DateTimeParseException：无法在索引 2 处解析文本

Question

我现在真的很困惑为什么以下代码段会导致 DateTimeParseException。public static void main(String[] args) {        java.time.format.DateTimeFormatter dtf = java.time.format.DateTimeFormatter.ofPattern("EEE, dd MMM yyyy HH:mm:ss zzz");        String date = "Mon, 10 Sep 2018 23:57:09 UTC";        System.out.println(dtf.parse(date));}抛出以下异常：Exception in thread "main" java.time.format.DateTimeParseException: Text 'Mon, 10 Sep 2018 23:57:09 UTC' could not be parsed at index 2    at java.time.format.DateTimeFormatter.parseResolved0(DateTimeFormatter.java:1949)    at java.time.format.DateTimeFormatter.parse(DateTimeFormatter.java:1777)    at com.sample.binding.bitronvideo.driver.BitronVideoRecordingDriver.main(BitronVideoRecordingDriver.java:448)我真的很感激进一步的帮助。
