Java中switch判断语句典型使用实例

下面一个是典型的switch语法运用的例子。

import java.util.Scanner; 
public class JudgeMonth { 
  public static void main(String[] arg){ 
    Scanner scan = new Scanner(System.in); 
    System.out.println("请输入月份:"); 
    int month = scan.nextInt(); 
    switch(month){ 
      case 12: 
      case 1: 
      case 2: 
        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("没有这个月份！请重新输入."); 
    } 
  } 
}
