People often ask what can be done by learning Java? Most of them only know that Java can be programmed but don't know what it can do specifically. First of all, as Java ranks first in the programming language rankings, there must be a reason why it can be ranked first in the rankings, so let’s take a look!
1. Android application development
Many Android applications are developed by Java programmers. Although Android uses different JVMs and different packaging methods, the code is still written in Java language. A considerable number of mobile phones support JAVA games, which makes many non-programmers familiar with JAVA. (Recommended learning: java course)
2. Server programs used in the financial industry
Java is widely used in the financial services industry. Many third-party trading systems, banks, and financial institutions choose to use Java for development because, relatively speaking, Java is safer. Large multinational investment banks use Java to write front-end and back-end electronic trading systems, settlement and confirmation systems, data processing projects, and other projects.
In most cases, Java is used for server-side development, but most of them do not have any front-end. They usually receive data from a server (upper level), process it and send it to another processing system (next level). level processing).
3. Website development
Java occupies a certain seat in the field of e-commerce and website development. Developers can use many different frameworks to create web projects, SpringMVC, Struts2.0 and frameworks.
Even simple servlets, jsp and struts-based websites are often used in government projects. For example, websites for medical aid, insurance, education, defense and other different departments are developed based on Java.
4. Embedded field programs
Java has great room for development in the embedded field. On this platform, only 130KB can be used to use Java technology (on smart cards or sensors).
5. Big data technology
Many Hadoop and other big data processing technologies use Java, such as Apache's Java-based HBase and Accumulo and ElasticSearchas.
6. Space development of high-frequency trading
The Java platform has improved the characteristics of this platform and even if it is compiled, it can also pass data like C. It is for this reason that Java has become the language of choice for programmers to write trading platforms, because although the performance is not as good as C, developers can avoid issues such as security, portability and maintainability.
7. Scientific applications
Java is a good choice for scientific applications, including natural language processing. The main reason is that Java has better security, portability, maintainability, and concurrency than other high-level languages than C or other languages.
