What can you do by learning java?

Java can do many things, such as: 1. Android application development; 2. Financial industry application development; 3. Server-side development; 4. Embedded field; 5. Game development; 6. Software development ; 7. Big data technology; 8. Scientific applications, etc.

With the development of the Internet and the advancement of Java technology, countless jobs have been created in recent years, but the supply exceeds demand. The following article will introduce to you what you can do by learning and mastering Java. I hope it will be helpful to you.

What can you do by learning Java?

1. Development of Android applications

Since Android just started, many Android applications today are developed by Java programmers. Although Android uses different JVMs and different packaging methods, the code is still written in Java language.

2. Development of financial industry applications

Java is widely used in the financial services industry. Many 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.

3. Server-side development

JAVA occupies an extremely important position in server-side development.

4. Embedded field

The embedded field seems to be tailor-made for Java. Java has been favored by the embedded field because of its many advantages, and has received a large number of research and development applications. Since Sun proposed Java technology (Java Language Specification and Java Virtual Machine Specification) in 1993, the application and research of Java has been gradually increasing. Its application and research scope covers a wide range, mainly covering the following fields:

1), super computing field, such as JPVM (Java ParallelVirtual Machine), PJVM (Parallel Java Virtual Machine), Java Grand, etc.;

2), enterprise computing field, such as J2EE, Grid , Web service, etc.;

3), embedded computing field, such as PersonalJava, embedded Java and Card Java, etc.

5, game development

Typical applications are mobile games (mainly in this area in China): This is the world of J2ME. In fact, the application scope is very wide, but domestic development is not enough.

6. Software development

Many commonly used software and development tools are written and developed using Java. Such as Eclipse, IneteliJIdea and Netbans IDE. They are all written in Java

7. Big data technology

Many Hadoop and other big data processing technologies use Java.

The application fields of Java big data are very wide and can be simply divided into several categories:

●Basic big data service platform, large and medium-sized commercial applications include what we often call enterprise-level applications ( Mainly refers to complex software systems of large enterprises), various types of websites, etc.

● Data analysis fields, such as image analysis, speech recognition, spatial analysis, user analysis, visualization, etc.

● The establishment of various data sources and the formation of data markets in meteorology, transportation, media and entertainment and other fields.

8. Scientific Applications

The security and portability of Java give Java a huge space in scientific applications, financial services, and more.
