Move Zeroes

Given an array nums, write a function to move all 0's to the end of it while maintaining the relative order of the non-zero elements.

For example, given nums = [0, 1, 0, 3, 12], after calling your function, nums should be [1, 3, 12, 0, 0].

Note:

1. You must do this in-place without making a copy of the array.
2. Minimize the total number of operations.

public class Solution {
    public void moveZeroes(int[] nums) {
        int size = nums.length;
        int n = 0;
        for(int i=0;i<size;i++) {
            if(nums[i]!=0) {
                nums[n++] = nums[i];
            }
        }
        for(int i=n;i<size;i++) {
            nums[i] = 0;
        }
    }
}
