Importance of ofInstant() method in Java 9?

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.


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


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);


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