Follow these steps:
1. Get the placement and dimensions of the Frame:
Rectangle rectFrame = myFrame.bounds();
The x and y members of rectFrame is the upper-left corner of the Frame on
the screen. The width and height members, obviously, are the dimensions of the
Frame.
2. Get the dimensions of the Dialog:
Dimension dimDialog = myDialog.size();
3. Center the Dialog over the Frame:
dimDialog.move(rectFrame.x+(rectFrame.width/2) -(rectDialog.width/2),
rectFrame.y+(rectFrame.height/2)-(rectDialog.height/2));
>2. How do I center a Frame on the Screen?
The screen dimensions are available from the Toolkit:
Dimension dimDesktop = Toolkit.getDefaultToolkit().getScreenSize();
To center the Frame:
Dimension dimFrame = myFrame.size();
myFrame.move(dimDesktop.width/2 - dimFrame.width/2,
dimDesktop.height/2 - dimFrame.height/2);

The point (512, 384) indicates the upper-left corner of the Frame, which would
place the upper-left corner of the Frame at the center of the desktop, but won't
center the frame over the desktop. (See above)
