# Prototype

Prototype is a creational design pattern that lets you copy existing objects without making your code dependent on their classes.

- declares a common interface for all objects that support cloning

    Circle(Circle source) {

        super(source);

        this.radius = source.radius;

    }

    

    //The method clone() creates an object of the current class and carries over all of the field values of the old object into the new one. 

    public Shape clone() {

        return new Circle(this);

    }

    

- Prototype registry implementation with HashMap

- when your code shouldn’t depend on the concrete classes of objects that you need to copy

- when you want to reduce the number of subclasses that only differ in the way they initialize their respective objects

Prototype:

- isn’t based on inheritance, so it doesn’t have its drawbacks

- requires a complicated initialization of the cloned object

Factory Method:

- is based on inheritance

- doesn’t require an initialization step
