The getLong() method of a LocalTime class helps to get the value for the specified field passed as a parameter from this LocalTime as an long value. This method queries this time for the value of the field and the returned value will always be within the valid range of values for the field. When the field is not supported and method is unable to return long value then an exception is thrown.
Syntax:
public long getLong(TemporalField field)
Parameters: This method accepts a single parameter TemporalField field which is the field to get. It should not be null.
Return value: This method returns the long value for the field.
Exception: This method throws following exceptions:
- DateTimeException: if a value for the field cannot be obtained or the value is outside the range of valid values for the field.
- UnsupportedTemporalTypeException: if the field is not supported or the range of values exceeds an long.
- ArithmeticException: if numeric overflow occurs.
Below programs illustrate the getLong() method:
Program 1:
Java
// Java program to demonstrate// LocalTime.getLong() methodimport java.time.*;import java.time.temporal.ChronoField;public class GFG { public static void main(String[] args) { // create a LocalTime object LocalTime time = LocalTime.parse("19:34:50.63"); // get Mili of Second value from LocalTime // using get method long secondvalue = time.getLong(ChronoField.MILLI_OF_SECOND); // prlong result System.out.println("MilliSecond Field: " + secondvalue); }} |
MilliSecond Field: 630
Program 2: To get UnsupportedTemporalTypeException
Java
// Java program to demonstrate// LocalTime.getLong() methodimport java.time.*;import java.time.temporal.ChronoField;public class GFG { public static void main(String[] args) { // create a LocalTime object LocalTime time = LocalTime.parse("19:34:50.63"); // try to find era using ChronoField try { long secondvalue = time.getLong(ChronoField.YEAR); } catch (Exception e) { // prlong exception System.out.println("Exception: " + e); } }} |
Exception: java.time.temporal.UnsupportedTemporalTypeException: Unsupported field: Year
