假设您修复了明显的语法错误，则：
String dateStr = "16 Dec 2014" // <== This date is in dd MMM yyyyformatter = new SimpleDateFormat(dd/MM/yyyy); // <== This SDF is in dd/MM/yyyyDate thedate = formatter.parse(dateStr); // <== So how can it be expected to parse?
您要做的就是为您需要解析的格式创建一个解析器，并为您想要的格式创建一个格式化器：
String dateStr = "16 Dec 2014";SimpleDateFormat parser = new SimpleDateFormat("dd MMM yyyy");Date thedate = parser.parse(dateStr);SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");String dateStrReformatted = formatter.format(thedate);
