In this Java core tutorial we learn how to convert java.time.LocalDate object to java.util.Date object in Java programming language.

How to convert LocalDate to Date in Java

In Java to convert a LocalDate object to Date object we can follow these step

  • Firstly convert LocalDate to a ZonedDateTime
  • Secondly convert ZonedDateTime to Instant object
  • And then create a new Date object from the Instant.

In the following Java program we show how to convert LocalDate to Date as the step by step above.

ConvertLocalDateToDateExample1.java 

import java.time.Instant;
import java.time.LocalDate;
import java.time.ZoneId;
import java.time.ZonedDateTime;
import java.util.Date;

public class ConvertLocalDateToDateExample1 {
    public static void main(String... args) {
        LocalDate localDate = LocalDate.of(2022, 7, 11);

        ZonedDateTime zonedDateTime = localDate.atStartOfDay(ZoneId.systemDefault());
        Instant instant = zonedDateTime.toInstant();
        Date date = Date.from(instant);

        System.out.println("LocalDate: " + localDate);
        System.out.println("Date: " + date);
    }
}
The output as below. 
LocalDate: 2022-07-11
Date: Mon Jul 11 00:00:00 ICT 2022

Or we can write the Java code in one line as below. 

Date date = Date.from(localDate.atStartOfDay(ZoneId.systemDefault()).toInstant());

The following Java program to show how to LocalDate to Date with one line of code above.

ConvertLocalDateToDateExample2.java 

import java.time.LocalDate;
import java.time.ZoneId;
import java.util.Date;

public class ConvertLocalDateToDateExample2 {
    public static void main(String... args) {
        LocalDate localDate = LocalDate.of(2022, 7, 11);

        Date date = Date.from(localDate.atStartOfDay(ZoneId.systemDefault()).toInstant());

        System.out.println("LocalDate: " + localDate);
        System.out.println("Date: " + date);
    }
}
The output as below. 
LocalDate: 2022-07-11
Date: Mon Jul 11 00:00:00 ICT 2022

Happy Coding 😊
