title: Constructing regex pattern to match sentence
body: <p>I'm trying to write a regex pattern that will match any sentence that begins with multiple or one tab and/or whitespace.
  For example, I want my regex pattern to be able to match "    hello there I like regex!" 
  but so I'm scratching my head on how to match words after "hello". So far I have this:</p>
  
  <pre><code>    String REGEX = "(?s)(\\p{Blank}+)([a-z][ ])*";
      Pattern PATTERN = Pattern.compile(REGEX);
      Matcher m = PATTERN.matcher("         asdsada  adf adfah.");
      if (m.matches()) {
          System.out.println("hurray!");
      }
  </code></pre>
  
  <p>Any help would be appreciated. Thanks.</p>
