In this example, the full_factory_method_pattern has been implemented to solve this problem. Firstly, the CandyFactory class is now an abstract class, and there were two new classes ChocolateFactory and HardCandyFactory. Both of these classes extends the CandyFactory class. The CandyFactory class still has two methods, getCandy and getCandy package. The getCandy method is now an abstract method with no implementation. If I open the ChocolateFactory class, you can see that it provides a concrete implementation of this method. This version of the getCandy method is shorter because it only deals with candy in the chocolate section The HardCandyFactory class does the same. It implements the getCandy method so that he…
