Answer 1

public interface Animals {
    void callSound();

    int run();
}

public abstract class Feline implements Animals{
    @Override
    public void callSound() {
        System.out.println("roar");
    }
}

public abstract class Canine implements Animals{
    @Override
    public void callSound() {
        System.out.println("howl");
    }
}

public class Lion extends Feline{
    @Override
    public void callSound() {
        super.callSound();
    }

    @Override
    public int run() {
        return 40;
    }
