How to convert ZonedDateTime to Date in Java?



Problem Description :


Write a program in Java that converts ZonedDateTime to Date.

Concept :


Date class is present in java.util.* package and ZonedDateTime class is present in java.time.* package that is part of Java 8 API.  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 ZonedDateTime 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.time.ZonedDateTime;
import java.util.Date;

public class ConvertZonedDateTimeToDate {

 public static void main(String[] args) {

  //Get default time zone
  ZoneId defaultTimeZone = ZoneId.systemDefault();
  // Get current date and time.
  LocalDateTime localDateTime = LocalDateTime.now();
  ZonedDateTime zonedDateTime = localDateTime.atZone(defaultTimeZone);
  System.out.println("ZonedDateTime : " + zonedDateTime);
  // ZonedDateTime to Instant
  Instant instant = zonedDateTime.toInstant();
  // Convert Instant to Date.
  Date date = Date.from(instant);
  System.out.println("Date : " + date);

 }

}
