問(wèn)題描述

最簡(jiǎn)單的方法:

String[] namesOfDays = new String[7] {
    "SUN", "MON", "TUE", "WED", "THU", "FRI", "SAT"
};

此方法不使用語(yǔ)言環(huán)境.因此，如果系統(tǒng)語(yǔ)言不是英文，這種方法就不能正常工作.

This method does not use Locale. Therefore, if the system's language is not English, this method does not work properly.

使用 Joda 時(shí)間，我們可以這樣做:

Using Joda time, we can do like this:

String[] namesOfDays = new String[7];
LocalDate now = new LocalDate();

for (int i=0; i<7; i++) {
    /* DateTimeConstants.MONDAY = 1, TUESDAY = 2, ..., SUNDAY = 7 */
    namesOfDays[i] = now.withDayOfWeek((DateTimeConstants.SUNDAY + i - 1) % 7 + 1)
        .dayOfWeek().getAsShortText();
}

但是，此方法使用今天的日期和日歷計(jì)算，這對(duì)于最終目的是無(wú)用的.另外，它有點(diǎn)復(fù)雜.

However, this method uses today's date and calendar calculations, which are useless for the final purpose. Also, it is a little complicated.

有沒(méi)有一種簡(jiǎn)單的方法來(lái)獲取像 "Sun", "Mon", ..., "Sat" 這樣的字符串和系統(tǒng)的默認(rèn)語(yǔ)言環(huán)境?

Is there an easy way to get Strings like "Sun", "Mon", ..., "Sat" with system's default locale?

推薦答案

如果我沒(méi)有誤會(huì)你

 calendar.getDisplayName(Calendar.DAY_OF_WEEK, Calendar.SHORT, Locale.US);

是您正在尋找的.這里 你可以找到文檔，

is what you are looking for. Here you can find the documentation,

或者您也可以使用 getShortWeekdays()

String[] namesOfDays = DateFormatSymbols.getInstance().getShortWeekdays()

這篇關(guān)于在 Java 中，如何使用系統(tǒng)的默認(rèn)語(yǔ)言環(huán)境(語(yǔ)言)獲取星期幾(Sun、Mon、...、Sat)的字符串的文章就介紹到這了，希望我們推薦的答案對(duì)大家有所幫助，也希望大家多多支持html5模板網(wǎng)！
