Question
E4.24 Implement a class Balloon that models a spherical balloon that is being filled
with air. The constructor constructs an empty balloon. Supply these
methods:
•void addAir (double amount) adds the given amount of air
•double getVolume () gets the current volume
•double getSurfaceArea () gets the current surface area
•double getRadius () gets the current radius
Supply a BalloonTester class that constructs a balloon, adds 100
cm of air, tests the three accessor methods, adds another 100 cm of
air, and tests the accessor methods again.
