Hi guys..
I always to tend for get the 3 basic properties of OO...
Luckly I found an acronym to help me to remember the keywords.. it is PIE
P - Polymorphism
I - Inheritance
E - Encapsulattion
You should reverse PIE as IEP so that you get them properties according to importance i.e. Encapsulattion, Inheritance and Polymorphism...
Hope it helps other guys who are confused like me
