Answer / shahir
Mainly there are four concepts for OOAD.
1.Abstraction -grouping of data and behaviour(operations)
into a conceptual object.
2.Encapsulation -Its the implementation mode of data
abstraction.With encapsulation, we can accomplish data
hiding
3.Polymorphism -Polymorphism refers to the process whereby
an object invokes a method of another object in a common
manner (with the same name) without understanding or caring
how it is accomplished.
4.Inheritance-When an object is derived from another
object. It inherits all the properties etc

Answer / prasi
Abstraction - Interfaces are the best examples of
abstraction .
Encapsulation - Classes are best examples of encapsulation.
Generally we encapsulate what varies &
we abstract commonalities...
One more thing, You should always subclass for behabiours..
you should never subclass for properties / attributes. If
only properties vary, then you have got to encapsulate them
in somewhere else e.g. in a class or in some collection
object like - Properties in Java / Map
Hope this helps..
