    how did you use the System.out.println?

    If you made like System.out.println(out);
    Be sure you have the out variable.

    If you just want to print a word "out",

    System.out.println("out");

    Or, show us your code including the stackTrace( the error )

    This kind of error is new to me....

    Just to confirm, can you show the whole error (StackTrace)?

    I think printing to console is not the problem,
    Just to confirm

    {
    advisor = "unknown";
    desk = "unknown";
    timeAndDay = "unknown";
    persons = new ArrayList<Person>();
    capacity = numberOfApplicants;
    }



    /**
    * Add applicants to the system.
    */
    public void addApplicant (Person newPerson)
    {
    if(persons.size() == capacity) {
    System.out.println("All advisors are busy, please come back later." );
    }
    else {

    Please post the exact error message and tell us more about what you do. Are you writing an applet? Then you don't actually have an "out".

    It's trying to use his System class. He needs to use java.lang.System.out.println().

    LOL, this was funny, I didn't notice the name collision :) hahaha. Good catch Jesdisciple. This only proves again one should look at the problem before giving advice... and also start with the simple things first:)

    Yup, that's like the programmer's lifelong struggle: Make sure it's plugged up first. (BTW, I've been getting a kick out of this, too.)
