There's a getText method or something like that... and there are regex matchers.

I believe you would have kept a button for submitting..write ur code (in Action event of submit button) to check for the valid format in the text field.If it is not the valid one, give him a JOptionPane's Warning message to tell him the proper format.Pradhip

You might also want to try JFormattedTextField's features: http://www-128.ibm.com/developerworks/java/library/j-mer0625/Mike

A JFormattedTextField is a JTextField.

So where had written something like:private JTextField myTF;

You change it toprivate JFormattedTextField myTF;

Now you are free to use the "extra" methods of JFormattedTextField

like isEditValid()

The API also gives an example of this classes use to verify input.

Here: http://java.sun.com/j2se/1.5.0/docs/api/javax/swing/JFormattedTextField.html

> i'am using eclipse(plugin visual editor)Throw it away and learn how to create UIs manually. Because you'd already be done setting up the JFormattedTextField if you weren't using a GUI editor, and would know how to do what you want without one, too.

> it works goode but i dont know how to display a choisen time like 12:11:15My guess would be "by supplying the correct date object, maybe from a Calendar".

with new Date() as input it shows the current time

Having tough time, Rene?

Dear zmerlicni, please, do stop for a while, take a pencil, a sheet of paper, log off from the forum, put aside the keyboard and think a little. What are the tools you need? You have them all - JFormattedTextField, SimpleDateFormat, Date and Calendar. Now think what you have to accomplish and break it to sequence of actions done using these tools and in no time you will have the solution.

> with new Date() as input it shows the current timeWhat do you think it would display if you don't use the current time, but 12:00:13 or whatever it was?
