2. getNext - Returns the next element in the collection as an Object class object.
2. NameCollection class
1. Implements the Enumerate Interface
2. Instance variables
1. Array of 10 Strings to store the names
2. Partially filled array value to keep track of how many names on in the array

Pp 4.1 design and implement a class called sphere that contains instance data that represents the sphereβs diameter. define the sphere constructor to accept and initialize the diameter and include getter and setter methods for the diameter. include methods that calculate and return the volume and surface area of the sphere (see pp 3.5 for the formulas). include a tostring method that returns a one-line description of the sphere. create a driver class called multisphere, whose main method instantiates and updates several sphere objects.
