Dice Rolling Simulation

Question

I'm wondering how I could get my dice rolling simulator to stop when it your total roll is one of 2 certain numbers, (example: rolling will stop when you reach a total roll of 7 or 12). Here is my code so far:

public class RollDice {
 public static void main(String[] args) {
 // TODO Auto-generated method stub
 int dice1; // First Dice.
 int dice2; // Second Dice.
 int total; // Sum of the two rolls. 
 dice1 = (int)(Math.random()*6) + 1;
 dice2 = (int)(Math.random()*6) + 1;
 total = dice1 + dice2;
 System.out.println("Your first roll is " + dice1);
 System.out.println("Your second roll is " + dice2);
 System.out.println("Your complete roll is " + total);
 } 
} 

Answer 1

Just wrap everything with a do-while loop:

int total; // Sum of the two rolls. 
do {
 int dice1; // First Dice.
 int dice2; // Second Dice.
 dice1 = (int)(Math.random()*6) + 1;
 dice2 = (int)(Math.random()*6) + 1;
 total = dice1 + dice2;
 System.out.println("Your first roll is " + dice1);
 System.out.println("Your second roll is " + dice2);
 System.out.println("Your complete roll is " + total);
} while (total != 7 && total != 12);

Or something to that extent. :)

• hallibtch: For some reason it won't let me resolve total as a variable in the last line, why is this?
