----------------------------------------------------------- From: aamirOnline Message 2 in Discussion Hi Abstraction : Abstraction refers to the act of representing essential features without including the background details or explanations.Classes use the concept of abstraction and are defined as a list of abstract attributes such as size,weight & cost,and functions to operate on these attributes.They encapsulates all the essentila properties of the object that are to be created. since the classes use the concept of data abstraction, they are known as <BLINK>ABSTRACT DATA TYPE(ADT)</BLINK>. Encapsulation : The wrapping up of data & function into a single unit (called class)is known as <BLINK>ENCAPSULATION. </BLINK>The data is not accessible to the outside world and only those function which are wrapped in the class can access it.These functions provide the interface between the object's data & the program. The insulation of the data from direct access by the program is called <BLINK>DATA HIDING </BLINK>. Thus in abstraction you create user defined data types (classes, structs etc...) , define its members (properties, fields, methods, events) and in Encapsulation you hide members which is not needed by outside the class regards m. aamir maniar senior software engineer - patni ----------------------------------------------------------- To stop getting this e-mail, or change how often it arrives, go to your E-mail Settings. http://groups.msn.com/mumbaiusergroup/_emailsettings.msnw Need help?
