Java Generics was probably the most important feature added to the Java Language for Java 5.0. This book, written by one of the designers of generics, is a thorough explanation of how to use generics, and particularly, the effect this facility has on the way you use collections. Generics and collections allow for greater reuse of source code. While the benefits are great, it takes extra effort for developers to generify code. This book explains why the effort is well worth the gains and teaches Java developers how to use a generic library, how to write a generic library and specify collection types, and how to generify an existing library of legacy code. 'Java Generics and Collections' provides helpful hints and exercises that show the reader how to avoid the pitfalls of generics and speed up their Java development process.
