Simple java program converting Context Free Grammar to Chomsky Normal Form

I need a simple java program that can convert a Context Free Grammar into the Chomsky Normal Form. The program should be written in Java, and it should be relatively straightforward to create. This program should be able to generate the code for this conversion, ensuring that the grammar is in the Chomsky Normal Form. The program should get the input from the user on run-time using scanner. It should create a new start symbol, remove epsilon rules, unit productions and lengthy non-terminals (Basically should change the context free grammar according to the Chomsky Normal Form rules). This needs to be completed in another 5 hours. I am looking for someone who is an experienced programmer and is familiar with Java. If you are able to help me with this project, I would be deeply grateful. Thank you for your time and consideration.
