OffsetDateTime getLong() method in Java with examples
The getLong() method of OffsetDateTime class in Java gets the value of the specified field from this date-time as an long.
Syntax :
public long getLong(TemporalField field)
Parameter: This method accepts a single parameter field which specifies the field to get, not null.
Return Value: It returns the value for the field.
Exceptions: The function throws three exceptions which are described below:
- DateTimeException: it is thrown if a value for the field cannot be obtained or the value is outside the range of valid values for the field.
- UnsupportedTemporalTypeException: it is thrown if the field is not supported or the range of values exceeds an long.
- ArithmeticException: it is thrown if numeric overflow occurs
Below programs illustrate the getLong() method:
Program 1 :
import java.time.OffsetDateTime;
import java.time.temporal.ChronoField;
public class GFG {
public static void main(String[] args)
{
OffsetDateTime date = OffsetDateTime.parse( "2018-12-03T12:30:30+01:00" );
System.out.println(date.getLong(ChronoField.CLOCK_HOUR_OF_DAY));
}
}
|
Program 2 :
import java.time.OffsetDateTime;
import java.time.temporal.ChronoField;
public class GFG {
public static void main(String[] args)
{
try {
OffsetDateTime date = OffsetDateTime.parse( "2018-24-03T12:30:30+01:00" );
System.out.println(date.getLong(ChronoField.CLOCK_HOUR_OF_DAY));
}
catch (Exception e) {
System.out.println(e);
}
}
}
|
Output:
java.time.format.DateTimeParseException:
