What is the difference between a class and an interface?

Question

Accepted Answer

A class is a blueprint for creating objects, while an interface is a contract that defines a set of methods that a class must implement.

A class can have attributes, methods, and constructors, while an interface can only have method signatures.
A class can be instantiated to create objects, while an interface cannot be instantiated.
A class can implement multiple interfaces, but can only inherit from one class.
A class can provide default implementations for methods, while an interface cannot.
Classes are used for creating objects with specific behaviors and attributes, while interfaces are used for defining common behavior that multiple classes can implement.
