第三十八课.switch结构

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：
