reverse loop in java

public class Reverse {

  public static void main(String [] args){
    int i, j;

    System.out.print("Countdown
");

    int[] numIndex = new int[10]; // array with 10 elements.

    for (i = 0; i<10 ; i++) {  // from 0 to 9
      numIndex[i] = i;// element i = number of iterations (index 0=0, 1=1, ect.)
    }

    for (j=9; j>=0; j--){ // from 9 to 0
      System.out.println(numIndex[j]);//indexes should print in reverse order from here but it throws an exception?   
    } 

  }
}

Reverse Order Output for Java Do-While Loop

class DoWhile
{
    public static void main(String s[])
    {
        int n = 3;

        do
        {
            System.out.println("n = " + n);
            n--;
        } while ( n > 0 );

    }
