I am generating an array of 6 ints within a range of 1- 54 (similar to lotto numbers). However, when trying to detect duplicates, my code is not executing. I tried to debug by simply printing "WE HAVE FOUND A DUPLICATE" if my conditional logic would catch a duplicate. Of course, it doesn't print the desired output:

```
18-33-39-41-41-45

```

I want to detect the duplicate so that I can generate another random number that is not equal to the discovered duplicate. I don't want to just increment/decrement the duplicate's value just to get another number, I want to actually generate another value between 1&54 that is not equal to the duplicate.

Here is my code:

```
public class Main {

    public static void main(String[] args) {

        Random rand = new Random();
        int[] luckyArray = new int[6];

        //build array
        for (int i = 0; i < luckyArray.length; i++) {

            int luckyNumber = rand.nextInt(54) + 1;
            luckyArray[i] = luckyNumber;
        }
        //detect duplicates in the array
        for (int i = 0; i < luckyArray.length; i++) {
            if (i > 0 && luckyArray[i] == luckyArray[i - 1]) {
                System.out.print("WE HAVE FOUND A DUPLICATE!");
                /* while (luckyArray[i - 1] == luckyArray[i]) {
                    luckyArray[i] = rand.nextInt(54) + 1;
                }*/
            }
        }
        //sort the array before printing
        Arrays.sort(luckyArray);
        for (int t = 0; t < luckyArray.length; t++) {

            if (t != 5) {
                System.out.print(luckyArray[t] + "-");
            } else System.out.print(luckyArray[t]);
        }
    }
}

```

I expected to compare the current index `[i]` to that of its previous `[i-1]` and if/when they are equal, produce a new value for the current index.

Thanks in advance!
