Java Shell is a new tool included in JDK9 defined in JEP 222 to introduce REPL (read-eval-print-loop) capabilities to Java. The program provides integrated console-like UI for the Java Shell, leveraging the tool editor capabilities. The app can support the tool with the user project configuration, so the Java Shell is set up to work with project classes and libraries, providing autocompletion out of the box in the editor.
Also, the app greatly extends the capabilities of the commandline tool. Apache NetBeans for Mac can execute the shell as an agent, similar to a debugging agent, on the debugged or run application (currently only J2SE applications are supported, both Ant and Maven-based). Snippets written in JShell can be redefined and tested, even against a running code. When the prototype is ready, it can be saved to a regular Java source file and integrated with the project.
