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

[Marko Bajic]

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
