> WELCOME TO Introduction to Programming Using Java, the fourth edition of a free, on-line textbook on introductory programming, which uses Java as the language of instruction. Previous versions have been used as a textbook for an introductory programming class at Hobart and William Smith Colleges. See http://math.hws.edu/eck/cs124/ for information about this course. This on-line book contains Java applets, many of which require Java 1.3 or higher. To see these applets, you will need a Web browser that uses a recent version of Java. To learn more, please read the preface.
