How to convert Date to LocalDateTime in Java?



Problem Description :


Write a program in Java that converts current Date to LocalDateTime.

Concept :


Date class is present in java.util.* package and LocalDateTime class is present in java.time.* package that is part of Java 8 API. Date class returns current time and time zone along with current date but LocalDateTime class returns current date and time. This conversion is very useful for large projects because it is a very basic problem that you should be aware.

Note : Java 8 is required to run below code because LocalDateTime class is in Java 8 API.


Java Program :


package com.javamultiplex.datetime;

import java.time.Instant;
import java.time.LocalDateTime;
import java.time.ZoneId;
import java.util.Date;

/**

public class ConvertDateToLocaleDateTime {

 public static void main(String[] args) {

  Date date = new Date();
  System.out.println("Date : " + date);
  // Get system default time zone id.
  ZoneId defaultZoneId = ZoneId.systemDefault();
  // Convert Date to Instant.
  Instant instant = date.toInstant();
  // Instant + default time zone + LocalDateTime
  LocalDateTime localDateTime = instant.atZone(defaultZoneId).toLocalDateTime();
  System.out.println("LocalDateTime : " + localDateTime);
 }
