[prog] Java Trees & Linked Lists

[ed orphan]

Could someone advise me on a good book
or two on programming double Linked Lists
and binary trees with Java?
I'm just learning Java now, but I need a
useful objective. You can't do much without
good data structures. Nothing that I'm 
interested in, anyway.
I suspect these books will be expensive.
Might there be some free tutorials on the
Web somewhere? ( I doubt it ).
I just hope there's a good book out there that
uses simple language and has lots of examples.
( fat chance ) 
Any advice would be welcome.
