package org.arpit.java2blog; import java.util.Scanner; public class NumberGuessingGameMain { public static void main(String args[]) { int attempt = 1; int guessedNumberByUser = 0; int expectedNumber = (int) (Math.random() * 99 + 1); Scanner userInput = new Scanner(System.in); System.out.println("Welcome to Number guessing Game \nYou Will Be Asked To Guess A Number To Win The Game \nYou have Maximum 5 Attemp Limit"); do { System.out.print("Enter a guess number between 1 to 100\n"); if(userInput.hasNextInt()) { guessedNumberByUser = userInput.nextInt(); if (guessedNumberByUser == expectedNumber) { System.out.println("Your Number is right. You Win the Game!"); break; } else if (guessedNumberByUser < expectedNumber) System.out.println("Your Guess Number is Smaller."); else if (guessedNumberByUser > expectedNumber) System.out.println("Your Guess Number is Greater."); if(attempt == 5) { System.out.println("You have exceeded the maximum attempt. Try Again"); break; } attempt++; }else { System.out.println("Guessed number is not valid integer"); break; } } while (guessedNumberByUser != expectedNumber); } } |
