In my assignment i have to make a simple version of Craps, for some reason the percentage assignments always produce 0 even when both variables are non 0, here is the code.

import java.util.Random;

Header, note the variables

public class Craps {
private int die1, die2,myRoll ,myBet,point,myWins,myLosses;
private double winPercent,lossPercent;
private Random r = new Random();

Just rolls two dies and produces their some.

public int roll(){
    die1 = r.nextInt(6)+1;
    die2 = r.nextInt(6)+1;
    return(die1 + die2);
}

The Play method, this just loops through the game.

public void play(){
    myRoll = roll();
    point = 0;

    if(myRoll == 2 ||myRoll == 3 || myRoll == 12){
        System.out.println("You lose!");
        myLosses++;
    }else if(myRoll == 7 || myRoll == 11){
        System.out.println("You win!");
        myWins++;
    }else{
        point = myRoll;
        do {
            myRoll = roll();
        }while(myRoll != 7 && myRoll != point);
        if(myRoll == point){
            System.out.println("You win!");
            myWins++;
        }else{
            System.out.println("You lose!");
            myLosses++;
        }
    }
}

This is where the bug is, this is the tester method.

public void tester(int howMany){
    int i = 0;
    while(i < howMany){
        play();
        i++;
    }

bug is right here in these assignments statements

    winPercent = myWins/i * 100;
    lossPercent = myLosses/i* 100;
    System.out.println("program ran "+i+" times "+winPercent+"% wins "+ lossPercent+"% losses with "+myWins+" wins and "+myLosses+" losses");



}

}
