在上面的示例中，我们使用SimpleDateFormat类来格式化时间。我们获取当前时间now，然后创建一个SimpleDateFormat对象sdf，并指定日期格式为"yyyy-MM-dd HH:mm:ss"。最后，我们使用sdf.format(now)方法将时间格式化为指定格式的字符串，并将其存储在formattedTime变量中。最后，我们将格式化后的时间输出到控制台。使用时...

SimpleDateFormatallows you to start by choosing any user-defined patterns for date-time formatting. However, you are encouraged to create a date-time formatter with eithergetTimeInstance,getDateInstance, orgetDateTimeInstanceinDateFormat. Each of these class methods can return a date/time formatter ini...
The main date-time classes provide two methods - one for formatting,format(DateTimeFormatter formatter), and one for parsing,parse(CharSequence text, DateTimeFormatter formatter). For example: <blockquote> text/java複製 LocalDate date = LocalDate.now(); String text = date.format(formatter); Local...
