java.text.ParseException:unparsable date:"Mon,22 Aug 2005 20:21:52 +0200"

Question

我收到了这个错误.

我的代码出了什么问题？

String line = "Date: Mon, 22 Aug 2005 20:21:52 +0200";
String datestring = line.substring(6);
DateFormat dateFormat = new SimpleDateFormat("E, dd MMM yyyy HH:mm:ss ZZZZZ");
Date inputDate = null;

try {
    inputDate = dateFormat.parse(datestring);
} catch (ParseException e) {
    e.printStackTrace();
}

您的系统区域设置不是英文吗？尝试明确指定语言环境:

DateFormat dateFormat = new SimpleDateFormat("E, dd MMM yyyy HH:mm:ss ZZZZZ",
        Locale.US);
