Hey all you 1337zors
I have some pretty easy Java questions that I would like answered. I've never programmed in Java, and now I ahve a program due in it...in a 300 level course. Good times.
Basically, to get me started, I need to know how to write/run a Java program. I'm sure I can probably use notebook or something to write it but I don't have any software like VC++ for Java on my computer to run it, so what do I do to go about getting started?
Secondly, I have to use this Java to write an XML file. Which is just outputing a bunch of strings to either the command prompt, or in my case, a file stream. How do I open up a file stream in Java and output text to it? A sample of code that I could use the answers to the first question on would be great.
I think this should get me started, I might write back later with more questions if I choose to make the program more than barebones. I have a decent amount of experience with C and C++ so the concepts of programming are no problem, just syntax. I know I could use Google, but I've been up all night already on another assignment and am crashing for a bit. Having an answer when I wake up to work on would be great.
Thanks for the help in advance.

To get started go to http://www.javasoft.com and get the Java Development Kit (JDK) 1.5 (or another version if you need that...I think 1.5 has a lot of really cool new features to it). If you want a good IDE NetBeans is free and does a good job. Don't get the version where they bundle the JDK with it though. For XML stuff get JDOM (3rd party library, http://www.jdom.org)...it makes dealing with XML stuff very, very easy.

Well, I got JDK 1.5, looks alright, kinda figured some stuff out. But if I wanted to use the java executable to run a java class (lets call it Simple, and it has the public static void main(String args[]) statement inside of it, where do I put the file so that I can run
java Simple
and have it recognize the class??
