枚举可以有抽象方法吗?
问题描述：
枚举可以有抽象方法吗?如果有，有什么用，并给出一个场景来说明这种用法.
Can an enum have abstract methods? If so, what is the use, and give a scenario which will illustrate this usage.
答
是的，但您可能更喜欢实现接口的枚举，看这里.我觉得它看起来好多了.这是抽象方法的示例:
Yes, but you may prefer enum which implements an interface, Look here. I think It looks much better. This is example for abstract method:
public enum Animal {
CAT {
public String makeNoise() { return "MEOW!"; }
},
DOG {
public String makeNoise() { return "WOOF!"; }
};
public abstract String makeNoise();
}
