Java programming language, in which industry applications are more sought-after? __java

In the programming language rankings, Java is the first, why learning Java is so popular. It is in our reality in the Internet where the application. What can you do after you have finished your studies?

When you install Java on your desktop, you will get an answer, or Oracle will tell you that more than 3 billion of the devices are running Java. Most big companies use Java in a different way. Many server programs are written in Java to handle more than tens of millions of data per day, the network 4 of the trading system is also written in Java, such as Lmax trading platform system, which covers the internal path of the blocking internal communication thread, disruptor.

In this article, we'll see a lot more pertinent examples of which projects are done on a Java basis and which areas and departments are using Java.

 

Android Apps

If you are still looking for Java where to use, you do not have to search for, your side is. Open Android phones, open an app, and they're completely in the Java language, searching for Android API documents from Google, and you'll find that it's surprisingly similar to Java's JDK documentation.

server programs applied in the financial industry

Java is widely used in financial services, and many multinational investment banks, such as Goldman Sachs, Standard charted (Standard Chartered bank) and other banks, use Java to write front-end and backstage electronic trading systems, clearing and validation systems, Data processing projects and other projects.

website

Similarly, Java occupies most of the seats in the area of E-commerce and web development. You can use many different frameworks to create Web projects, springmvc,struts2.0, and frameworks. Even simple servlet,jsp and struts based sites are also popular in government projects. For example, medical care, insurance, education, defense, and other sites for different departments are developed on a Java basis.

software Tools

Many common software and development tools are written and developed using Java. such as Eclipse,inetelijidea and Netbans IDE.

Trading System

Third-party trading systems, now a big part of the financial services industry, are also written in Java. For example, the popular trading platform, Murex, is also written in Java and is connected to many of the bank's front desk and provides services.

J2ME System

With the advent of IOS and Android in recent years, almost occupy the J2ME market, but still have low-end Nokia, Samsung mobile phone use J2ME. Most mobile games of the era, mobile apps are used in a part of the J2ME MIDP and CLDC written to fit the Android system. But J2ME is still popular in Blu-ray, magnetic card, set-top box products. Communication applications are so hot because Nokia's phones still support J2ME.

embedded Field

Java in the embedded field of development space is very large. On this platform, you can use Java technology (on a smart card or sensor) with only 130KB. Initially, Java was designed to work on embedded book devices. In fact, this is just one of the areas, this is just the original "once written, casual swim" project, now looks like this.

Large Data Technology

Hadoop and other large data processing technologies are based on Java or other HBase and Accumulo and Elasticsearchas, such as Apache. But Java does not take up much space in this area, but as long as Hadoop and Elasticsearchas can grow, Java still has the potential to occupy a part of the market.

High-frequency trading space

The Java platform dramatically improves the features and just-in-time compilation of the platform, and he can also pass data like C + +. It is for this reason that Java has become a language for programmers to write trading platforms, because although performance is no more than the native language, you can avoid its security, portability and maintainability to run at a faster rate.

Scientific Application

Today, Java remains the best choice in scientific applications, including natural language processing. The main reason is that Java is better than C + + or other languages for its security, portability, maintainability, and other advanced language concurrency.

Java is the default software industry's application development language, in the financial services industry, the large use of investment banking and e-commerce applications space, any study of Java scholars have a bright future.
