Hi,
I was following
https://coderanch.com/how-to/java/how-to-create-java-program#SettingJavahomeAndPath
I got to this part:
Checking that your JDK is configured properly
Open the command prompt, go to a directory different from your JDK install directory, and type "javac -version". This should display the version of your SDK. Make sure it is correct. If an error like "Command not found" is displayed, make sure you have correctly set your PATH.
It says that 'javac is not recognized as an internal or external command, operable program or batch file.'
I have attached screen clippings of the directory structure and how I configured the path and JAVA_HOME variables.
thanks for your help!
