Object-Oriented Design and Patterns in Java (the 3rd Edition Chapter 4)

- Create a directory named as the question number and save the required solutions in the directory.

- Each problem comes with an expected tester name. In the directory for a given problem, including the tester and all java classes successfully run this tester.

Exercise 4.18

ClockTester - Write a class ClockIcon that implements the Icon interface type. Draw an analog clock whose hour, minute, and second hands show the current time. To get the current hours and minutes, construct an object of type GregorianCalendar with the default constructor. (Clock hands for the hour, minute, and second are required to be drawn and move to represent a current time. You don't have to draw clock numbers.)
