Unlike DateFormat and SimpleDateFormat of old date and time API, this class is both immutable and thread-safe, and you can also store it into a static variable. As I said, you can use the class for parsing and formatting String in Java 8. That's all about how to convert String to LocalDateTime in Java 8. Here is another example of formatting dates in Java 8: ![]() It's a short course, and you can learn all new Java 8 features in a quick time, which will help you to write better code In Java. If you want to learn more, I suggest you take a look at the What's New in Java 8 course on Pluralsight. It's packed with powerful features which makes date and time-related task really easy in Java application. ![]() These are just the tip of the iceberg of what you can do with the new Date and Time API of Java 8. If you print or query this LocalDateTime instance, you will find that all date parts like the year, month, date, hour, and seconds are as per the given input String.ītw, If your String contains seconds as well like " 11:30: 40", then you can change your date time format to yyyy-MM-dd HH:mm:ss" as shown below:ĭateTimeFormatter formatter = DateTimeFormatter.ofPattern( "yyyy-MM-dd HH:mm:ss") LocalDateTime dateTime = LocalDateTime.parse(str, formatter) ĭone, that's all is required to convert a formatted String to transform into a LocalDateTime. If you are new to formatting instructions, you can see the Javadoc for a complete list.ĭateTimeFormatter formatter = DateTimeFormatter.ofPattern( "yyyy-MM-dd HH:mm") ![]() You can also use predefined date formats like ISO_LOCAL_DATE_TIME or can specify by yourself as String into the second parameter. The DateTimeFormatter argument is used to specify the date/time pattern. It takes a String and a DateTimeFormatter as a parameter. In order to create a LocalDateTime object from a string, you can use the static LocalDateTime.parse() method. ![]() In this article, I'll show you how to convert a String to LocalDateTime in Java 8, and then back to a formatted string, but you can also check out The Complete Java MasterClass to learn more about the new Date and Time API, which is quite vast.Ĭonverting String to LocalDateTime in Java - Example The ISO_LOCAL_DATE_TIME formats or parses a date-time without an offset, such as 'T10:15:30'. It also comes with a pre-defined date-time format like ISO-8601 format. Unlike SimpleDateFormat, the DateTimeFormatter class is both immutable and thread-safe, and you can use it as a static variable for sharing and reuse. In Java 8 and beyond, you can use the DateTimeFormatter class to convert String to LocalDate, LocalTime, or LocalDateTime class of Java 8 Date Time API, which represents date, time, and date-time data types. Suppose you have a date-time String ": 11:01:20" and you want to convert this into a LocalDateTime object of Java 8 new date and time API, how do you do that? Well, if you have worked previously with String and Date then you know that you can parse String to Date in Java.īefore Java 8, Java developers used to use SimpleDateFormat, which was mutable and not thread-safe and advised not to be shared between threads. I had discussed this before (see the Date to String) when Java 8 was not out, but with Java 8, I don't see any reason to use old date and time API, and hence I am writing this post to teach you how to convert String to Date in Java 8 or beyond. Hello guys, today, I will talk about a common problem while working in a Java application, yes you guessed it right, I am talking about String to Date conversion in Java. ![]()
