Java入门小练习：输入月份求季节

package javastudy01;
import java.util.Scanner;
public class SwitchTest3 {
    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        System.out.println("请输入月份:");
        int month = scan.nextInt();
        switch (month / 3){
            case 1 :
                System.out.println("春天");
                break;
            case 2 :
                System.out.println("夏天");
                break;
            case 3 :
                System.out.println("秋天");
                break;
            default :
                System.out.println("冬天");
        }
    }
}
