Classes, Instances & Constructors

A class definition is like a sewing pattern that provides the instructions for constructing a garment. When you use a class, you instantiate it (create an instance) by using the new keyword with something that looks like a method call. It looks like a method call because it is a method call, a call to a special kind of method called a CONSTRUCTOR.

Constructors are just a kind of method, and are created like them. But there are a few additional rules:

• Constructors must always have the name of the class itself.

• Constructors don’t specify a return type. (They always return an instance of the class.)
