Dynamic Binding:

       1)  Dynamic binding is one of the distinct feature of Object Oriented Programming Concepts in java.
       2)  Dynamic binding always says “do not create an object of derived class “ but create an object of 
            base class.
            The advantage of dynamic binding concept is to give less memory space and higer performance.
       3)  Dynamic binding use always polymorphism related concepts.

Definition of Dynamic Binding
    
       The process of binding appropriate versions of derived class which are inherited from base class with base class object is known as Dynamic binding.
   While we are using dynamic binding at the time of executing polymorphism application jvm will internally considers the following two points
         a)      What type of object.
         b)      What type of address.

    In other words when we create an object indirectly jvm internally  considers above two points.
(Indirect object is nothng but dynamic binding).

OOPs Concepts With Real Time Examples

The Following Program illustrate the concept of Dynamic Binding

    Class BaseDemo
  {
      Void  fun1()
     {
      System.out.println(“this is fun1() of Base demo”);
      }
   }
  
   Class DerviedDemo1 extends BaseDemo
 {
     Void  fun1()
    {
      System.out.println(“this is fun1() of Derived demo1”);
     }
 }
   Class DerivedDemo2 extends BaseDemo
 {
     Void  fun1()
    {
     System.out.println(“this is fun1() of Derived demo2”);
    }
 }
  Class demo
 {
   Public static void main(String args[])
  {
     BaseDemo BD=new BaseDemo();
     BD.fun1();
     BaseDemo BD=new DerivedDemo1();
     BD.fun1();
     BaseDemo BD=new DerivedDemo2();
     BD.fun1();
   }
 }

Analysis:

From the above program Consider these things BD contains address of BaseDemo(), DerivedDemo1(), DerivedDemo2(). Hence BD is Polymorphic object.
The method fun1() is available in one form and it is redefined in multiple forms.Hence fun1() is known as polymorphic  method.
The statement BD.fun1() is actually one statement but is gives multiple results.Hence this statement is known as polymorphic statement.

Object Oriented Programming Principles Are :

1)      Class
2)      Object
3)      Data Abstraction
4)      Data Encapsulation
5)      Inheritance
6)      Polymorphism
7)      Dynamic Binding
