Just download and install the latest Java Developement Kit (JDK). It has all the necessary executables to compile and even decompile java code and executables.

Answer 2

If you want to get a more educated answer, try not using abbreviations. Most people won't know what you're talking about.

But if you want to compile and run Java programs (.java, .class, .jar), you should download JDK (Java Developer Kit).

Here is the download link: https://cds.sun.com/is-bin/INTERSHOP.enf...

Once you install it, you need to know how to use it.

-- How to compile --

Create a folder with your .java files, then make a .bat file (command prompt batch file) with this command:

"C:\Program Files\Java\jdk1.6.0_07\bin\javac.exe" *.java

This will create compiled (.class) files of your .java files. Change the location in the quotes to the location of your install folder.

-- How to run --

Once you have it all compiled, make a .bat file with this command:

"C:\Program Files\Java\jdk1.6.0_07\bin\java.exe" CLASS FILE YOU NEED TO RUN

There are other tutorials that go more in-depth. Google for it: http://www.google.com/search?q=compliing...

Good luck.
