根据您发送的 wiki，我使用以下代码自行解决了该问题:

private static final List<String> sunWeekendDaysCountries = Arrays.asList(new String[]{"GQ", "IN", "TH", "UG"});
private static final List<String> fryWeekendDaysCountries = Arrays.asList(new String[]{"DJ", "IR"});
private static final List<String> frySunWeekendDaysCountries = Arrays.asList(new String[]{"BN"});
private static final List<String> thuFryWeekendDaysCountries = Arrays.asList(new String[]{"AF"});
private static final List<String> frySatWeekendDaysCountries = Arrays.asList(new String[]{"AE", "DZ", "BH", "BD", "EG", "IQ", "IL", "JO", "KW", "LY", "MV", "MR", "OM", "PS", "QA", "SA", "SD", "SY", "YE"});

public static int[] getWeekendDays(Locale locale) {
    if (thuFryWeekendDaysCountries.contains(locale.getCountry())) {
        return new int[]{Calendar.THURSDAY, Calendar.FRIDAY};
    }
    else if (frySunWeekendDaysCountries.contains(locale.getCountry())) {
        return new int[]{Calendar.FRIDAY, Calendar.SUNDAY};
    }
    else if (fryWeekendDaysCountries.contains(locale.getCountry())) {
        return new int[]{Calendar.FRIDAY};
    }
    else if (sunWeekendDaysCountries.contains(locale.getCountry())) {
        return new int[]{Calendar.SUNDAY};
    }
    else if (frySatWeekendDaysCountries.contains(locale.getCountry())) {
        return new int[]{Calendar.FRIDAY, Calendar.SATURDAY};
    }
    else {
        return new int[]{Calendar.SATURDAY, Calendar.SUNDAY};
    }
}
