Please extend our Beetle Game and support both regular two-eyed beetles, four-eyed beetles, and four-eyed one-horn rhino beetles.

Please

1) Design a class, named FourEyedBeetle, which extends the Beetle class.

Hints:

- Consider how to represent the inheritance relationship between Beetle class and the FourEyedBeetle class?

- Consider which properties and methods should be included in the FourEyedBeetle class?

2. adjust or implement the methods in the FourEyedBeetle class.

4) Adapt BeetleGame class for the FourEyedBeetle class

Hints:

- Consider how to create a specific beetle, based on condition (add one more constructor)

- Check whether we need to change play() and takeTurn() methods

5) Design a class, named FourEyedOneHornedRhinoBeetle, which extends the Beetle class.

Hints:

- Consider how to represent the inheritance relationship between FourEyedBeetle class and the FourEyedOneHornedRhinoBeetle class?

- Consider which properties and methods should be included in the FourEyedOneHornedRhinoBeetle class?

6) adjust or implement the methods in the FourEyedOneHornedRhinoBeetle class.
