How to save a minimized inner frame on top

I have four internal frames and 3 buttons in it. When I click the maximize button, it maximizes, but overlaps all frames. But I believe that it should show minimized frames. please find the code below

  package Project;

You can try: JDesktopPane#setComponentZOrder(Component com, int i). In accordance with the documents :

z-order . Z- , ; z- z-. , z- z-.

...

:

z- removeNotify. , , .

JInternalFrame, JDesktopPane.

UPDATE:

:

, , , , JDesktopPane#setComponentZOrder(Component com, int i) JInternalFrame . ,

:

, JInternalFrame:

    jb2.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent ae) {
            try {
                if (jInternalFrame.isMaximum()) {//restore
                    jInternalFrame.pack();
                } else {//maximize
                    jInternalFrame.setMaximum(true);
                }
                jdp.remove(jInternalFrame);
                jdp.add(jInternalFrame, JDesktopPane.FRAME_CONTENT_LAYER);
                jdp.revalidate();
                jdp.repaint();
            } catch (Exception e) {
                e.printStackTrace();
            }

        }
    });

DEFAULT_LAYER, :

    jb.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent ae) {
            try {
                if (jInternalFrame.getLayer() == JDesktopPane.FRAME_CONTENT_LAYER) {
                    jdp.remove(jInternalFrame);
                    jdp.add(jInternalFrame, JDesktopPane.DEFAULT_LAYER);
                    jdp.revalidate();
                    jdp.repaint();
                }
                jInternalFrame.pack();
                jInternalFrame.setIcon(true);
            } catch (PropertyVetoException ex) {
