What is the purpose of this code

private void searchButActionPerformed(java.awt.event.ActionEven t evt) {

this is a buttion that supposed to do search on the net(when this buttion clicked the application started to work).I just want to see the bar.
the implimintation of the bar is a thread

ublic class threadProcessBar implements Runnable {
      
public Boolean done;
public  long interval=1000;
      
 
         public void run() {
             System.out.print("thread Process Bar started ");
             done=false;
             start.jProgressBar1.setVisible(true);  
            start.jProgressBar1.setIndeterminate(true);
            start.jProgressBar1.setString("Loading");
            start.jProgressBar1.repaint();

            while(!done)
            {
            try {
                Thread.sleep(interval) ;
            } catch (InterruptedException ex) {
           
            }
            }
            start.jProgressBar1.setValue(100);
            start.jProgressBar1.setIndeterminate(false);
            start.jProgressBar1.setString("Done");
            start.jProgressBar1.repaint();
         }
     }

when the app is comlete then done=true.
I can see the bar only when message pop up from searchButActionPerformed then it appeared.
I tested it and only if I do JOptionPane.showMessageDialog(null, "start");
and then start.jProgressBar1.setVisible(true); its work but without the message it dosent work. Why is that?
