Answer 3

Stanford University uses Java in it's intro course "Programming Methodologies". They've added some libraries to it to make it less overhead code, but it IS Java and once the problems get complex enough, it is Object Oriented. Actually, IMO, it's a well balanced approach to OOP vs. procedural. Click on the Course link at http://see.stanford.edu
