RuntimeError: Java gateway process exited before sending its port number after setting JAVA_HOME

I’m trying to start pyspark using VSCode but i am getting the follow errors:

Java not found and JAVA_HOME environment variable is not set.
Install Java and set JAVA_HOME to point to the Java installation directory.

i have already set the JAVA_HOME = path, here

Moreover, i have downloaded the folders required: here

>Solution :

Try to output the env variable

echo %JAVA_HOME%

and check if it’s correct.

If not correct check again your JAVA_HOME assignment.

Then, close and reopen the command prompt again that runs the java process (or the OS user session) and type java -version to check if it installed successfully.

If the java command fails follow this link.

Follow this link to have more info about JAVA_HOME.
