                break;
            }
        }
    } catch (ClassNotFoundException ex) {
        java.util.logging.Logger.getLogger(Music.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
    } catch (InstantiationException ex) {

    }
    //</editor-fold>

    /* Create and display the form */
    java.awt.EventQueue.invokeLater(new Runnable() {
        @Override
        public void run() {
            //new Music().setVisible(true);
        }
    });
}

private class Start implements Runnable {

    @Override
    public void run() {
        for (int x = 0; x < 101; x++) {
            ProgressBar.setValue(x);
            ProgressBar.repaint();
            try {
                Thread.sleep(50);
            } catch (Exception ex) {
            }
        }
    }
}

This is a lot fo code. Can you boil it down to a minimal example that demonstrates the problem? For example, none of the look-and-feel or window centering stuff seems directly relevant. — Mike Samuel, Mar 04 '13 at 21:12

@user2133393: It's OK to cross-post, but if you do, please have the decency to let us know up front so we can check out all cross-posts before answering. It can upset us as you can imagine, if we answer a question and find that it's been already answered elsewhere. Most of us greatly appreciate it if you show some respect for our right to our free time. — Hovercraft Full Of Eels, Mar 04 '13 at 22:18
_Im just searching some fast answer i cant wait_ in that case, your best option is to hire a consultant - s/he'll be at your service and do all _your_ work immediately (provided the payment is good enough ;-) — kleopatra, Mar 05 '13 at 11:36

You may be looking for ProgressMonitorInputStream. There 's a discussion in How to Use Progress Monitors, and an example in ProgressMonitorDemo.
