我想获取所有使用不同语言的语言环境列表,其中ISO3代码用于标识语言环境的语言。我认为以下代码应该有效。
class ISO3LangComparator implements Comparator<Locale> {
int compare(Locale locale1, Locale locale2) {
locale1.ISO3Language <=> locale2.ISO3Language
}
}
def allLocales = Locale.getAvailableLocales().toList()
def uniqueLocales = allLocales.unique {new ISO3LangComparator()}
// Test how many locales there are with iso3 code 'ara'
def arabicLocaleCount = uniqueLocales.findAll {it.ISO3Language == 'ara'}.size()
// This assertion fails
assert arabicLocaleCount <= 1
