Using Java Shell (jshell)

Each chapter comes with executable examples that you can run using jshell.

To get the examples, just clone this repository

  git clone http://github.com/forax/java-guide

Then run jshell (at least Java 14 version)

   jshell --enable-preview

Then you can copy paste the examples inside jshell and see by yourself.

To quit use '/exit', to have have verbose error message '/set feedback verbose', otherwise to get the help '/help'
