  再运行一下 ，default 后面最好加break 

  
  	public class HelloWorld {
  	    public static void main(String[] args) {
  	        char today='日';
  	        switch (today){
  	            case'一':
  	            case'三':
  	            case'五':
  	                System.out.println("吃包子");
  	                break;
  	            case'二':
  	            case'四':
  	            case'六':
  	                System.out.println("吃油条");
  	                break;
  	            default:
  	                System.out.println("吃主席套餐");
  	        }
  	    }
  	}
