The date picker lets the user select the Date through an easy interface that 
pops up with a Calendar. The user can navigate through the Calendar and select 
a date. It contains an editable date picker, a date field, a multiple month 
calendar and a month component. You can select any date from the Date Picker.

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);;

    String day = "";
    JDialog d;
    JButton[] button = new JButton[49];
 
    public DatePicker(JFrame parent) {
        d = new JDialog();
