Java Programming

Hi, can anyone help me with this code, I'm trying to apply a selected number from 0 to 10000 from the countdown prog to the ddd program and countdown from that number.

I can compile, but the program crashs after chosing a number.

import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.DefaultListModel;
import javax.swing.JList;
import javax.swing.JScrollPane;
import java.util.*;
import javax.swing.*;
import javax.swing.event.*;
import java.awt.*;
import java.awt.event.*;
import java.io.*;
import java.math.*;

public class CountDown extends JPanel
{
  JList list;
  DefaultListModel model;
  int counter = 10000;
  String time;
  final int SECONDS = 60;
  int minutes = 0;
  public static void main(String s[])
  {
      JFrame frame = new JFrame("List Model Example");
      frame.setContentPane(new CountDown());
      frame.setSize(70, 80);
      frame.setVisible(true);
  }
  public CountDown()
  {
    setLayout(new BorderLayout());
    model = new DefaultListModel();
    list = new JList(model);
    JScrollPane pane = new JScrollPane(list);
    pane.setPreferredSize(new Dimension(50,22));
    JButton btn = new JButton("Min");
    for (int i = 1; i < 10000; i++)
    model.addElement(" " + i);
    list.setSelectedIndex(0);
    add(pane, BorderLayout.NORTH);
    add(btn, BorderLayout.WEST);
    btn.addActionListener(new ActionListener()
	{
		public void actionPerformed(ActionEvent ae)
	 	{
			int bob = list.getSelectedIndex();
			if(bob == JOptionPane.OK_OPTION);
			{
			    String time = (String)list.getSelectedValue();
			    System.out.println("Chosen Minute" + time);
			    ddd("");
			}
		}
	});
 }
 public void ddd(String time)
 {
	minutes = Integer.parseInt(time);
	final java.util.Timer sid = new java.util.Timer();
	sid.scheduleAtFixedRate(new TimerTask()
	{
	   int bbb = minutes * SECONDS;
	   public void run()
	   {
	     	System.out.println(""+bbb/SECONDS+" : "+bbb % SECONDS);
	   		bbb--;
	        if(bbb < 0)
	        {
	    	    sid.cancel();
	   		    System.exit(0);
	        }
	   }
    },0,1000);

  }
}
