Restarting at the beginning of an array

[bonbon242]

Hi! I'm supposed to create a simple game that gains you points as the dice rolls and moves through the array. Basically, you enter an array. The dice is rolled, you move x amount of steps through the array. If you land on a 0, you lose. I'm having trouble figuring out how to restart at the beginning of the array once it moves through.

Here's what I have:

class A3Q2
{
    public static void main (String[] args)
    {
      int [] a;
      int dice;
      char x = 'y';
      int position = 0;
      int points = 0;
 
      System.out.println("Please enter an array.");
      a = ITI1120.readIntLine( );
 
      while (x == 'y')
      {
        dice = (int)(Math.random() * 5 + 1);
        System.out.println("The number of steps taken was " + dice + ".");
        position = position + dice;
 
        while (position > a.length)
        {
          position = position - a.length;
        }
 
        if (a[position] != 0)
        {
          points = points + a[position];
          System.out.println("You move in position  " + position + " and you gain " + a[position] + " point(s). Total points: " + points);
          System.out.println("Do you want to move again? (y/n)");
          x = ITI1120.readChar();
        }
        else
        {
          System.out.println("You move in position  " + position + " and you gain 0 points.");
          System.out.println("Sorry, you lost.");
          x = 'n';
        }
      }
    }
}

My attempt at this is the second loop in the code, which I thought would work, but it doesn't... help please!

Hi bonbon242,
I don't know if I understand your problem, but I think that if position is 4 and a.length()=3, you want return at the first element of your array.
For me, if you use mod function, you do it...
Try
while (position >=a.length){
position = (position % a.length);
}

in the place of your while loop.
Tell me something!
Bye!

Oh! Thanks so much that's exactly what I was looking for
