Java 8 – MinguoDateの例
このMinguoDateカレンダーシステムは、主に台湾（中華民国…）で使用されています。
(ISO) 1912-01-01 = 1-01-01 (Minguo ROC)
現在の日付をMinguoの日付に変換するには、たとえば、1911の数字で現在の年を減算します。
2016 (ISO) - 1911 = 105 (Minguo ROC)
1. LocalDate→MinguoDate
LocalDateをMinguoDateに変換する完全な例を確認してください
TestMinguoDate.java
package com.example.date;
import java.time.LocalDate;
import java.time.chrono.MinguoDate;
public class TestMinguoDate {
public static void main(String[] args) {
// LocalDate -> MinguoDate
System.out.println("Example 1...");
LocalDate localDate = LocalDate.of(1912, 1, 1);
MinguoDate minguo = MinguoDate.from(localDate);
System.out.println("LocalDate : " + localDate); //1912-01-01
System.out.println("MinguoDate : " + minguo); //1-01-01
// MinguoDate -> LocalDate
System.out.println("\nExample 2...");
MinguoDate minguo2 = MinguoDate.of(105, 8, 24);
//LocalDate localDate = LocalDate.ofEpochDay(minguo2.toEpochDay());
LocalDate localDate2 = LocalDate.from(minguo2);
System.out.println("MinguoDate : " + minguo2); //105-08-24
System.out.println("LocalDate : " + localDate2); //2016-08-24
}
}
