Say u have a banking application....
U have 2 transfer amount from one account 2 another...

U may have an

  
Class Account{
   
   public void withdraw(amount);
   public void deposit(amoount)
 
}
 
AND
 
class Transfer{
    public transfer(Account1,Account2);
}

Account is fine grained, while Transfer is Coarse grained.
U can use any one...
Infact "Transfer" can use "Account" internally.

My understanding of course vs. fine grained is:
Course grained refers to wrapping much or all of the data in a single method call and unwrapping for use at the destination; Fine grained refers to calling individual field accessors each time you require a piece of information.

Hope this helps.
