Comparing Different Dated GregorianCalendar instances for Equality Example

The following example shows the usage of Java Calendar equals() method. We're creating two GregorianCalendar instance of different dates. We're comparing them using equals() method and then printing the result.

package com.tutorialspoint;

import java.util.Calendar;
import java.util.GregorianCalendar;

public class CalendarDemo {
   public static void main(String[] args) {

      // create two calendar at the different dates
      Calendar cal1 = new GregorianCalendar(2015, 8, 15);
      Calendar cal2 = new GregorianCalendar(2008, 1, 02);

      // compare the two calendar objects for equality.
      System.out.println("The result is : " + cal1.equals(cal2));
   }
}

Output

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

The result is : false

Comparing Same Dated GregorianCalendar instances for Equality Example

The following example shows the usage of Java Calendar equals() method. We're creating two GregorianCalendar instance of same date. We're comparing them using equals() method and then printing the result.

package com.tutorialspoint;

import java.util.Calendar;
import java.util.GregorianCalendar;

public class CalendarDemo {
   public static void main(String[] args) {

      // create two calendar at the different dates
      Calendar cal1 = new GregorianCalendar(2015, 8, 15);
      Calendar cal2 = new GregorianCalendar(2015, 8, 15);

      // compare the two calendar objects for equality.
      System.out.println("The result is : " + cal1.equals(cal2));
   }
}

Output

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

The result is : true

Comparing Current Dated GregorianCalendar instances for Equality Example

The following example shows the usage of Java Calendar compareTo() method. We're creating two Calendar instance of current date and then we're comparing them using compareTo() method and then printing the result. As there is a very small difference of milliseconds, the result will come as false.

package com.tutorialspoint;

import java.util.Calendar;

public class CalendarDemo {
   public static void main(String[] args) {

      // create two calendar at the different dates
      Calendar cal1 = Calendar.getInstance();
      Calendar cal2 = Calendar.getInstance();
	  
      // compare the two calendar objects for equality.
      System.out.println("The result is : " + cal1.equals(cal2));
   }
}

Output

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

The result is : false
