Method overloading is a concept that allows the creation of several methods with the same name which differ from each other in terms of the type of the input and the type of the output of the function (for example, a square method, which takes a number and returns the square of that number). It is often necessary to create different functions for integer and floating point numbers. While overloading a method, we are really just making a number of different methods that happen to have the same name.
