You don't need to do anything with that format until you decide to display it to the user. In that moment need to format that date to the way you would like to display it, and you do it with the SimpleDateFormat, that returns a String in the format you specified, in your case " " using the posted pattern.

Timestamp Online also supports countdown, so you can see, how much time remains to particular timestamp. These examples are showing how to get current unix timestamp in seconds. These examples are returning timestamp in seconds, although some of the languages are returning timestamp in milliseconds.
These examples are showing how to get current date and time that could be presented to the end-user. These examples are showing how to convert timestamp - either in milliseconds or seconds to human readable form. These examples are showing how to parse date in human readable form to unix timestamp in either milliseconds or seconds. Unix time also known as POSIX time or Epoch time is a system for describing instants in time, defined as the number of seconds that have elapsed since Coordinated Universal Time UTC , Thursday, 1 January , not counting leap seconds.

The canonical reference for building a production grade API with Spring. In this tutorial, we'll explore several ways to convert String objects into Date objects. We'll start with the new Date Time API, java.
time , that was introduced in Java 8 before looking at the old java. Date data type also used for representing dates. To conclude, we'll look at some external libraries for conversion using Joda-Time and the Apache Commons Lang DateUtils class.
LocalDate and LocalDateTime are immutable date-time objects that represent a date, and a date and time, respectively. By default, Java dates are in the ISO format, so if we have any string which represents a date and time in this format, then we can use the parse API of these classes directly.
Interested in working as a Java developer intern? Check out Jooble! T he Date-Time API provides parse methods for parsing a String that contains date and time information.
In our first example, let's convert a String to a java. LocalDate :. A similar approach to the above can be used to convert a String to a java. LocalDateTime :. It is important to note that both the LocalDate and LocalDateTime objects are timezone agnostic. However, when we need to deal with time zone specific dates and times, we can use the ZonedDateTime parse method directly to get a time zone specific date time:.
Converting a String with a custom date format into a Date object is a widespread operation in Java. For this purpose we'll use the DateTimeFormatter class, which provides numerous predefined formatters, and allows us to define a formatter. Let's start with an example of using one of the predefined formatters of DateTimeFormatter :.
For a full list of symbols that we can use to specify a pattern for parsing click here. If we need to convert java. time dates into the older java. Date object, read this article for more details. Before Java 8, the Java date and time mechanism was provided by the old APIs of java. Date , java. Calendar , and java. TimeZone classes, which we sometimes still need to work with.
In the above example, we first need to construct a SimpleDateFormat object by passing the pattern describing the date and time format. Next we need to invoke the parse method passing the date String. If the String argument passed is not in the same format as the pattern, then a ParseException will be thrown.
It's important to note that the java. Date has no concept of time zone , and only represents the number of seconds passed since the Unix epoch time — TZ.
However, when we print the Date object directly, it will always be printed with the Java default system time zone. In this final example, we'll look at how to format a date while adding the time zone information:. Now that we have a good understanding of how to convert String objects to Date objects using the new and old APIs offered by core Java, let's take a look at some external libraries.
An alternative to the core Java Date and Time library is Joda-Time. Although the authors now recommend that users migrate to java. time JSR , if this isn't possible then the Joda-Time library provides an excellent alternative for working with Date and Time.
This library provides pretty much all the capabilities supported in the Java 8 Date Time project. The artifact can be found on Maven Central :.
The DateUtils class provides many useful utilities, making it easier to work with the legacy Calendar and Date objects. The commons-lang3 artifact is available from Maven Central :. Let's convert a date String into a java. Date using an Array of date patterns:. In this article, we illustrated several ways of converting Strings to different types of Date objects with and without time , both in plain Java as well as using external libraries.
