Java is the most popular programming language and widely used programming language. Java is used in all kind of application like mobile application, desktop application, web application. In this Java java.time.OffsetDate, Time class is imported which is an immutable representation of a date-time with an offset. This class stores all date and time fields, to a precision of nanoseconds, as well as the offset from UTC. For example, the value “22nd February 2021 at 01:55.19.123456789 +02:00” can be stored in an OffsetDateTime.

Methods |
Description |
|---|---|
| adjustInto(Temporal temporal) | This method adjusts the specified temporal object to have the same offset, date and time as this object. |
| atZoneSameInstant(ZoneId zone) | This method combines this date-time with a time-zone to create a ZonedDateTime ensuring that the result has the same instant. |
| atZoneSimilarLocal(ZoneId zone) | This method combines this date-time with a time-zone to create a ZonedDateTime trying to keep the same local date and time. |
| compareTo(OffsetDateTime other) | This method compares this date-time to another date-time. |
| equals(Object obj) | It is used to checks if this date-time is equal to another date-time. |
| getMonth() | It is a method that is used to display the current month. |
| now() | It is a method used to obtain the current date and time from the system clock. |
| getYear() | It is a method that is used to display the current Year. |
| getDayOfWeek() | It is a method that is used to display the current day of the week. |
| getHour() | It is a method that is used to display a specific hour. |
| getMinute() | It is a method that is used to display a specific minute. |
| getNano() | It is a method that displays a specific nanosecond. |
| getSecond() | It is a method that displays a specific second. |
| equals(Object obj) | This method checks if this date-time is equal to another date-time. |
| format(DateTimeFormatter formatter) | This method formats this date-time using the specified formatter. |
| from(TemporalAccessor temporal) | This method obtains an instance of OffsetDateTime from a temporal object. |
| get(TemporalField field) | This method gets the value of the specified field from this date-time as an int. |
| hashCode() | A hash code for this date-time. |
| isAfter(OffsetDateTime other) | This method checks if the instant of this date-time is after that of the specified date-time. |
| isBefore(OffsetDateTime other) | This method checks if the instant of this date-time is before that of the specified date-time. |
| isEqual(OffsetDateTime other) | This method checks if the instant of this date-time is equal to that of the specified date-time. |
| isSupported(TemporalField field) | This method checks if the specified field is supported. |
| isSupported(TemporalUnit unit) | This method checks if the specified unit is supported. |
| withMinute(int minute) | This method returns a copy of this OffsetDateTime with the minute-of-hour altered. |
| withYear(int year) | This method returns a copy of this OffsetDateTime with the year altered. |
| minusDays(long days) | This method returns a copy of this OffsetDateTime with the specified number of days subtracted. |
| minusHours(long hours) | This method returns a copy of this OffsetDateTime with the specified number of hours subtracted. |
| minusMinutes(long minutes) | This method returns a copy of this OffsetDateTime with the specified number of minutes subtracted. |
| minusMonths(long months) | This method returns a copy of this OffsetDateTime with the specified number of months subtracted. |
| minusNanos(long nanos) | This method returns a copy of this OffsetDateTime with the specified number of nanoseconds subtracted. |
| minusSeconds(long seconds) | This method returns a copy of this OffsetDateTime with the specified number of seconds subtracted. |
| minusWeeks(long weeks) | This method returns a copy of this OffsetDateTime with the specified number of weeks subtracted. |
| minusYears(long years) | This method returns a copy of this OffsetDateTime with the specified number of years subtracted. |
| range(TemporalField field) | This method gets the range of valid values for the specified field. |
| timeLineOrder() | This method gets a comparator that compares two OffsetDateTime instances based solely on the instant. |
Below is the implementation of the problem statement: Year/ Month/ Day format
Java
// import java.time.OffsetDateTime classimport java.time.OffsetDateTime; public class gfg1 { public static void main(String[] args) { // now() is a method used to obtain current // date and time from the system clock. OffsetDateTime offsetDateTime = OffsetDateTime.now(); // Display the offsetDateTime which will // display all current date and time. System.out.println(offsetDateTime); // Display Year, Month and Day using methods System.out.println( "Year : " + offsetDateTime.getYear() + "| Month : " + offsetDateTime.getMonth() + " |Day : " + offsetDateTime.getDayOfWeek()); }} |
Output
2021-02-22T17:53:28.809568Z Year : 2021| Month : FEBRUARY |Day : MONDAY
Below is the implementation of the problem statement: Hour/ Minute/ Second/ NanoSecond format
Java
// import java.time.OffsetDateTime classimport java.time.OffsetDateTime; public class gfg1 { public static void main(String[] args) { // now() is a method used to obtain current // date and time from the system clock. OffsetDateTime offsetDateTime = OffsetDateTime.now(); // Display the offsetDateTime which will // display all current date and time. System.out.println(offsetDateTime); // Display the Hour,Minute, Second and // Nanosecond using getHour(), getMinute(), // getSecond() and getNano() System.out.println( "Hour : " + offsetDateTime.getHour() + " Minute : " + offsetDateTime.getMinute() + " Second : " + offsetDateTime.getSecond() + " NanoSecond : " + offsetDateTime.getNano()); }} |
Output
2021-02-22T17:53:28.315232Z Hour : 17 Minute : 53 Second : 28 NanoSecond : 315232000
