Now Java is a very popular language, which means there are many different jobs to choose from. Java software engineers have worked in the industry for 1-3 years, and their annual salary can reach10-150,000. Moreover, the more experience they have in the IT industry, the higher their salary and the more job choices they have. So what can Java do after learning? The following is a detailed introduction to Huo Ying Computer College of Beida Jade Bird.

First, Android development.

Since using Android a few years ago, many Android applications have been developed by Java development programmers. Although Android uses different JVM and encapsulation methods, Beida Jade Bird found that the code is also written in Java language.

Second, the server program

Java has been widely used in the field of financial services, and the banking system uses Java to write electronic trading systems, settlement confirmation systems, data processing projects and other projects. Huo Ying Computer School found that, in most cases, the back-end development of servers uses Java, and most of them have no front-end. They usually receive data from one server (the top layer), then process it and send it to another processing system (the next layer).

Third, big data technology.

Hadoop and other large-scale data processing technologies can be used in Java or other aspects, such as Apache and Accumulo based on Java and ElasticSearcas. But ... IT training in Huo Ying, Huo Ying found that Java does not have much room in this field, but as long as Hadoop and ElasticSearchas continue to grow, Java may still occupy some markets.
