The running environment of java code: 1. Java virtual machine; 2. Server; 3. Desktop environment; 4. Android device; 5. Web browser; 6. Embedded system; 7. Game development; 8 , Scientific computing; 9. Big data processing; 10. Other environments. Detailed introduction: 1. Java virtual machine, which is the main environment for running Java code. When you write a Java program and compile it, you will get a bytecode file, which can be run on any device with JVM installed; 2 , server, etc.

where java code runs

The operating system for this tutorial: Windows 10 system, DELL G3 computer.

Java code can run in multiple environments, including but not limited to the following:

1. Java Virtual Machine (JVM): This is to run Java code main environment. When you write a Java program and compile it, you get a bytecode file that can be run on any device with a JVM installed. JVM is cross-platform, which means that the Java programs you write can run on various operating systems such as Windows, Linux, MacOS, etc., as long as the JVM is installed on these systems.

2. Server: Java is often used for server-side programming. A server can be one or more computers running a specific operating system (such as Linux or Windows Server) on which Java applications and corresponding runtime environments are installed.

3. Desktop environment: Java can also be used to develop desktop applications. For example, Swing and JavaFX are two graphical user interface (GUI) toolkits for Java that can be used to create desktop applications.

4. Android devices: In Android development, developers use Java or its sister language Kotlin to write applications. These applications run on Android devices through the Android Runtime Environment (ART) or the Dalvik virtual machine.

5. Web browser: Through Java's Java Applet technology, Java code can be run directly in a Web browser. However, due to security and performance issues, Java Applets are no longer supported in modern browsers.

6. Embedded systems: The lightweight nature of Java makes it an ideal choice for embedded systems. Java can be used to develop applications for embedded systems that can run on a variety of devices, such as smart home devices, medical equipment, etc.

7. Game development: Java is also widely used in game development. Some game engines and tools, such as LibGDX and jMonkeyEngine, support game development using Java.

8. Scientific computing: Java's numerical computing libraries, such as Apache Commons Math and JScience, can be used for scientific computing and data analysis.

9. Big data processing: Java is also widely used in big data processing. Big data processing frameworks such as Hadoop and Spark support Java.

10. Other environments: In addition to the above environments, Java can also run in many other environments, such as some specific hardware devices, game consoles, and scientific computing environments.

In short, Java is a general-purpose programming language that can run in a variety of environments, including servers, desktop environments, mobile devices, embedded systems, etc.
