Create the following classes along with the specified instance data and methods. Make sure you use /** Javadoc comments */ to comment all public classes, constructors, and methods (with the @author, @version, @return, and @param tags as appropriate). Make sure the constructor validates data as specified. All constructors and mutators must throw an IllegalArgumentException when parameters do not match the expected format (listed below). Make all data (including parameters) final if it is not expected/desired to change. Avoid magic numbers; e.g. use public static final double PI = 3.14 instead of simply using 3.14)
