In this episode we talk about the Decorator pattern and how it is applied. We cover a couple of caveats (especially when combined with the Observer pattern) and learn how to not be afraid of its verboseness. In all, it's the season of decorating, so let's decorate!

In this episode we go over Aspects (and AspectJ), what really is, and when to use them. It turns out, that there is nothing misterious about them! We also cover how to set-up Aspects for J2SE so you can start using them immediately!

In this episode we talk about Threads and Threading, the difference between Daemon and User Threads, and why changing priorities is not for the weak of heart. Also we cover Swing's golden Threading rule (with the Event Dispatching Thread). If you ever typed new Thread(), or if you heard to be careful about Swing and Threading, this episode is for you!

In this week's podcast we talk about Design Patterns (and the Grand Dads of the Software Patterns, the Gang-of-four), and dive into our first design pattern (of many), the Observer pattern. We discussed how to implemented (within Java), and went to describe its use in Java Swing, and why anonymous inner classes for Listeners doesn't create memory leaks (most of the time anyways). In all a great introduction to a first pattern (see what they are all about!)
