　　 // Calendar.class// 如果直接設置月份或者星期時請注意±1，使用SimpleDateFormat則無此問題。/** #DAY_OF_WEEK * public final static int SUNDAY = 1; * public final static int MONDAY = 2; * public final static int TUESDAY = 3; * public final static int WEDNESDAY = 4; * public final static int THURSDAY = 5; * public final static int FRIDAY = 6; * public final static int SATURDAY = 7;* * #MONTH public* final static int JANUARY = 0; * public final static int FEBRUARY = 1;* public final static int MARCH = 2; * public final static int APRIL = 3;* public final static int MAY = 4; * public final static int JUNE = 5; * public final static int JULY = 6; * public final static int AUGUST = 7; * public final static int SEPTEMBER = 8; * public final static int OCTOBER = 9;* public final static int NOVEMBER = 10; * public final static int DECEMBER = 11; * public final static int UNDECIMBER = 12;*/

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

field 可以顯示的有：幾月，星期幾

style 可能的樣式：縮寫，全拼，全部

localse 所有可能的時區

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));}

結果：

{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
