BlackBerry的当前日期

Question

我正在开发一个需要设备当前日期的应用程序，但它只需要星期几，月份和日期，例如Friday October 14

我在日历中尝试过这段代码。如何将Date转换为String？这可能以这种格式获取日期吗？

 Calendar c = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
 System.out.println("Date" + c.getTime());

 and my output : `Fri Oct 14 16:17:03 Asia/Calcutta 2011`

Answer 1

您可以使用SimpleDateFormat：

SimpleDateFormat fmt = new SimpleDateFormat("EEEE MMMM dd");
Calendar c = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
System.out.print("Date ");
System.out.println(fmt.format(c.getTime()));

如果你需要不同字符串中的那些值，它会变得更复杂一些（使用DateFormatSymbols来获取月/工作日名称）：

Calendar c = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
DateFormatSymbols dateSymbols = new DateFormatSymbols();
String[] monthsText = dateSymbols.getMonths();
String[] weekdaysText = dateSymbols.getWeekdays();

String day = String.valueOf(c.get(Calendar.DAY_OF_MONTH));
String month = monthsText[c.get(Calendar.MONTH)];
String weekday = weekdaysText[c.get(Calendar.DAY_OF_WEEK)];

System.out.format("day: %s, month: %s, weekday: %s", day, month, weekday);
