What this article shares with you is about the problems being solved with Java in the real world. The editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article. Without saying much, let's take a look at it with the editor.

We interviewed a number of business professionals, most of whom work related to the Java ecosystem. I asked them some questions about what practical problems they had solved with Java in their careers.

Here are their answers:

1. The server side, big data, large websites and Twitter backend use Java language. These are the most dazzling areas of Java. Internet of things, Android mobile platform, you can use the same language to write mobile and big data server.

2. Pre-cloud merges virtualization and commercial hardware into the cloud. You can easily and quickly create a computer network, regardless of software. Create a local environment and then push it to where you need it. Distributed computing system. Be able to become active on AWS more quickly.

3. Java is so perfect that it can be seen anywhere. It can even be found in embedded systems. This is a great software development language, it solves the management problems in software development, can easily accomplish some things, and it is easy to recruit developers.

4. Java is the safest, most stable and scalable enterprise software. Twitter moved from Ruby to Scala and Java because of its scalability, stability, and programming speed.

5. The Java platform is very efficient for dealing with complex tasks. Can run on a variety of platforms. Java can work on different hardware platforms.

6. There has been no major change since its release in 1995. This is a very stable enterprise software. From the Internet of things and the mobile side, we can see that Java can solve more different problems. Java is more suitable for long-term development than rapid development. We are working with large pizza chains to develop applications that control the temperature, humidity, cooking time and other maintenance of their ovens.

7. There are two bright spots:

1. Java development library ecosystem and open source. We are participating in those high-quality libraries. We have been using these libraries for many years, and we do not need to give back to them all the time. As members of the Eclipse Foundation and Apache, we will help as much as we can. This is mutually beneficial for our company and our developers. We are pleased to be able to give back to open source projects and even "provide funding to support their development."

2. Java OSGi modularization. Modular software established by IBM, Sun and other companies in 1990. It has been developing as a product, becoming more and more complex, can no longer remain flexible, and more and more difficult to maintain. It enables us to develop high-end features and export them to Java, allowing us to challenge our limits.

8. Reactive applications can be responsive in a very short time, expanding and shrinking through the cloud. Elastic systems may also be too stressful to start or run quickly. Reactive applications are scalable and are mostly used in key industries such as energy.

9. In large enterprises, Java has a code base. It can be used almost anywhere, from the Internet of things to servers-everywhere. People often don't see this. They think that all levels of things are written in C or C +. They feel that server pages should get more attention on the Internet, such as the financial system background that is written and run in Cobol.

10. Java affects Android OS, Amazon Kindle, as well as enterprise databases and big data processing (Hadoop and Cassandra are written in Java, Spark is written in Scala, a JVM language). Security, stability and scalability are the characteristics of the Java platform (such as real-time transactions). Because of its performance, stability, and cross-platform capabilities, you can develop with Java on Windows or OSX platforms.

11. It is widely used in enterprise servers, especially large-scale, database-oriented systems, integration between multi-services and multi-platforms, and distributed transactions.

These are the problems that are being solved with Java in the real world. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
