Abstraction:
Hiding unnecessary things and showing the essential
information.
Example: Suppose take a car: In that we will have breaks
and stering and etc... Here when we are changing the gear
box to up or bottom then gears will work but we don't know
how they are managing internally and we don't no how it is
working. As a driver we don't need to know how it is
working internally when we are changing every time. That is
the reason they will hide the wires and cables internally
and they will show up only gear box to us.
Advantages: 1) Code will be clean and for managing it will
be very easy
Inheritance:
Acquiring the properties from super class to
subclass.
Example: Suppose take two java classes
Class A contains 2 variables and ClassB Extends Class A
that means here ClassB can access the classA variables
without declaring it. If we do this then the memory will be
less and reusable.
Advantages: 1)Reusability of code
Encapsulation: Wrapping up of data and methods into a
single unit.
Example: In our class we need to make all our varables and
methods keeping together.
Advantage: Maintance will be good
Polymorphism: It means many forms.
2 types:
1) Compile time polymorphism
2) Run time polymorphism
Method overloading is an example for Compile time
polymorphism and
Method overriding is an example for Run time polymorphism
