Assume you are given an int variable named sum and a 2-dimensional array of ints that has been created and assigned to a2d. write some statements that compute the sum of all the elements in the entire 2-dimensional array and assign the value to sum.

Pp 4.1 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 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.
