JAVA程序可以通过编译，但是运行时报错NoSuchMethodError，求解！

public class pandacount3 extends JFrame{
ArrayList<JLabel> panda;
JPanel a,b,c;
JLabel q;
JTextField t;
JButton check;
ImageIcon img;
ActionListener listener;
int i,max;
public pandacount3(){
a = new JPanel();
img = new ImageIcon("panda.jpg");
panda = new ArrayList<JLabel>();
a.setLayout(new GridLayout(0,5));
for(i=0; i<max; i++){
panda.add(new JLabel(img));
a.add(panda.get(i));
}
b = new JPanel();
t = new JTextField(2);
q = new JLabel("How many Pandas can you see?");
b.add(q);
b.add(t);
c = new JPanel();
check = new JButton("Check!");
c.add(check);
add(a, BorderLayout.NORTH);
add(b, BorderLayout.CENTER);
add(c, BorderLayout.SOUTH);
listener = new Listener();
check.addActionListener(listener);

}
public void main(String Args[]){
max = Integer.parseInt(Args[0]);
pandacount3 f = new pandacount3();
f.setTitle("Welcome to PandaLand!");
f.setLocationRelativeTo(null);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setSize(400,300);
f.setVisible(true);
}
public class Listener implements ActionListener{
public void actionPerformed(ActionEvent event){
if((t.getText())!=null){
int j = Integer.parseInt(t.getText());
if(j==i){
q.setText("Correct! How many Pandas can you see now?");
a.removeAll();
i = (int)(Math.random()*max+1);
for(int k = 0;k<i;k++){
a.add(panda.get(k));
}
a.updateUI();
}
else{q.setText("Wrong! Try again!");}
}
}
}
}
我按 3楼的方法改了 还是编译通过 运行不了
