An example of an AI chatbot conversation about the difference between abstract classes and interfaces.
What is the difference between an abstract class and an interface in programming?
An abstract class can have both abstract methods and concrete methods, while an interface can only have abstract methods.
Can you give me an example of when to use an abstract class?
Sure! Use an abstract class when you want to provide a common base with shared code for related classes.
And when should I use an interface instead?
Use an interface when you want to define a contract that multiple classes can implement, regardless of their hierarchy.
Can a class implement multiple interfaces?
Yes, a class can implement multiple interfaces, allowing for more flexible design.
What about multiple inheritance? How does that work?
In languages like Java, multiple inheritance is not allowed for classes, but a class can implement multiple interfaces.
