Using JFormattedTextField with strict SimpleDateFormat

Hello, here I'm going to show you how to use JFormattedTextField with a strict SimpleDateFormat in a tiny program.

import javax.swing.*;

import java.awt.*;

import java.text.*;

class JFormattedFieldExample extends JFrame


{

JFormattedTextField t;




 public JFormattedFieldExample()

 {

  createAndShowGUI();

 }

 

 private void createAndShowGUI()

 {

  setTitle("JFormattedField Example");

  setDefaultCloseOperation(EXIT_ON_CLOSE);

  setLayout(new FlowLayout());

  

  SimpleDateFormat s=new SimpleDateFormat("dd/MM/yyyy");

  

  // Make it strict, so that it doesn't allow

  // some conditions like, if month > 12

  // day > 31 etc.

  s.setLenient(false);

  

  t=new JFormattedTextField(s);

  t.setColumns(20);

  

  try

  {

  t.setValue(s.parse("01/01/1996"));

  }catch(Exception e){}

  

  add(t);

  

  pack();

  setLocationRelativeTo(null);

  setVisible(true); 

 }

 

 public static void main(String args[])

 {

  new JFormattedFieldExample();

 }

}

The greatest compliment you can give me is when you share this with others. I sincerely appreciate it :)
