Explain encapsulation.
Encapsulation means that objects keep their state information private. Rather than directly manipulating an object's data, other objects send requests to the object, in the form of messages, some of which the object may respond to by altering its internal state.
Explain polymorphism.
This ability of different but related objects to respond, each in its own way, to identical messages is called polymorphism.
Explain inheritance.
Inheritance means that objects of one class can derive state and/or behavior from another (base or parent) class.
