Partial Solutions and Suggestions
Yeah, the problem is that one of your constructors doesn't initialize the final field. In Java final non-static fields have to be initialized at the declaration time, in an initialization block, OR in EVERY constructor! The default constructor in your example doesn't do that. Remember as well that implementing an empty default constructor makes sense only if you want to use inheritance features. If you don't provide a default constructor, but you will some other one Java won't make a hidden default constructor for you, because the default one is not required. So don't implement things like MyClass() {} with no special purpose - keep your code clean and save!
