How do I write a random array of 5 integers but have it not count 0 as an integer?

I am trying to write a program that selects 5 integers at random between 1 and 6. I then need the program to display the missing integer. I can't figure out how to have it not display "0" as an integer. This is what I have so far...

import java.util.Random;

public class Task6
{
    public static void main(String[] args)
    {
        int[] numbers = new int[5];
        Random random = new Random();

        for(int n = 1; n < 5; n++)
        { 
            int select = random.nextInt(n + 1);     //shuffle generator so it will not duplicate numbers      
            numbers[n] = numbers[select];
            numbers[select] = n;
        }//end for statement
        for(int number : numbers)
        {
            System.out.println("Numbers selected : " + number);
        }//end for

    }
}

I have to have a O(n^2) operation in this as well.
