Scanner基本用法

public class Test2 {
    public static void main(String[] args) {
        // 键盘录入一个月份,用Scanner实现
        Scanner sc = new Scanner(System.in);

        // 接收数据
        System.out.println("请输入月份(1-12)：");
        int month = sc.nextInt();
switch(month) {
        case 1:
        case 2:
        case 12:
            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("你输入的月份有误");
                break;
        }
    }
}
