Java program to move all zero at the end of the array

Program to move zeros at the end of the array in java

public class MoveZeros {
  static void moveZeroElementToEnd(int[] arr) {
    // declare and initialize.
    int size = arr.length;
    int count = 0;

    // access all array elements.
    for (int i = 0; i < size; i++) {
      if (arr[i] != 0) {
        arr[count++] = arr[i];
      }
    }

    while (count < size)
      arr[count++] = 0;
  }

  public static void main(String[] args) {
    // take default elements in array.
    int[] arr = {
      5,
      1,
      6,
      0,
      0,
      3,
      9,
      0,
      6,
      7,
      8,
      12,
      10,
      0,
      2
    };
    moveZeroElementToEnd(arr);

    // print elements after moving 0's to end
    System.out.print("Array after moving zeros to end : ");

    for (int i = 0, size = arr.length; i < size; i++)
      System.out.print(arr[i] + " ");
  }
}

Output

    Array after moving zeros to end : 5 1 6 3 9 6 7 8 12 10 2 0 0 0 0
