How To Convert Java.Util.Date To Java.Time.Localdate Inwards Coffee Eight - Example

The easiest agency to convert a java.util.Date to java.time.LocalDate is via Instant, which is the equivalent degree of java.util.Date inwards JDK 8. You tin post away commencement convert util Date to Instant as well as and so practise a LocalDateTime object from that instant at your default timezone. Once y'all cause got an instant of LocalDateTime, y'all tin post away easily convert that to LocalDate or LocalTime inwards Java. If y'all are non living nether the stone inwards final 2 years that its 2016 as well as Java 8 has been around for to a greater extent than than 2 years, 18th March 2014 Java SE 8 GA happened. In the 3rd endeavor of designing a robust appointment as well as fourth dimension API, JDK 8 has come upwardly up alongside JSR 318 novel Date as well as Time API as well as many programmers cause got already started using it.


The novel API is meant to supervene upon our onetime but non so gold, but withal ubiquitous java.util.Date as well as Calendar API, but unfortunately conversion betwixt java.util.Date to java.time.LocalDate, java.time.LocalTime is non that straightforward.

You necessitate to cross a twain of bridges to achieve there. This is the start of Java 8 conversion tutorial serial where I'll portion lots of tutorial most converting onetime appointment classes to novel appointment as well as fourth dimension classes inwards Java 8.

Steps to convert java.util.Date to java.time.LocalDate

Here are the steps y'all necessitate to follow to perform this conversion:

1. Convert java.util.Date to java.time.Instant class
2. Convert java.time.Instant to java.time.LocalDateTime using System's default timezone.
3. Convert java.time.LocalDateTime to java.time.LocalDate inwards Java

It's slow to shout out back these steps i time y'all are familiar alongside novel Date as well as Time API as well as how it is related to onetime appointment API. For example, the equivalent degree of java.util.Date inwards novel API is Instant, thus y'all volition detect the toInstant() method inwards java.util.Date class. Just similar onetime classes was a millisecond value from Epoch, Instant is equally good an instant inwards fourth dimension scale but it doesn't attention most fourth dimension zone but LocalDatetime degree uses local Timezone.

That's why when y'all convert an Instant to LocalDateTime, it needed a timezone. The LocalDateTime degree has both appointment as well as fourth dimension component, so if y'all only necessitate appointment part, y'all tin post away purpose the toLocalDate() method to convert LocalDatetTime to LocalDate equally shown inwards the next the example.

Java Program to convert java.util.Date to java.time.LocalDate

Here is our Java programme to convert the java.util.Date to novel java.time.LocalDate inwards Java 8.

package test;  import java.time.Instant; import java.time.LocalDate; import java.time.LocalDateTime; import java.time.ZoneId; import java.util.Date;  /** * Java Program to convert java.util.Date to java.time.LocalDate inwards JDK8 */ public class Test {  public static void main(String[] args) {  // converting java.util.Date to java.time.LocalDate Date today = new Date(); Instant instant = Instant.ofEpochMilli(today.getTime()); LocalDateTime localDateTime = LocalDateTime.ofInstant(instant, ZoneId.systemDefault()); LocalDate localDate = localDateTime.toLocalDate();  System.out.println("java.util.Date: " + today); System.out.println("java.time.LocalDate: " + localDate);  }  }  Output java.util.Date: Thu Jun 09 15:02:16 PDT 2016 java.time.LocalDate: 2016-06-09

You tin post away encounter that both java.util.Date as well as java.time.LocalDate has the same value. In side past times side article, we'll cause got a await at the reverse of this i.e. volition convert novel appointment degree to onetime appointment degree inwards Java 8. Please see Java SE 8 for Really Impatient past times Cay S. Horstmann to larn to a greater extent than novel Date as well as Time API of Java 8 inwards quick time.
