simply hiding implementation details and show what ever the client programmer needs. there are two programmers in devolopint the project Class Creators (who create new datatypes) and client programmers (class consumers who use data types in their applications).
It is helpful to break up the playing field into class creaters and client programmers. The goal of the client programmer is to collect a toolbox full of classes to use for rapid application devolopment. The goal of the class creator is to build a class that exposes only whats necessary to the client programmers and keeps everything else hidden. why because the client programmers cant use it which means that the class creatior can change the hidden portion at will without worrying about the impact to anyone else. The hidden portion usually represents the tender insides of an object that could easily be corrupted by a careless or uninformed client programmer so hiding the implementation reduces program bugs.
