What resize and move utility does is, it allows you to drag or resize your undecorated JFrame. So here is how to use it.

 private static void resizeMoveFrame(JFrame frame) {
     //Resize and move
     SwingUtilities.invokeLater(() -> {

         //Drag around your frame using below

         ComponentMoverUtil.moveFrame(frame, false, frame.getComponents());

        // Use below if you want to resize your frame
         ComponentResizerUtil cr = new ComponentResizerUtil();
         frame.getRootPane().setBorder(new LineBorder(Color.gray));
         cr.setSnapSize(new Dimension(5, 5));
         cr.setDragInsets(new Insets(5, 5, 5, 5));
       
         //always register frame to resize
         cr.registerComponent(frame); 

     });
 }
