Answer / manoj jain
overriding and overloading both are type polymorphism.
overloading:-more then one functions or constructors have
same name but different signature is called overloading.
this is also called compile time polymorphism or static
polymorphism.
overriding:-method in child class has same name as in
parent class(function name and signature will be same in
parent and child class)that is called overriding.
child class method hides parent class method it is also
called bynamic binding or runtime polymprphism

Answer / muthusenthil
method overloading is to load some extra features in
existing method eg: a method takes string as an arguments
but overloaded method may take int along with String
trapPerson(String name)- pre-existing method
trapPerson(String name,int age)- overloaded method
(irrespective of return type)
this may take place in same class or derived clas
method overridding is to override a method from parentclass
to change its behaviour.name should be same as parentclass
method, behaviour may change
it should takes place between derived class
eg: class man extends superman
int walk() be one among characterstics of man overridden by
superman.

Overriding:: It's not any two classes will do to study this
scnario, because overriding will come in a scenario
involving parent child relationship.
public class Parent{
public void sum(int a, int b)
{
System.out.println(a+b);
}
class Child extends Parent
{
public void sum(int a, int b)
{
System.out.println("Sum of the integers = "+a+b);
}
}
}
class MainClass
{
public static void main(String[] args) {
}
}

Answer / zurreyab ahmad
Ovloding:in overloding case same method name and different
parameter and different return type
public class overlo {
public void add(int a, int b)
{
System.out.println(a+b);
}
public float add(float c, float d)
{
return c+d;
}
}
class main1
{
public static void main(String[] args) {
}
}
Overriding:: in overriding case the same method name and
same parameter and same return type and in overriding case
at least two class must have
public class overri {
public void add(int a, int b)
{
System.out.println(a+b);
}
class overri1
{
public void add(int a, int b)
{
System.out.println(a+b);
}
}}
class main1
{
public static void main(String[] args) {
}
}

Answer / senthamil kumaran
polymorphism can be divided into two tyes:-
Dynamic polymorphism or Run time polymorphism
Static polymorphism or Compile time polymorphism
Example for Static polymorphism
Method Overloading
Example for Dynamic polymorphism
Method Overriding
overloading: same method name but different argument list
is called as overloading
overriding:-same methodis redefined in the following
Derived classes with the same arugument list
