Hi,

I was going through below link on the design patterns

http://npsakthivel.blogspot.com/2012/05/j2ee-po-bo-vo-dto-pojo-and-dao-concept.html


Based on my experience with these various design patterns and java programming most of it boils down to bunch of getters and setters. why java uses so heavily getters and setters. what is the mechanism and real purpose of these getters and setters.
which design pattern does not use getters and setters


VO ( Value Object )
The ViewObject performance layer object corresponds to the interface to display data objects. For a WEB page, or SWT, SWING interface, with a VO object corresponding to the value of the entire interface.


Is the VO is confined to performace layer only?

please advise
Any links resources ideas highly appreciated. Thanks in advance
