The Java Shell
Kishori Sharan · Apress eBooks · 2017
The Java shell, which is called JShell in JDK 9, is a command-line tool that provides an interactive way to access the Java programming language. It lets you evaluate snippets of Java code instead of forcing you to write an entire Java program. It is a REPL (Read-Eval-Print loop) for Java. JShell is also an API that you can use to develop an application to provide the same functionality as the JShell command-line tool.
