What is the difference between abstraction, encapsulation and data hiding?
Submitted by: venkat J Abstraction and encapsulation are two quite separate concepts in Java. Abstraction is a technique that is used to represent common functionality amongst a set of classes. An analogy is to look at a set of vehicles: Car, Truck and Bus have some common features that all road vehicles share. From a Java perspective, the mechanics of turning four wheels, an engine, could be handled in abstract form through a common super class. Abstraction allows subclasses to share common code without duplication.
