I'm pointing out that debug messages that are written to the terminal nanoseconds before it closes are useless. Not that you need the debugging messages for this particular program. It seems you're the ones with the programming issues. I'm not trying to pick a fight here, I'm just passing on a valuable point. If you've got a chance to read Hardcore Java, the author will bring up more even more points that relate to this.

Perhaps there is a way to call a new terminal to open with the remaining code while closing the old one? I have no idea how to do that... but that would guarantee a clear terminal/DOS window etc...

That is, unless

(Toggle Plain Text)

System.out.print ("\033c");

does clear all the contents of the terminal window so that even if you scrolled up you could not find the text cleared.

As far as the suggestion about the GUI, he/she is quite correct. A GUI just draws a new layer over the text and it appears to disappear. However making a GUI window of the right size, right color, centered in the computer screen, with font of the right size, right color centered in the GUI that accepts inputs and displays outputs is like five times the code you originally posted. Thus, making the GUI might be something of a pain.

perhaps you should check the dates on topics...

I'm not trying to argue with either of you, and I don't really know that much about the issue. But it doesn't seem like that big of a deal, and if it is, there's probably a way to solve it. Such as .... make the system wait x seconds before clearing the screen if an exception was thrown beforehand.

you need to use

(Toggle Plain Text)

 while (true)

because it means loop forever

and you need

(Toggle Plain Text)

        if(again == 'y')
        {
            play = 1

              else
               break;
        }
         if(again == 'n')
        {
            play--;

try this it might work

How do I clear the screen?
