• Explanation:

1. public class DuckFactory implements AbstractDuckFactory {
   • This declares a public class named DuckFactory.
   • It implements the AbstractDuckFactory interface, indicating that instances of this class can create different types of ducks.
2. @Override public Quackable createMallardDuck() { return new MallardDuck(); }
   • This method is part of the AbstractDuckFactory interface implementation.
   • It creates and returns a new instance of MallardDuck, representing the creation of a Mallard duck.
3. @Override public Quackable createRedheadDuck() { return new RedheadDuck(); }
   • This method is part of the AbstractDuckFactory interface implementation.
   • It creates and returns a new instance of RedheadDuck, representing the creation of a Redhead duck.
4. @Override public Quackable createDuckCall() { return new DuckCall(); }
   • This method is part of the AbstractDuckFactory interface implementation.
   • It creates and returns a new instance of DuckCall, representing the creation of a Duck Call.
5. @Override public Quackable createRubberDuck() { return new RubberDuck(); }
   • This method is part of the AbstractDuckFactory interface implementation.
   • It creates and returns a new instance of RubberDuck, representing the creation of a Rubber duck.
6. }
   • Closes the DuckFactory class.

• Overall Explanation:
  • The DuckFactory class is an implementation of the AbstractDuckFactory interface.
  • It provides concrete implementations for creating different types of ducks (Mallard, Redhead, Duck Call, Rubber Duck).
  • Each creation method returns a new instance of the respective duck type.
  • This class is used to create ducks in the DuckSimulator and can be easily replaced with another factory that adheres to the same interface, allowing for flexibility in creating different types of ducks.
