Convert String to java.util.Date in Java 8

Question

Currently I have a requirement to convert String to java.util.Date. Found many tutorials to convert string to Date by using java.text.SimpleDateFormatter. But my concern in this SimpleDateFormatter is not thread safe. Is there any possibility to convert string to java.util.Date by using java.time package in Java 8. Since java.time package classes are thread safe.

The fact that `SimpleDateFormat` is not thread safe is not a problem. Just create a new instance each time you need it. *Premature optimization is the root of all evil.* — Arnaud Denoyelle, Mar 18 '15 at 10:36
Are you definitely using it in a multi-threaded environment? If not, you don't need to worry about it being threadsafe — Trisha, Mar 18 '15 at 11:01

To answer the question about java.time from Java SE 8:

You could use:

LocalDateTime date = LocalDateTime.parse(someDateString);

and to convert it to date you could use:

Instant instant = date.atZone(ZoneId.systemDefault()).toInstant();
Date res = Date.from(instant);

Here `parse()` method return type is `LocaleDate`, but I need `java.util.Date` – Paramesh Korrakuti Mar 18 '15 at 10:45
