如何制作一个带有默认注释的抽象类? [英] How to make a abstract class with default comments on it?

问题描述

我有一个带有抽象方法的超类，我想对该方法提供一些注释，如果有任何子类继承了该方法，则此注释将随之而来.

I have a superclass with an abstract method I want to provide some comments on the method and if any subclasses inherited this method this comments will come along with it.

class MySuper {

    //some comments
    protected abstract void myAbstractMethod();
}

class MyChild extends MySuper {

    //some comments
    @Override
    public void updateLanguage() {

    }
}

推荐答案

你需要添加适当的 java-doc 注释，这样实现类才会得到这些注释.

You need to add proper java-doc comments, than that implementing class will get those.

这个技术也用在 jdk 内部的不同地方——方法被继承只是为了获取它们的文档.

This technique is used in various places inside the jdk too - methods are inherited only to get their documentation.
