What is the job outlook for Java?

For most students, learning a programming language is about getting a better job. Because Java plays an important role in e-commerce, enterprise-level development applications, game programming and many other areas, so even in 2020, learning Java will still be a boom, and the development prospects are predicted to be very considerable.

Combined with e-commerce, enterprise application development, website construction and other industry sectors for everyone to analyze the development prospects of Java.

A, Java and e-commerce

E-commerce is today's hot topic, however, the traditional programming language is difficult to handle e-commerce systems, e-commerce requires the program code has the basic requirements: security, reliability, and the requirement to be able to run on different platforms of the machine with the world's customers to conduct business.

Java with its strong security, platform-independence, hardware structure-independence, language simplicity and object-oriented at the same time, in the network programming language occupies an unparalleled advantage, to become the realization of e-commerce system language.

Two, Java enterprise application development

JavaEE is the development of enterprise-level Web applications is the mainstream framework technology, in today's enterprise-level project development with Microsoft's MS.NET together constitute the two major core framework technology. JavaEE mainstream application servers and integrated development tools.

The main content includes the core structure of the JavaEE framework, application servers, integrated development tools, Servlet component programming, request processing programming, response processing programming, session tracking programming, ServletContext objects and applications, filter programming, ware programming, JSP, EL and JSTL, JNDI service basics and programming, JDBC Services Programming, JavaMail Programming, and JavaEEMVC-style architecture applications.

Three, Java website construction

In recent years, the website construction business has been a rapid rise in momentum, the industry market is getting bigger and bigger. As far as the domestic situation is concerned, the developed coastal provinces and cities than the central and western provinces and cities market demand is large, business popularization work is also in place, many industries have formed a race to build corporate websites, the situation of network marketing. The application of new technologies will promote the construction of corporate Web site more attractive.

Java programming language, .net technology and server CDN technology will also make the site structure more tightly, access more smoothly, more adaptable to the new requirements. But with the current market analysis of Java to do the website cost is too high, the hardware requirements are relatively high, small and medium-sized enterprises will give up, but like large enterprises still prefer Java technology.

Four, Java game programming

For game development, due to the complexity of the situation involved, the development process is very often a process of constant modification, you can easily modify the content of the game is very critical.

For many game engines, there are script interpreters written by themselves, used to interpret some custom game scripting language (generally imperative scripts, such as moveplayer (intx, inty), playersmile () and other things), and others provide, for example, lua and rubby scripting language to access the game engine.

Because of its virtual machine nature, Java itself can be used to write game scripts, and there are now scripting languages such as beanshellgroovy that can easily and seamlessly interact with the Java language, all of which greatly facilitates Java game programming.
