java如何按顺序显示输入的分数？

Question

import java.util.Scanner;

public class Score {
    int num = 0;//students
    int score = 0;//score
    int[] arr = new int[num];

    public int student() {
        Scanner scan = new Scanner(System.in);
        System.out.println("Number of students");
        num = scan.nextInt();
        int[] arr = new int[num];
        for (int i = 0; i < num; i++) {
            arr[i] = scan.nextInt();
            score = arr[i];
            System.out.println(i + 1 + "students socre : " + score);
        }
        return score;
    }

    public void list() {
        int[] arr = new int[num];
        for (int i = 0; i < num; i++) {
            //arr[i]=score;
            System.out.println(+score);
        }
    }

    public static void main(String[] args) {
        Score a = new Score();
        a.student();
        a.list();
    }
}

如果我输入5名学生的分数为10、20、30、40、50， 所以我想展示一下

1 students socre : 10 2 students socre : 20 3 students socre : 30 4 students socre : 40 5 students socre : 50

and

10 20 30 40 50

但我的代码显示

1 students socre : 10 2 students socre : 20 3 students socre : 30 4 students socre : 40 5 students socre : 50

and

50 50 50 50 50
