Difference between abstract classes and the Interfaces?

Question

Accepted Answer

Abstract classes are classes that cannot be instantiated and can have both concrete and abstract methods. Interfaces are contracts that define a set of methods that a class must implement.

Abstract classes can have instance variables, constructors, and non-abstract methods, while interfaces cannot.
A class can implement multiple interfaces, but it can only inherit from one abstract class.
Abstract classes provide a way to share code among related classes, while interfaces define a common behavior that unrelated classes can implement.
An abstract class can provide a default implementation for some methods, while interfaces only define the method signatures.
Example: An abstract class 'Animal' can have a concrete method 'eat()' and an abstract method 'sound()', while an interface 'Flyable' can have a method 'fly()'.
