Explaining the Differences Between Abstract Classes and Interfaces in C#
Abstract Classes vs. Interfaces: Understanding the Key Distinctions
When it comes to object-oriented programming in C#, abstract classes and interfaces play crucial roles in defining the structure and behavior of classes. Let's delve into the key differences between these two concepts:
Abstract Classes
- Definition: Abstract classes serve as blueprints for other classes but cannot be instantiated on their own.
- Methods: Abstract classes can have abstract methods (without a body) that must be implemented by derived classes.
- Fields: Abstract classes can have fields and non-abstract methods with implementations.
- Inheritance: C# allows a class to inherit from only one abstract class.
Interfaces
- Definition: Interfaces define a contract that implementing classes must adhere to.
- Methods: Interfaces consist of method signatures without implementations.
- Fields: Interfaces do not contain fields or implemented methods.
- Inheritance: C# allows a class to implement multiple interfaces.
In summary, the focus keyword in understanding the differences between abstract classes and interfaces in C# lies in the way they are used for defining class structures and establishing contracts for class behaviors.
