Murach's Beginning Java 2, JDK 5
How to work with collections and generics

Once you know how to use arrays, this chapter shows you how to use collections, which are similar to arrays but provide more advanced features. Along with collections, you'll learn how to use generics, a new feature of Java 5.0 that lets you specify the type of objects that can be stored in a collection.
