Comment on Duplicate Reference: Why would this be marked duplicate when it was asked years prior to the question referenced as a duplicate? I also believe the question, detail, and response is much better than the referenced question.
I've been a C++ programmer for quite a while but I'm new to Java and new to Eclipse. I want to use the touch graph "Graph Layout" code to visualize some data I'm working with.
This code is organized like this:

How do I add this project in Eclipse and get it compiling and running quickly?
I think you'll have to import the project via the file->import wizard:
http://www.coderanch.com/t/419556/vc/Open-existing-project-Eclipse
It's not the last step, but it will start you on your way.
I also feel your pain - there is really no excuse for making it so difficult to do a simple thing like opening an existing project. I truly hope that the Eclipse designers focus on making the IDE simpler to use (tho I applaud their efforts at trying different approaches - but please, Eclipse designers, if you are listening, never complicate something simple).
This assumes Eclipse and an appropriate JDK are installed on your system
In the menu go to : - File - Import - as the filter select 'Existing Projects into Workspace' - click next - browse to the project directory at 'select root directory' - click on 'finish'
