Today, you can find Java technology in works and devices that range from the Inter and scientific superputers to laptops and cell phones, from Wall Street market simulators to 畢業(yè)設(shè)計(jì)（論文） 2 home game players and credit cards. There are over 3 million Java developers and now there are several versions of the code. Most large corporations have inhouse Java developers. In addition, the majority of key software vendors use Java in their mercial applications (Lazaridis, 2020). Applications Java on the World Wide Web Java has found a place on some of the most popular websites in the world and the uses of Java continues to grow. Java applications not only provide unique user interfaces, they also help to power the backend of websites. Everybody is probably familiar with eBay and Amazon have been Java pioneers on the World Wide Web. eBay Founded in 1995, eBay enables emerce on a local, national and international basis with an array of Web can find it on eBay, even if you didn39。畢業(yè)設(shè)計(jì)（論文） 1 英文 原文 : The Java programming language and platform have emerged as major technologies for performing ebusiness functions. Java programming standards have enabled portability of applications and the reuse of application ponents across puting platforms. Sun Microsystems39。 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 of Java Java uses many familiar programming concepts and constructs and allows portability by providing a mon interface through an external Java Virtual Machine (JVM). A virtual machine is a selfcontained operating environment, created by a software layer that behaves as if it were a separate puter. Benefits of creating virtual machines include better exploitation of powerful puting resources and isolation of applications to prevent crosscorruption and improve security. The JVM allows puting devices with limited processors or memory to handle more advanced applications by calling up software instructions inside the JVM to perform most of the work. This also reduces the size and plexity 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 recreate the same application 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 tailormade for the growing Inter because it makes it easy to develop new, dynamic applications that could make the most of the Inter39。t know it existed. On a typical day, more than 100 million items are listed on eBay in tens of thousands of categories. on eBay。s largest online marketplace. eBay uses Java almost everywhere. To address some security issues, eBay chose Sun Microsystems39。s 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 has created a Web Service application that enables users to browse their product catalog and place orders. uses a Java application that searches the Amazon catalog for books whose subject matches a userselected topic. The application displays te
