推荐答案

有免费的第一版PinS也讨论了这个主题。但是，我认为 best 的来源是本文由Odersky讨论Java中的平等。 PinS中的讨论是iirc，是本文的缩写。

There's a free 1st edition of PinS that discuss this subject just as well. However, I think the best source is this article by Odersky discussing equality in Java. The discussion in PinS is, iirc, an abbreviated version of this article.
