  • Last Updated : 27 Mar, 2020

The getLong() method of java.time.chrono.JapaneseDate class is used to retrieve the passed temporal field in long format.

public long getLong(TemporalField field)

Parameter: This method takes any type of temporal field as a parameter.

Return Value: This method returns the passed temporal field in long format.

Below are the examples to illustrate the getLong() method:



Example 1:

Java




// Java program to demonstrate
// getLong() method
  
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.*;
  
public class GFG {
    public static void main(String[] argv)
    {
        try {
  
            // creating and initializing
            // JapaneseDate Object
            JapaneseDate hidate
                = JapaneseDate.now();
  
            // getting temporal field in long format
            // by using getLong() method
            long tempo
                = hidate.getLong(
                    ChronoField.EPOCH_DAY);
  
            // display the result
            System.out.println(
                "specified temporal field"
                + "in long format: "
                + tempo);
        }
        catch (DateTimeException e) {
            System.out.println(
                "passed parameter can"
                + " not form a date");
            System.out.println(
                "Exception thrown: "
                + e);
        }
    }
}
Output:
specified temporal fieldin long format: 18336

Example 2:

Java




// Java program to demonstrate
// getLong() method
  
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.*;
  
public class GFG {
    public static void main(String[] argv)
    {
        try {
  
            // creating and initializing
            // JapaneseDate Object
            JapaneseDate hidate
                = JapaneseDate.now();
  
            // getting temporal field in long format
            // by using getLong() method
            long tempo
                = hidate.getLong(
                    ChronoField.DAY_OF_WEEK);
  
            // display the result
            System.out.println(
                "specified temporal field"
                + "in long format: "
                + tempo);
        }
        catch (DateTimeException e) {
            System.out.println(
                "passed parameter can"
                + " not form a date");
            System.out.println(
                "Exception thrown: "
                + e);
        }
    }
}
Output:
specified temporal fieldin long format: 7
