The date() method of java.time.chrono.JapaneseChronology class is used get the japanese date according to Japanese calendar system from the another TemporalAccessor object . Syntax:
public JapaneseDate date(TemporalAccessor temporal)
Parameter: This method takes the object of any temporal accessor as a parameter. Return Value: This method returns the local date according to the Japanese calendar system from another TemporalAccessor object. Below are the examples to illustrate the date() method: Example 1:
// Java program to demonstrate
// date() method
  
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
  
public class GFG {
    public static void main(String[] argv)
    {
        try {
            // creating and initializing
            // JapaneseDate Object
            JapaneseDate hidate = JapaneseDate.now();
  
            // getting JapaneseChronology
            // used in JapaneseDate
            JapaneseChronology crono
                = hidate.getChronology();
  
            // creating and initializing
            // TemporalAccessor object
            ZonedDateTime zonedate
                = ZonedDateTime.parse(
                    "2018-10-25T23:12:31."
                    + "123+02:00[Europe/Paris]");
  
            // getting JapaneseDate for the
            // given TemporalAccessor object
            // by using date() method
            JapaneseDate date = crono.date(zonedate);
  
            // display the result
            System.out.println("JapaneseDate is: " + date);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: " + e);
        }
    }
}

public class GFG {
    public static void main(String[] argv)

        try {
            // creating and initializing
            // JapaneseDate Object
            JapaneseDate hidate
                = JapaneseDate.now();
  
            // getting JapaneseChronology
            // used in JapaneseDate
            JapaneseChronology crono
                = hidate.getChronology();
  
            // creating and initializing
            // TemporalAccessor object
            LocalDateTime localdate
                = LocalDateTime
                      .parse("2018-12-30T19:34:50.63");
  
            // getting JapaneseDate for the
            // given TemporalAccessor object
            // by using date() method
            JapaneseDate date = crono.date(localdate);
  
            // display the result
            System.out.println("JapaneseDate is: " + date);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: " + e);
        }
    }
}
