java初级if语句编写程序

用java编写一个评分程序，接受评分为输出某选手的5个得分（0-10），然后去掉一个最高分和一个最低分，并输出去掉的最高分和最低分，求出最后的平均分（不用for循环）

public static void main(String[] args ) {
    Scanner sin = new Scanner(System.in);
    int a1,a2,a3,a4,a5;
    int max,min;
    double avg = 0;
    a1 = sin.nextInt();
    max = a1;
    min = a1;
    avg += a1;

    a2 = sin.nextInt();
    if(a2 > max)
        max = a2;
    if(a2 < min)
        min = a2;
    avg += a2;
    a3 = sin.nextInt();
    if(a3 > max)
        max = a3;
    if(a3 < min)
        min = a3;
    avg += a3;
    a4 = sin.nextInt();
    if(a4 > max)
        max = a4;
    if(a4 < min)
        min = a4;
    avg += a4;

    a5 = sin.nextInt();
    if(a5 > max)
        max = a5;
    if(a5 < min)
        min = a5;
    avg += a5;
    avg = (avg - max - min)/3;
    System.out.println("最高分="+max+",最低分="+min);
    System.out.println("平均分="+avg);
}

public class Test1 {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.println("开始打分[0-10]:");
        int score = 0;
        List<Integer> scores = new ArrayList<>();
        int i = 0;
        while (i < 5) {
            System.out.printf("第%s个分数：", i + 1);
            score = sc.nextInt();
            while (score < 1 || score > 10) {
                System.out.println("输入错误，请输入0-10范围内的数");
                score = sc.nextInt();
            }
            scores.add(score);
            i++;
        }
        sc.close();
        int sum = scores.stream().mapToInt(e -> e).sum();
        int max = scores.stream().reduce(Integer::max).get();
        int min = scores.stream().reduce(Integer::min).get();
        int result = sum - max - min;
        double aver = result / 5.0;
        System.out.println("最高分：" + max);
        System.out.println("最低分：" + min);
        System.out.println("最终得分：" + aver);
    }
}
