Episode 29. Scope (or how far away can you call), Inheritance, marker interfaces, and overrides! —- We go and visit the Primordial Java Concepts. As rules set in stone we explore the concept of multiple inheritance, method and variable scope (including the final keyword), abstract methods and @override. This is good for those starting up...

As developers, we have to deal with Exceptions every day (or at least every other day). In this episode we dive a bit on exception (and exception handling), plus we talk about certain behaviors that are not so well-understood (try returning from a finally block, or why exception stack traces sometimes misteriously disappears).

We have heard the word “Reflection” thrown around, what does it mean? it is a new Twilight series? is it about Vampires?

We finish our discussion on the ObjectOutputStream by covering the SerialVersionUID, and then move onto ObjectOutputStream’s citadine cousin, XMLEncoder and Decoder (and why would you go and hang out with it). We also make a quick introduction to “The Bean” (Java Beans that is), and...

We also cover the caveats of implementing the MVC, including escaped references in construction, and making the...

In this episode we talk about the Decorator pattern and how it is applied.
