10         for (int i = 0; i < numArr.length; i++) {
11             numArr[i] = numArr[i];
12         }
13         
14         for (int i = 0; i < numArr.length - 1; i++) {
15             for (int j = i + 1; j < numArr.length; j++) {
16                 if (numArr[i] < numArr[j]) {
17                     int temp = numArr[i];
18                     numArr[i] = numArr[j];
19                     numArr[j] = temp;
20                 }
21             }
22         }
23         
24         int sum = 0;
25         for (int i = 1; i < numArr.length - 1; i++) {
26             sum += numArr[i];
27         }
28         
29         System.out.println("去掉最高最低分后平均分为：" + sum * 1.0 / (numArr.length - 2));
30         
31         
32     }
33 
34 }

 

结果如下：

去掉最高最低分后平均分为：94.25
