LocalDateTime Class get() method

  • get() method is available in java.time package.
  • get() method is used to get the value for the given field from this date-time object.
  • get() 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.
  • get() method may throw an exception at the time of returning value for the given field.
    • 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 int get(TemporalField t_field);

Parameter(s):

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

Return value:

The return type of this method is int, it returns the value for the given temporal field from this date-time.

Example:

// Java program to demonstrate the example 
// of get(TemporalField t_field) method 
// of LocalDateTime

import java.time.*;
import java.time.temporal.*;

public class GetOfLocalDateTime {
    public static void main(String args[]) {
        // Instantiates two LocalDateTime
        LocalDateTime da_ti1 = LocalDateTime.parse("2005-10-05T10:10:10");
        LocalDateTime da_ti2 = LocalDateTime.now();

        // Display da_ti1, da_ti2
        System.out.println("LocalDateTime da_ti1 and da_ti2: ");
        System.out.println("da_ti1: " + da_ti1);
        System.out.println("da_ti2: " + da_ti2);

        System.out.println();

        // Here, this method gets the value
        // for the given field from this date-time
        // i.e. we are getting the field value
        // MONTH_OF_YEAR from this da_ti1
        int get_val = da_ti1.get(ChronoField.MONTH_OF_YEAR);

        // Display get_val
        System.out.println("da_ti1.get(ChronoField.MONTH_OF_YEAR): " + get_val);

        // Here, this method gets the value for the
        // given field from this date-time
        // i.e. we are getting the field value
        // MICRO_OF_SECOND from this da_ti2
        get_val = da_ti2.get(ChronoField.MICRO_OF_SECOND);

        // Display get_val
        System.out.println("da_ti2.get(ChronoField.MICRO_OF_SECOND): " + get_val);
    }
}

Output

LocalDateTime da_ti1 and da_ti2: 
da_ti1: 2005-10-05T10:10:10
da_ti2: 2020-06-05T02:20:56.040348

da_ti1.get(ChronoField.MONTH_OF_YEAR): 10
da_ti2.get(ChronoField.MICRO_OF_SECOND): 40348
