这是用Java程序编的一个配对游戏但怎么修改程序才能使游戏运行

public class lianxi8 extends JFrame implements MouseListener,MouseMotionListener{
public static void main(String[] args) {
private static final boolean fasle = false;
private JLabel img[]=new JLabel[5];
private JLabel targets[]=new JLabel[5];

public lianxi8(){
super("简易配对游戏");
this.setLayout(new BorderLayout());
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
final JPanel imagePanel=new JPanel();
imagePanel.setLayout(null);
imagePanel.setOpaque(false);
setGlassPane(imagePanel);
getGlassPane().setVisible(true);

icon[1]=new ImageIcon(getClass().getResource("xianshiqi.png"));
icon[2]=new ImageIcon(getClass().getResource("xiyiji.png"));
icon[3]=new ImageIcon(getClass().getResource("yifu.png"));
icon[4]=new ImageIcon(getClass().getResource("zixingche.png"));
final JPanel bottomPanel=new JPanel();
bottomPanel.setLayout(new FlowLayout(FlowLayout.CENTER,20,5));
this.add(bottomPanel,BorderLayout.SOUTH);
for(int i=0;i<5;i++){
img[i]=new JLabel(icon[i]);
img[i].setSize(600,600);

imagePanel.add(img[i]);

targets[i]=new JLabel();
targets[i].setOpaque(true);
targets[i].setBackground(Color.BLUE);

}
targets[0].setText("咖啡");

语法错误了，不要把其它方法放入main方法中。
