Here is a complete example, that converts an UTC formatted date into MM/dd/yyyy and yyyy-MM-dd formats. New SimpleDateFormat("MM-dd-yyyy").format(myDate) Before Java 8, the Java date and time mechanism was provided by the old APIs of, , and classes which until this article is out. We can convert a from one format to another using SimpleDateFormat.įor example, if we want to convert a Date to MM/dd/yyyy, we can do the same using : Its becomes fundamental skill in Java (or other programming language you work with) to work with a string to represent a date, and then convert it into a Date object. DateTimeFormatter f DateTimeFormatter.ofPattern ( 'dd/MM/uuuu' ) LocalDate ld LocalDate.parse ( '', f ) Do not conflate a date-time object with a String representing its value. String output = outputFormat.format(date) Complete Example : Convert Date from one format to another using SimpleDateFormat To parse, or generate, a String representing a date-time value, use the DateTimeFormatter class. Here’s an example of how to format a date: This is done using the format() method of the SimpleDateFormat class. Step 3 : Formatting a Dateįinally, you can format the date and convert it to the desired output format. In this example, the date “12-06-2018” is parsed using the inputFormat object and stored in the “date” variable. Here’s an example of how to parse a date:ĭate date = inputFormat.parse("12-06-2018") This is done using the parse() method of the SimpleDateFormat class. The next step is to parse the input date and convert it to a Date object. In this example, the “inputFormat” object is set to the input format of “dd-MM-yyyy”, and the “outputFormat” object is set to the output format of “yyyy-MM-dd”. SimpleDateFormat outputFormat = new SimpleDateFormat("yyyy-MM-dd") SimpleDateFormat inputFormat = new SimpleDateFormat("dd-MM-yyyy") Here’s an example of how to create a SimpleDateFormat object: ![]() You’ll use this object to specify the input format and the output format. The first step in converting dates is to create a “SimpleDateFormat” object. Converting Dates from one Format to Another in Java Step 1 : Creating a SimpleDateFormat Object In this post, we’ll look at how to use the “SimpleDateFormat” class to convert dates from one format to another. Question: How to use ThreeTenABP in Android Project, with a very thorough explanation.In Java, you may need to convert dates from one format to another, whether it be for display purposes or to store the dates in a database.ThreeTenABP, Android edition of ThreeTen Backport.Java 8+ APIs available through desugaring.ThreeTen Backport project, the backport of java.time to Java 6 and 7 (ThreeTen for JSR-310).Java Specification Request (JSR) 310, where java.time was first described.Oracle tutorial: Date Time explaining how to use java.time.In the latter case make sure you import the date and time classes from with subpackages. On older Android either use desugaring or the Android edition of ThreeTen Backport. ![]() If using Java SE 8, please migrate to java. Date afterAddingTenMins new Date (t + (Integer. I would like to convert this string to Date object. Even in jodas website it says: 'Note that Joda-Time is considered to be a largely finished project. My application gives me a string like 1 day 15 min or 15 hours 10 min etc. In non-Android Java 6 and 7 get the ThreeTen Backport, the backport of the modern classes (ThreeTen for JSR 310 see the links at the bottom). Joda-Time is in maintainance mode and is being replaced by the new APIs, so I dont recommend start a new project with it.In Java 8 and later and on newer Android devices (from API level 26) the modern API comes built-in.Java.time works nicely on both older and newer Android devices. When I run this in Europe/Zurich time zone, the output is:ġ331569860000 Question: Doesn’t java.time require Android API level 26? ![]() Long milliseconds = dateTime.atZone(zone).toInstant().toEpochMilli() LocalDateTime dateTime = LocalDateTime.parse(dateTimeString, formatter) ZoneId zone = ZoneId.systemDefault() ĭateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd.MM.uuuu, H:mm") I recommend you use java.time, the modern Java date and time API, for your date and time work.
