Does anyone know how to set up the EasyIn.java class in netbeans IDE 6.9.1. If so please help!

ehm ...what exactly do you mean?
based on your description alone, my answer would be:

several possible ways to achieve this come to mind, but they all contain the very difficult and (almost) impossible to master technique of COPY - PASTE.

I'm pretty sure that, with just a little research, you'll be able to master this methodology of adding existing files to a netbeans project.

off course, if EasyIn is packed in a jar library, you could also import this jar file.
