源自：4-6 Java条件语句之 switch

这个用if怎么做？

char today='日';

   if((today.equals('一'))||(today.equals('三'))||(today.equals('五'))){

    System.out.println("早餐吃包子");   

}

        else if((today.equals('二'))||(today.equals('四'))||(today.equals('六'))){

         System.out.println("早餐吃油条");

        }else{

            System.out.println("吃主席套餐");

        }

    基本数据类型可以==来判断，引用类型用equals()

    char today='日';
   if((today.equals('一'))||(today.equals('三'))||(today.equals('五')))
      System.out.println("早餐吃包子");   
   if((today.equals('二'))||(today.equals('四'))||(today.equals('六')))
      System.out.println("早餐吃油条");
   if(today,equals('日'))
      System.out.println("吃主席套餐");
