table generics. While the name might
throw you, generics actually bring a greater degree of type safety to Java
than anything you could imagine. It’s finally possible to create parameterized
types, lists that only accept
Strings, and ditch all that annoying

classes and methods accept, removing a huge amount of tedious errorchecking

Generics have a bearing on varargs, annotations, enumerations, collections, and even some of the new concurrency utilities of the language. While you may want to browse through other parts of this book, you’d do well to take your time and really work through this chapter, lab by lab. There, that’s enough introduction for a few chapters—let’s get to it.
One of Java’s greatest strengths is its typing. Everything is an ...
