内部类.目的是什么? [英] Inner Class. What is its purpose?

问题描述

有人可以告诉我开设内部类课程的目的是什么?我可以想到一些，但也许它们不是使用内部类的充分理由.我的理由是，当您要使用其他任何类都无法使用的类时，内部类会很有用.还有什么?

Can someone tell me what the purpose of having inner classes? I can think of a few but may be they are not good reasons for using inner classes. My reasoning is that inner class is helpful when you want to use a class that no other classes can use. What else?
