This will do it. No JODA dependency:
这将做到。没有 JODA 依赖：
DateFormat formatter = new SimpleDateFormat("EEE, dd MMM yyyy");
formatter.setLenient(false);
String dateStr = "Fri, 27 Dec 2013";
Date date = formatter.parse(dateStr);
Calendar calendar = Calendar.instance();
calendar.setTime(date);
// Get values from calendar.

DateFormat formatter = new SimpleDateFormat("EEE, dd MMM yyyy");
String dateStr = "WED, 27 Dec 2013";
Date date = formatter.parse(dateStr);
Calendar calendar = Calendar.getInstance();
calendar.setTime(date);
// Get values from calendar.
System.out.println(calendar.get(Calendar.DAY_OF_WEEK));//1 indexed starting from Sunday
System.out.println(calendar.get(Calendar.DAY_OF_MONTH));//0 indexed
System.out.println(calendar.get(Calendar.MONTH));//0 indexed
System.out.println(calendar.get(Calendar.YEAR));

Since the day of the week is inconsistent with the date represented, we will cut the string, and remove the day of the week, using substring().
由于星期几与表示的日期不一致，我们将剪切字符串，并使用substring().
public static void main(String argsp[]) {
DateFormat formatter = new SimpleDateFormat("dd MMM yyyy");
formatter.setLenient(false);
String dateStr = "Wed, 27 Dec 2013";
String sub = dateStr.substring(4);
try {
Date date = formatter.parse(sub);
System.out.println(date);
} catch (Exception e) {
e.printStackTrace();
}
}

Take a look at Joda time. It provides lots of methods for parsing dates, and obtaining data from them once they have been parsed.
看看乔达时间。它提供了许多解析日期的方法，并在解析后从中获取数据。
