Java is the most important single computer language in use today. The proprietor of Java, Oracle, proudly claims that the language is used on over three billion devices world-wide. Java is used to write the complete range of applications from large commercial and industrial systems to low-level programs for embedded firmware. Java Quick and Easy is for students starting a first course in object-oriented programming using Java. The approach is practical and 'hands-on' - the student starts writing working programs from day one, starting with the traditional 'Hello World'. Chris Payne quickly guides the student through the basics of Java - packages, classes, methods, data types and objects. Soon the student becomes confident at programming using files, arrays, the Abstract Windows Toolkit(AWT) for graphical and Windows programming, animation, event handling, applets, the Swing classes, multithreading and using Java for network programming.. The theoretical ideas of object-orientation are discussed as they arise and are summarized in a separate appendix. By the end of the course, the student will be able to write safe, well-constructed Java programs.
