Java图文教程-38.switch结构

roger

新建一个类，类名叫XueXiSwitch

例：星期几判断

package com.xuenixiang.Shin;

 

import java.util.Scanner;

 

public class XueXiSwitch {

 

public static void main(String[] args) {

//星期几判断

System.out.println("请输入要判断的星期几对应的数字:");

Scanner s = new Scanner(System.in);

int xingqi =s.nextInt();

switch(xingqi) {

case 1:

System.out.println("星期一");

break;

case 2:

System.out.println("星期二");

break;

case 3:

System.out.println("星期三");

break;

case 4:

System.out.println("星期四");

break;

case 5:

System.out.println("星期五");

break;

case 6:

System.out.println("星期六");

break;

case 7:

System.out.println("星期天");

break;

default:

System.out.println("输入错误");

}

 

}

 

}

运行结果：
