getLong() method of the Year class used to gets the value as a long value from this Year for the specified field passed as parameter. This method queries this Year 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 int value then an exception is thrown.
Syntax:
public long getLong(TemporalField field)
Parameters: This method accepts field as parameter which is the field to get.
Return value: This method returns the 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 int.
- ArithmeticException – if numeric overflow occurs.
Below programs illustrate the getLong() method:
Program 1:
// Java program to demonstrate// Year.getLong() method  import java.time.*;import java.time.temporal.*;  public class GFG {    public static void main(String[] args)    {        // create a Year object        Year year = Year.of(2019);          // print instance        System.out.println("Year :"                           + year);          // apply getLong method        long value            = year.getLong(ChronoField.YEAR_OF_ERA);          // print result        System.out.println("YEAR_OF_ERA Field: "                           + value);    }} |
Year :2019 YEAR_OF_ERA Field: 2019
Program 2:
// Java program to demonstrate// Year.getLong() method  import java.time.*;import java.time.temporal.*;  public class GFG {    public static void main(String[] args)    {        // create a Year object        Year year = Year.of(2019);          // print instance        System.out.println("Year :"                           + year);          // apply getLong method        long value            = year.getLong(ChronoField.YEAR);          // print result        System.out.println("YEAR Field: "                           + value);    }} |
Year :2019 YEAR Field: 2019
