OpenJDK mailing lists are about developing the software for the OpenJDK 
platform, not about how to write Java programs - hence no java-newbie 
lists. There are many such newbie resources elsewhere, which a simple 
google search will reveal. The answer to your specific question will 
also be in the Eclipse documentation - as it can execute the code you 
are creating. Java is a language that is executed by a virtual machine 
which initially interprets the bytecode of your Java program, and can 
also compile it to native code dynamically while running. The executable 
you run is the java launcher (eg java.exe), passing it the name of your 
main application class.

Cheers,
David
