Fix Java Environment Variables Setup

If you encounter difficulties in setting up the Java environment variables, you can try the following solutions:

1. Check the Java installation directory: make sure Java has been installed correctly and take note of the Java installation path.
2. Manually setting Java environment variables: Open the system’s environment variable settings interface, locate the “Path” variable, and add the Java installation path at the end of its value (for example: C:\Program Files\Java\jdk1.8.0_221\bin). Make sure to separate the paths with semicolons.
3. Check if the variable name is correct: make sure the variable name is set to “JAVA_HOME” and the variable value is the path to the Java installation (for example: C:\Program Files\Java\jdk1.8.0_221).
4. Restart the computer to apply the changes to the environment variables.
5. Check for any conflicting Java environment variables: Ensure that there are no conflicting JAVA_HOME or Path variables set; if conflicts exist, consider deleting or modifying these variables.
6. To verify using the command line: open the command prompt window and enter the command “java -version”. If the Java version information is displayed successfully, it indicates that the environment variable is set up correctly.

If the above methods fail to resolve the issue, it could be due to other reasons. You can try reinstalling Java and configuring it correctly. If the problem persists, it is recommended to seek advice from Java’s official support or seek help from a professional.
