[Bluej-discuss] exercise 4.24 Objects with Java Blue-J

[Luis Moreira]

Hi Marco,
This is the way I see it:
You get the lot's highest bid which is of type Bid, Bid has a bidder
which is of type Person, this Person as a name.

Lot.getHighestbid() .   getBidder()    . getName()
   Returns Bid         returns Person    returns Persons name

Hope it helps 
Regards
		Luis

Thankyou very much. The method works perfectly.

I am a little confused with the syntax of the method call:

lot.getHighestBid(). getBidder().getName().

Could you please explain or tell me where this is in the book.

Thanks again,
Marko
