I disagree entirely, and I was a Java developer long before I learned
C#. I find the Java system incredible mind-bending and the only
difficulty I had transitioning to the .NET model of generics was
unlearning the Java model (which was a joy). There is nothing worse
than enforcing the use of .equals and friends over what should
effectively be primitive types, but are actually objects. And, of
course, there's the memory footprint you create by boxing primitives
for no good reason.
What you're specifying there, by the way, actually doesn't even make
sense since data like that would be better exposed in a property (or
getter method, if we're talking Java) since it's not something you
would expect to be able to set about all Mugs that exist in an
application all at once.
