What does java do?

java can develop applications, mobile applications, web applications, enterprise applications, embedded systems and other fields. Detailed introduction: 1. Application, you can build user-friendly applications, such as Adobe Acrobat Reader, IntelliJ IDEA, Eclipse, etc.; 2. Mobile application, you can create various types of mobile applications, including games, social media applications, e-commerce Applications, etc.; 3. Web applications, which can quickly develop scalable and secure Web applications; 4. Enterprise-level applications, etc.

The operating system of this tutorial: Windows 10 system, Java19.0.1 version, Dell G3 computer.

Java is a widely used programming language with a very rich application field. It is a high-level, robust and object-oriented language that is widely used in developing applications, mobile applications, web applications, enterprise applications, embedded systems, etc.

First of all, Java is widely used to develop applications and desktop applications. It provides a powerful graphics library and user interface toolkit that allows developers to easily build user-friendly applications. Many famous applications, such as Adobe Acrobat Reader, IntelliJ IDEA, Eclipse, etc., are developed in Java. Because Java is platform-independent, developers can use applications written in Java to run on different operating systems.

Secondly, Java is also widely used in the field of mobile application development. Through Java's Android Development Kit (Android SDK), developers can create various types of mobile applications, including games, social media applications, e-commerce applications, etc. The Android operating system is one of the most popular mobile operating systems in the world, and Java is the main programming language for Android applications.

In addition, Java also has great value in Web application development. Java's lightweight web frameworks, such as Spring and JavaServer Faces (JSF), enable developers to quickly develop scalable and secure web applications. Java's wide application areas also include the development of network servers. Java can be used to write high-performance server programs that support multi-threading and distributed processing.

Java also plays an important role in enterprise-level application development. Java's enterprise-level frameworks, such as Java EE (Java Enterprise Edition), provide developers with a complete set of tools and APIs for building complex and scalable enterprise applications, including enterprise resource planning (ERP) systems, Relational database management system (RDBMS), etc.

In addition, Java is also widely used in the development of embedded systems. Embedded systems refer to small computer systems that are built into other devices or systems, such as smartphones, smart homes, automotive electronic systems, etc. Java's platform independence and strong security features make it an ideal embedded system development language.

In short, Java is a powerful and widely used programming language. It plays an important role in the fields of application development, mobile application development, web application development, enterprise application development and embedded system development. Whether you are an individual developer or a large enterprise, you can get flexible, efficient, and reliable solutions using Java.
