switch例子

下面一个是典型的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.");
        }
    }
}
