Compare elements in an array for duplicates

Question

I am trying to generate a 5 digit int array in Java and am having trouble on where to start. None of the numbers in the array can be duplicates. I can generate

Answer 1

try this:

int[] digits = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 };
Random random = new Random();

int[] generateId() {
    int[] clone = digits.clone();
    int[] id = new int[5];

    for (int i = 0; i < 5; i++) {
        int candidate;

        do {
            candidate = random.nextInt(10);
        } while (clone[candidate] == -1);

        id[i] = clone[candidate];
        clone[candidate] = -1;
    }

    return id;
}

Answer 2

First off i want to thank all of you for helping out i really appreciate it.

I got this program to work the way i want but it seems like there should be an easier way though. Here is what i did. Any more comments would be awesome.

do
    {
        for (int i = 0; i < 5; i++) 
        {
            iNumber = generator.nextInt(9) + 1;
            numbers[i] = iNumber;
        }
    }
    while(numbers[0] == numbers[1] || numbers[0] == numbers[2] || numbers[0] == numbers[3] || numbers[0] == numbers[4] || numbers[1] == numbers[2] || numbers[1] == numbers[3] || numbers[1] == numbers[4] || numbers[2] == numbers[3] || numbers[2] == numbers[4] || numbers[3] == numbers[4]);
