Implement the below pseudo-code in a Java program using a while loop and aswitch-case statement. The program should be well structured, and the taskperformed under each option (at least options 'b' to 'e') should be implementedas a separate method.NOTE: The Scanner class does not have a method to input a character. Inorder to read a character from the keyboard, use one of the following methods(after declaring the Scanner object):static Scanner kb = new Scanner(System.in);1. char ch = kb.nextLine().charAt(0); OR2. char ch = kb.nextLine().toLowerCase().charAt(0);where kb is a Scanner class object.The second method above also converts the input to lowercase, which is oftenuseful. Though these methods allow the user to input more than one characteron the input line, the rest of the line (after capturing the first character withcharAt(0)) is discarded.If you also want to ignore the leading spaces before the first character thenuse:1. char ch = kb.nextLine().trim().charAt(0); OR2. char ch =…
Change the Fraction class so that its instance variables (numerator and denominator) are hidden (i.e. private). Check that the client class (after this change) will now not compile. Why does it not compile? Provide the changes to the Fraction class and the TestFraction class such that the program can work with the private instance variables by implementing appropriate accessor and mutator methods. import java.util.Scanner;//test programpublic class testfraction{public static void main(String[] args) {//create a Scanner objectScanner in = new Scanner(System.in);//create new fractionFraction frac = new Fraction();//declare numerator and denominatorint n=1,d;System.out.print("Enter Fraction's Numerator: ");//input numeratorn = in.nextInt();System.out.print("Enter Fraction's Denominator: ");//input denominatord = in.nextInt();//loop execute until the numerator is negativewhile(n>=0){//call input with n and dfrac.input(n, d);//call displayfrac.display();System.out.print("Enter…
