What is the name of......

Hey,

First I will describe what I am trying to do.

I am a a java 2406 class at a Community College. and my prof seems to be clueless or just lazy probably the later. But I asked him how to add my own library(I believe this is what its called, similar to javax.swing.*. he didnt know how to do this and I am looking for the name of this specific file type I guess you could call it.

It would be something I imported like javax.swing.* except I want to create it myself but I need to know the name of this specific file type so I can do some research and find out how to do it. So if I could get name of what this would be called that'd be great or a link to a tutorial, I use Eclipse:Helios as my IDE.

JAR (Java Archive) usually contain libraries, a collection of class files. More IDE's will make a jar when you build. Just add the JAR to your project path, and import.

Thank you.
