DateTimeFormatter is a new feature of java8 and is thread-safe.

For example, China is Sunday, the United States is SunDateTimeFormatter us = DateTimeFormatter.ofPattern ("EE yyyy-MM-dd hh:mm:ss", Locale.US); String us_format = us.format (datetime); System.out.println (us_format)

DateTimeFormatter comes with many commonly used formatting, such as:

/ / datetime,date,timeLocalDateTime now = LocalDateTime.now (); System.out.println (DateTimeFormatter.ISO_DATE_TIME.format (now)); System.out.println (DateTimeFormatter.ISO_DATE.format (now)); System.out.println (DateTimeFormatter.ISO_TIME.format (now)); / / local datetime,date,timeSystem.out.println (DateTimeFormatter.ISO_LOCAL_DATE_TIME.format (now)); System.out.println (DateTimeFormatter.ISO_LOCAL_DATE.format (now)) System.out.println (DateTimeFormatter.ISO_LOCAL_TIME.format (now)); / / millisecond Instant now_instance = Instant.now (); System.out.println (DateTimeFormatter.ISO_INSTANT.format (now_instance)); this is the end of the introduction to "the use of DateTimeFormatter in java8".
