An example of an AI chatbot conversation about the differences between annotations and interfaces.
What are the differences between annotations and interfaces in programming?
Annotations are metadata that provide information about the program, while interfaces define a contract for classes to implement.
Can you give me examples of each?
Sure! An example of an annotation is @Override in Java, which indicates that a method overrides a superclass method. An interface example is Runnable, which classes can implement to define a task that can be run.
Are annotations only used in Java?
No, annotations are used in various programming languages, including C#, Python, and JavaScript, each with its own syntax and purpose.
How do I decide when to use an annotation versus an interface?
Use annotations when you need to provide metadata or configuration, and use interfaces when you want to define a set of methods that must be implemented by a class.
