Oops concept

Question

Oops concept

Accepted Answer

Object and class are base of oops.

Object is real world entity which has states or feachers and behaviour. These states are called fields of the object and they declare as a variable. Behaviour of a object is nothing but how it works. It means behaviour is function or method of the object.

Abstraction , Encapsulation , Inheritance and Polymorphism are oops theories.

Abstraction is a mechanism to display essential features instead of details. It is achieved by using access specifiers. Thoes are public, private, protected and internal.

Encapsulation is mechanism to combine states and behaviour in one unit. It is achieved by creating class.

Inheritance is mechanism to achieved the properties of another object and having own properties too. Class inherites another class is called derived class. A class which inherited is called base class.

Polymorphism means one object has many forms. It is achived by method overloading and method overriding.
