MonthDay getLong() method in Java with Examples

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 exptions 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:

// Program to illustrate the getLong() method 
  
import 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:

Program 2:

// Program to illustrate the getLong() method 
  
import 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:

Program 3: To demonstrate DateTimeParseException

// Program to illustrate the getLong() method 
  
import 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
