Exercise 5 Write a Java program that computes the sum of two rational numbers given by the user.
[Note: If two numbers are rational, then we can write them in the formand for some
integer values of a, b, x and y, and x and y cannot be zero.
Then their sum is:
b
+
y
NA
bx
=
+
yx

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.
