问题描述

CoffeeSize {BIG,HUGE,OVERWHELMING}
CoffeeSize size;
CoffeeSize size;
}

class CoffeeTest {
public static void main(String [] args)
{
咖啡饮料=新咖啡();
drink.size = Coffee.CoffeeSize.BIG;
}
}

Coffee.CoffeeSize.BIG :我可以得到 CoffeeSize 只需使用类名称 Coffee 。我认为枚举类型是隐式静态的我是否正确?

解决方案

是的,是的。语言规范甚至这样说。从 JLS第8.9节(枚举)


class Coffee{
   enum CoffeeSize{BIG,HUGE,OVERWHELMING}
   CoffeeSize size;
  }

class CoffeeTest{
   public static void main(String[] args)
  {
       Coffee drink=new Coffee();
       drink.size=Coffee.CoffeeSize.BIG;
   }
}

Coffee.CoffeeSize.BIG: i can get CoffeeSize just using the class name Coffee. Am I correct when I think the enum type is implicitly static?

解决方案

Yes, it is. The language specification even says so. From the JLS section 8.9 (enums):
