Setting Java environment variables has the following benefits:

• Can easily access Java tools and commands: By setting Java environment variables, you can Easily access Java tools and commands like "java" and "javac" from anywhere. This way, you don't need to enter the full path every time to execute these commands.

• Simplify the development and compilation process: After the environment variable is set, you no longer need to manually specify the installation path of Java when compiling a Java program or running a Java application. The compiler and runtime environment will automatically find the correct Java version and perform related operations, making the development and compilation process more concise and efficient.

• Avoid multi-version conflicts: When multiple Java versions are installed in the system, you can clearly specify which version of Java to use by setting environment variables. This helps avoid conflicts and confusion caused by multiple versions and ensures that the program is using the expected version of Java.

• Improve development efficiency: Setting Java environment variables can improve development efficiency. During the development process, you can call Java tools and libraries at any time without worrying about path issues. In this way, you can focus more on code writing and debugging, improving development efficiency.

In short, by setting Java environment variables, you can easily access Java tools and commands, simplify the development process, avoid multi-version conflicts, and improve development efficiency. This is very beneficial for Java development and compilation.
