public class InventoryServer extends JFrame {
 
    private Toolkit toolkit;
    private Dimension windowSize;
    private JPanel panelSample;
    private Image icon;
 
    public InventoryServer() {
 
        toolkit = Toolkit.getDefaultToolkit();
        icon = new ImageIcon("c:/pics/mercuryLogo.jpg").getImage().getScaledInstance(300, 300, 0);
        windowSize = toolkit.getScreenSize();
        panelSample = new JPanel();
    }
 
    public void setComponents(Container cont) {
 
 
    }
 
    public void initializeServer() {
 
        this.setLocationByPlatform(true);
        this.setIconImage(icon);
        this.setTitle("Inventory Server");
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        this.setComponents(this.getContentPane());
        this.setBounds(0, 0, 400, 500);
        this.setVisible(true);
    }
 
    public static void main(String[] args) {
 
        SwingUtilities.invokeLater(new Runnable() {
 
            InventoryServer iS = new InventoryServer();
 
            public void run() {
 
                iS.initializeServer();
            }
        });
    }
}

ahmm world... how bout this.. method..

setLocationRelativeTo(null)... when i used this one... its makes the frame centered in the monitor screen...?

is this fine...?

Definitely... using the method setLocationRelativeTo(null) will set the position of your frame at the center.
