在软件开发中，有一种UI交互组件为对话框，用于和用户进行某些确认信息的交互，比如：警告信息、提示信息、确认信息等交互功能。在某个软件系统中，开发者把对话框组件命名为Dialog，经过产品需求分析和功能分析。现发现：对话框（Dialog）包含的内容可以包括：图标、标题、提示内容、确认按钮、取消按钮，关闭按钮等6个内容组成。在具体编程使用时，用户可以根据自己的需求，创建出符合自己需要的对话框。 请结合自己所学的设计模式内容，采用合理的设计模式完成上述需求，画出对应的设计模式的类图，并使用Java代码完成编码实践，

根据上述需求，可以采用建造者模式来构建对话框组件，该模式可以将复杂对象的构建过程和表示分离开来，使得同样的构建过程可以创建不同的表示。

对话框组件的建造者类：

public class DialogBuilder {
    private ImageIcon icon;
    private String title;
    private String message;
    private ActionListener confirmListener;
    private ActionListener cancelListener;
    private ActionListener closeListener;

    public DialogBuilder setIcon(ImageIcon icon) {
        this.icon = icon;
        return this;
    }

    public DialogBuilder setTitle(String title) {
        this.title = title;
        return this;
    }

    public DialogBuilder setMessage(String message) {
        this.message = message;
        return this;
    }

    public DialogBuilder setConfirmListener(ActionListener listener) {
        this.confirmListener = listener;
        return this;
    }

    public DialogBuilder setCancelListener(ActionListener listener) {
        this.cancelListener = listener;
        return this;
    }

    public DialogBuilder setCloseListener(ActionListener listener) {
        this.closeListener = listener;
        return this;
    }

    public Dialog build() {
        return new Dialog(icon, title, message, confirmListener, cancelListener, closeListener);
    }
}

对话框组件类：

public class Dialog extends JDialog {
    private JLabel iconLabel;
    private JLabel titleLabel;
    private JLabel messageLabel;
    private JButton confirmButton;
    private JButton cancelButton;
    private JButton closeButton;

    public Dialog(ImageIcon icon, String title, String message,
                  ActionListener confirmListener, ActionListener cancelListener, ActionListener closeListener) {
        setModal(true);
        setResizable(false);
        setDefaultCloseOperation(DISPOSE_ON_CLOSE);
        setSize(300, 200);
        setLocationRelativeTo(null);

        setIcon(icon);
        setTitle(title);
        setMessage(message);
        setConfirmListener(confirmListener);
        setCancelListener(cancelListener);
        setCloseListener(closeListener);

        JPanel panel = new JPanel();
        panel.setLayout(new GridBagLayout());
        GridBagConstraints c = new GridBagConstraints();

        c.gridx = 0;
        c.gridy = 0;
        c.gridwidth = 1;
        c.gridheight = 1;
        c.insets = new Insets(10, 10, 10, 10);
        c.anchor = GridBagConstraints.CENTER;
        iconLabel = new JLabel();
        panel.add(iconLabel, c);

        c.gridwidth = 1;
        c.gridheight = 1;
        c.insets = new Insets(10, 10, 10, 10);
        c.anchor = GridBagConstraints.CENTER;
        cancelButton = new JButton("取消");
        panel.add(cancelButton, c);

        c.gridx = 2;
        c.gridy = 2;
        c.gridwidth = 1;

        c.anchor = GridBagConstraints.CENTER;
        closeButton = new JButton("关闭");
        panel.add(closeButton, c);

        setContentPane(panel);
    }

    public void setIcon(ImageIcon icon) {
        if (icon != null) {
            iconLabel.setIcon(icon);
        }
    }

    public void setTitle(String title) {
        if (title != null) {
            titleLabel.setText(title);
        }
    }

    public void setMessage(String message) {
        if (message != null) {
            messageLabel.setText(message);
        }
    }

    public void setConfirmListener(ActionListener listener) {
        if (listener != null) {
            confirmButton.addActionListener(listener);
        }
    }

    public void setCancelListener(ActionListener listener) {
        if (listener != null) {
            cancelButton.addActionListener(listener);
        }
    }

    public void setCloseListener(ActionListener listener) {
        if (listener != null) {
            closeButton.addActionListener(listener);
        }
    }
}

使用示例：

Dialog dialog = new DialogBuilder()
        .setIcon(new ImageIcon("icon.png"))
        .setTitle("标题")
        .setMessage("提示内容")
        .setConfirmListener(e -> {
            // 确认按钮点击事件处理
            dialog.dispose();
        })
        .setCancelListener(e -> {
            // 取消按钮点击事件处理
            dialog.dispose();
        })
        .setCloseListener(e -> {
            // 关闭按钮点击事件处理
            dialog.dispose();
        })
        .build();
dialog.setVisible(true);
