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 :)
