java - Array.sort 只返回 0 个值。数组大小正确并且数组已完全填充

Question

对这些线程中的另一个感到抱歉，但正在阅读那里的内容，但没有任何内容回答我的问题。我有一些非常基本的代码，只接受 5 个值，对它们进行排序，并对中间的 3 个值进行一些数学计算，最后输出一些内容。不难，但由于某种原因，我的 Array.sort 只返回值 0。我很确定数组中的所有点在排序之前都已填充，并且我的数组大小正确。建议？

import java.util.*;
import java.util.Arrays;

    public class practice {

        public static void main(String[] args) {
            // TODO Auto-generated method stub
            Scanner scanner = new Scanner(System.in);
            int[] finals = new int[3];
            int[] scores = new int[5];
            int difficulty = 0;
            for (int x = 0; x < 3; x++) {
                System.out.println("Please input the scores for diver " + (x + 1));

                for (int y = 0; y < 5; y++) {
                    scores[x] = scanner.nextInt();
                    System.out.println(scores[x]);
                }
                Arrays.sort(scores);
                for (int j = 0; j < 5; j++) {
                    System.out.println(scores[x]);
                }
                System.out.println("Please input the difficult of diver " + (x + 1));
                difficulty = scanner.nextInt();
                finals[x] = (((scores[1] * scores[2] * scores[3]) / 3) * difficulty);
                System.out.println(finals[x]);
            }
            winner(finals);

        }

        public static void winner(int[] finals) {
            System.out.println(finals[0]);
            if (finals[0] > finals[2] && finals[0] > finals[1]) {
                System.out.println("Diver 1 is the winner of the olympics with a score of " + finals[0]);
            } else if (finals[1] > finals[2] && finals[1] > finals[0]) {
                System.out.println("Diver 2 is the winner of the olympics with a score of " + finals[1]);
            } else if (finals[2] > finals[0] && finals[2] > finals[1]) {
                System.out.println("Diver 3 is the winner of the olympics with a score of " + finals[2]);
            } else {
                System.out.println("There was a tie");
            }
        }

    }

这个，

for (int y = 0; y < 5; y++) {
    scores[x] = scanner.nextInt();
    System.out.println(scores[x]);
}

应该是

for (int y = 0; y < scores.length; y++) {
    scores[y] = scanner.nextInt();
    System.out.println(scores[y]);
}

不要依赖硬编码长度。并记下您正在迭代的变量。。您在这里犯了一个非常类似的错误

for (int j = 0; j < 5; j++) {
    System.out.println(scores[x]);
}

应该是

for (int j = 0; j < scores.length; j++) {
    System.out.println(scores[j]);
}
