The equals() method of ChronoZonedDateTime interface in Java is used to compare this ChronoZonedDateTime to the another date-time object passed as parameter. The comparison is based on the offset date-time and the zone. Only objects of type ChronoZonedDateTime are compared with each other and other types return false. The value to be returned by this method is determined as follows:
- if both ChronoZonedDateTime are equal, then true is returned.
- if both ChronoZonedDateTime are not equal, then false is returned.
Syntax:
boolean equals(Object obj)
Parameters: This method accepts a single parameter obj which represents the object to compare with this ChronoZonedDateTime. This is a mandatory parameter and it should not be null.
Return value: This method returns true if both ChronoZonedDateTime are equal else false.
Below programs illustrate the equals() method of ChronoZonedDateTime in Java:
Program 1:
// Program to illustrate the equals() method import java.util.*;import java.time.*;import java.time.chrono.*; public class GfG { public static void main(String[] args) { // First date ChronoZonedDateTime dt = ZonedDateTime.parse( "2018-12-06T19:21:12.123+05:30[Asia/Calcutta]"); System.out.println(dt); // Second date ChronoZonedDateTime dt1 = ZonedDateTime.parse( "2018-12-06T19:21:12.123+05:30[Asia/Calcutta]"); System.out.println(dt1); try { // Compare both dates System.out.println(dt1.equals(dt)); } catch (Exception e) { System.out.println(e); } }} |

Program 2:
// Program to illustrate the equals() method import java.util.*;import java.time.*;import java.time.chrono.*; public class GfG { public static void main(String[] args) { // First date ChronoZonedDateTime dt = ZonedDateTime.parse( "2018-10-25T23:12:31.123+02:00[Europe/Paris]"); System.out.println(dt); // Second date ChronoZonedDateTime dt1 = ZonedDateTime.parse( "2018-12-06T19:21:12.123+05:30[Asia/Calcutta]"); System.out.println(dt1); try { // Compare both dates System.out.println(dt1.equals(dt)); } catch (Exception e) { System.out.println(e); } }} |
