How to convert LocalDateTime to Date in Java?

Problem Description :

Write a program in Java that converts LocalDateTime to Date.

LocalDateTime to Date conversion

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 ConvertLocalDateTmeToDate {
	public static void main(String[] args) {
	// Get default time zone.
	ZoneId defaultTimeZone = ZoneId.systemDefault();
	// Get current date and time.
	LocalDateTime localDateTime = LocalDateTime.now();
	System.out.println("LocalDateTime : " + localDateTime);
	// Convert LocaleDateTime to Instant.
	Instant instant = localDateTime.atZone(defaultTimeZone).toInstant();
	// Convert Instant to Date.
	Date date = Date.from(instant);
	System.out.println("Date : " + date);
	}
	}
