Is it possible to find a job in Java? First, let's see what you can do after learning Java.

One of the big data technology

Hadoop and other big data processing technology are using Java or other, such as Apache's Java-based HBase and Accumulo and ElasticSearchas. ElasticSearchas can grow, Java still has the potential to occupy a part of this market.

Second, the embedded field

Java in the embedded field has a lot of room for development. On this platform, you only need 130KB to be able to use Java technology (on smart cards or sensors). Initially, Java was designed to work on embedded book devices. In fact, this is just one of those areas where it was a "write once, swim anywhere" project, and now it looks like it is.

Three: Web domains

Similarly, Java occupies a large part of the e-commerce domain as well as the web development domain. You can create web projects using many different frameworks, SpringMVC, Struts 2.0 and frameworks.

Even simple servlets, jsp and struts based websites are popular in government projects. For example medical ambulance, insurance, education, defense and other different departmental websites are developed on Java basis.

Four, server programs

Java is widely used in the financial services industry, many multinational investment banks such as Goldman Sachs (Goldman Sachs Investments), Citigroup (Citigroup), Barclays (Barclays Bank) and other banks, are using Java to write front-end and back-end electronic trading systems, settlement and confirmation systems, data processing projects. settlement and confirmation systems, data processing projects, and other projects.

Mostly, Java is used for server-side development, but most don't have any front-end; they usually receive data from one server (the upper level), process it, and send it to another processing system (the next level of processing).

V. Software tools

Many commonly used software and development tools are written and developed using Java. For example, Eclipse, IneteliJIdea and Netbans IDE.

Sixth, high-frequency trading

Java platform dramatically improves the characteristics of this platform and instant compilation, he was also able to pass the data like C++. It is for this reason that Java has become the language for programmers to write trading platforms, because although the performance is not better than the native language, you can bypass its security, portability and maintainability to run at a much faster speed.

Seven, J2ME system

With the emergence of IOS and Android in recent years, almost dominated the J2ME market, but there are still low-end Nokia, Samsung cell phones using J2ME. most of the mobile games of this era, cell phone applications are written using a part of J2ME MIDP and CLDC to adapt to the Android system. But J2ME is still popular in products like Blu-ray, magnetic cards, and set-top boxes. Communication applications are so hot because Nokia's phones still support J2ME.

VIII. Scientific Applications

Today, Java is still the best choice for scientific applications, including natural language processing. The main reason is because Java is better than C++ or other languages relative to its security, portability, maintainability, and concurrency of other high-level languages.

9. Trading systems

Third-party trading systems, which are now a large part of the financial services industry, are also written in Java. For example, the popular trading platform Murex, which is also written in Java, connects with many bank front offices to provide services.

As a long-established development language with a long history, Java has a wide range of applications in the financial industry, banking, e-commerce, government and other fields, and there is plenty of room for any good programmer who chooses to learn Java. And, according to the data of the job set, the national average salary of java: ?12820/month, taken from 472311 samples. java is in great demand for recruitment in the first-tier cities such as north, south and deep.

As long as you have a good grasp of technology, it is very easy to find a good job. On the other hand, if you don't have a good grasp of the technology, you will definitely encounter difficulties in finding a job. The best thing is to find a face-to-face school system to learn. You can go to Qianfeng audition to see, personally feel, to see if you can learn Java, difficult or not, is it worth learning.
