source projects Sun is involved in. Tomcat is developed in an open and
participatory environment and released under the Apache Software

developers from around the world.
Core Java Technologies Tech Tips offers useful information using
core Java technologies and APIs, such as those in Java 2 Platform,
Standard Edition (J2SE). Recent tech tips compared the performance
of ArrayList and LinkedList and offered some suggestions about which of
these classes is the right choice in a given situation. Another tech
tip explored the implementation of using Zero-Length Arrays for a data
filtering method as opposed to returning a null value.
In addition to supporting traditional Java applications, the
Java 2 Platform, Mobile Edition (J2ME) Personal Basis Profile
(PBP) also supports the Xlet application model. Eric Giguere's tech
tip "The Xlet Application Model" teaches you how to use the Xlet
application model.
Eric Giguere demonstrates how to store persistent user preferences in a
MIDlet (mobile applications based on the Mobile Information Device
Profile -- MIDP) as a single record rather than as several individual
records. These preferences can be anything from an email address to
information relating to recent uses of the application, such as which
screen was last displayed. His Tech Tip includes examples of code.
