Example

The following example shows the usage of java.util.GregorianCalendar.equals() method.

package com.tutorialspoint;

import java.util.*;

public class GregorianCalendarDemo {

   public static void main(String[] args) {

      // create a new calendar
      GregorianCalendar cal1 = 
              (GregorianCalendar) GregorianCalendar.getInstance();

      // print the current date and time
      System.out.println("" + cal1.getTime());

      // create a second calendar equal to first one
      GregorianCalendar cal2 = (GregorianCalendar) (Calendar) cal1.clone();

      // print cal2
      System.out.println("" + cal2.getTime());

      // compare the two calendars
      System.out.println("Cal1 and Cal2 are equal:" + cal1.equals(cal2));

      // change cal 2 a bit
      cal2.add(GregorianCalendar.YEAR, 5);

      // compare the two calendars
      System.out.println("Cal1 and Cal2 are equal:" + cal1.equals(cal2));

   }
}

Let us compile and run the above program, this will produce the following result:

Fri May 18 02:40:39 EEST 2012
Fri May 18 02:40:39 EEST 2012
Cal1 and Cal2 are equal:true
Cal1 and Cal2 are equal:false
