Answer / ankur dhoot
In overloading two function should have different signature
but overriding show have exactly same signature.
Overloading generally happens in same class but overriding
mandatory requires super and sub class to happen.
Compiler decides overloading at compile time but overriding
is detected at run time.
Overloading is called static polymorphism while overriding
is called dynamic polymorphism.

Overload :Deals single class bluebrint method selection
by using diffent proto type
(static buinding)
Overriding :Deals sub and super class bluebrints method
selection by using same proto type
(Dynamic buinding)

Answer / suganthi
Over Loading : when two or methods share the same name but
paramater declaration are diffierent with in a class.
(ex:Compile time polymorpism)
Over ridding: when two or methods share the same name but
paramater declaration are also same in different classes.
(ex:run time polymorpism)

Answer / raj kashyap
OVERLOADING is possible to create methods that have the same
name, but different parameters lists and different
definitions.overloading is used when objects are required to
perform similar task but using different parameters.
OVERRIDING is used when we want an object to respond to the
same method but have different behaviour when that method is
called. that means we override the method defined in super
class.yhis is possible by defining a method in subclass that
has same name,same argument& same return typeas method in
super class.

Answer / jitesh singh
OVERLOADING is done in the same class with different
singnature or parameter pass in the function
OVERRIDING is done in different class but the signature or
the parameter is same

Answer / praveen
Over riding also can be happens in the same class
eq :-
public void test(int i)
{
System.out.println(i);
}
public void test(String i)
{
System.out.println(i);
}
Over Loading - Compile time polymorphism
Over Riding - Run time polymorphism

Answer / ankit
IN overloading the function are used in same class, they
have different parameters each time we define the funtion,
and perform the same task.
overriding is used in diferent class with same parameters.

Answer / ghanshyam dobariya
OVERLOADING: Declaration and definition are in the same
class i.e. a class in which they are defined.
OVERRIDING:Declaration is done at super class while actual
definition is define in sub class.
OVERLOADING: Any code mistake we make in defining it's code
, detected at compile time
OVERRIDING: Any code mistake we make in defining it's code
,detected at run time.
