Method signature

A method signature is like an address label on a letter. It tells the computer where to find a certain method (or action) in the program. A method signature consists of the method's name, the number and type of parameters it needs, and the type of value it returns. For example, the method signature for a method that adds two numbers together might look like this: add (int x, int y) returns int. This tells us that the method is called 'add', it needs two integers as parameters, and it returns an integer.
