The isAfter() method of ChronoZonedDateTime interface in Java is used to check if the date, passed as the parameter, is after this ChronoZonedDateTime instance or not. It returns a boolean value showing the same.
Syntax:
public boolean isAfter(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 after the specified date-time.
Below programs illustrate the ChronoZonedDateTime.isAfter() method:
Program 1:
// Program to illustrate the isAfter() 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( "2018-10-06T19:21:12.123+05:30[Asia/Calcutta]" ); // Prints the date System.out.println(dt2); // Compares both dates System.out.println(dt1.isAfter(dt2)); } } |

Program 2:
// Program to illustrate the isAfter() 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.isAfter(dt2)); } } |
