I suppose if you like over-engineering

Over-engineering? You're confusing me with one of those guys that has to do a UML diagram before he can start coding.

I was mostly referring to the language. The standard library that comes with Java is over-engineered to the point of absurdity

Not _quite_ to the point of absurdity. I kinda like it. Admittedly, I dislike it when I have to instantiate four classes to read the contents of a file. But I have also used the same flexibility to great advantage, and been burned in other languages when the standard library wasn't flexible enough.

What languages are these? because I have never used a language where the standard library was not flexible enough.

If Java is good, then why isn't Scala better?
