Design an abstract class named Bird to represent a bird. The class contains an void sing() method to print This bird sings. Design an interface named Flyable to represent anything can fly and contai

ns a void fly() method. The Bird class should implement the Flyable interface and override the fly() method to print This bird flies. Additionally, the Bird class should have a protected string field named color to represent the color of the bird. The class should have a constructor that takes a string parameter to set the color of the bird. Finally, the Bird class should have a public getColor() method that returns the color of the bird. Here's an example implementation in Java:

public interface Flyable {
    void fly();
}

public abstract class Bird implements Flyable {
    protected String color;

    public Bird(String color) {
        this.color = color;
    }

    public String getColor() {
        return color;
    }

    @Override
    public void fly() {
        System.out.println("This bird flies.");
    }

    public abstract void sing();
}

public class Sparrow extends Bird {
    public Sparrow(String color) {
        super(color);
    }

    @Override
    public void sing() {
        System.out.println("This bird sings.");
    }
}
