Basic Multiple Interface Implementation

In this problem, you will create a program that implements both Swimmable and Flyable interfaces in a Duck class, then calls each interface method and displays the results to standard output.

Learning Objective: Understand how to implement multiple interfaces in a single class

Overview

Create a Duck class that implements both Swimmable and Flyable interfaces.

Specifications

• Swimmable interface: has void swim() method
• Flyable interface: has void fly() method
• Duck class: implements both interfaces
• swim() outputs "Duck is swimming"
• fly() outputs "Duck is flying"
• In main method, create a Duck instance and call both methods

Output Format

Duck is swimming
Duck is flying
