Generics in the Java Programming Language

JDK 1.5 introduces several extensions to the Java programming language. One of these
is the introduction of generics.

This tutorial is aimed at introducing you to generics. You may be familiar with
similar constructs from other languages, most notably C++ templates. If so, you’ll soon
see that there are both similarities and important differences. If you are not familiar
with look-a-alike constructs from elsewhere, all the better; you can start afresh, without
unlearning any misconceptions.
