给定一个由正数,负数和0组成的整数数组,将所有为0的元素,挪到数组末尾。要求时间复杂度O(n)

package comployeetest;
public class Test1 {
  public static void main(String[] args) {
    int[] arr = { 0, -2, 3,0,0,0, 4, 0, 1, 0, -1, 0, 3 };
    order(arr);
    for (int i : arr) {
      System.out.print(i + ",");
    }
  }
  public static void order(int[] arr) {
    int j = arr.length - 1;
    int i = 0;
    int temp;
    while (i < j) {
      if (arr[j] == 0) {
        j--;
        continue;
      }
      if (arr[i] == 0) {
        temp = arr[j];
        arr[j] = arr[i];
        arr[i] = temp;
        j--;
      }
      i++;
    }
  }
}
