LocalDate Class getLong() method

  • getLong() method is available in java.time package.
  • getLong() method is used to get the value as long for the given temporal field from this LocalDate.
  • getLong() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
  • getLong() method may throw an exception at the time of returning value as long.
    • DateTimeException: This exception may throw when the given field couldn't be generated.
    • UnsupportedTemporalTypeException: This exception may throw when the given field is unsupported.
    • ArithmeticException: This exception may throw when the calculated result exceeds the limit.

Syntax:

    public long getLong(TemporalField t_field);

Parameter(s):

  • TemporalField t_field – represents the field of the returned value.

Return value:

The return type of this method is long, it gets the value of the given field in a long from this LocalDate.

Example:

// Java program to demonstrate the example // of getLong(TemporalField t_field) method // of LocalDate import java.time.*; import java.time.temporal.*; public class GetLongOfLocalDate { public static void main(String args[]) { // Instantiates two LocalDate LocalDate l_da1 = LocalDate.parse("2007-04-04"); LocalDate l_da2 = LocalDate.now(); // Display l_da1,l_da2 System.out.println("LocalDate l_da1 and l_da2: "); System.out.println("l_da1: " + l_da1); System.out.println("l_da2: " + l_da2); System.out.println(); // Here, this method gets the value as long // for the given field YEAR from this // date l_da1 long get_val = l_da1.getLong(ChronoField.YEAR); // Display get_val System.out.println("l_da1.getLong(ChronoField.YEAR): " + get_val); // Here, this method gets the value as long // for the given field DAY_OF_WEEK // from this date l_da2 get_val = l_da2.getLong(ChronoField.DAY_OF_WEEK); // Display get_val System.out.println("l_da2.getLong(ChronoField.DAY_OF_WEEK): " + get_val); } }

Output

LocalDate l_da1 and l_da2: 
l_da1: 2007-04-04
l_da2: 2020-05-30

l_da1.getLong(ChronoField.YEAR): 2007
l_da2.getLong(ChronoField.DAY_OF_WEEK): 6
