Java opens quite a number of trapdoors despite of its alleged reputation as an "easy-to-learn" programming language. For the more ambitious and professional Java programmer it is essential to understand the subtleties of the language and to know what to expect of Java. This tutorial aims to shed some light on the more "interesting" areas of Java: it addresses pitfalls and helps avoiding common Java errors, plus it explains less commonly known, yet indispensable language features.

Specifically we take an in-depth look at the following concepts of the Java programming language:

Correct implementation of supposedly trivial infrastructure such a equals() and clone() is - to most people's very surprise - a non-trivial task. In this tutorial we see how to get it right.

Inner classes are an amazingly versatile language feature with a surprisingly cryptic syntax (in the case of anonymous inner classes). How do inner classes work and what are they for?

Weak references are designed to mitigate the problem of so-called "unwanted references", which are similar to memory leaks. How do weak references work
