Method

PointcenterPoint(int width, int height, JFrame frame)
center Point 
Point point = null;
Dimension frameSize = frame.getSize();
Point framePoint = frame.getLocation();
point = new Point(framePoint.x + (frameSize.width / 2) - (width / 2),
        framePoint.y + (frameSize.height / 2) - (height / 2));
return point;
voidcenterPosition(JFrame invokerFrame, Window w, int width, int height)
center Position 
int x = invokerFrame.getX() + (invokerFrame.getWidth() - width) / 2;
int y = invokerFrame.getY() + (invokerFrame.getHeight() - height) / 2;
w.setBounds(x, y, width, height);
voidcenterWindow(JFrame frame)
center Window 
Toolkit tk = Toolkit.getDefaultToolkit();
Dimension screenSize = tk.getScreenSize();
int screenHeight = screenSize.height;

Dimension frameSize = frame.getSize();
if (frameSize.height > screenSize.height) {
    frameSize.height = screenSize.height;
if (frameSize.width > screenSize.width) {
    frameSize.width = screenSize.width;
frame.setLocation((screenSize.width - frameSize.width) / 2, (screenSize.height - frameSize.height) / 2);
voidcenterWindow(JFrame frame)
Move frame to center of current screen 
Point centerPoint = GraphicsEnvironment.getLocalGraphicsEnvironment().getCenterPoint();
