ChronoZonedDateTime isEqual() method in Java with Examples Last Updated : 30 May, 2019 Comments Improve Suggest changes Like Article Like Report The isEqual() method of ChronoZonedDateTime interface in Java is used to check if the date, passed as the parameter, is equal to this ChronoZonedDateTime instance or not. It returns a boolean value showing the same. Syntax: default boolean isEqual(ChronoZonedDateTime otherDate) Parameter: This method accepts a parameter otherDate which specifies the other date-time to be compared to this ChronoZonedDateTime. It should not be null. Returns: The function returns boolean value showing if this date-time is equal to the specified date-time. Below programs illustrate the ChronoZonedDateTime.isEqual() method: Program 1: Java // Program to illustrate the isEqual() method import java.util.*; import java.time.*; import java.time.chrono.*; public class GfG { public static void main(String[] args) { // Parses the date ChronoZonedDateTime dt1 = ZonedDateTime.parse( "2018-12-06T19:21:12.123+05:30[Asia/Calcutta]"); // Prints the date System.out.println(dt1); // Parses the date ChronoZonedDateTime dt2 = ZonedDateTime.parse( "2018-12-06T19:21:12.123+05:30[Asia/Calcutta]"); // Prints the date System.out.println(dt2); // Compares both dates System.out.println(dt1.isEqual(dt2)); } } Output: 2018-12-06T19:21:12.123+05:30[Asia/Calcutta] 2018-12-06T19:21:12.123+05:30[Asia/Calcutta] true Program 2: Java // Program to illustrate the isEqual() method import java.util.*; import java.time.*; import java.time.chrono.*; public class GfG { public static void main(String[] args) { // Parses the date ChronoZonedDateTime dt1 = ZonedDateTime.parse( "2018-10-06T19:21:12.123+05:30[Asia/Calcutta]"); // Prints the date System.out.println(dt1); // Parses the date ChronoZonedDateTime dt2 = ZonedDateTime.parse( "2018-12-06T19:21:12.123+05:30[Asia/Calcutta]"); // Prints the date System.out.println(dt2); // Compares both dates System.out.println(dt1.isEqual(dt2)); } } Output: 2018-10-06T19:21:12.123+05:30[Asia/Calcutta] 2018-12-06T19:21:12.123+05:30[Asia/Calcutta] false Reference: https://docs.oracle.com/javase/9/docs/api/java/time/chrono/ChronoZonedDateTime.html#isEqual-java.time.chrono.ChronoZonedDateTime- Comment More infoAdvertise with us Next Article Introduction to Java S ShubhamMaurya3 Follow Improve Article Tags : Misc Java Java-Functions Java-ChronoZonedDateTime Java-Time-Chrono package +1 More Practice Tags : JavaMisc Similar Reads Java Tutorial Java is a high-level, object-oriented programming language used to build web apps, mobile applications, and enterprise software systems.
