Thread: Counting How Many Times Program Was Excecuted

Hey, I wanted to post this in a more specific topic area. What I'm creating in here is a program that will roll the dice upon the user's agreement, and ask them if they want to roll again. Everything works fine, but there's just one last problem. I need to add a counter in order to show how many times they played. (It would say "Roll 1: 3 4, Roll 2: 6 6, etc."

I thought using a for loop like this would work:

for (i = 1; i < number_of_plays; i++) would work, but I seemed to have put that in all kinds of different places in my code, and not one worked. The thing is, I had it working before, but when I started to change my loops around because my die weren't recalculating every time the user initated another play, it stopped advancing. Any suggestions?

Thanks.


Here's the code:

  package dicegamefinal;   import java.util.Scanner;   public class Main {   public static void main(String[] args) {   System.out.println("Welcome to Anthony's Die Roll application!");   int i = 1; int number_of_plays = i;         Scanner input = new Scanner(System.in); System.out.print("Do you want to roll the die? (1 = yes, 2 = no): "); int accept = input.nextInt();       while (accept == 1) {       if (accept == 1){ int die1 = (int)(Math.random() * 6); int die2 = (int)(Math.random() * 6);   if (die1 == 0 || die2 == 0) die1 = (die1 + 1); die2 = (die2 + 1);       System.out.println("Roll " + number_of_plays + ":" + " " + die1 + " " + die2);     if (die1 == 1 && die2 == 1){ System.out.println("Snake eyes!"); if (die1 == 6 && die2 == 6); System.out.println("Box cars!"); if (die1 == 2 && die2 == 5) System.out.println("Craps!"); }     else {     System.out.print("Do you want to roll again? (1 = yes, 2 = no): "); accept = input.nextInt();   }   } else System.exit(0);     }   while (accept != 1) { System.out.println("Thanks for playing!"); System.exit(0); } }   }

That was very helpful. I took what you said into consideration, and made a lot of changes. With the way you explained it, telling me it's wrong, why its wrong, and how to fix it, I also put a lot of new information into my stash for future programs. So this is what I have now. No errors (I hope!), and everything works. My last question is, I want to stick a "for" loop in there to count how many rolls the user has done. Right now, it's stuck on one.

I was thinking of using

 for (int number_of_plays; number_of_plays < 1000; number_of_plays++)

I stuck that right after the roll results, and before the prompt as to whether or not they want to continue, but it jumps from 1 to 1000 in one shot.

Any suggestions for this one?

Thanks again.
