Example 18 with ChineseCalendar

use of android.icu.util.ChineseCalendar in project j2objc by google.

the class ChineseTest method TestFormat.

/**
 * Test formatting.
 * Q: Why is this in Calendar tests instead of Format tests?
 * Note: This test assumes that Chinese calendar formatted dates can be parsed
 * unambiguously to recover the original Date that was formatted. This is not
 * currently true since Chinese calendar formatted dates do not include an era.
 * To address this will require formatting/parsing of fields from some other
 * associated calendar, as per ICU ticket #9043. This test should be timebombed
 * until that ticket is addressed.
