JShell /-n command

[Paul Deitel]

Is the command 

	/-n 

actually useful? Chances are, if you have any decent number of snippets, you will not recall more than the last few you typed. 

You can already execute the last valid snippet with /!.

For anything else, you’d probably have to do a /list to see what valid snippets you have. At that point, rather than doing /-n, you’d just use /<id> to execute a given snippet.

One point of emphasis in many JShell presentation has been how it’s useful for beginners. I’ve been teaching beginning programmers for 25+ years. A beginner seeing options like this will only get confused. 

I recommend removing /-n as an option.
