refine/improve the UML design using Creational Pattern - Prototype and Structural Pattern - adapter in terms of TESTABILITY quality attribute. implement the refined design (Creational Pattern - Prototype and Structural Pattern - adapter) in java for comparison. (implement the classes of each of the refined uml diagram) Produce uml diagram after each refinement (Creational Pattern - Prototype and Structural Pattern - adapter)
