    Default Java Scanners and loop problems

    I'm trying to solve Java problems with Scanners, and I've run into a problem with loops.

    I'm trying to run a program that uses "new Scanner(System.in)" to get input from a user, after I get the input I go down to a method with a loop in it and the condition of the loop is (s.hasNext()) I'm trying to manipulate each token that is entered in by the user, however after the loop should terminate, it goes back up to that loop and just stops, waiting for more input, the program never terminates.

    Read the API doc for the hasNext method it may block waiting for more input.

    For suggestions, post a small program that demonstrates your problem.
