title: Java regex: check if word has non alphanumeric characters
body: <p>This is my code to determine if a word contains any non-alphanumeric characters:</p>
  
  <pre><code>  String term = "Hello-World";
    boolean found = false;
    Pattern p = Pattern.Compile("\\W*");
    Matcher m = p.Matcher(term);
    if(matcher.find())
      found = true;
  </code></pre>
  
  <p>I am wondering if the regex expression is wrong. I know <code>"\W"</code> would matches any non-word characters. Any idea on what I am missing ??</p>
