so what can I do after learning Java? I'll tell you below!

I. 23 years of development of Java

It has been 23 years since Java was officially released in 1995. In the past 23 years, the Java language is constantly evolving, and its technical application is also expanding and progressing.

in p>1995, from the first year of its birth, 83, web pages were made using Java technology.

2. Skills to be mastered as a Java engineer

1. Web front-end technologies (HTML5, CSS, JS, jQuery, Ajax)

2. Internet architecture (Nginx, Redis, MQ)

3. Web server-side programming (Java Foundation, Servelt, SSH, SSM)

. MySQL)

Third, the technical application of Java

1. Android development

Although kotlin can also be used for Android development, Java language is still the mainstream language in the field of Android development. With the development of mobile Internet, Java language has accumulated a large number of cases in the field of Android development in recent years. I believe that with the implementation of the 5G standard, Java will have great application prospects in the future mobile Internet field.

2. Back-end services

Java is a common choice for developing various back-end services. Because Java has mature programs in concurrent processing, transaction processing and security processing, it is a common program for many project teams to adopt Java for back-end development.

3, the field of Web development

Java language has been widely used in the field of Web development. Java language, with its stable performance and good expansibility, has become an important solution for large-scale Internet platforms. In addition, the huge enterprise ERP system can also be realized in Java language, which is a relatively large development market.

4. Do research and development, product manager, testing, operation and maintenance

You can go to large it enterprises, state-owned enterprises, research institutes, banks, private enterprises, private enterprises, industries, enterprises, universities, training and so on.

5. In addition to the above development fields, Java also has certain applications in games, artificial intelligence, scientific computing and other fields. From the perspective of employment, learning Java is a good choice.

6. Generally speaking, working as a Java background development engineer, the specific work is different.

the early stage may be to maintain some systems or develop some systems. There are also application development, android and so on, depending on the specific learning direction and the work direction you choose. You can also be a full-stack engineer if you can.

with the rapid development of internet economy, learning Java programming has become the best choice. I remind you: it is not difficult to learn the basic work of Java, but it is very hard!

answer 2:

what can I do to learn Java development? What jobs need Java programmers? Today, Xiaobian will introduce it to you!

people who are new to Java are confused by what they can do after learning Java. In fact, there are too many things that Java can do. Because of its high security and platform portability, Java is loved by many Java programmers.

mobile games, middleware, software, websites, and now very popular mobile apps, etc., are all written in Java language.

Android is a free and open source operating system based on Linux, and its source code is Java. Therefore, the mobile phone systems seen in the market, such as MIUI, Ali Cloud, Le Frog, etc., are all revised and then released.

Java does Android not only refer to the system, but also the APP. For more developers, they spend more time developing the APP.

3 Java can play games

or you don't know, when Nokia was still very popular, more than 9% of the mobile games you played were developed by Java. Of course, few people have developed it now, and they have all turned to Android. There are also games developed by Java on the computer, the most classic of which is minecraft (MC for short).

4 Java can be used as software

All general programming languages can be used as software, and Java is no exception, such as Eclipse, MyEclipse and other well-known Java development tools. About developing software components, you can learn about JavaSwing programming or awt.

5 other

in addition to the application scope of Java language mentioned above, home appliances such as washing machines and microwave ovens may be controlled by Java language programs. The most important thing is to find one of your interests, specialize in one field, and stick to it to make achievements.
