error says "can not find method.....

[willemjav]

1) when I have an inner clase called:

 public class SingleRoomInfo  { // principle class holds all room info
       
       private JLabel panelref,firstname, lastname, pianoicon, 
               roomfree, reserved ,endtime;
       

       public void setFirstName(JLabel fn)  {
           firstname = fn;
       } // more methods etc.
}

2) and I declare the next field in the main clase:
private SingleRoomPanel[] singleroompanel;

3) and Initialize the above like this:

 singleroompanel = new SingleRoomPanel[MAXROOM]; // initialize the 
        for (int i = 0; i < singleroompanel.length; i++) { // roominfopanrl array
          singleroompanel[i] = new SingleRoomPanel();
        }

4) why I get an error when saying in a other method
singleroompanel[panelcount].setFirstName(new JLabel("firstname"));

(error says "can not find method setFirstName")

why can't programming be easier......

Please show the offending code in the context in which the error occurred.

[willemjav]

line 44 is the accused one

[jim829]

Because the method is in SingleRoomInfo not SingleRoomPanel.
