This article shows how to get current date and time in Java. In the new data and time API from Java 8 onward there are following classes that can be used for displaying either current date, current time or both.
- java.time.LocalDate- To get current date.
- java.time.LocalTime- To get current time.
- java.time.LocalDateTime- To get both current date and time.
- java.time.ZonedDateTime– To get both current date and time with time-zone information.
Other options, mostly applicable, if you are still not using Java 8 version or above are as follows.
- By using java.util.Date class
- By using java.util.Calendar class
1. Current date using LocalDate in Java
Using now() method of the LocalDate you can obtain the current date from the system clock in the default time-zone. For formatting
the date in required format you can use DateTimeFormatter class also added in Java 8.
LocalDate currentDate = LocalDate.now();
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd");
System.out.println(currentDate.format(formatter)); //2020-06-22
2. Current time using LocalTime in Java
Using now() method of the LocalTime class you can obtain the current time from the system clock in the default time-zone.
LocalTime currentTime = LocalTime.now();
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("hh:mm:ss");
System.out.println(currentTime.format(formatter)); //09:54:09
3. Current date and time using LocalDateTime in Java
Using now() method of LocalDateTime class you can get the current date-time from the system clock in the default time-zone.
LocalDateTime currentDateTime = LocalDateTime.now();
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss");
System.out.println(currentDateTime.format(formatter)); //2020-06-22T09:58:46
4. Current date and time with zone information
By using ZonedDateTime you can get zone offset and time-zone information too.
ZonedDateTime currentDateTime = ZonedDateTime.now(ZoneId.of("America/Los_Angeles"));
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss z VV");
System.out.println(currentDateTime.format(formatter)); //2020-06-21T21:32:22 GMT-07:00 America/Los_Angeles
5. Getting Date and Time using java.util.Date
When a new Date object is created it is initialized to represent the time at which it was allocated.
Date date = new Date();
System.out.println("Date- " + date); // Date- Mon Jun 22 10:06:12 IST 2020
For formatting date you can use SimpleDateFormat class.
Date date = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
System.out.println("Date- " + sdf.format(date)); // 2020-06-22 10:07:38
6. Getting Date and Time using java.util.Calendar
In Calendar class there is a getInstance() method that gives the current date and time.
Calendar calendar = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
System.out.println("Date- " + sdf.format(calendar.getTime())); // 2020-06-22 10:10:34
