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.
