Explanation: I have written all the three classes and have filled all the blanks as mentioned in the question.Please upvote if you liked my answer and comment if you need any modification or explanation.

//Cat

public class Cat implements Movers {
   @Override
   public void move() {
       System.out.println("runs like a cat");
   }
}

//Fish

public class Fish implements Movers {
   @Override
   public void move() {
       System.out.println("swims like a fish");
   }
}

//Exam class

import java.util.ArrayList;
import java.util.Collection;

public class Exam{
   public static void main(String[] args) {
       Collection<Movers> movers = new ArrayList<Movers>();
       movers.add(new Fish());
       movers.add(new Cat());
       for (Movers mover : movers) {
           mover.move();
       }
   }
}

Output:
