老生常谈Scanner的基本用法

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;
    }
  }
}
