如何在showOptionDialog中对齐/居中文本

import javax.swing.*;

public class DialogAlignmentExample {

    public static void main(String[] args) {
        // 创建选项数组和消息文本
        Object[] options = {"Option 1", "Option 2", "Option 3"};
        String message = "This is a message with aligned/centered text.";

        // 创建一个JPanel对象，并设置布局管理器
        JPanel panel = new JPanel();
        panel.setLayout(new FlowLayout(FlowLayout.CENTER)); // 居中对齐

        // 创建消息文本所在的组件，并添加到JPanel对象中
        JLabel label = new JLabel(message);
        panel.add(label);

        // 创建JOptionPane对象，并设置布局管理器
        JOptionPane optionPane = new JOptionPane(panel, JOptionPane.PLAIN_MESSAGE, JOptionPane.DEFAULT_OPTION, null, options, options[0]);
        optionPane.setLayout(new FlowLayout(FlowLayout.CENTER)); // 居中对齐

        // 显示对话框
        JDialog dialog = optionPane.createDialog(null, "Dialog Title");
        dialog.setVisible(true);

        // 获取用户选择的选项
        Object selectedValue = optionPane.getValue();
        if (selectedValue != null) {
            int selectedOption = JOptionPane.YES_OPTION;
            for (int i = 0; i < options.length; i++) {
                if (options[i].equals(selectedValue)) {
                    selectedOption = i;
                    break;
                }
            }
            System.out.println("Selected Option: " + selectedOption);
        }
    }
}
