ChronoLocalDateTime isEqual() method in Java with Examples

Last Updated : 29 May, 2019

The isEqual() method of ChronoLocalDateTime interface in Java is used to check if the date, passed as the parameter, is equal to this ChronoLocalDateTime instance or not. It returns a boolean value showing the same. Syntax:

public boolean isEqual(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 equal to the specified date-time. Below programs illustrate the ChronoLocalDateTime.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
        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.isEqual(dt2));
    }
}

Output:

2018-11-03T12:45:30
2016-12-04T12:45:30
false

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
        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.isEqual(dt2));
    }
}

Output:

2018-11-03T12:45:30
2019-12-04T12:45:30
false
