Java: Please help with my code I am trying to get the following output and am not sure what I am doing wrong. Thanks.

Code:

import java.util.Random;

Tester:

import java.util.Scanner;

public class GuessingGameTester {

public static void main(String[] args) { System.out.println("Welcome to the Guessing Game");

Scanner keyboard = new Scanner(System.in); char guess = 'y'; while(guess != 'n' && guess != 'N')//while guess is not "no" { System.out.println("Enter maximum number: "); int max; max = keyboard.nextInt(); GuessingGame game = new GuessingGame(max); System.out.println("Enter number of guesses allowed: "); int allowedGuess = keyboard.nextInt(); game.newGame(allowedGuess);

while(game.isGameOver() == false) { System.out.println("Enter your guess, remember it must be between 0 and " + max); int guessNew = keyboard.nextInt(); System.out.println(game.guess(guessNew)); } System.out.println("Would you like to play again? Enter Y for yes, N for no."); guess = keyboard.next().charAt(0); guess = 'n'; keyboard.close(); } } }

Sample Output: Welcome to the Guessing Game Enter the maximum number 100 answer is: 8 (Included for testing only, should not be display in final program) Enter the number of guess allowed Enter your guess, remember it must be between 0 and 100 50 Too High Getting Warmer Enter your guess, remember it must be between 0 and 100 25 Too High Getting Warmer Enter your guess, remember it must be between 0 and 100 12 Too High Getting Warmer Enter your guess, remember it must be between 0 and 100 Too low Getting Warmer Enter your guess, remember it must be between 0 and 100 Congratulation Would you like to play again, enter Y for yes, N for no
