OVERLOADING is the process of declaring the methods having
the same name but diff signatures. Signature means diff
types & number of arguments.
OVERRIDING is the process of overwriting the methods of
base class in Derived Class.
Overriding is the example of run-time polymorphism and
Overloading is the example of compile-time polymorphism.
Overloading
1) Method can have different access specifier.
2) Method can have different return type
3) Method must have same name with different method
signatures.
4) It doesn't need inheritance as method should be in
same class.
Overriding->
1) Method must have same access specifier.
2) Method must have same return type.
3) Method must have same name with same method
signatures.
4) It needs inheritance and virtual keyword before it
declaration.
5) It requires non-static method.
