UML class structure

The following UML diagram shows all the components of the Prototype design pattern:

Let's see these components as listed in following points:

• Prototype: The Prototype is an interface. It is uses the clone method to create instances of this interface type.

• ConcretePrototype: This is a concrete class of the Prototype interface to implement an operation to clone itself.

• Client: This is a caller class to create a new object of a Prototype interface by calling a clone method of the prototype interface.

Let's see a sample implementation of the prototype design pattern.
