Java and Immutability Explained

Duke WavingImmutability is a topic that has come up a lot at work in regard to threading. Since I really didn't understand what that meant in a programming context, I did what any aspiring developer should do. I wrote some code. So you can read my little write ups on the subject at the following links.

Java and Immutability Part I
Java and Immutability Part II

So what did I learn? That an immutable object is really just a read only object. But when it comes to reference variables, read only is a little tougher to achieve than one might think.

Source code is included. Please let me know if I screwed anything up. :)
