Dear Experts,
I am designing a JDialog which contains few jTextFields. One of that belongs to time. I am unable to set timer against that so as to get system time on the JDialog.
 I have tried but getting some error in timer = new Timer(500,this); Compilation showing error agains the word "this" and the error is " cannot be converted to java.awt.event.ActionListener by method invocation conversion". Please find the code for reference. If I remove the word "this" by "null" the error doesn't appair but required result not getting. onlt first time I am able to see the time on jTableField but not able to get real time after words.

Please help
Regards

try OuterClassName.this

where OuterClassName is the name of the class which holds the class implementation of ActionListener

Your class should really be extending JFrame not JDialog, and using JPanels with LayoutManagers to display your text fields etc.

@Override
                public void actionPerformed(ActionEvent evt) {
                actionPerformed(evt);//<< NO!
                };
        });

The above line in actionPerformed will do nothing other than cause problems by attempting to make a recursive call. Do something sensible in there instead - there's nothing otherwise wrong with the Timer
