public class HelloWorld {

    public static void main(String[] args) {

char today='日';

switch (today)

        case'一'：

        case'五':

        case'三':

        System.out.println("吃包子");

        case'二':

        case'四':

        case'六':

         System.out.println("吃油条");

        case'日':

        System.out.println("吃主席套餐"); 

}
