Passing JLabels between classes

Hi,

I'm trying to have multiple classes to complete a goal. I need multiple classes to access one JLabel and update it using the .setText() function. I have a variables class that just holds variables. this is its code:

Code:

---

import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.Timer;

public class variables {
       
        public static String bUrl;
        public static String username;
        public static String votingip;
        public static int vote_count;
   
        public JFrame frame = new JFrame();
    public JLabel label = new JLabel ();
    public JLabel userlabel= new JLabel ();
    public JLabel iplabel = new JLabel ();
    public JLabel timerheadinglabel = new JLabel ();
    public JLabel votecountlabel = new JLabel ();
    public JLabel lastvoteinfolabel = new JLabel ();
    public JLabel totaltallylabel = new JLabel ();
    public JPanel panel = new JPanel();
}
}

---

Now I have a class that accesses these to apply values and attributes as normal and it displays the JFrame.

Code:

---

import javax.swing.JFrame;

import back_end.variables;

public class label_set {
       
        variables call_vars = new variables();
       
       
        public void addMainResultsWindow(){
               
                call_vars.frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                call_vars.frame.setSize(480, 250);
           
            call_vars.panel.setLayout(null);
               
            call_vars.timerheadinglabel.setText("Time till next vote:");
            call_vars.votecountlabel.setText("Waiting");
            call_vars.label.setText("Waiting");
            call_vars.iplabel.setText("Waiting");
            call_vars.userlabel.setText("Waiting");
            call_vars.lastvoteinfolabel.setText("Last Vote Info");
            call_vars.totaltallylabel.setText("Total Tally");

            call_vars.timerheadinglabel.setBounds(175, 47, 150, 14);
            call_vars.label.setBounds(214, 70, 60, 14);
            call_vars.iplabel.setBounds(90, 125, 150, 14);
            call_vars.userlabel.setBounds(90, 150, 120, 14);
            call_vars.votecountlabel.setBounds(250, 125, 100, 20);
            call_vars.lastvoteinfolabel.setBounds(95, 100, 100, 14);
            call_vars.totaltallylabel.setBounds(250, 100, 100, 14);
               
            call_vars.panel.add(call_vars.label);
            call_vars.panel.add(call_vars.timerheadinglabel);
            call_vars.panel.add(call_vars.userlabel);
            call_vars.panel.add(call_vars.iplabel);
            call_vars.panel.add(call_vars.votecountlabel);
            call_vars.panel.add(call_vars.lastvoteinfolabel);
            call_vars.panel.add(call_vars.totaltallylabel);
           
            //this item echos out the first line in the console
            System.out.println(call_vars.userlabel);

            call_vars.frame.add(call_vars.panel);
            call_vars.frame.setVisible(true);
        }
}

---

Then once this is done i try and have the main class that runs this all print the call_vars.userlabel variable, the iteresting this is its not the same as the call in the label_set class. so that class is not updating the variable in the variiables class like i want it too. here is the main calss that excutes this:

Code:

---

import back_end.variables;
import GUI_components.label_set;

public class start_gui_bot {
       
        variables call_vars = new variables();
       
        public void startGuiBot (String url) throws Exception {
               
                variables.bUrl = url;
                call_vars.timeRemaining = variables.timertime;
               
        }

public static void main(String[] args) throws Exception {
       
        start_gui_bot vb = new start_gui_bot ();
        label_set ls = new label_set();
        variables call_vars = new variables();
               
                vb.startGuiBot(variables.form_url);
                ls.addMainResultsWindow();

                //this is the se3cond output in the console
                System.out.println(call_vars.userlabel);

                call_vars.label.setText("Done!");
            }
        }

---

and this all out puts:

javax.swing.JLabel[,90,150,120x14,invalid,alignmentX=0.0,alignmentY=0 .0,border=,flags=8388608,maximumSize=,minimumSize= ,preferredSize=,defaultIcon=,disabledIcon=,horizon talAlignment=LEADING,horizontalTextPosition=TRAILI NG,iconTextGap=4,labelFor=,text=Waiting,verticalAl ignment=CENTER,verticalTextPosition=CENTER]
javax.swing.JLabel[,0,0,0x0,invalid,alignmentX=0.0,alignmentY=0.0,bor der=,flags=8388608,maximumSize=,minimumSize=,prefe rredSize=,defaultIcon=,disabledIcon=,horizontalAli gnment=LEADING,horizontalTextPosition=TRAILING,ico nTextGap=4,labelFor=,text=,verticalAlignment=CENTE R,verticalTextPosition=CENTER]

in the console when the main class runs. So my question is how can i get the addMainResultsWindow(); method to change the variables in the variables.java class?

Your "out puts" is simply the toString() representation of a JLabel, and should be the expected output given your trying to call println on a JLabel rather than its text.

More importantly, your design is very un-OOPish and is liable to break. I urge you to study a book on OOP (it doesn't have to be OOP as it applies to Java, but that would help too) before trying to create complex Java GUI's.
