Java中字符串和Date类型相互转换

字符创转Date：

Date date =null;

try {

SimpleDateFormatsdf = new SimpleDateFormat("yyyy-MM-dd");

StringstrDate = "2012-3-1";

date =sdf.parse(strDate);

} catch (ParseException e){

e.printStackTrace();

}

Date转字符串：

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");

String date = sdf.format(newDate());
