Factory method is one of the Gang of Four's creational
. The purpose of the pattern is to define an interface for creating objects - but let the subclasses decide wich class to instantiate.
Take a look at
for some source code.
If you need more, then try to ask google - you'll get plenty of hits.

A JavaBean stores information.
A FactoryBean works with a JavaBean and contains the CRUD (create, read, update, and delete) methods and
The good part about FactoryBeans is that they keep your JavaBeans from being cluttered up with CRUD methods and JDBC code.
The bad part about FactoryBeans is that you have twice as many classes.
If you are not using separate FactoryBeans now, you probably have all the JDBC, and CRUD methods in your one JavaBean right now.
