用switch判断月份的练习

import java.util.Scanner;

public class SwitchTest01
{
    public static void main(String[] args) 
    {
        System.out.println("请输入月份");
        Scanner sc = new Scanner(System.in);
        int month = sc.nextInt();
        if (month >= 1 && month <= 12)
        {
            switch (month){
            case 3:
            case 4:
            case 5:
            System.out.println("春天");
            break;
            
            case 6:
            case 7:
            case 8:
            System.out.println("夏天");
            break;
            
            case 9:
            case 10:
            case 11:
            System.out.println("秋天");
            break;
            
            case 12:
            case 1:
            case 2:
            System.out.println("冬天");
            break;
            
            }
        }
        else
        {
            System.out.println("请输入正确的月份");
        }
    }
}
