Java:GridLayout开头的间隙

我正在尝试用Java编写一个游戏，目前正在制作标题屏幕

我想中间有三个按钮放在中间。 这些按钮是“播放”、“选项”和“退出”

我使用网格布局订购按钮，现在我希望屏幕顶部和播放按钮之间有一点间隙。你能告诉我怎么做吗

我当前的代码如下所示：

public class GamePanel extends JPanel {

    private JPanel optionsPanel;

    public GamePanel() {
        super(new FlowLayout());
        FlowLayout layout = (FlowLayout) getLayout();
        layout.setAlignment(FlowLayout.CENTER);

        GridLayout layout2 = new GridLayout(3,1);
        optionsPanel = new JPanel(layout2);
        add(optionsPanel);

        optionsPanel.add(new CustomButton("Play"));
        optionsPanel.add(new CustomButton("Options"));
        optionsPanel.add(new CustomButton("Quit"));
    }
}

optionsPanel.setBorder(BorderFactory.createEmptyBorder(10, 0, 0, 0));

试着这样做：

public class GamePanel extends JPanel {

    private JPanel optionsPanel;

    public GamePanel() {
        super(new FlowLayout());
        FlowLayout layout = (FlowLayout) getLayout();
        layout.setAlignment(FlowLayout.CENTER);

        GridLayout layout2 = new GridLayout(3,1);
        optionsPanel = new JPanel(layout2);
        add(optionsPanel);

        optionsPanel.add(new CustomButton("Play"));
        optionsPanel.add(new CustomButton("Options"));
        optionsPanel.add(new CustomButton("Quit"));
    }
}

optionsPanel.setBorder(BorderFactory.createEmptyBorder(10, 0, 0, 0));
