Static Binding and Dynamic Binding-2

Static Binding and Dynamic Binding-2

static binding 

When type of the object is determined at compiled time(by the compiler), it is known as static binding.

If there is any private, final or static method in a class, there is static binding.
Example of static binding

    class Dog{ 
     private void eat(){System.out.println("dog is eating...");} 
     
     public static void main(String args[]){ 
      Dog d1=new Dog(); 
      d1.eat(); 
     } 
    }

Dynamic binding

When type of the object is determined at run-time, it is known as dynamic binding.
Example of dynamic binding

    class Animal{ 
     void eat(){System.out.println("animal is eating...");} 
    } 
     
    class Dog extends Animal{ 
     void eat(){System.out.println("dog is eating...");} 
     
     public static void main(String args[]){ 
      Animal a=new Dog(); 
      a.eat(); 
     } 
    } 

Output:dog is eating...

In the above example object type cannot be determined by the compiler, because the instance of
Dog is also an instance of Animal.So compiler doesn't know its type, only its base type.
