javase switch例子，以下是一个典型的switch语法运用的例子：

import java.util.Scanner;
public class JudgeMonth {
public static void main(String[] arg){
Scanner scan = new Scanner(System.in);
System.out.println(“请输入月份:”);
int month = scan.nextInt();
switch(month){
case 12:
case 1:
case 2:
System.out.println(“冬季”);
break;
case 3:
case 4:
case 5:
System.out.println(“春季”);
break;
case 6:
case 7:
case 8:
System.out.println(“夏季”);
break;
case 9:
case 10:
case 11:
System.out.println(“秋季”);
break;
default:
System.out.println(“没有这个月份！请重新输入.”);
}
}
}
