这个怎么错了

   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");
		}    
	}
}
