    Where is the main() method so the code can be executed for testing?

    I actually created a actionlistener for a button to display the datePicker class.[[code]]

    private class DateListener implements ActionListener{
    public void actionPerformed(ActionEvent e){
    returndatetext.setText(new DatePicker().setPickedDate());

    }
    }
    [[code]]
    thanks

    Do you have code with a main() method for testing the class?

    What is the [[code]] for?


    Please edit your post and wrap your code with
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.
