CHALLENGE:

Design and implement a class called Sphere that contains instance data that represents the sphere’s diameter.

Define the Sphere constructor to accept and initialize the diameter, and include getter and setter methods for the diameter.
Include methods calcVolume and calcSurfaceArea that calculate and return the volume and surface area of the sphere.

Include a toString method that returns a one-line description of the sphere of this form:
sphere with diameter X where X is the object’s diameter rounded to 3 decimal places.
Use the following formulas in your class:
Volume = 4/3 PI times cube of the radius
Surface Area = 4 PI times the square of the radius
