I just hate java.
The runtime has changes so many times, and is frequently not backwards
compatible. Very annoying to try and install some java stuff for
developers just to eventually find out that the library you need only
works with java 1.4, and you have 1.3, and there is nothing in the
library or documentation that tells you this. Java developers hardly
ever even consider this. They just use whatever version they have,
and assume everyone else has that too.
You should not need a class to store your main function. Programs require
some control logic. It should not all be objects. Something has to
manage your objects. What a stupid design.
Anytime you hit a website that is stupidly slow, you can be sure the
pages end in .jsp or something simular. Of course each page will jump
through 10 other pages on the way to where you are going, taking multiple
seconds per page.
So overall, the only impression one can get is that java is either a very
crappy language, or it attracts incredibly bad programmers, or maybe it
just makes people incredibly bad programmers.
OO can be a good tool. Making it the only tool in a language can never
go well, in in the case of java it certainly didn't go well.
The write once run everywhere, well that hasn't happened yet. So since
that doesn't work, please give us high performance native code instead,
rather than a stupid virtual machine that often doesn't let you reuse
code anyhow. It was a huge marketing push by sun and lots of managers
jumped on it, and it never delivered, and now we are stuck with all these
java programmers tying together hundreds of bloated java classes into
huge bloated slow applications.
I am not saying use python, or c or anything else. I am just saying
java isn't a solution.
