ChronoLocalDateTime isAfter() method in Java with Examples

Last Updated : 29 May, 2019
The isAfter() method of ChronoLocalDateTime interface in Java is used to check if the date, passed as the parameter, is after this ChronoLocalDateTime instance or not. It returns a boolean value showing the same. Syntax: 
default boolean isAfter(ChronoLocalDateTime otherDate)
Parameter: This method accepts a parameter otherDate which specifies the other date-time to be compared to this ChronoLocalDateTime. 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 ChronoLocalDateTime.isAfter() method: Program 1: Java 
// 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
        ChronoLocalDateTime dt1
            = LocalDateTime.parse("2018-11-03T12:45:30");

        // Prints the date
        System.out.println(dt1);

        // Parses the date
        ChronoLocalDateTime dt2
            = LocalDateTime.parse("2016-12-04T12:45:30");

        // Prints the date
        System.out.println(dt2);

        // Compares both dates
        System.out.println(dt1.isAfter(dt2));
    }
}
Output: 
2018-11-03T12:45:30
2016-12-04T12:45:30
true
Program 2: Java 
// 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
        ChronoLocalDateTime dt1
            = LocalDateTime.parse("2018-11-03T12:45:30");

        // Prints the date
        System.out.println(dt1);

        // Parses the date
        ChronoLocalDateTime dt2
            = LocalDateTime.parse("2019-12-04T12:45:30");

        // Prints the date
        System.out.println(dt2);

        // Compares both dates
        System.out.println(dt1.isAfter(dt2));
    }
}
Output: 
2018-11-03T12:45:30
2019-12-04T12:45:30
false
