Help me pls with this

public class Solution { public static void main(String[] args) { CanSwim creature = new Orca( ) { @Override public void swim() { } @Override CanSwim getCurrentCreature() { return null; } }; creature.swim(); creature = new Whale( ) { @Override public void swim() { } @Override CanSwim getCurrentCreature() { return null; } }; creature.swim(); creature = new RiverOtter( ) { @Override public void swim() { } @Override public void walk() { } }; creature.swim(); } public static void test(CanSwim creature) { creature.swim(); } interface CanWalk { void walk(); } interface CanSwim { void swim(); } static abstract class SeaCreature { public void swim() { SeaCreature currentCreature = (SeaCreature) getCurrentCreature(); currentCreature.displaySwim(); } private void displaySwim() { System.out.println(getCurrentCreature().getClass().getSimpleName() + " is swimming"); } abstract CanSwim getCurrentCreature(); } static abstract class Orca extends SeaCreature implements CanSwim { } static abstract class Whale extends SeaCreature implements CanSwim { } static abstract class RiverOtter implements CanSwim, CanWalk { } }

All you have to do is extend/implement the proper classes/interfaces and nothing else. They don't make it clear but the code doesn't actually have to work it just needs to compile. Frustrating I know...

To implements method just click ctrl + I on inteliJ ide

Find logical parent interfaces for Whale, Orca and RiverOtter and implement them using the 'implements' keyword. The requirements will help you till the end. Don't forget to implement proper interface for the SeaCreature class too.

Just go on following the requirements one by one and you are done..

You fixed it? Can you please tell me?
