下面是我总结Java swing 常用的弹出框工具类：
Java代码
- 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);
- }
- }
