How to parse Date from HTTP Last-Modified header?

Question

HTTP Last-Modified header contains date in following format (example):
Wed, 09 Apr 2008 23:55:38 GMT
What is the easiest way to parse java.util.

Answer 1

java.time

When using the new Java Date and Time API the code would simply be:

ZonedDateTime zdt = ZonedDateTime.parse("Wed, 09 Apr 2008 23:55:38 GMT", DateTimeFormatter.RFC_1123_DATE_TIME);

The DateTimeFormatter class pre-defines a constant for that particular format in RFC_1123_DATE_TIME. As the name suggests, RFC 1123 defines that format.
