java swing 提示框工具类

下面是我总结java  swing 常用的弹出框工具类:

package com.swing.messagebox;

import javax.swing.JOptionPane;

public class GUIUtil23
{
    public static final String MESSAGE_WARNING     = " 警告";
    public static final String MESSAGE_INFORMATION = " 消息";
    public static final String MESSAGE_ERROR = " 错误";

    private GUIUtil23()
    {
        throw new Error("Don't let anyone instantiate this class.");
    }
    
    /***
     * Warning boxes
     * 
     * @param mesg
     */
    public static void warningDialog(String mesg)
    {
        JOptionPane
                .showMessageDialog(
                    null,
                    "<html><font color=\"yellow\"  style=\"font-weight:bold;" +
                    "background-color:#666666\" >"
                        + mesg + "</font></html>", MESSAGE_WARNING,
                    JOptionPane.WARNING_MESSAGE);
    }

    /***
     * error
     * 
     * @param mesg
     */
    public static void errorDialog(String mesg)
    {
        JOptionPane
                .showMessageDialog(
                    null,
                    "<html><font color=\"red\"  style=\"font-weight:bold;" +
                    "background-color:white\" >"
                        + mesg + "</font></html>", MESSAGE_ERROR,
                    JOptionPane.ERROR_MESSAGE);
    }

    /***
     * information
     * 
     * @param mesg
     */
    public static void infoDialog(String mesg)
    {
        JOptionPane.showMessageDialog(null,
            "<html><font color=\"green\"  style=\"font-weight:bold;\" >" + mesg
                + "</font></html>", MESSAGE_INFORMATION,
            JOptionPane.INFORMATION_MESSAGE);
    }
}
