I have a main class called Mclass.java, from this call am calling a thread which is in SimpleThread.java , and also creating an object for Taskframe.java the TaskFrame.java contions panels
From the SimpleThread.java am getting current time, and I want to display the time in any of the panel , how can I do that ? I mean I want the label name is current system time
JLabel currentsystem time = new JLabel(new java.util.Date(System.currentTimeMillis()).toString())
add this to your panel, from your run of your thread set the text of that each time

Your description of the problem makes no sense...
Post your code, remembering to use the code formatting tags, which demonstrates the incorrect behaviour
I Thanks for your response, This is my problem, How can I bring current (Dynamic time) in Delpan.java (Panel)
Main.java
public static void main(String[] args) {
// TODO Auto-generated method stub
new SimpleThread().start();
Delpan delp = new Delpan();
}
}
SimpleThread.java
class SimpleThread extends Thread {
Delpan del = new Delpan();
public SimpleThread() {
super();
}
public String cur_time;
Calendar cal = Calendar.getInstance(TimeZone.getDefault());
public void run() {
while(true)
{
Calendar cal = Calendar.getInstance(TimeZone.getDefault());
cur_time = String.valueOf(cal.getTime());
try {
sleep(1000);
} catch (InterruptedException ie) {System.out.println("Exception"+ie);}
System.out.println("Time Dispaly "+cur_time);
}
}
}
Delpan.java
public class Delpan extends JPanel {
private static final long serialVersionUID = 1L;
public Delpan() {
super();
initialize();
}
private void initialize() {
JLabel currentsystemtime = new JLabel(new java.util.Date(System.currentTimeMillis()).toString());
currentsystemtime.setBounds(new Rectangle(28, 78, 179, 16));
this.setSize(239, 120);
this.setLayout(null);
this.add(currentsystemtime, null);
}
}
I said use the code formatting codes.... reading unformatted code makes my brain ache
Main.java
public static void main(String[] args) {
// TODO Auto-generated method stub
new SimpleThread().start();
Delpan delp = new Delpan();
}
}
SimpleThread.java
class SimpleThread extends Thread {
Delpan del = new Delpan();
public SimpleThread() {
super();
}
public String cur_time;
Calendar cal = Calendar.getInstance(TimeZone.getDefault());
public void run() {
while(true)
{
Calendar cal = Calendar.getInstance(TimeZone.getDefault());
cur_time = String.valueOf(cal.getTime());
try {
sleep(1000);
} catch (InterruptedException ie) {System.out.println("Exception"+ie);}
System.out.println("Time Dispaly "+cur_time);
}
}
}
Delpan.java
public class Delpan extends JPanel {
private static final long serialVersionUID = 1;
public Delpan() {
super();
initialize();
}
private void initialize() {
JLabel currentsystemtime = new JLabel(new java.util.Date(System.currentTimeMillis()).toString());
currentsystemtime.setBounds(new Rectangle(28, 78, 179, 16));
this.setSize(239, 120);
this.setLayout(null);
this.add(currentsystemtime, null);
}
}
Your code example would never work as you don't have any references to you panel within the Thread class.
Try something more like this: -
import java.awt.BorderLayout;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Timer;
import java.util.TimerTask;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.SwingConstants;
import javax.swing.SwingUtilities;
public class ThreadTimerExample {
private Timer timer;
private JFrame jFrame = null;
private JPanel jContentPane = null;
private JLabel jLabel = null;
/**
* This method initializes jFrame
*
* @return javax.swing.JFrame
*/
private JFrame getJFrame() {
if (jFrame == null) {
jFrame = new JFrame();
jFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
jFrame.setSize(300, 200);
jFrame.setContentPane(getJContentPane());
jFrame.setTitle("Application");
}
return jFrame;
}
/**
* This method initializes jContentPane
*
* @return javax.swing.JPanel
*/
private JPanel getJContentPane() {
if (jContentPane == null) {
jLabel = new JLabel();
jLabel.setText(new SimpleDateFormat("dd MMM yyyy kk:mm:ss").format(Calendar.getInstance().getTime()));
jLabel.setHorizontalAlignment(SwingConstants.CENTER);
jContentPane = new JPanel();
jContentPane.setLayout(new BorderLayout());
jContentPane.add(jLabel, BorderLayout.CENTER);
}
return jContentPane;
}
private void startTimer() {
// Start the clock
timer = new Timer();
timer.schedule(new TimeTask(), 0, 1000);
}
/**
* Launches this application
*/
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
ThreadTimerExample application = new ThreadTimerExample();
application.getJFrame().setVisible(true);
application.startTimer();
}
});
}
class TimeTask extends TimerTask {
public void run() {
jLabel.setText(new SimpleDateFormat("dd MMM yyyy kk:mm:ss").format(Calendar.getInstance().getTime()));
}
}
}

I made something similiar a few days ago.
It displays the current system time in the JFrame in a Jlabel using a thread. Might not be the best code i created Java wise, but it works.
