How to access Java 9 Jshell on Mac

Question

I installed Jdk9 on MAC OSX, and I added the JDK path to bash_profile. When I use the jshell command from the terminal, I get a "Command not found" error. I can get the correct version number when I type the command java -version.

How do I access jshell from terminal? Do I need to include the jdk 9 bin folder path in bash_profile?

Answer 1

Yes. All you have to do is configure in the bash_profile file, which can be done as: $JAVA_HOME/bin

and then confirm the java version at your prompt.

PS : all other variables in bash_profileexcept JAVA_HOMEand PATHin the profile can be ignored.

Answer 2

JDK-9 PATH.

export PATH=/Library/Java/JavaVirtualMachines/jdk-9.0.1.jdk/Contents/Home/bin:$PATH
jshell
