JapaneseDate getLong() method in Java with Example

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.

Syntax:

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
