Please answer, is polymorphism consist of both overloading & overriding or only overriding & how ?

Answer 1

overloading is compile time polymorphism and overriding is runtime polymorphism

Answer 2

POLYMORPHISM

POLY MEANS MANY

MORPHUS MEANS FORMS

POLYMORPHISM MEANS MANYFORMS

OR

SEEING THE SAME THING IN MANY WAYS IS CALLED POLYMORPHISM

THERE ARE TWO CONCEPTS

OVERLOADING

OVERRIDING

OVERLOADING : METHOD NAME IS SAME BUT

1 NO OF PARAMTERS

2 ORDER OF PARAMETERS

3 SIZE OF PARAMETERS

WILL BE DIFFERENT

EXAMPLE 1 (METHOD)

class Polygon
{
public void area(float r)
{
System.out.println(“Area = “ + Math.PI*r*r);
}
public void area(int s)
{
System.out.println(“Area = “ + s*s);
}
}
class Oltest
{
public static void main(String args[])
{
Polygon p=new Polygon();
p.area(2.25F);
p.area(10);
}
}

========================

EXAMPLE 2 (CONSTRUCTOR)

class Area
{
public Area(int l,int b)
{
System.out.println(“Area = “ + l*b);
}
public Area(int s)
{
System.out.println(“Area = “ + s*s);
}
}
class Contest
{
public static void main(String args[])
{
new Area(10,15);
new Area(10);
}
}

========================

OVERRIDING

METHOD IS SAME BUT IMPLEMENT IN ANOTHER CLASS

OVERRIDING IS REQUIRED IF CHILD CLASS IS NOT SATISTYING WITH THE DEFINITION GIVEN BY PARENT CLASS

SO CHILD WILL DEFINE ITS OWN CODE

THIS IS CALLED OVERRIDING

FOR OVERRIDING INHERITANCE IS NECESSARY

THATS WHY POLYMORPHISM WILL BE FULFILLED ONLY WITH INHERITANCE

EXAMPLE

class Square
{
public void calculate(int s)
{
System.out.println(“Square = “ + s*s);
}
}
class SqaureRoot extends Square
{
public void calculate(int s)
{
System.out.println(“Squareroot = “ + Math.sqrt(s));
}
}
class Ortest
{
public static void main(String args[])
{
Squareroot s= new Squareroot();
s.calculate(100);
}
}

Answer 3

Both are ways of achieving polymorphism... polymorphism means of many forms

Answer 4

Thanks for the info guys. 🙂

Answer 5

In Java, it is both.
The first one is the well known overloading while the other one is runtime polymorphism which is implemented using method overriding.
