I dislike Java a great deal these days.   It causes more problems than it used to solve.   Oracle really dropped the ball when it took over.   Many things that once worked are now broken.    The language as a LEARNING tool is still useful, but there are other object oriented languages so other than LEARNING I don't see java as particularly useful in an actually applied fashion.

I first started learning Java before the first VM that could run it was completed and out of alpha....  I saw some bizarre things.   Then it got good for awhile and dominated.   Then oracle acquired it, and it has been consistently downhill since then.
