You can do this easily with a Timer.

Actually I have already implemented a code to retrieve the values that are to be shown on the UI but I am facing difficulty in showing them on the JFrame i.e in the JTextFields..

The textfields show no content...

What do you think can my mistake be possibly??

I have no idea, since you didn't post any of that code here, and that has nothing to do with the question that you did ask.

public static void tri() {
       
        
        ClassLoadingMXBean classmxbean = ManagementFactory.getClassLoadingMXBean();
        ThreadMXBean threadmxbean = ManagementFactory.getThreadMXBean();

int thread_count = threadmxbean.getThreadCount();
        int peak_thread_count = threadmxbean.getPeakThreadCount();
        int daemon_thread_count = threadmxbean.getDaemonThreadCount();

Trail1 tt = new Trail1();
       
        try {

tt.thrd_ct.setText(Integer.toString(thread_count));
              tt.pk_thrd_ct.setText(Integer.toString(peak_thread_count));
              tt.demon_thrd_ct.setText(Integer.toString(daemon_thread_count));

tt.thrd_ct.repaint();
              tt.pk_thrd_ct.repaint();
              tt.demon_thrd_ct.repaint();

} catch (NullPointerException e) {
        
         
         }
    }  
 }


public class Trail1 {

public static JTextField thrd_ct;
    public static JTextField pk_thrd_ct;
    public static JTextField demon_thrd_ct;

 public void tri1() {
     
       JFrame frme = new JFrame();

       JLabel peak_thrd_cnt = new JLabel();
       JLabel demon_thrd_cnt = new JLabel();

       thrd_cnt.setBounds(100,180,200,50);

frme.getContentPane().add(thrd_cnt);
       frme.getContentPane().add(peak_thrd_cnt);
       frme.getContentPane().add(demon_thrd_cnt);

 frme.getContentPane().add(thrd_ct);
       frme.getContentPane().add(pk_thrd_ct);
       frme.getContentPane().add(demon_thrd_ct);

frme.setTitle("JVM Monitoring");
  	frme.setLocation(new Point(0, 0));
  	frme.setSize(new Dimension(1100, 800));
  	frme.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
  	frme.setResizable(false); 
        frme.setLayout(null);
       
         frme.setVisible(true);      
         frme.getContentPane().setVisible(true);
         frme.validate();
         frme.getContentPane().validate();        
 }   
}

I am creating the JFrame in Trail1 class..
Creating an instance of it in the Trial() class..
The tri() function is in a loop that executes to bring the values every 1000 secs...

Hope the idea is clear...

Please try and help..its really important..
I am trying this since long...
