java怎么解答三个数以上的整数排序

Question

import java.util.Scanner;

public class Exercise8 {
private static Scanner input;

public static void main(String[] args) {
    input = new Scanner(System.in);
    System.out.print("Enter three numbers:");
    int num1 = input.nextInt();
    int num2 = input.nextInt();
    int num3 = input.nextInt();
    if (num1 > num2) {
        int temp = num1;
        num1 = num2;
        num2 = temp;
    }
    if (num2 > num3) {
        int temp = num2;
        num2 = num3;
        num3 = temp;
    }
    if (num1 > num2) {
        int temp = num1;
        num1 = num2;
        num2 = temp;
    }
    System.out.println("The sorted numbers are " + num1 + " " + num2 + " " + num3);
}

}
为什么debug时只运行第一个if，然后就直接跳到输出了

Answer 1

你的输入是多少？后面两个条件不满足自然不执行。
