Introduction to OOP Chapter 15: Overloading : next previous audio real text

Overloading Based on Type Signatures

A different type of overloading allows multiple implementations in the same scope to be resolved using type signatures. 
class Example {
		// same name, three different methods
	int sum (int a) { return a; }
	int sum (int a, int b) { return a + b; }
	int sum (int a, int b, int c) { return a + b + c; }
}
A type signature is the combination of argument types and return type. By looking at the signature of a call, can tell which version is intended.
