範例1：

Java

// Java program to demonstrate 
// dateYearDay() 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(); 
  
            // getting JapaneseDate for the 
            // given date and year field 
            // by using dateYearDay() method 
            JapaneseDate date 
                = crono.dateYearDay( 
                    JapaneseEra.HEISEI, 
                    2018, 
                    24); 
  
            // 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); 
        } 
    } 
}

輸出：

JapaneseDate is:Japanese Heisei 2018-01-24
