    Look at the Scanner class for reading input from a user.

    Looking at the scanner class it still doesn't seem obvious to me...

    reading java for dummies i did find the following:

    Scanner keyboard = new Scanner("System.in");
    char reply;
    reply = keyboard.findWithinHorizon(".", 0).charAt(0);

    So it's in there as you suggested just not easy to find for a newbie like me.

    Scanner s= new Scanner(System.in);
    char aCharacter = s.next().charAt(0);

    The findWithinHorizon() method uses regular expressions which are more complicated than other methods like next() or nextLine().
    If you don't understand my answer, don't ignore it, ask a question.
