import javax.swing.*;
import javax.swing.text.MaskFormatter;
import javax.swing.text.DateFormatter;
import java.awt.*;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.text.ParseException;
import java.util.Date;

public class FormattedTextFieldExample extends JFrame {
public FormattedTextFieldExample() {
initComponents();
}

private void initComponents() {
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(new Dimension(200, 200));
getContentPane().setLayout(new FlowLayout(FlowLayout.LEFT));

MaskFormatter mask = null;
try {
//
// Create a MaskFormatter for accepting phone number, the # symbol accept
// only a number. We can also set the empty value with a place holder
// character.

mask = new MaskFormatter("(###) ###-####");
mask.setPlaceholderCharacter('_');
} catch (ParseException e) {
e.printStackTrace();
}

//
// Create a formatted text field that accept a valid phone number.
//
JFormattedTextField phoneField = new JFormattedTextField(mask);
phoneField.setPreferredSize(new Dimension(100, 20));

//
// Here we create a formatted text field that accept a date value. We
// create an instance of SimpleDateFormat and use it to create a
// DateFormatter instance which will be passed to the JFormattedTextField.
//
DateFormat format = new SimpleDateFormat("dd-MMMM-yyyy");
DateFormatter df = new DateFormatter(format);
JFormattedTextField dateField = new JFormattedTextField(df);
dateField.setPreferredSize(new Dimension(100, 20));
dateField.setValue(new Date());

getContentPane().add(phoneField);
getContentPane().add(dateField);
}

public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
new FormattedTextFieldExample().setVisible(true);
}
});
}
}
