LocalDateTime isEqual() method in Java with Examples

The isEqual() method of LocalDateTime class in Java is used to check if this date is equal to the specified date-time.

Syntax:

public boolean isEqual(ChronoLocalDateTime other)

Parameter: This method accepts a parameter other which specifies the other date-time to be compare to. It should not be null.

Returns: The function returns boolean value if this date-time is equal to the specified date-time.

Below programs illustrate the LocalDateTime.isEqual() method:

Program 1:

// Program to illustrate the isEqual() method

import java.util.*;
import java.time.*;

public class GfG {
    public static void main(String[] args)
    {
        // Parses the date
        LocalDateTime dt1
            = LocalDateTime
                  .parse("2018-11-03T12:45:30");

        // Prints the date
        System.out.println("Date 1: " + dt1);

        // Parses the date
        LocalDateTime dt2
            = LocalDateTime
                  .parse("2018-11-03T12:45:30");

        // Prints the date
        System.out.println("Date 2: " + dt2);

        // Compares the date
        System.out.println("After comparison: "
                           + dt2.isEqual(dt1));
    }
}

Output:

Date 1: 2018-11-03T12:45:30
Date 2: 2018-11-03T12:45:30
After comparison: true

Program 2:

// Program to illustrate the isEqual() method

import java.util.*;
import java.time.*;

public class GfG {
    public static void main(String[] args)
    {
        // Parses the date
        LocalDateTime dt1
            = LocalDateTime
                  .parse("2010-12-05T12:50:30");

        // Prints the date
        System.out.println("Date 1: " + dt1);

        // Parses the date
        LocalDateTime dt2
            = LocalDateTime
                  .parse("2012-05-10T12:50:30");

        // Prints the date
        System.out.println("Date 2: " + dt2);

        // Compares the date
        System.out.println("After comparison: "
                           + dt2.isEqual(dt1));
    }
}

Output:

Date 1: 2010-12-05T12:50:30
Date 2: 2012-05-10T12:50:30
After comparison: false
