Java JapaneseDate類使用實例

實例1: test_getDayOfYear

import java.time.chrono.JapaneseDate; //導入依賴的package包/類@Testpublic void test_getDayOfYear() {    // Test all the Eras    for (JapaneseEra era : JapaneseEra.values()) {        int firstYear = (era == JapaneseEra.MEIJI) ? 6 : 1;  // Until Era supports range(YEAR_OF_ERA)        JapaneseDate hd1 = JapaneseChronology.INSTANCE.dateYearDay(era, firstYear, 1);        ValueRange range = hd1.range(DAY_OF_YEAR);        assertEquals(range.getMaximum(), hd1.lengthOfYear(), "lengthOfYear should match range.getMaximum()");        for (int i = 1; i <= hd1.lengthOfYear(); i++) {            JapaneseDate hd = JapaneseChronology.INSTANCE.dateYearDay(era, firstYear, i);            int doy = hd.get(DAY_OF_YEAR);            assertEquals(doy, i, "get(DAY_OF_YEAR) incorrect for " + i + ", of date: " + hd);        }    }}
