In Java 8, you can use the DateTimeFormatter class to convert String to LocalDate, LocalTime or LocalDateTime. Unlike SimpleDateFormat, the DateTimeFormatter is immutable and thread-safe and you can use it as a static variable for sharing and reuse. It also comes with pre-defined date time format e.g. ISO-8601 format. The ISO_LOCAL_DATE_TIME formats or parses a date-time without an offset, such as '2016-03-04T10:15:30'.
