The getLong() method of MonthDay class in Java gets the value of the specified field from this month-day as an long. Syntax:
public long getLong(TemporalField field)
Parameter: This method accepts a parameter field which specifies the field to getLong and not null. Returns: The function returns the long value for the field. Exceptions: The function throws three exceptions as described below:
- DateTimeException: this is thrown when 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 when the field is not supported or the range of values exceeds an long
- ArithmeticException: thrown when a numeric overflow occurs.
Below programs illustrate the MonthDay.getLong() method: Program 1:
Java
// Program to illustrate the getLong() methodimport java.util.*;import java.time.*;import java.time.temporal.ChronoField;public class GfG { public static void main(String[] args) { // Parses the date MonthDay tm1 = MonthDay.parse("--10-12"); System.out.println( tm1.getLong(ChronoField.DAY_OF_MONTH)); }} |
Output:
12
Program 2:
Java
// Program to illustrate the getLong() methodimport java.util.*;import java.time.*;import java.time.temporal.ChronoField;public class GfG { public static void main(String[] args) { // Parses the date MonthDay tm1 = MonthDay.parse("--12-06"); System.out.println( tm1.getLong( ChronoField.DAY_OF_MONTH)); }} |
Output:
6
Program 3: To demonstrate DateTimeParseException
Java
// Program to illustrate the getLong() methodimport java.util.*;import java.time.*;import java.time.temporal.ChronoField;public class GfG { public static void main(String[] args) { try { // Parses the date MonthDay tm1 = MonthDay.parse("--13-12"); System.out.println( tm1.getLong( ChronoField.DAY_OF_MONTH)); } catch (Exception e) { System.out.println(e); } }} |
Output:
java.time.format.DateTimeParseException:
Text '--13-12' could not be parsed:
Unable to obtain MonthDay from TemporalAccessor:
{DayOfMonth=12, MonthOfYear=13},
ISO of type java.time.format.Parsed
