The Prototype design pattern provides a solution:
Define a Prototype object that returns a copy of itself.
Create new objects by copying a Prototype object.
Describing the Prototype design in more detail is the theme of the following sections.
See Applicability section for all problems Prototype can solve.

• The key idea in this pattern is to create new objects by copying existing objects.
• Define Prototype objects:
  
  • To act as a prototype, an object must implement the Prototype interface (clone()) for copying itself.
  • For example, a Product1 object that implements the clone() operation can act as a prototype for creating Product1 objects.
• Create new objects by copying a Prototype object
  (Product product = prototype.clone()).
  
• This enables run-time flexibility (via object composition).
  A class can be configured with different Prototype objects, which are copied to create new objects, and even more, Prototype objects can be added and removed dynami­cally at run-time.
