java - 使用分支 if else 语句排序

Question

我在 1/3 上不断得到不正确的输出。当我输入 132 或 231 时，所需的输出是 123 我得到它。当我输入 321 时，输出是 132，我在这里错过了什么？

import java.util.Scanner;

public class Proj3 {
    private static int min;
    private static int max;
    private static int mid;

    public static void main (String[] args){
        Scanner keyboard = new Scanner( System.in);
        System.out.println("Enter three whole numbers <integers> to be sorted");
        int n1 = keyboard.nextInt();
        int n2 = keyboard.nextInt();
        int n3 = keyboard.nextInt();

        if (n1 <= n2 && n1 <= n3){
            min = n1;

            if (n2 <= n3){
                mid = n2;
                max = n3;
            } else{
                mid = n3;
                max = n2;
            }
        }
        else if(n2 <= n3){
            min = n3;
            mid = n1;
            max = n2;
        }else{
            min = n3;
            mid = n1;
            max = n2;
        }
        System.out.println("Here are the three numbers sorted:"+min+""+mid+""+max+"");
    }
}

您可以使用 Math.min 和 Math.max 来获取最小和最大数字(中间的数字是唯一的数字)，而不是分支 if左)
