Abstract class vs interface?

Question

Accepted Answer

Abstract class is a class that cannot be instantiated and can have both abstract and non-abstract methods. Interface is a contract that a class must adhere to.

Abstract class can have instance variables, constructors, and non-abstract methods.
Interface can only have constants and abstract methods.
A class can implement multiple interfaces but can only extend one abstract class.
Abstract class provides a common base for multiple classes, while interface defines a common behavior for unrelated classes.
Example: Abstract class 'Animal' with abstract method 'makeSound'. Interface 'Flyable' with method 'fly'.

Accepted Answer
