Importance of ofInstant() method in Java 9?

JavaObject Oriented ProgrammingProgramming

In Java 9, the ofInstant() method has introduced for conversion. It is a static method of LocalDate, LocalTime, and LocalDateTime classes. This method converts java.time.Instant object to LocalDate that requires a time zone in the form of java.time.ZoneId.

Syntax

public static LocalTime ofInstant(Instant instant, ZoneId zone)
public static LocalDate ofInstant(Instant instant, ZoneId zone)
public static LocalDateTime ofInstant(Instant instant, ZoneId zone)

Example

import java.time.LocalDate;
import java.time.LocalTime;
import java.time.LocalDateTime;
import java.time.Instant;
import java.time.ZoneId;

public class OfInstantMethodTest {
   public static void main(String args[]) {
      Instant instant = Instant.parse("2020-02-05T02:35:15.245Z");
      System.out.println("Instant: " + instant);

      LocalDate ld = LocalDate.ofInstant(instant, ZoneId.of("Asia/Kolkata"));
      System.out.println("LocalDate: " + ld);

      LocalTime lt = LocalTime.ofInstant(instant, ZoneId.of("Asia/Kolkata"));
      System.out.println("LocalTime: " + lt);

      LocalDateTime ldt = LocalDateTime.ofInstant(instant, ZoneId.of("Asia/Kolkata"));
      System.out.println("LocalDateTime: " + ldt);
   }
}

Output

Instant: 2020-02-05T02:35:15.245Z
LocalDate: 2020-02-05
LocalTime: 08:05:15.245
LocalDateTime: 2020-02-05T08:05:15.245
