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;    }  }}
