How can i remove the last "-" in the output?

Kevin Neuman :

    public static void main(String[] args) {
    int[] array = new int[6];

    for (int i = 0; i < array.length; i++) {
        array[i] = (int) (Math.random() * 90) + 1;
    }

    System.out.println("Dein Lottotipp lautet:");
    sort(array);
    printArray(array);
}

public static void sort(int[] array) {

    for (int i = 1; i < array.length; i++) {
        int sortieren = array[i];
        int j = i;
        while (j > 0 && array[j - 1] > sortieren) {
            array[j] = array[j - 1];
            j--;
        }
        array[j] = sortieren;

    }

}

public static void printArray(int[] array) {

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

        if (array[i] < array.length - 1) {
            System.out.print(array[i]);
        } else {
            System.out.print(array[i] + "-");
        }

    }
    System.out.println("");
}

How can i remove the last "-" in the output , im not the best java programmer; The output should be 27-28-37-73-75-81 ,but the output is this 27-28-37-73-75-81-., i need to remove the last - . Can someone please send me the edited code?

npinti :

To not print the last -, this line: if (array[i] < array.length - 1) { needs to become: if (i === array.length - 1).

At the moment, you are comparing the content of the array with the index you are currently processing. Comparing the content of the array won't do what you need, since you are only interesting in the current iteration number.
