This series explores the technical aspects that will determine the development of today's and future Java™ development. Java Development 2.0 will be developed faster and faster, thanks to innovation in the open source field and the commercialization of hardware. You can lease other people's hardware platforms to host your own applications (mainly assembled using open source libraries, tools, and frameworks)

Objective:class file structure, classes loading mechanism, class loader, runtime data area These four Java technology systems are very important knowledge, after learning these, we know that a class is loaded through the class loader to the virtual machine, stored in the runtime data area, And we also know that the code in our method is compiled into bytecode stored in the method table in the Code property, then the virtual machine how to execute the

Velocity is a Java-based template engine. It allows web page designers to refer to methods defined in Java code. Web designers can work in parallel with Java programmers to develop MVC-mode Web sites, which means that Web page designers can focus only on creating well-designed sites, and programmers can focus only on w
