Below are the examples to illustrate the dateYearDay() method:
Example 1:
Java
// Java program to demonstrate// dateYearDay() methodimport 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(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); } }} |
Output:
JapaneseDate is: Japanese Heisei 30-01-24
Example 2:
Java
// Java program to demonstrate// dateYearDay() methodimport 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(1440, 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); } }} |
Output:
passed parameter can not form a date Exception thrown: java.time.DateTimeException: JapaneseDate before Meiji 6 is not supported
