Overloading

Overloading occurs when several methods have the same names with different method signatures. In the example above, the same method speak can have 2 different forms or method signatures. The first one only includes a single parameter word, the second one includes 2 parameters: word and language.

Overloading lets two functions/method share a name if they differ in the number and or the type of arguments; two functions may not differ only in their return type
