Additional Details

The thing is i dont know how to create a random generator code either.. and i dont really have the time to learn this in one night because its due in the morning.
Please i need your help!

 

This capability is built into the java.util library! Just import the library using:

Code:

import java.util.*;

Now you can create an instance of the Random class wherever you need it. Once you have your instance you can use one of several methods to generate a random number:

Code:

Random generator = new Random();
int randomIndex = generator.nextInt( nMaxReturnVal );

For more information just google "java random number generator" and you'll get many articles on the subject.
