What is method "Overloading" in object-oriented programming (OOP) ?

Method or function overloading allows a method with the same name to be declared more than once given that they have different input parameters.

For example, there is a method to calculate the area of shapes. There are different shapes such as circles and rectangles. In these two cases, if someone calls the function calculateArea, the result should be correct for the given shape, regardless of whether the shape is a circle or a rectangle. The declaration of this in a programming language in shown below:

Rectangle: calculateArea(double length, double width)

Circle: calculateArea(double radius)

A great advantage of method overloading is that it allows a programmer to use the function appropriately without having to know the inner-workings of that method.
