Java Generics - Tutorial

Java Generics - Tutorial

ABSTRACT


In J2SE 5.0 the language as well as the platform libraries were extended to support and use generics types and methods.The use of generics in numerous core library packages (such as java.util , java.ref , java.reflect , etc.) affects almost every Java programmer, who uses Java 5.0. In this tutorial we discuss all language features related to generics, such as type parameters and wildcards along with their bounds, compilation issues such as type erasure and type inference, compatibility between generic and non-generic code, and many more. In particular, we take a look at programming idioms using reflection like supplying type information in form of `Class<T>` objects, sophisticated API design using wildcards as well as porting legacy code to Java 5.0.
