Overloading - Two functions having same name and return

Overriding - When a function of base class is re-defined in
the derived class.

Answer / janet

1. In overloading,there is a relation ship between methods
available in the same class where as in overridding,there
is relationship between a super class method and subclass
method.
2. overloading doesn't block inheritence from the
superclass where as overridding blocks inheritence.

3. in overloading,seperate methods share the same name
where as in overridding,subclass methods replaces the
superclass.

4.overloading must have different method signatures where
as overriding must have same signature.

Answer / shivanand

The main difference between overloading and overriding is
that in overloading we can use same function name with
different parameters for multiple times for different tasks
with on a class.
and overriding means we can use same name fiunction name
with same parameters of the base class in the derived class.
this is also called as reusability of code in the programme.

Answer / adeel shahid

overriding is done in the base class where the parent class
method is overridden by a method of the same signature.

Overloading is done in the same class on functions with
input parameters differing in number or type.

Answer / mansi shah

Overloading is evaluaated at compile time whereas
Overriding is evaluated at Run Time.

Overloading method has different Parameters but same name
whereas Overriding is just the implementation of method
define din Base Class.

Overloading does not interfere Base Class whereas
Overriding method must require the method which is declared
in Base Class.

Overloading can be defined in one class,in short term it
does not require separate Base Class to implement the
method,whereas for implementing method overriding the Base
class is necessary..
