BASIC CONCEPTS OF OOPS

OBJECTS

An entity that has state and behavior

Syntax: 'new' - a keyword to initialize an object in java

CLASSES

A group of objects which have common properties

Syntax: class Myclass{ //field; //method; }

ABSTRACTION

A process of hiding the details and showing functionality

Syntax: 'abstract' - keyword to declare an abstract class. Achieved by 'Interface' concept.

ENCAPSULATION

A process of wrapping code and data together into a single unit

Making all the data members of the class private, makes that class fully encapsulated .

INHERITANCE

A mechanism where one object acquires alla the properties of a parent object

Syntax: class Subclass-name extends Superclass-name{ //methods and fields } Achieved by 'interface'.

POLYMORPHISM

Can perform a single action in different ways

1.Compile-time Polymorphism: by method overloading. 2.Run-time Polymorphism: by method overriding.

DYNAMIC BINDING

The method call is bonded to the method body at runtime

Can be achieved by virtual functions.

MESSAGE COMMUNICATION

Set of objects communicate with each other

Create class that defines objects. Create objects from definition.
