Java pattern matching

case insensitive search for a string

      Properties properties = System.getProperties();
      properties.list(System.out);
      String osname = (String)properties.get("os.name");
      System.out.println("osname="+osname);
     
      Pattern pat = Pattern.compile("Windows", Pattern.CASE_INSENSITIVE);
      Matcher mat = pat.matcher(osname);

      System.out.println("Looking for windows in windows xp.");

      if (mat.find())
        System.out.println("subsequence found");
      else
        System.out.println("No Match");
