title: Regular Expression named capturing groups support in Java 7
body: <p>Since Java 7 regular expressions API offers support for named capturing groups.
  The method <a href="http://docs.oracle.com/javase/8/docs/api/java/util/regex/Matcher.html#group-java.lang.String-" rel="noreferrer">java.util.regex.Matcher.group(String)</a> returns the input subsequence captured by the given named-capturing group, but there's no example available on API documentations.</p>
  
  <p>What is the right syntax to specify and retrieve a named capturing group in Java 7?</p>
