| intro
| =====
|
| The jshell tool allows you to execute Java code, getting immediate results.
| You can enter a Java definition (variable, method, class, etc), like: int x = 8
| or a Java expression, like: x + x
| or a Java statement or import.
| These little chunks of Java code are called 'snippets'.
|
| There are also the jshell tool commands that allow you to understand and
| control what you are doing, like: /list
|
| For a list of commands: /help
