    Method overloading is a static polymorphism which can also be said as compile time polymorphism. It can be used when we identify the purpose is same but the type is different.

    Eg. If I want to perform addition of 2 numbers then first time I will consider 2 numbers are of type int but later I thought user may enter float or double values also then I will overload a method.

    In method overloading method name will remain same but parameters have to be different. Sequence of parameters also matters a lot.

    Return type doesn't matters it may be same or different according to the requirement.
