I have a web application where the majority of my classes are not explicitly defined as being in a package so, if I understand things correctly, they live in the "default package". I have a smaller number of clases which I have split in to packages within the "default package". I'm now finding that I need to refer to some statically declared objects within the default package from within these sub-packages, and I'm also finding that I don't know how to do it! I guess I need to import the default package in to the relevant classes in the sub-packages but I don't know how to refer to it. Is there a special syntax to refer to the default package or am I faced with having to put all my classes in to a "real" package?
You've just hit the reason you should avoid the default package when developing "permanent" applications. You cannot import the default package. Also, the default package can't have sub-packages.
Our Dev teams are like yours. They’re continually cranking out code for new features/bugs fixes, testing, deploying, testing some more, responding to production monitoring events and more. It’s complex. So, we thought you’d like to see what’s working for us.

This tip assumes your component to be of rectangular shape and completely opaque.
Java contains several comparison operators (e.g., <, <=, >, >=, ==, !=) that allow you to compare primitive values. However, these operators cannot be used to compare the contents of objects.
