回答by Fortega
now.toString()is not a good way to represent a date as a string, because it uses a 'default' format. To represent a date to a string, you can use the format(Date date)method of SimpleDateFormat:
now.toString()不是将日期表示为字符串的好方法，因为它使用“默认”格式。要将日期表示为字符串，您可以使用以下format(Date date)方法SimpleDateFormat：
SimpleDateFormat sdf = new SimpleDateFormat("dd.MM.yyyy");
Date now = new Date();
String dateAsString = sdf.format(date); //"08.01.2013"
Date dateFromString = sdf.parse(dateAsString);
