Applets
This lesson talks about the basics of applets, advantages of applets over applications, how to load applets in a web page, how to convert applications to applets and how applets work. You should thoroughly understand this lesson before going further in this trail. An applet is a special kind of Java program that a browser enabled with Java technology can download from the internet and run. An applet is typically embedded inside a web-page and runs in the context of the browser. An applet must be a subclass of the java.applet.Applet class, which provides the standard interface between the applet and the browser environment.
Trail: Essential Classes
Exceptions explains the exception mechanism and how it is used to handle errors and other exceptional conditions. This lesson describes what an exception is, how to throw and catch exceptions, what to do with an exception once it has been caught, and how to use the exception class hierarchy. Basic I/O covers the Java platform classes used for basic input and output. It focuses primarily on I/O Streams, a powerful concept that greatly simplifies I/O operations. The lesson also looks at Serialization, which lets a program write whole objects out to streams and read them back again. Then the lesson looks at some file system operations, including random access files. Finally, it touchs briefly on the advanced features of the New I/O API.
Full-Screen Exclusive Mode API
Programmers who use Microsoft's DirectX API may already be familiar with full-screen exclusive mode. Other programmers may be somewhat new to the concept. In either case, full-screen exclusive mode is a powerful feature of J2SETM version 1.4 that allows the programmer to suspend the windowing system so that drawing can be done directly to the screen. This is a slight paradigm shift from the usual kind of GUI program in many ways. In traditional Java GUI programs, the AWT is responsible for propagating paint events from the operating system, through the event dispatch thread, and by calling AWT's Component.paint method when appropriate. In full-screen exclusive applications, painting is usually done actively by the program itself. Additionally, a traditional GUI application is limited to the bit depth and size of the screen chosen by the user.
Advanced Programming for the Java 2 Platform
As an experienced developer on the Java platform, you undoubtedly know how fast moving and comprehensive the platform is. Its many application programming interfaces (APIs) provide a wealth of functionality for all aspects of application and system-level programming. Real-world developers never use one or two APIs to solve a problem, but bring together key functionality spanning a number of APIs. Knowing which APIs you need, which parts of which APIs you need, and how the APIs work together to create the best solution can be a daunting task. To help you navigate the Java APIs and fast-track your project development time, this book includes the design, development, test, and deployment phases for an enterprise-worthy auction application. While the example application does not cover every possible programming scenario, it explores many common situations and the discussions leave you with a solid methodology for designing and building your own solutions.
Client-Side JavaScript Reference
This book is a reference manual for the JavaScript language, including both core and client-side JavaScript for version 1.3. JavaScript is Netscape's cross-platform, object-based scripting language for client and server applications. This chapter documents all the JavaScript objects, along with their methods and properties. It is an alphabetical reference for the main features of JavaScript. The reference is organized as follows: Full entries for each object appear in alphabetical order; properties and functions not associated with any object . Each entry provides a complete description for an object. Tables included in the description of each object summarize the object's methods and properties. Full entries for an object's methods and properties appear in alphabetical order after the object's entry. These entries provide a complete description for each method or property, and include cross-references to related features in the documentation.
