying Rational objects, - Your methods will throw exceptions if there are problems. b) Write another class to test your Rational class including the exceptions.public class BackAccount{public double Balance { set; get; }public void Deposit(double amount){Balance = Balance + amount;} }Transaction FeesTransaction TypeDeposit Withdrawal Check BalanceAmount0.25 % of the deposit amount 0.5 % of the withdrawal amount FreeQ.1.1Amount0.25 % of the deposit amount 0.5 % of the withdrawal amount FreeQ.1.1Using the code snippet above, complete the bank account functionality by adding Withdraw and CheckBalance methods.

Complete the Course class by implementing the findStudentHighestGpa() method, which returns the Student object with the highest GPA in the course. Assume that no two students have the same highest GPA. Given classes: Class LabProgram contains the main method for testing the program. Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here.) Class Student represents a classroom student, which has three fields: first name, last name, and GPA. (Hint: getGPA() returns a student's GPA.) Note: For testing purposes, different student values will be used. Ex. For the following students: Henry Nguyen 3.5 Brenda Stern 2.0 Lynda Robison 3.2 Sonya King 3.9 the output is: Top student: Sonya King (GPA: 3.9) LabProgram.java import java.util.Scanner; public class LabProgram { public static void main(String args[]) { Scanner scnr = new Scanner(System.in); Course course = new Course(); int…
- For beginning Java, here is my assingment " 1. Define a Java class named “Appointment” that contains a day, a month and adescription of the appointment (string). It should provide at least a method named“hasTheSameDate” that will compare with another Appointment object andreturn true if it has the same date (day and month) and false otherwise. It shouldalso have the toString() method to return a string in the format of“mm/dd: description” such as “6/1: Meet with John”2. Write the main method to show how you can create Appointment objects, call thehasTheSameDate() method and print out the “Appointment” information: a. Ask the user for input for 2 appointment objects. b. Print the 2 objects. c. Call hasTheSameDate() to compare the 2 objects and tell the user if they are the same or different."Here is my code, and I don't know on what is wrong with my code: " import java.util.Scanner; class Appointment { private int day; private int month; private String…In this java assignment, we will be creating a paystub for an employee using classes, files, getters, and setters. Each file should only have one class and the class should share the same name as the file. We are going to implement the following classes: Employee - This class represent the employee. It needs the following fields exposed via getters and setters: Employee ID (hard code it to 1) First name, last name, middle initial Address, city, zip Phone, email Hourly rate PayPeriod - This class represents an employee's payment information. An employee will eventually have more than one pay period. It needs the following fields exposed via getters and setters: Pay period Id (hard code to 123456) Employee Id Start date, end date Number of hours PayrollManager - This class provides the functionality we need to compute and display the payroll. It should implement the following methods: double CalculateGrossPay (Employee, PayPeriod) - this should return the total gross for the…in java Define the class InvalidSideException, which inherits from the Exception class. Also define a Square class, which has one method variable -- an int describing the side length. The constructor of the Square class should take one argument, an int meant to initialize the side length; however, if the argument is not greater than 0, the constructor should throw an InvalidSideError. The Square class should also have a method getArea(), which returns the area of the square.Create a Driver class with a main method to test your classes. Your program should prompt the user to enter a value for the side length, and then create a Square object with that side length. If the side length is valid, the program should print the area of the square. Otherwise, it should catch the InvalidExceptionError, print "Side length must be greater than 0.", and terminate the program. screenshot shows output
