J2ME in a Nutshell
Kim Topley
Publisher: O'Reilly
Edition March 2002
ISBN: 0-596-00253-X, 478 pages
J2ME in a Nutshell
provides a solid, no-nonsense reference to the 'alphabet soup' of micro
edition programming, covering the CLDC, CDC, KVM and MIDP APIs. The book also
includes tutorials for the CLDC, KVM, MIDP and MIDlets, MIDlet user interfaces,
networking and storage, and advice on programming small handhelds. Combined with
O'Reilly's classic quick reference to all the core micro-edition APIs, this is the one book that
will take you from curiosity to code with no frustrating frills in between.
