Having problems with Thread

[bozovilla]

I am unable to get the Thread working in my code which is used to do a count down from 25 to 0. From my testing using a System.out.println: Only font and paint appear on the command console. CAn anyone help?

Here is my code:


import java.awt.*;
import javax.swing.*;
import java.awt.event.*;

public class Spaceship extends JFrame{

private JPanel displayP, radarP, rowsP, speedMeterP, messageP;//, controlsP;
private JLabel display, radar, rows, speedMeter, message;

//private JButton jbtnCake1, jbtnCake2, jbtnCake3,
// jbtnCoffee1, jbtnCoffee2, jbtnCoffee3;

//private JTextArea jta;
Count counter= new Count();

public static void main(String[] args){

Spaceship f=new Spaceship();
f.setVisible(true);
}//end of main

public Spaceship()
{

setSize(500,500);
setTitle("Spaceship");
setDefaultCloseOperation(EXIT_ON_CLOSE);
//getContentPane().setLayout(new BorderLayout());

Container container = getContentPane();
container.setLayout(new BorderLayout());

displayP=new JPanel();

display = new JLabel("display");
displayP.add(display);
container.add(displayP, BorderLayout.NORTH);

radarP=new JPanel();
radar= new JLabel("radar");
radarP.add(radar);
container.add(radarP, BorderLayout.WEST);

rowsP =new JPanel();
rows= new JLabel("rows");
rowsP.add(rows);
container.add(rowsP, BorderLayout.CENTER);

speedMeterP =new JPanel();
speedMeter= new JLabel("speedmeter");
speedMeterP.add(speedMeter);
container.add(speedMeterP, BorderLayout.EAST);

messageP =new JPanel();
message= new JLabel("message");
messageP.add(message);
container.add(counter, BorderLayout.SOUTH);

}//end of constructor
}

class Count extends JPanel implements Runnable {

Thread t;int i=0;
Font font;

public Count()
{
System.out.println("font");

font=new Font("TimesNewRoman",font.ITALIC,28);

}

public void start()
{System.out.println("start");

t=new Thread(this);
t.start();

}

public void run()
{
System.out.println("run");

for(i=25;i>=0;i--)//countdown
{
try
{
Thread.sleep(1000);
System.out.println(i);
}
catch(Exception e)
{
System.out.println(e);
}
}

repaint();

}//end of run

public void paint(Graphics g)
{
System.out.println("paint");
g.setColor(Color.red);//COUNTDOWN STOP
g.setFont(font);
g.drawString(""+i,50,50);

}

}

What should appear? Can you explain what you expect to see?

[bozovilla]

Do you see that I have a thread to start and run? If the program actually runs them, it should appear font, start, run ant paint on the console. Thanks

What does appear? Copy the output of the program here. It would help if you put it all in one post. One part of the post says what is output and another later part what you want to see. Having them together would make it easier to see your problem.

Where do you call the methods that are supposed to output what you want to see?

Hmmm, you never start your thread...

Put

Code:

counter.start()

after (for example)

Code:

container.add(counter, BorderLayout.SOUTH);
