Exercise 1

📄 Description

This exercise involves creating and working with classes and interfaces in Java. The goal is to create the following:

1. A class named "Phone" with attributes brand and model, and a method call(). This method should receive a String with a phone number and display a message in the console indicating that the number is being called.

2. An interface named "Camera" with a method photograph() and another interface named "Clock" with a method alarm().

3. A class named "Smartphone" that inherits from "Phone" and implements both "Camera" and "Clock".

• The photograph() method should display in the console: “Taking a photo”.
• The alarm() method should display in the console: “Alarm is ringing”.

Finally, create a Smartphone object in the main() method of the application and invoke these methods.
