newbie visibility question

Hello all
I have a class Fred.  A Fred object has a property a and a public boolean method b().
I also have a class Barney, which is very important to a lot of other classes.  Barney's main data object is an array of Fred objects:
public Fred[][] fredArray = new Fred[8][8];
Lots of other classes need to access this array of Fred objects.
One of them, class Wilma, wants to say something like:
boolean wilmaBool = fredArray[x][y].b()
What verbiage needs to be at the top of which classes to make this happen?
I mean, I probably need stuff like import or maybe package at the top of some/all of these classes, but I'm a bit lost as to what goes where.

Thanks for your help,

Edmund

 You do not have to import anything. Just put all the classes in the same package and then you can access them by simply declaring them - without importing them.

  Hope it helps.

Hi,
 You want to access that array in other classes then you have two options
 1. Make that array static and you can access like
   Barney.fredArray[x][y].b()
 2. have the Barney object and then access
   Barney barney;
   barney.fredArray[x][y].b()
 
 As mentioned by girionis if all the classes are there in  
 same package no need to import anything. if in other
 package then you have to import.

A vote of confidence in someone else's response is not an answer.
