为什么静态方法在Java中不能是抽象的 [英] Why can't static methods be abstract in Java

问题描述

问题在于Java为什么我不能定义一个抽象的静态方法？例如

The question is in Java why can't I define an abstract static method? for example

abstract class foo {
    abstract void bar( ); // <-- this is ok
    abstract static void bar2(); //<-- this isn't why?
}

推荐答案

因为摘要是指： 实现无功能，静态意味着：即使您没有对象实例也有功能。这是一个合乎逻辑的矛盾。

Because "abstract" means: "Implements no functionality", and "static" means: "There is functionality even if you don't have an object instance". And that's a logical contradiction.
