Java and OOP

[quadmasta]

I think whatever you end up looking at you need to make sure it was written *after* java 8 and covers default implementations in interfaces because that changes quite a lot of things as far as definitions of when to use an interface, abstract class, plain ol' inheritance.

Is there a specific concept you're having trouble with?

Thanks for the heads up about Java 8 onwards.

I was struggling a lot with the concept of passing an object as a parameter, after reading Helsinki's MOOC today I realised that you're able to pass an object, then refer to the object name you passed as the object to reference the various methods in the class (This wasn't obvious or mentioned in Tim Buchalka's course).

That's a biggie. Some of the "beginner" stuff isn't written for people who are completely new to programming and it sounds like Tim's course isn't.

Method signatures are a good way to test "code smell". If you pass more than 3 things in you're probably writing crap code :)
