I have decided to play around with Google Web Toolkit (GWT) and Google AppEngine. Both look very interesting , very promising, and very fun. I don’t know very much about them, so this should be an interesting experience and I am sure to learn a ton of new technologies along the way.
My first app is just going to be a Task list. There are a plethora of Task Lists out there, but I think it will be fun and a good place to start. I’ve already created my site, The Super List, so feel free to watch the progress (if any)!

This is something that threw me off when I first encountered it; I should have read the tutorial.
“Primitive arguments, such as an int or a double, are passed into methods by value. This means that any changes to the values of the parameters exist only within the scope of the method. When the method returns, the parameters are gone and any changes to them are lost.”
“Reference data type parameters, such as objects, are also passed into methods by value. This means that when the method returns, the passed-in reference still references the same object as before. However, the values of the object’s fields can be changed in the method, if they have the proper access level.”
(reference: The Java Tutorial: Passing Information to a Method or Constructor)
