Java Shift all zeros in array to end of array ?

• In Java we can shift all zeros in array to end/right of array using for loop.

public class shiftZeros {
    public static void main(String[] args) {
    int arr[] = { 0, 1, 0, 0, 6, 13, 0, 6, 0, 8, 5, 0, 2, 0, 4, 0, 5, -1, -4 };
    int temp;
    for (int i = 0; i < arr.length; i++) {
        for (int j = i + 1; j < arr.length; j++) {
            if (arr[i] == 0) {
                temp = arr[i];
                arr[i] = arr[j];
                arr[j] = temp;
            }
        }
    }
    for (int n : arr) {
        System.out.print(n + " ");
    }
  }
}

Output:
