Date to Calendar Java

Sometimes in Java, it is necessary to convert in between Date to Calendar and Calendar to Date classes.

Note: It is assumed that you know about the basic concepts of class Date and class GregorianCalendar.

It is done in the following code.

import java.util.*;
public class DateToCalendar
{
  public static void main(String args[])
  {
   Date d1 = new Date();                    // create java.util.Date object
   System.out.println(d1);
	
   Calendar cal1 = Calendar.getInstance();  // create Calendar object
   cal1.setTime(d1);                        // now Date comes into Calendar
   System.out.println(cal1);    
  }
}
