现有3名选手排序输出所有选手的成绩怎么加？？？

import java.util.Scanner;

public class lianxi2 {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.println("----------------------------------------");
        System.out.println("*         宏图软件教育演讲与口才比赛评分系统       *");
        System.out.println("----------------------------------------");
        for (int ii = 0; ii < 3; ii++) {
            System.out.println("请为第"+(ii+1)+"位选手打分");
            int[] arr = new int[8];
            for (int i =0; i < arr.length; i++) {
                System.out.println("-------请输入第" + (i + 1) + "位裁判的打分：");
                arr[i] = sc.nextInt();
            }
            for (int i = 0; i < arr.length; i++) {
                for (int j = i+1; j < arr.length; j++) {
                    if (arr[i] > arr[j]) {
                        int temp = arr[j];
                        arr[j] = arr[i];
                        arr[i] = temp;
                    }
                }
            }
            System.out.println("选手得分由最低分到最高分排序为：");
            for (int i = 0; i < arr.length; i++) {
                System.out.print(arr[i] + "、 ");
            }
            int sum = 0;

            System.out.println("");
            for (int i = 0; i < arr.length; i++) {
                sum += arr[i];
            }
            System.out.println("选手平均得分为：" + (sum / 8));
        }

    }
}
