在eclipse中遇到求和，累加的sum最后总比正确结果少 1 ,能有人帮我解决这个问题吗？

问题遇到的现象和发生背景

问题相关代码，请勿粘贴截图

import java.util.Scanner;

public class text1 {

public static void main(String[] args) {
    // TODO Auto-generated method stub
    int [] scores  = new int [3];
    Scanner scanner = new Scanner(System.in);
    
    for(int i=0;i<scores.length;i++) {
        System.out.print("请输入第"+(i+1)+"个评委的打分:");
        scores[i] = scanner.nextInt();
    }
    scanner.close();

    int temp,sum = 0;
    for(int i = 0 ; i<scores.length; i++) {            
        sum += scores[i];              
        /*
        在 sum 求和的过程中  数据总是比正确答案少 1
        */
        for (int j = 0; j < scores.length-i-1; j++) {
            if(scores[j] < scores[j+1]) {
                temp = scores[j];
                scores[j] = scores[j+1];
                scores[j+1] = temp;
            }
        }
        
}
    System.out.println("总分是:"+sum);
    double result = (sum - scores[0] - scores[scores.length-1])*1.0 / (scores.length-2); 
    System.out.println("最高分:"+scores[0]);
    System.out.println("最低分:"+scores[scores.length-1]);
    System.out.println("平均分(去掉最高分、最低分):"+result);
}

}

运行结果及报错内容

请输入第1个评委的打分:2
请输入第2个评委的打分:3
请输入第3个评委的打分:4
总分数:8
最高分:4
最低分:2
平均分(去掉最高分、最低分):2.0

我的解答思路和尝试过的方法

我想要达到的结果

你的程序是这样错的，你看我的

```java
public static void main(String[] args) {
// TODO Auto-generated method stub
int [] scores = new int [3];
Scanner scanner = new Scanner(System.in);

    for(int i=0;i<scores.length;i++) {
        System.out.print("请输入第"+(i+1)+"个评委的打分:");
        scores[i] = scanner.nextInt();
    }
    scanner.close();
 
    int temp,sum = 0;
    for(int i = 0 ; i<scores.length; i++) {            
                    
        /*
        在 sum 求和的过程中  数据总是比正确答案少 1
        */
        for (int j = 0; j < scores.length-i-1; j++) {
            if(scores[j] < scores[j+1]) {
                temp = scores[j];
                scores[j] = scores[j+1];
                scores[j+1] = temp;
            }
        }
        sum += scores[i];  
        
}
    System.out.println("总分是:"+sum);
    double result = (sum - scores[0] - scores[scores.length-1])*1.0 / (scores.length-2); 
    System.out.println("最高分:"+scores[0]);
    System.out.println("最低分:"+scores[scores.length-1]);
    System.out.println("平均分(去掉最高分、最低分):"+result);
}

```程序

求和的代码单独计算，放在排序里面有问题，因为下面会交换数据，修改如下：

public class text1 {
public static void main(String[] args) {
    // TODO Auto-generated method stub
    int [] scores  = new int [3];
    Scanner scanner = new Scanner(System.in);
    
    for(int i=0;i<scores.length;i++) {
        System.out.print("请输入第"+(i+1)+"个评委的打分:");
        scores[i] = scanner.nextInt();
    }
    scanner.close();
 
    int temp,sum = 0;
    for(int i = 0 ; i<scores.length; i++)
      sum += scores[i]; 
    for(int i = 0 ; i<scores.length; i++) {            
        for (int j = 0; j < scores.length-i-1; j++) {
            if(scores[j] < scores[j+1]) {
                temp = scores[j];
                scores[j] = scores[j+1];
                scores[j+1] = temp;
            }
        }
        
    }
    System.out.println("总分是:"+sum);
    double result = (sum - scores[0] - scores[scores.length-1])*1.0 / (scores.length-2); 
    System.out.println("最高分:"+scores[0]);
    System.out.println("最低分:"+scores[scores.length-1]);
    System.out.println("平均分(去掉最高分、最低分):"+result);
}
}
