The method you want is: setLocationRelativeTo()

Adding it with null to the JFrame, will center it on the screen. Adding the JFrame to the dialog will center it on the jframe.

import javax.swing.JDialog;
import javax.swing.JFrame;

public class Centered
{
    public static void main( String args[] )
    {
        JFrame jFrame = new JFrame();

        jFrame.setSize( 250 , 250 );
        jFrame.setLocationRelativeTo( null );
        jFrame.setVisible( true );

        JDialog jDialog = new JDialog();
        jDialog.setLocationRelativeTo( jFrame );
        jDialog.setVisible( true );
    }
}
