最有趣/有用的Java类？ [英] Most interesting/useful Java classes?

问题描述

我已经使用Java大约一年了，并且不断发现自己发现了该语言的新发现。有趣的是，大多数这些很酷的东西不是来自第三方API或库，而是来自JDK附带的类。

I've been using Java for a year or so now, and I constantly find myself discovering new things in the language. Most of this cool stuff, interestingly enough, doesn't come from 3rd-party APIs or libraries, but rather from the classes that ship in the JDK.

所以我我想知道，部分出于好奇和部分出于对他人和我本人的教育，JDK中的哪些类最有趣/最有用/最喜欢？

So I'm wondering, partly out of curiosity and partly for the education of others and myself, what classes that come in the JDK are the most interesting/useful/your favorite?
