I have limited knowledge of Java, basically a book or two i've read on the subject, but never applied anything, but I will say, don't count your chickens before they hatch.
Any language and it's associated technology is difficult to learn, it takes time and patience. Otherwise the world would be full of professional Java developers which simply isn't the case.
Yes Java hideas alot from you, so making trivial apps like tetris (actually isn't that trivial) or calendars, etc, but when was the last time you saw anyone pay millions for a tetris game?
Java was designed to pick up the short falls of CPP and make enterprise development easier and more managable, it's why M$ jumped on with it's own version C# (very similar).
In no way does it make programming eaiser (per se) but rather simplifies mundane tasks that would otherwise slow you down or introduce trivial errors which are anything but trivial to track down.
If you've ever written a Windows application which was over 10,000 lines of C++ (not including the MFC libraries, etc) and sometime later discovered GDI leak or had it reported by a client that your software was crashing their computer and little else was known...in that case debugging becomes next to impossible and consumes many many many man hours to track down and first reproduce that error in your own envrinment.
Java and similar HLL's serve to circumvent these issues by hiding low level details like memory managament from you, so you can focus on application logic rather than ensuring your pointers are all freed, etc.
It's awesome you had a positive experience and gained some knowledge of the working environment, etc, but to claim it's "easy" is naive of you or anyone for that matter. It's not easy, it's jut different fthan previous development languages.
In trivial apps like Tetris or Tic-Tac-Toe, etc one can program a simple app using any language, whether it is done right given the working language is an entirely different story.
In anycase, have fun with it, but don't assume somethng is easy because you may soon become disheartened when something isn't easy.
Just my opinion of course
Cheers
