Anthony Meyer from Flashline.com will speak on:

Interfaces & Abstract Classes

Have you ever wondered why you should use interfaces instead of abstract classes, or vice versa? Have you struggled with how to generalize your object without locking yourself into a rigid inheritance tree? Complete with UML Diagrams and code snippets, I will discuss the uses of interfaces as compared to abstract classes by taking the reader though an example that highlights the differences between the two.  If you have ever been confused on why both abstract classes and interfaces exist in Java, then attending this presentation is a must.
