Provides a standalone version of the JShell REPL. Anything needed to run JShell independently is contained, so there is no need to install the full JDK. A minimal Java runtime is embedded and compressed using the jlink tool.
This minimal version consists only of the modules necessary to run JShell: "java.base", "jdk.zipfs" and "jdk.jshell".
However the user can manually provide any JDK or custom module on startup with --add-module.
Note that the startup time of JShell 10 was significantly improved.
Caveat: The default JShell editor is not available. An editor can be set in JShell e.g. with /set editor C:/Program Files (x86)/Notepad++/notepad++.exe
Note that the mostly "General Availability" JDK (x64) releases are used and not always the newest patch releases.

Install Java JDK 9 or higher
-
Set environment variable %JAVA_HOME% to the Java installation directory. Replace with the installed version:
set JAVA_HOME = C:\PROGRA~1\java\jdk-<version> -
Add %JAVA_HOME% to the %PATH%, if it is not already:
set PATH = "%PATH%;%JAVA_HOME%\bin" -
Open the command line
