public class MyClass {
    static void move_negative_to_end(int arr[]) {
        int size = arr.length;
 
        int j = 0;
        for (int i = 0; i < size; i++) {
            if (arr[i] > 0) {
                int tmp = arr[i];
                arr[i] = arr[j];
                arr[j] = tmp;
                j++;
            }
        }

    public static void main(String args[]) {
        int[] arr = { 0, 8, 0, 0, 0, 7, 15, 0, 0, 4, 6, 9 };  
 
        move_negative_to_end(arr);
  
        for (int i = 0; i < arr.length; i++)
            System.out.print(arr[i] + " ");
