【正文】 s acquisition of BEA and Sun before the mon goal of the two panies. This design may eliminate the Java application and the hardware itself between a large number of software layers. In fact, Azul pany many years ago began the attempt to build specialized hardware and Java virtual machine to work together, thus eliminating the traditional operating system. By adding a hypervisor, Oracle eliminates dedicated hardware limitations, let the JVM can run in the data center have been deployed on all hardware platforms, such as Intel, AMD, and Sparcbased systems. ? Advanced garbage collection: a bination of Oracle / BEA and Sun in terms of technical precipitation garbage collection, and now and then how to say there should be a qualitative leap, Sun on the realtime behavior and throughput (Java SE 6 parallel collector) also alone achieved a GC (Java RTS Realtime garbage collection). Jrcokit support less recovery, but it allows you to specify the mode of operation. In addition, support for dynamic mode at runtime collector can choose the best garbage collection policy. The two sides have done a lot of interesting effort and work (Sun39。s Java RTS product advantage, because RTS often require modifying the application code. But Sun39。s JVM has been plagued by performance and management capabilities, but now finally the King once again return to the performance benchmarks, the overall latency and garbage collection techniques to achieve the best results. Although many people think that Sun39。s threading model can easily create parallel threads that execute tasks, but how do you to a single task into multiple slices parallel to enforce it? There are thirdparty software packages can help us, such as Pervasive39。s JRockit and Sun39。s most popular programming platform, but also will promote Java embedded in more devices. Kurian said they would keep the Java Community Process (Java Community Process, JCP) to promote the development of Java, but I doubt Oracle will transform JCP process, because in recent years has exposed many problems, uncooperative participant may delay the Java Specification Request (Java Specification Requests, JSR). Kurian also confirmed, Oracle will continue to provide support for all major operating systems, as well as the popular Java business support program, which will expire for the current version of the JVM and provide longterm support for older versions of Java in a Java program on the maintenance of traditional enterprise , access to security patches and other support is essential. The most interesting is, Kurian39。s HotSpot JVM would be better to run these applications, because JIT (realtime) piler will reoptimize the piled code. Java is still the most enterprise and Web application development preferred language / platform, and continue to grow, Java is free for developers to use, many university puter science also select Java as a programming language courses, although they aura But that does not mean we should not reexamine the future of Java development, especially after the acquisition of Sun by this time. Java SE Oracle has released Java39。 ? for building RIA applications JavaFX, for the PC, mobile devices and TV (settop boxes, Bluray player, etc.) on media applications. So if someone says, I am a Java developer, they need to clarify exactly what field of Java. I am here to discuss from a platform perspective the future of Java, including Java SE, Java EE, Java ME, JavaFX, tools and languages.Java how big the market? In accordance with Oracle39。 ? for embedded and mobile devices Java ME。?
