What is the difference between polymorphism and duck typing?

Question

I\'m a little confused with the two terms, here\'s what I know:

Polymorphism is the ability of object of different types to be handled by a common interface. While d

Answer 1

Two type Polymorphism

1. Method overloading(Compile time Polymorphism ).
2. Method overriding(Run Time Polymorphism ).

Method overloading :- same function name and different data type is known as Method overloading

Example :

  int addTwovalues(int a, int b)
  { return (a+b)}

  float addTwovalues(float a, float b)
  { return (a+b)}

  Method overriding :- same function name and same data type but different Class
     is known as       Method overriding.


  class a
 {
  virtual int addtwovalues()
   {  // to do  }
  }
 class b:a
 {
     override int addtwovalues()
   {  // to do  }

  }



  a obj=new a();
  obj.addtwovalues();

  b objb=new a();
  objb.addtwovalues();  //run time Polymorphism
