attach a calendar in java

Hello Friend,

Try the following code:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
class DatePicker{
  int month = java.util.Calendar.getInstance().get(java.util.Calendar.MONTH);
  int year = java.util.Calendar.getInstance().get(java.util.Calendar.YEAR);;
  JLabel l = new JLabel("",JLabel.CENTER);
  String day = "";
  JDialog d;
  JButton[] button = new JButton[49];
  public DatePicker(JFrame parent){
   d = new JDialog();
   d.setModal(true);
   String[] header = {"Sun","Mon","Tue","Wed","Thur","Fri","Sat"};
   JPanel p1 = new JPanel(new GridLayout(7,7));
  p1.setPreferredSize(new Dimension(430,120));

   for(int x = 0; x < button.length; x++){
      final int selection = x;
      button[x] = new JButton();
      button[x].setFocusPainted(false);
      button[x].setBackground(Color.white);
      if(x>6)button[x].addActionListener(new ActionListener(){
        public void actionPerformed(ActionEvent ae){
        day = button[selection].getActionCommand();
        d.dispose();
        }});
      if(x < 7){
      button[x].setText(header[x]);
      button[x].setForeground(Color.red);
      }
       p1.add(button[x]);
    }
    JPanel p2 = new JPanel(new GridLayout(1,3));
    JButton previous = new JButton("<< Previous");
    previous.addActionListener(new ActionListener(){
      public void actionPerformed(ActionEvent ae){
      month--;
      displayDate();}});
    p2.add(previous);
    p2.add(l);
    JButton next = new JButton("Next >>");
    next.addActionListener(new ActionListener(){
    public void actionPerformed(ActionEvent ae){
    month++;
    displayDate();
    }
    });
    p2.add(next);
    d.add(p1,BorderLayout.CENTER);
    d.add(p2,BorderLayout.SOUTH);
    d.pack();
    d.setLocationRelativeTo(parent);
    displayDate();
    d.setVisible(true);
   }
  public void displayDate(){
    for(int x = 7; x < button.length; x++) button[x].setText("");
    java.text.SimpleDateFormat sdf = new java.text.SimpleDateFormat("MMMM yyyy");
    java.util.Calendar cal = java.util.Calendar.getInstance();
    cal.set(year,month,1);
    int dayOfWeek = cal.get(java.util.Calendar.DAY_OF_WEEK);
    int daysInMonth = cal.getActualMaximum(java.util.Calendar.DAY_OF_MONTH);
    for(int x = 6+dayOfWeek,day = 1; day <= daysInMonth; x++,day++) button[x].setText(""+day);
    l.setText(sdf.format(cal.getTime()));
   d.setTitle("Date Picker");
  }
  public String setPickedDate() {
   if(day.equals("")) return day;
      java.text.SimpleDateFormat sdf = new java.text.SimpleDateFormat("dd-MM-yyyy");
      java.util.Calendar cal = java.util.Calendar.getInstance();
      cal.set(year,month,Integer.parseInt(day));
      return sdf.format(cal.getTime());
   }
  }
class Picker{
    public static void main(String[] args){
    JLabel label = new JLabel("Selected Date:");
    final JTextField text = new JTextField(20);
    JButton b = new JButton("popup");
    JPanel p = new JPanel();
    p.add(label);
    p.add(text);
    p.add(b);
    final JFrame f = new JFrame();
    f.getContentPane().add(p);
    f.pack();
    f.setVisible(true);
    b.addActionListener(new ActionListener(){
      public void actionPerformed(ActionEvent ae){
        text.setText(new DatePicker(f).setPickedDate());
      }
    });
   }
}

Thanks

you can even try this .......But you need to have a jar file to execute this...if you need them i will forward it to your mail
