  1. Understanding the Difference between Abstract Classes and Interfaces Welcome to this informative presentation where we will explore the key differences between abstract classes and interfaces. Gain a deeper understanding of these concepts and learn when to use each one effectively.

  2. Abstract Classes: The Backbone of Object-Oriented Programming Definition An abstract class provides a blueprint for derived classes to inherit from while allowing the class itself to remain incomplete. Characteristics Abstract classes can have both abstract and non-abstract methods, and they allow method implementation. Examples Some well-known examples of abstract classes include the Number, InputStream, and OutputStream classes in Java.

  3. Interfaces: A Contract for Implementing Behavior 1 2 3 Definition Characteristics Examples An interface defines a set of methods that a class must implement, effectively providing a contract for behavior. Interfaces can only have abstract methods, and they do not allow method implementation. Popular examples of interfaces include the Comparable, Serializable, and ActionListener interfaces in Java.

  4. Differences between Abstract Classes and Interfaces Syntax and Usage Abstract classes are declared using the "abstract" keyword and used with the "extends" keyword, while interfaces are declared using the "interface" keyword and used with the "implements" keyword. An abstract class can provide both abstract and non-abstract methods, and a class can only extend one abstract class. On the other hand, a class can implement multiple interfaces, but interfaces can only have abstract methods. Inheritance and Implementation

  5. Benefits and Use Cases of Abstract Classes 1 When to Use Abstract Classes Abstract classes are best used when creating a base class that includes some default behavior while allowing flexibility for derived classes to define their own specific behavior. 2 Advantages of Using Abstract Classes They provide code reusability, allow a mix of method implementation and abstraction, and facilitate the creation of hierarchies with common functionality.

  6. Benefits and Use Cases of Interfaces When to Use Interfaces Advantages of Using Interfaces Interfaces are valuable when you want a class to adhere to a specific contract, allowing for loose coupling and multiple inheritance of behavior. Interfaces help achieve modular and flexible code, promote code reuse, and allow for easy unit testing and mocking.

  7. Conclusion Understanding the distinction between abstract classes and interfaces is crucial for mastering object-oriented programming principles. Both have their own unique purposes and benefits, and choosing the right one depends on the specific requirements of your application.
