Java：如何將帶有月份名稱的字符串轉換為DateTime？

Question

我看到了答案，可以讓我在格式像

"14/02/1952 14:52:22"

通過使用DateTimeFormatter

DateTimeFormatter formatter = DateTimeFormat.forPattern("dd/MM/yyyy HH:mm:ss");
DateTime dt = formatter.parseDateTime(string);

我如何將相同的想法應用於這種格式的字符串：

"Sunday, September 29, 2013 7:59:58 AM PDT"

我在嘗試

DateTimeFormatter formatter = DateTimeFormat.forPattern"EEEE, MMMM dd, yyyy h:mm:ss a zzz";
DateTime dt = formatter.parseDateTime(string);

但它對此有所抱怨。

2018年/ Java 10

String value = "Sunday, September 29, 2013 7:59:58 AM PDT";
String format = "EEEE, MMMM dd, yyyy h:mm:ss a zzz";

DateTimeFormatter formatter = new DateTimeFormatterBuilder()
        .parseCaseInsensitive()
        .appendPattern(format)
        .toFormatter(Locale.US);
ZonedDateTime zdt = ZonedDateTime.parse(value, formatter);
System.out.println(zdt);
System.out.println(zdt.format(formatter));

原始答案

您需要更改期望的格式以滿足SimpleDateFormat指定的要求

String value = "Sunday, September 29, 2013 7:59:58 AM PDT";
String format = "EEEE, MMMM dd, yyyy h:mm:ss a zzz";
SimpleDateFormat sdf = new SimpleDateFormat(format);
try {
    Date date = sdf.parse(value);
    System.out.println(date);
    System.out.println(sdf.format(date));
} catch (ParseException ex) {
    ex.printStackTrace();
}
