Java Programming with Interfaces and Inheritance

To write a Java program that incorporates interfaces and inheritance, follow these steps:

1. Create Interfaces: Define interfaces like CanFight, CanSwim, and CanFly with abstract methods fight(), swim(), and fly() respectively.

2. Implement ActionCharacter Class: Create a class named ActionCharacter with a method fight() displaying "Action characters always fight in the movies".

3. Develop Hero Class: Inherit Hero class from ActionCharacter, override fight() method to display "My hero fights as Van Damme", and add swim() and fly() methods with specific messages.

4. Define Main Class: Create a Main class with a main() method to instantiate Hero object, call its methods, and instantiate ActionCharacter object to call its fight() method.

5. Testing: Run the program to see the expected output.
