 Map<String, Integer> java.util.Calendar.getDisplayNames(int field, int style, Locale locale)

field 可以显示的有：几月，星期几

style 可能的样式：缩写，全拼，全部

localse 所有可能的时区

public static void main(String[] args) {
        Calendar c = Calendar.getInstance();
        System.out.println(c.getDisplayNames(Calendar.DAY_OF_WEEK, Calendar.LONG, Locale.UK));
        System.out.println(c.getDisplayNames(Calendar.DAY_OF_WEEK, Calendar.SHORT, Locale.UK));
        System.out.println(c.getDisplayNames(Calendar.DAY_OF_WEEK, Calendar.ALL_STYLES, Locale.UK));

        System.out.println(c.getDisplayName(Calendar.DAY_OF_WEEK, Calendar.LONG, Locale.UK));

        System.out.println(c.getDisplayNames(Calendar.MONTH, Calendar.LONG, Locale.UK));
        System.out.println(c.getDisplayName(Calendar.MONTH, Calendar.LONG, Locale.UK));
    }

结果：

{Saturday=7, Thursday=5, Monday=2, Tuesday=3, Wednesday=4, Friday=6, Sunday=1}
{Thu=5, Wed=4, Sun=1, Sat=7, Fri=6, Tue=3, Mon=2}
{Thu=5, Thursday=5, Saturday=7, Monday=2, Wed=4, Sun=1, Tuesday=3, Sat=7, Wednesday=4, Fri=6, Tue=3, Mon=2, Friday=6, Sunday=1}
Wednesday
{October=9, January=0, April=3, February=1, August=7, June=5, November=10, July=6, May=4, December=11, March=2, September=8}
June
