Thread: Help with creating a Program class for a BASIC Interpreter in Java

I am current working on a Java Project that is due February 20, which is located here:

http://science.kennesaw.edu/~dgayler...s/project.html

Now, the professor provided me with several example classes for me to build upon. Now, I've already done the Lexical Analyzer, entitled JordansLexicalAnalyzer in the project, and JordansParser, JordansInterpreter, AssignmentOperator, ReservedWord, and a few modifications I've done to the example classes are what I've programmed in the zip file I have linked right here:

What I'm trying to do now is create this program class that the professor has suddenly brought up without notice on the feedback on my parser:

The trouble is, I don't even know how to create the program class. He said that I should use the grammar provided in the project to create the program class, but I don't know how I can interpret that in Java. I want to complete this before February 20, 2013, on 8:00 AM of that day. That's the due date. May you please help me with this project. I gave you a good bit of information to go by in order to help me out.
