BETTER ENCAPSULATION THROUGH CAREFUL CODING

They key to good object-oriented programming (OOP) is constructing
viable objects. That's why object encapsulation problems are some of 
the more troublesome issues facing Java developers. Avoiding encapsulation
"gotchas" is on most coder's wish lists, but sidestepping these 
development land mines is easier said than done.

Objects should be totally self-contained to ensure that each code
element is modular and reusable, as well as secure and stable within its
current application. To achieve viable encapsulation, pay particular 
attention to these four mistake-prone areas:

* Getters and setters
* Immutability of return values
* Clone collections
* Return immutable iterators

See a discussion on these four "gotchas," and get a brief outline on how
to avoid the errors typically associated with them. Find out how to
ensure that your Java code is OOP-optimized and fully recyclable by
preventing object encapsulation deficiencies and related processing 
errors.
