我正在编写一个生成随机迷宫的代码，每次运行程序时它看起来都不同，但我不能让我的重置按钮工作。以下是我的一些代码：
public class MakeFrame extends JPanel implements ActionListener {
JFrame frame;
JPanel buttonPanel;
JButton solve1;
JButton solve2;
JButton solve3;
JButton clear;
JButton reset;
Maze maze = new Maze();
void buildframe() {
frame = new JFrame("maze"); //makes a frame, names it maze
frame.add(this, BorderLayout.CENTER);
frame.add(maze);
buttonPanel = new JPanel();
frame.add(buttonPanel, BorderLayout.NORTH);
solve1 = new JButton("solve 1"); // create some buttons
solve2 = new JButton("solve 2");
solve3 = new JButton("solve 3");
clear = new JButton("clear");
reset = new JButton("reset");
buttonPanel.add(solve1); // add the buttons to a panel
buttonPanel.add(solve2);
buttonPanel.add(solve3);
buttonPanel.add(clear);
buttonPanel.add(reset);
solve1.addActionListener(this);// assigns action listeners to buttons
solve2.addActionListener(this);
solve3.addActionListener(this);
clear.addActionListener(this);
reset.addActionListener(this);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); // makes the frame visable, grey and close on exit.
frame.setSize(455, 320);
frame.setVisible(true);
setBackground(Color.GRAY);
}
@Override
public void actionPerformed(ActionEvent e) {
if (e.getSource() == reset) {
frame.add(new Maze());
repaint();
}
}
}
我不知道在动作执行的方法中放入什么来使其发挥作用，有人可以帮助我吗？
这是我的课堂迷宫：

这是我的班级单元格：p
public class Cell {
private String cell;
Cell(String type){
if (type.equals("walls")){
walls();
}
if (type.equals("floor")){
Floor();
}
if (type.equals("start")){
start();
}
if(type.equals("end")){
end();
}
}
void walls(){
cell = "#";
}
void start(){
cell = "S";
}
void end(){
cell = "E";
}
void Floor(){
cell = " ";
}
public String getType(){
return cell;
}
}

你有太多的这个
<div class="header">
<img class="banner" src="//notrealdomain1.com/banner.png">
</div>
/* All in one selector */
.banner {
display: block;
-moz-box-sizing: border-box;
box-sizing: border-box;
background: url(http://notrealdomain2.com/newbanner.png) no-repeat;
width: 180px; /* Width of new image */
height: 236px; /* Height of new image */
padding-left: 180px; /* Equal to width of new image */
}
哪个会生成另一个JPanel，但我找不到任何运行整个代码的主要方法，所以在这里你去，享受xD
