OMG, Jave的JMenu居然有433个方法

OMG, Jave的JMenu居然有433个方法

Java的Swing类库中有一个类叫JMenu,这个类上面有7层的继承,加上所有被继承下来的方法,这个类一共有433个方法,虽然,很多类是从上面继承下来的,而它自己的方法并没有定义太多的方法,不过,继承体系过深,在底层类上要想知道所有的继承下来的东西并不是一样容易的事情。这个例子展示了一个滥用代码重用的反面案例。我个人认为我们应该反思一下滥用面向对象的作法。

要把Java一个类所有的方法例出来并不是一件难事,使用Javascript 利用Firefox浏览器所支持的Package来穷举JMenu的方法可以很方便的列出所有的方法。


下面是这段Javascripts程序:

 


虽然,在Firefox下有比较严格的安全限制,我们并不一定能够使用Swing类库中所有的Java方法,但我们查看一下其继承体系和一个类所拥有的方法却没有什么安全问题。

使用上面那段程序,你可以在Firefox中输出JMenu的433个如下的方法,下面是的列表中JMenu的方法在最后。

下面你可以理解为是在灌水:

OMG, Jave的JMenu居然有433个方法》的相关评论

  1. 版主?请问本文中JS调用Java的是什么技术?可以在html里面这么写嘛?偶尔看到这篇文章,对其中的这段内容有兴趣,还望告知,谢谢。

  2. java代码:Method[] methods = JMenu.class.getMethods;
    int i = 0;
    for(Method m: methods ){
    System.out.println(m.toString()+i);
    i++;
    }
