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 :)
