Hi Friends,
I have a loop in my program that asks the user to enter a number,I want that if the user presses the 'enter' key instead of entering any number,then the loop should exit.
But I don't know how to detect the 'enter' key as I am not using any GUI or ActionListener classes,is there some ASCII code for the enter key,that I can read and exit the loop.
Please help.

assuming you're using readLine() to red the input you would check for an empty string

String input = stdin.readLine();
if (input.length()==0)
   // <return> entered
