This Java demostrates a way of removing the title bar and other decorations from a frame. A frame without decorations looks and behaves like a Window container. However, if the developer does not want the frame with all the decorations, it is better to use a Window container. Further, the decorations can only be removed while the frame is not visible.

 Frame applicationframe = new Frame();
    applicationframe.setUndecorated(true);
    
    // Confirm the current decorated state
    boolean undecorated = applicationframe.isUndecorated();
