An abstract class can have method implements and abstract method, while an interface only contains abstract method (before Java 8) . Abstract classes support single inheritance, whereas interfaces support multiple inheritance.

Question

Accepted Answer

Abstract classes can have both implemented and abstract methods, while interfaces can only have abstract methods. Abstract classes support single inheritance, interfaces support multiple inheritance.

Abstract classes can have both implemented and abstract methods, providing more flexibility in design.
Interfaces can only have abstract methods, promoting a more strict contract for implementing classes.
Abstract classes support single inheritance, allowing for a hierarchical structure of classes.
Interfaces support multiple inheritance, enabling a class to implement multiple interfaces.
Example: Abstract class 'Animal' with implemented method 'eat' and abstract method 'sound'. Interface 'Flyable' with abstract method 'fly'.

An abstract class can have method implements and abstract method, while an interface only contains abstract method (before Java 8) . Abstract classes support single inheritance, whereas interfaces support multiple inheritance.
