Excirse #$2$:

Create the following Parent Class Shape$3$D $($getVolume$()$ and getSurfaceArea$()$ return $0\mathrm{.}0)$

$\backslash$table$[[$Shape$3$D$],[-$ color: String$],[+$ Shape$3$D$($String$)],[+$ setColor$()$: String$],[+$ setColor$($String$)$:void$],[+$ toString$()$:String$],[+$ getVolume$()$:double$],[+$ getSurfaceArea$()$: double$]]$

Create three classes that inherit from the class Shape$3$D $($Ball$,$ Box and Cone$)$

Add the appropriate attributes to each class and implement the constructor that calls the super constructor.

Override the toString$()$ method of each class.

Override the getVolume$()$ method to calculate and return the volume of each class.

Override the getSurfaceArea$()$ method to calculate and return the surface area of each class.

Create a Test$3$DShapes class to test what you have done.

Create three objects, one of type Ball, one or type Box, and one of type Cone

Add the three objects to an arraylist of Shape$3$D$.$

Loop through all objects of the arraylist and print all objects using the toString method, then print the volume and the surface area of each shape method within the same loop.

Print the object with the biggest volume.

Print the total surface area for all shapes.
