如何让水平JScrollBar的默认位置在右侧？

我正在开发一个程序，默认情况下水平滚动条应该位于右侧位置，我尝试使用 Viewport() 但它不起作用。有什么想法吗？

jScrollPane4.getViewport().setViewPosition(new Point(10, 10));
BoxLayout boxlayout = new BoxLayout(categoryPanel, BoxLayout.Y_AXIS);
BoxLayout boxlayout2 = new BoxLayout(servicePanel, BoxLayout.Y_AXIS);
categoryPanel.setLayout(boxlayout);
category cg = new category();
subString ss = new subString();
try {
    List<JButton> buttonList = new ArrayList<>();
    List<Category> map = cg.readDatafromJson();
    for (Category item : map) {
        String CAr = ss.SubString(item.getName_ar());
        String SAr = ss.SubString(item.getName_en());
        JButton button = new JButton("<html><p style=\"text-align:right;\"><b>" + CAr + "</b> \n" + SAr + "</P></html>", icon);
        Border line = new LineBorder(Color.BLACK);
        button.setActionCommand(item.getKey());
        button.setHorizontalAlignment(SwingConstants.RIGHT);
        button.setComponentOrientation(ComponentOrientation.RIGHT_TO_LEFT);
        buttonList.add(button);
        categoryPanel.add(button);
        categoryPanel.revalidate();
        categoryPanel.repaint();
    }
} catch (IOException ex) {
    Logger.getLogger(PassOrdreCashier.class.getName()).log(Level.SEVERE, null, ex);
}

I have a program I am working on, the horizontal scrollbar should be in the right-hand position by default, I tried to use Viewport() but it doesn't work. Any ideas?

jScrollPane4.getViewport().setViewPosition(new Point(10, 10));
BoxLayout boxlayout = new BoxLayout(categoryPanel, BoxLayout.Y_AXIS);
BoxLayout boxlayout2 = new BoxLayout(servicePanel, BoxLayout.Y_AXIS);
categoryPanel.setLayout(boxlayout);
category cg = new category();
subString ss = new subString();
try {
    List<JButton> buttonList = new ArrayList<>();
    List<Category> map = cg.readDatafromJson();
    for (Category item : map) {
        String CAr = ss.SubString(item.getName_ar());
        String SAr = ss.SubString(item.getName_en());
        JButton button = new JButton("<html><p style=\"text-align:right;\"><b>" + CAr + "</b> \n" + SAr + "</P></html>", icon);
        Border line = new LineBorder(Color.BLACK);
        button.setActionCommand(item.getKey());
        button.setHorizontalAlignment(SwingConstants.RIGHT);
        button.setComponentOrientation(ComponentOrientation.RIGHT_TO_LEFT);
        buttonList.add(button);
        categoryPanel.add(button);
        categoryPanel.revalidate();
        categoryPanel.repaint();
    }
} catch (IOException ex) {
    Logger.getLogger(PassOrdreCashier.class.getName()).log(Level.SEVERE, null, ex);
}
