Encapsulation: Encapsulation is the mechanism that binds together code and the data it manipulates, and keeps both safe from outside interference and misuse. The wrapping up of data and methods into a single unit (called class) is known as encapsulation. The benefit of encapsulating is that it performs the task inside without making you worry. Polymorphism : Objects could be of any type. A discrete object can have discrete properties and methods which work separately to other objects. However a set of objects could be derived from a parent object and retain some properties of the parent class. This process is called polymorphism. An object could be morphed into several other objects retaining some of its behavior. Inheritance : The key process of deriving a new object by extending another object is called inheritance. When you inherit an object from another object, the subclass (which inherits) derives all the properties and methods of the superclass (which is inherited). A s...
