【程序34】

题目：输入3个数a,b,c，按大小顺序输出。

import java.util.Scanner;

public class lianxi34 {

    public static void main(String[] args) {

        Scanner s = new Scanner(System.in);

        System.out.println("请输入3个整数：");

        int a = s.nextInt();

        int b = s.nextInt();

        int c = s.nextInt();

        if(a < b) {

            int t = a;

            a = b;

            b = t;

        }

        if(a < c) {

            int t = a;

            a = c;

            c = t;

        }

        if(b < c) {

            int t = b;

            b = c;

            c = t;

        }

        System.out.println("从大到小的顺序输出:");

        System.out.println(a + " " + b + " " + c);

    }

}
