Change the `formatPattern` string to match the desired format for date and time. This example will produce an output in the format of “ 19:48:30” (assuming this is the current date and time). We can use DateTimeFormatter class ofPattern() method to create a DateTimeFormatter object with the specified format pattern. ![]() Finally, we format the date and time using the `format()` method and print the result. Formatting Date and Time The 'T' in the example above is used to separate the date from the time. Then, we define a custom format pattern (`”yyyy-MM-dd HH:mm:ss”`) and create a `DateTimeFormatter` using the `DateTimeFormatter.ofPattern()` method. You can also put timezone information in formatted Date using Z attribute of DateFormat class. You can format date on any String format based upon various attribute available in SimpleDateFormat class e.g. In this example, we first get the current date and time using `LocalDateTime.now()`. SimpleDateFormat in Java is used to format Date in Java. DateTimeFormatter, Formatter for displaying and parsing date-time objects. ![]() The way of writing date is different in different regions of the world. LocalDateTime, Represents both a date and a time (yyyy-MM-dd-HH-mm-ss-ns). The locale is used for specifying the region and language for making the code more locale to the user. Date/Time for Java types which are capable of encoding a date or time: long, Long, Calendar, Date and TemporalAccessor. String formattedDate = now.format(formatter) Java DateFormat DateFormat is used for formatting a date into String based on specific locale that is provided as input. Java provides an extensive API for handling date and time. Format the date and time using the DateTimeFormatter Create a DateTimeFormatter with the custom patternĭateTimeFormatter formatter = DateTimeFormatter.ofPattern(formatPattern) String formatPattern = "yyyy-MM-dd HH:mm:ss" Define a custom date and time format pattern There are two classes for formatting dates in Java: DateFormat and SimpleDateFormat. In Java, you can format a date and time using the `` class, which is available in Java 8 and later versions. Basically, DateTimeFormatter provides the format () method to do the job. 8 Answers Sorted by: 76 java.time EDIT: DateTimeFormatter.ofPattern ('EEE, dd MMM yyyy HH:mm:ss z', Locale.ENGLISH).withZone (ZoneId. Fortunately for us, Java 8 introduced the DateTimeFormatter class to uniformly format dates and times. In this example, we get the current date and time using `LocalDateTime.now()`, define a custom format pattern (e.g., “yyyy-MM-dd HH:mm:ss”), create a DateTimeFormatter with that pattern using `DateTimeFormatter.ofPattern()`, then use the formatter’s `format()` method to produce an output string matching our specified format – for instance, “ 19:48:30”. Using the DateTimeFormatter Class Generally speaking, well need a formatter to format an Instant object. It can be written as ‘c’ or ’C’ based on the case we want.Using the `` class, available in Java 8 and later versions, you can easily format a date and time to match your desired output pattern. This conversion can also be used for the types int and Integer when the Character.isValidCodePoint(int) returns true for them. Used for the basic types which represent Unicode characters: char, Character, byte, Byte, short, and Short.
