Question

I need help creating a Java code package in a pyramid with 3 sides (pyramid3) and pyramid with 4 sides (pyramid4) classes as described in the image below

package objectsPackage;

import interfacePackage.ShapesInterface;

public class Pyramid3 implements ShapesInterface {

@Override

publicdouble getArea() {

// TODO Auto-generated method stub

return 0;

}

@Override

publicdouble getVolume() {

// TODO Auto-generated method stub

return 0;

}

@Override

publicvoid displayArea() {

// TODO Auto-generated method stub

}

@Override

publicvoid displayVolume() {

// TODO Auto-generated method stub

}

add four more shape classes, Pyramid4 a 4-sided pyramid, Pyramid3 a 3-sided pyramid, Square, and Cube. You may add more
shapes than these if you would like.
Each new shape class will implement the ShapesInterface.
You will then need to update the ShapeGenerator class to properly generate new objects of these classes.
Note that the TestDriver class never creates variables of the shape classes. It is using variables of the ShapesInteface class to
access the methods of the shape objects.
Once you have made the necessary changes export your Eclipse project to a zip file and submit it to this page.
