Windows is a combination of C++, Assembly Language (Not fun), and I'm sure something others. What college's still teach PASCAL anyways and which companies are using the language? Also, who is using JAVA at their job and what are they using it for? Just curious because we use RPG IV, SQL, VB, COBOL, and a little C++. The web developement team uses the usual suspects for their projects.
Sorry - while this may have been true in 1996 things are much different now.
All more modern JVMs use JIT compiling. So, except for the first run through a code segment it is basically just as fast as C++.
The JVMs in browsers have not really changed since 1997, so people get a very skewed idea of the speed of Java. In an environment where you are running a server, you are (to the appearance of users) never ever having to interpret the language because all methods will usually run thousands or millions of times before the JVM is restarted. If you think of applets when you think Java, then you are thinking of Java from 5 years ago....
For a web project, there is no faster language than Java, period. For the resin servlet engine, JSP pages with light calculations are almost as fast as loading a static page and in many cases load many times faster than interpreted scripting languages like ASP, PERL, MOD_PERL and PHP. Same for network programming. Even C++ is slower for network programming because all C++ code is competing against native JVM code which is highly optimized with assembly code.
Even for straight up applications some JVMs are actually faster than VC++ and almost as fast as gnu C++ once the first run of methods is subtracted from the time, but these are expensive products that are basically designed for use in high end Java server environments.
To the guy who asked who does Java for a living and what they do with it:
I mostly do Java for a living, though I do a little bit of everything. I've used it for network programming and for large web projects, mostly, with online games and a myriad of other things thrown in. The biggest demand for it is in really high end websites and database-related projects. It is great on the high end because of EJB and EJB-like containers such as the one built in to Oracle which do some really amazing things automatically-basically everything but wipe your nose. Right now I am doing Java/Oracle for a medium-large intranet project to keep track of criminals that should last another year or maybe two.

Java has it's strength's, but it's not god's greatest gift to man as some would lead you to believe. It's the most god-awful inefficient language in the world, at the cost of being "easy" to program/maintain.
But my point is, by learning C first, you're forced learn how to do a lot of processes manually, and I personally think C will teach you to really "think like a programmer". That being done, you can master Object Oriented methodologies relatively easily.

Hey-don't knock it too much. The guy that invented pascal got a turing award for it.Quote:

Also, if you ever do database stuff, stored procedures are almost always done in pascal (sometimes Java) because it is great for DB access since it has lots of the stuff you would need for that built in. Also, Delphi is basically Pascal, and it is used a lot on HP-UX systems for 'mission-critical' DB applications.
Not as sexy as C++ or Java, but it's still a language worth knowing.
