CMIS 345
Week 6

Read 11.2 Abstract classes.

Make an abstract class Shape3D
that has abstract methods getArea(), getVolume(), and getClassName().
Fields x, y, and z representing the "center" of a 3D object.
A constructor that initializes it from its parameters.
A toString method that returns the 3 coordinates of the center as a String.
A concrete method getCenter that returns an array of the 3 coordinates of the center.
A static/class field numberShapes and a public method that returns its value.

Make Sphere, Cone, and Cylinder concrete subclasses of Shape3D.
Each has a radius field, Cone and Cylinder also have a height field.
Each implements the abstract methods appropriately for its type of object.
Each overrides toString and appends its fields to the center's coordinates that the superclass's toString returns.  i.e. call super.toString()
Each has three constructors: a 0-arg, one with just radius [and height], the third
with radius [and height] and the center's 3 values.  Minimize the amount of code
by using super and this constructor calls.
Each has a static/class field number[Classname]s and a public method that returns its value.

Use TestShape3D to test your classes.
Here's the output from running it:
