Most people choose Java just because they have heard that Java has a bright future, Java is easier to find a job, and the Java language has always been in the top three on the TIOBE rankings, etc. However, there is nothing in mind about the specific goodness of Java. Conceptual. This article answers the prospect of learning Java for you.
1. The development prospects of Java engineers
As one of the most popular network programming languages, java language has played an important role in today's information society. Java language has the characteristics of object-oriented, cross-platform, security, multithreading, etc., which makes java an ideal development language for many application systems.
Java applications can be said to be ubiquitous, from desktop office applications to network databases and other applications, from PCs to embedded mobile platforms, from Java applets to large-scale J2EE enterprise-level solutions, Java is everywhere In the United States, even in large-scale space projects in the United States, Java is used to develop control systems and related software.
Java with such a wide range of uses has created the brilliance of Java engineers, making it a leader in the field of software engineers! Java software engineers use Java as a development tool to complete the software programming, development, testing, maintenance and upgrading of software products.
With the rapid development of the Internet, Web applications have become increasingly widespread, and the Java language has also developed rapidly. In 1994, Gosling used Java to develop a new type of Web browser with high real-time performance, reliability, security, and interactive functions. It does not depend on any hardware platform and software platform. The name of this browser is HotJava, and it was officially published in the industry together with the Java language in 1995, which caused a huge sensation, and the status of Java was subsequently affirmed. Since then, the development has been very rapid.
Java is a popular computer programming language in the world, and it is an object-oriented programming language that can write cross-platform application software. This can be summarized as Java has its own unique advantages: the language is simple, it is an object-oriented, distributed application and safe, and the architecture is neutral and portable. Importantly, it is a dynamic language.
Statistics from authoritative statistical agencies-among all the demand for software development talents, the demand for Java engineers reaches 60% to 70% of the total demand. The salary of Java engineers is relatively high. Generally speaking, it is a normal salary for engineers with 3 to 5 years of development experience to have an annual salary of 200,000 yuan.
A convenient way for college students majoring in computer science to become Java engineers is to participate in Java vocational skills training with actual combat projects as the main teaching method, so as to effectively shorten the gap between the specific employment needs of the enterprise.

There are 2.5 billion Java devices running Java in the world, more than 4.5 million Java developers are active in every corner of the earth, and tens of millions of Web users experience the power of Java every time they go online.
Today, Java runs on 708 million mobile phones, 1 billion smart cards and 700 million PCs, and provides a powerful platform for 28 compatible application servers. So many applications have completely changed the lives of users. More and more companies have improved their production efficiency because of the use of Java. In China, more and more users have reduced costs and enjoyed life because of Java.
Dr. James Gosling, Vice President of Sun, Academician of Sun Research Institute, and Chief Technology Officer of Software Department, is known as the "Father of Java Technology". As an academician of Sun Research Institute, he personally designed the Java language and completed the original compiler and virtual machine of Java technology. Under his leadership, Java has now become the Internet's standard programming model and the de facto standard for distributed enterprise-level applications. Its cross-platform technical advantages have brought epoch-making changes to network computing.
1. Java and e-commerce
E-commerce is a hot topic nowadays. However, traditional programming languages are difficult to be competent in e-commerce systems. E-commerce requires program codes to have basic requirements: safe, reliable, and at the same time require the ability to conduct business with customers all over the world running on machines on different platforms.
With its strong security, platform independence, hardware structure independence, simple language and object-oriented, Java occupies an unparalleled advantage in network programming languages and has become the language for implementing e-commerce systems.
2. Java enterprise application development
Java EE is currently the mainstream framework technology for developing enterprise-level Web applications. It forms two core framework technologies together with Microsoft's MS.NET in today's enterprise-level project development. Mainstream application server and integrated development tool for Java EE.
The main content includes the core structure of the JavaEE framework, application server, integrated development tools, Servlet component programming, request processing programming, response processing programming, session tracking programming, ServletContext object and application, filter programming, device programming, JSP, EL and JSTL, JNDI Service foundation and programming, JDBC service programming, JavaMail programming and JavaEE MVC architecture applications.
3. Java website construction
In recent years, the website construction business has been showing a rapid upward trend, and the industry market is getting bigger and bigger. As far as the domestic situation is concerned, the developed coastal provinces and cities have greater market demand than the central and western provinces and cities, and the popularization of services is also in place. Many industries are competing to build corporate websites and carry out online marketing. The application of new technologies will make the construction of corporate websites more attractive.
Java programming language, .net technology and server CDN technology will also make the website structure closer, access more fluent, and more adaptable to new requirements. However, the current market analysis Java is too expensive to make a website, and the hardware requirements are relatively high. Small and medium-sized enterprises will give up, but large enterprises still prefer Java technology.
4. Java game programming
For game development, because it involves more complex situations, the development process is often a process of continuous modification, and it is very important that the game content can be easily modified.
For many game engines, they have their own script interpreters to interpret some custom game scripting languages (usually imperative scripts, such as moveplayer(intx, int y), playersmile(), etc.) , Others provide scripting languages such as lua and rubby to access the game engine.
Due to its virtual machine characteristics, Java itself can be used to write game scripts. At present, there are scripting languages such as beanshellgroovy that can easily and seamlessly interact with the Java language, which greatly facilitates Java game programming.
2. Java engineer career direction
1. Become a manager, such as product development manager, technical manager, project manager, etc. to continue;
2. The second is the road to technical work, becoming a senior software engineer, demand engineer, etc.
The general monthly salary of Java software engineers is in the range of 6000-10000 yuan, far exceeding the average monthly salary of 2500 yuan for fresh graduates. Generally speaking, the salary of a Java senior software engineer with a year of work experience is roughly around 100,000 to 130,000 per year.
Java employment direction: Can be engaged in JSP website development, Java programming, Java game development, Java desktop programming, and other work related to Java language programming. Can enter telecommunications, banking, insurance professional software development companies, etc. to engage in software design and development.
