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.

Retype the statements, correcting the syntax errors. system. out. println("num: " + songnum); system. out. println(int songnum); system. out. println(songnum " songs"); note: these activities may test code with different test values. this activity will perform two tests: the first with songnum = 5, the second with songnum = 9. see how to use zybooks.
