Below are the examples to illustrate the from() method:
Example 1: 



Java




// Java program to demonstrate from() 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
            // TemporalAccessor object
            ZonedDateTime zonedate
                = ZonedDateTime
                      .parse(
                          "2018-10-25T23:12:31."
                          + "123+02:00[Europe/Paris]");
 
            // Creating and initializing
            // JapaneseDate Object
            JapaneseDate hidate
              = JapaneseDate.from(zonedate);
 
            // Display the result
            System.out.println("JapaneseDate: "
                               + hidate);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: "
                               + e);
        }
    }
}
Output
JapaneseDate: Japanese Heisei 30-10-25

 

Example 2:

Java




// Java program to demonstrate from() 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
            // TemporalAccessor object
            LocalDateTime localdate
                = LocalDateTime.parse(
                    "2018-12-30T19:34:50.63");
 
            // Creating and initializing
            // JapaneseDate Object
            JapaneseDate hidate
              = JapaneseDate.from(localdate);
 
            // Display the result
            System.out.println("JapaneseDate: "
                               + hidate);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
