数组重排序(如何将所有奇数都放在所有偶数前面)的深入分析

package Reorder;
public class Reorder {

 public static void main(String[] args) {
  int[] list = { 1, 2, 3, 4, 5, 7, 9, 11 };
  reorderOddEven(list);
 }
 public static void reorderOddEven(int[] list) {
  int length = list.length;
  for (int i = 0; i < length; i++) {
   System.out.print(list[i] + " ");
  }
  System.out.print("\n");
  int begin = 0;
  int end = length - 1;
  while (begin < end) {
   while (begin < end && (list[begin] & 0x1) != 0)
    begin++;
   while (begin < end && (list[end] & 0x1) == 0)
    end--;
   if (begin < end) {
    int temp = list[begin];
    list[begin] = list[end];
    list[end] = temp;
   }
  }
  for (int i = 0; i < length; i++) {
   System.out.print(list[i] + " ");
  }
 }
