Recent fixes have addressed program input in the jshell tool. So now:

    System.in.read()

works.

However, as reported by Paul Deitel --

...
For example, should I be able to use a Scanner object?

The following creates one
Scanner input = new Scanner(System.in);

But if I then type
int x = input.nextInt();

it appears to execute the statement and wait for input, but I can’t get that input to work. After typing a number and pressing Enter, I just get a blank line. I then have to type Control C to terminate the input. At this point JShell shows

x ==>

and evaluating x then gives 0.

One of the most basic things a new programming student will do is use command-line input statements. I realize they can simply say something like

int x = 32;

but once we show them JShell, they’re sure to try out the above input capability too.

Best,
Paul
