Why is Java taught in Universities?

It's opposite for me...I do things all day in work in C++ and then when I write Java I wonder why it didn't work. All this exception handling and events and listener crap confuses the hell out of me.
I'll admit it's an awesome language if I actually knew how to program in it instead of just hacking away at things...

java is a great language. It's too bad my class (which was supposodely a Data Structure class) taught me very little (the prof had no idea how to teach low level stuff, he was too smart for his own good) because i really wanted to learn teh language. From what i actually did learn though, it beats C/C++'s two seperate files for one program.
Java is in cell phones, new videogames, new software, there are even traces of java in C# (or so people say) and dont forget to mention that java is good for teh internet because of its cross platfrom compatibility.

Java may be a dream for programmers, but it's a nightmare for the admins who have to deal with the finnished Java programs.
Reminds me of a great quite, I don't remember where it's from.
"If Java had proper garbage collection, most programs would self-delete upon execution."
Since a C# is only "compiled" to MSIL (MS Intermediary Language, think "byte code" which is JIT compiled to native at runtime), it's technically cross-platform portable with the proper CLR (Common Language Runtime) for the platform you want to run on.
Currently there is a CLR which MS developed for Linux and MacOS X which is called "ROTOR". (I know it works on PPC and x86 hardware, don't know about SPARC.) I've seen it demoed in person but I've never actually used it. Apparantly since the C# languge is not propritetary (well I mean MS developed it, but it's an open standard), anyone could write a CLR for any platform that they needed to.
Needless to say, C# doesn't have nearly the platform diversity that Java does, at this point in it's life, at least.
Man that's a lot of acronyms in one post!

I don't have any qualms about JAVA as a language but to say it is ready to run as full fledged products is sily IMHO. We have TeamTrack at work and that is entirely JAVA and it's slow as beans. I mean have you ever seen a graphical JAVA program run fast? I haven't, even professional programmed products.
You can make DBVisualizer look pretty good.
Still runs like complete ass on pretty much any hardware though, as all Java apps do.

its for the development of quick products. specially when you need to churn out the product in a really short time period and optimization is not a big factor. it is used quite a lot commercially even though it is slow and a big memory hog.
I find GUI apps to be very slow, unless they're very small.
DBVisualizer is a good example, it's a complex piece of software, and extremely slow, maybe I was exaggerating a bit when I said "any hardware", replace that with "most hardware".
Sun's own SMC(Solaris Management Console) is another example.
It's dog slow on a 450 MHz US-II, I recon maybe it'll run halfway decently on a 1.3 GHz US-IIIi, but that shouldn't be required IMO.

because its the best and easiest language to learn OOP
also there are a lot of applications these days that use java
personally i use java in all the small programs I have to write there are prewritten classes fora bout everything you can dream of
also with the increase of memory on most computer these days you don't have to worry much about the "inefficiencies: of java for (memory use)
as someone said before if you don't understand why JAVA is great it means you should stay in college a bit more
