Thread: Guessing Game Demo, wanting to add a doAgain Loop, but I don't know how to.

Ok, here's what I got.

import java.util.Scanner;

public class demoGuessGame {
 
    public static void main(String[] args) {
 
        Random any = new Random();
        Scanner input = new Scanner (System.in); 
 
        try {
 
        int maxNum, maxTries, guess;
        boolean win = false;
 
        maxNum = any.nextInt(10);
        maxTries = 0;   
 
 
        while (win == false)
        {
 
            System.out.print("\n" + "Pick a number between 1 and 10: ");
            guess = input.nextInt();
            maxTries++;
 
            if (guess == maxNum)
            {
 
                win = true;
 
            }
 
            else if (guess <= maxNum)
            {
 
                System.out.println("\n" + "The number you picked is TOO LOW.");
 
            }
 
            else if (guess >= maxNum)
            {
 
                System.out.println("\n" + "The number you picked is TOO HIGH.");
 
            }
 
        } 
 
            System.out.println("\n" + "YOU WIN!");
            System.out.println("The number was: " + maxNum);
            System.out.println("It took this many tries to get it right: " + maxTries);
 
        } // end of the try section
 
      catch(Exception msg)
      {
 
    	input.next();
    	System.out.println("\n" + "Sorry, invalid input- " + msg + " exception try again ");
 
      } //end of the catch section
 
    }  
}

I want to make it loop again when asked, "Do you want to play again?"

But I don't know how. Does anyone know how to?

No, not like that.

I meant for the program to loop again after you win.

Like this:

YOU WIN!
The number was: #
It took you this many tries to get it right:

Do you want to play again? Y/N?:

Do you know how to get it to work?

make a new boolean called "Again".(=true)
Then make a while before the program starts. ( While (Again = True)
after the program finishes you ask the scanner to do Y/N
Then when they say Yes make the boolean true
and when they say no make the boolean false!
Hope this helped!

Can you show me by using my code for an example?

I need to be sure so as I don't get all mixed up.

You can use my code to help you.

Sorry it's kinda hard and i don't want to rewrite the script etc etc. Good luck with the project! but now you know how to do it I suppose. Hope you can figure it out.

Start by reviewing this statement:

while (again = true)

Then consider that a boolean does not need to be checked for its equality to 'false' or 'true' in a conditional statement, because it IS false or true. With that in mind,

while ( again ), and

while ( !win )

are sufficient.
