Give nihonglish.jj both the tokens ( uppercase and lowercase ) of the English words, and the grammar rules to parse Nihonglish. I have already already

Give nihonglish.jj both the tokens (uppercase and lowercase) of the English words, and the grammar rules to parse Nihonglish.
I have already already given you the following classes and interfaces:
Sentence.java,
Phrase.java,
SubjectPhrase.java,
ToPhrase.java,
You have to:
Define the terminals (they are called TOKENs in Javacc).
Define the grammar rules in Nihonglish.jj.
What this program does is restate the Nihonglish sentences into ordinary English:
$ javacc.sh Nihonglish.jj
Java Compiler Compiler Version 5.0(Parser Generator)
(type "javacc" with no arguments for help)
Reading from file Nihonglish.jj ...
File "TokenMgrError.java" is being rebuilt.
File "ParseException.java" is being rebuilt.
File "Token.java" is being rebuilt.
File "SimpleCharStream.java" is being rebuilt.
Parser generated successfully.
$ javac Nihonglish.java
$ java Nihonglish
Sentence to parse or "" to quit: I as for home to going.
I am going to home.
Sentence to parse or "" to quit: I as for home to going?
Am I going home?
Sentence to parse or "" to quit: Home to I as for going.
I am going to home.
Sentence to parse or "" to quit: Home to going.
I am going to home.
Sentence to parse or "" to quit: Store to going.
I am going to the store.
Sentence to parse or "" to quit: Store to you as for going.
You are going to the store.
Sentence to parse or "" to quit: You as for going?
Are you going?
Sentence to parse or "" to quit: You as for home to going.
You are going to home.
Sentence to parse or "" to quit: (I just pressed "Enter")
So let us go!
Nihonglish.jj:
