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));
}
} |
Output:
2018-12-06T19:21:12.123+05:30[Asia/Calcutta] 2018-10-06T19:21:12.123+05:30[Asia/Calcutta] true
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));
}

Output:
2018-10-06T19:21:12.123+05:30[Asia/Calcutta] 2018-12-06T19:21:12.123+05:30[Asia/Calcutta] false
