Here is a code of number game. We have modified it.

import java.util.Scanner;
import java.util.Random;
public class numberGame {
    public static void main (String[] args) {
        Random rand = new Random (); 
        Scanner keyboard = new Scanner(System.in);
        int x = (int)(100 * Math.random()) + 1;
        int userInt = 0;
        char userAns;
        int counter = 0;
        boolean guess = true;
        System.out.print("The Number guessing game, Would you like to play?: ");
        String userAns1 = keyboard.nextLine(); 
        userAns = userAns1.charAt(0);
        while (guess == true) {
            char userAns2 = 'y';
            if (userAns != userAns2) { 
                System.out.println("Goodbye!");
                guess = false;
            }
            else {
                System.out.println("\nI am thinking of a number between 1 and 100. Try to guess it.\n");

                while (x != userInt) {
