Java - 冒泡排序

 1 int[] arr = {84,65,85,659,595,59,25,1,5,84};
 2         for (int i=0;i<arr.length;i++){
 3             for (int j=0;j<arr.length-1-i;j++){
 4                 if (arr[j] > arr[j+1]){
 5                     int temp = arr[j];
 6                     arr[j] = arr[j+1];
 7                     arr[j+1] = temp;
 8                 }
 9             }
10         }
11         System.out.println("排序为:");
12         for (int value : arr){
13             System.out.print(value + " ");
14         }

定义一个新的临时变量temp暂存 arr [ j ] 。
