LocalDate ofInstant() method in Java with Examples

The ofInstant(Instant instant, ZoneId zone) method of LocalDate class in Java is used to create an instance of LocalDate from an Instant and zone ID. These two parameters are passed to the method and on the basis of those, an instance of LocalDate is created. The calculation of the LocalDate follows the following step.

1. The zone Id and instant are used to obtain the offset from UTC/Greenwich as there can be only one valid offset for each instance.
2. Finally, the local date is calculated using the instant and the obtained offset.

Syntax:

public static LocalDate 
       ofInstant(Instant instant,
                 ZoneId zone)

Parameters: This method accepts two parameters:

• instant: It is of Instant type and represents the instant passed to create the date.
• zone: It is of ZoneId type and represent the offset.

Return Value: This method returns the localdate.

Exceptions: This method throws DateTimeException if the result exceeds the supported range.

Note: This method is included in LocalDate class in the latest version of Java only, therefore it might not run in few of the online compilers.

Below programs illustrate the ofInstant(Instant instant, ZoneId zone) method in Java:
Program 1:

// Java program to demonstrate
// LocalDate.ofInstant(
// Instant instant, ZoneId zone) method

import java.time.*;
import java.time.temporal.*;

public class GFG {
    public static void main(String[] args)
    {
        // Create LocalDate object
        LocalDate localdate
            = LocalDate.ofInstant(
                Instant.now(),
                ZoneId.systemDefault());

        // Print full date
        System.out.println("Date: "
                           + localdate);
    }
}

Output:

Date: 2020-05-13

Program 2:

// Java program to demonstrate
// LocalDate ofInstant() method

import java.time.*;
import java.time.temporal.*;

public class GFG {
    public static void main(String[] args)
    {
        // Create LocalDate object
        LocalDate localdate
            = LocalDate.ofInstant(
                Instant.now(),
                ZoneId.systemDefault());

        // Print year only
        System.out.println(
            "Year: "
            + localdate.getYear());
    }
}

Output:

Year: 2020
