Abstract classes and interfaces can both be used to specify common behavior of objects. How do you decide whether to use an interface or an abstract class? Explain your answer.

Make sure you know the difference between an abstract class and an interface and constructors.

B elow for each class you find a UML and description of the public interface. Implementing the public interface as described is madatory. There's freedom on how to implement these classes.The private properties and private methods are under your control.. There are multiple ways of implementing all these classes. Feel free to add private properties and methods. For each object, it's mandatory to create a header file (.h), implementation file (.cpp) and a driver. Blank files are included. The header should have the class definition in it. The implementation file should contain the implementations of the methods laid out in the header fine. And finally the Driver should test/demonstrate all the features of the class. It's best to develop the driver as the class is being written. Check each section to see if there are added additional requirements for the driver. Two test suites are included so that work can be checked.  It's important to implement the drivers to test and demonstrate…

Explore scenarios where you might need to implement a custom Comparator for a class that already implements the Comparable interface. Provide real-world examples for context.

Both abstract classes and interfaces may be used to specify the behavior of common objects.Which factors should you examine when deciding between an interface and an abstract class?

In order to qualify as a subclass of an abstract class, a class must offer concrete implementations for all of the abstract methods defined in the abstract parent class. Exactly how do you feel about this?

A subclass of an abstract class must provide concrete implementations for each of the parent class's abstract methods in order to be considered a subclass. What are your thoughts on this?

State a circumstance in which you would prefer an interface over an abstract class. Also, State a circumstance in which you would prefer an abstract class over an interface.

Explain through each question about Classes and Objects in Java.  What is encapsulations and why is it useful? What is an instance method and how does it differ from the static methods we learned previously? What is a mutator method? What is an accessor method? What is a constructor in a Java class? What is an implicit parameter? Please provide an entire coding example to illustrate the answer.

Explain the difference between the following implementations of class A.a. extending class A from class Bb. extending class A from parent abstract class Cc. class A implementing interface D
