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.
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?
By definition, Object.
