Java programming standards have enabled portability of applications and the reuse of application com
2、ponents across computing platforms. Sun Microsystems Java Community Process continues to be a strong base for the growth of the Java infrastructure and language standards. This growth of open standards creates new opportunities for designers and developers of applications and services .Applications
3、of Java Java uses many familiar programming concepts and constructs and allows portability by providing a common interface through an external Java Virtual Machine (JVM). A virtual machine is a self-contained operating environment, created by a software layer that behaves as if it were a separate co
4、mputer. Benefits of creating virtual machines include better exploitation of powerful computing resources and isolation of applications to prevent cross-corruption and improve security.The JVM allows computing devices with limited processors or memory to handle more advanced applications by calling
5、up software instructions inside the JVM to perform most of the work. This also reduces the size and complexity of Java applications because many of the core functions and processing instructions were built into the JVM. As a result, software developers no longer need to re-create the same applicatio
6、n for every operating system. Java also provides security by instructing the application to interact with the virtual machine, which served as a barrier between applications and the core system, effectively protecting systems from malicious code.Among other things, Java is tailor-made for the growin
7、g Internet because it makes it easy to develop new, dynamic applications that could make the most of the Internets power and capabilities. Java is now an open standard, meaning that no single entity controls its development and the tools for writing programs in the language are available to everyone

To address some security issues, eBay chose Sun Microsystems Java System Identity Manager as the platform for revamping its identity management system. The task at hand was to provide identity management fo

Javas inherent portability allows eBay to move to new hardware to take advantage of new technology, packaging, or pricing, without having to rewrite Java code.Amazon
14、 A has created a Web Service application that enables users to browse their product catalog and place orders. A uses a Java application that searches the Amazon catalog for books whose subject matches a user-selected topic. The application displays ten books that match the chosen topic, and shows th

The user may optionally view one review per displayed title and make a buying decision.Java in Data Warehousing & Mining Although many companies currently benefit from data warehousing to support corporate decision making, new business intelligence approaches continue to emerge that can be powered by Java technology. Applications such as data warehousing, data mining, Enterprise Information Portals and Knowledge Management Systems are able to provide insigh
