Move Zeroes - LeetCode

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.

Input: [0,1,0,3,12]
Output: [1,3,12,0,0]

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

		while (index < nums.length) {
			nums[index] = 0;
			index++;
		}
	}
}
