*/
public class 帮助信息 extends JDialog{
JPanel panel1 = new JPanel();
JLabel jLabel1 = new JLabel();
JLabel jLabel2 = new JLabel();

GridLayout gridLayout1 = new GridLayout();
/** Creates a new instance of 帮助信息 */
public 帮助信息() {
super(new Frame(),"游戏信息",false);
setSize(300,100);
panel1.setLayout(gridLayout1);
jLabel1.setText("汉诺塔小游戏程序1.0版本，谢谢支持");
jLabel2.setText("作者：....");
gridLayout1.setColumns(1);
gridLayout1.setRows(2);
panel1.add(jLabel1,null);
panel1.add(jLabel2);
getContentPane().add(panel1);
