这样的Exception该怎么解决

  public static void main(String[] args) throws Exception {    String[] urls = {        "http://mil.news.sina.com.cn/2012-04-10/0428687123.html",        "http://mil.news.sina.com.cn/2012-04-12/0731687387.html",        "http://news.sina.com.cn/c/2012-04-13/044224264609.shtml"    };    final Pattern titlePattern = Pattern        .compile("<h1 id=\"artibodyTitle\".*?>(.*?)</h1>");    final Pattern wordCountPattern = Pattern.compile("\u515a|\u56fd\u5bb6");    for (final String url : urls) {      new Thread() {        public void run() {          BufferedReader reader = null;          try {            reader = new BufferedReader(new InputStreamReader(                new URL(url).openStream(), "GB2312"));            String line;            String title = null;            int[] count = new int[2];            while ((line = reader.readLine()) != null) {              if (title == null) {                Matcher titleMatcher = titlePattern.matcher(line);                if (titleMatcher.find()) {                  title = titleMatcher.group(1);                }              }              Matcher wordCountMatcher = wordCountPattern.matcher(line);              while (wordCountMatcher.find()) {                String word = wordCountMatcher.group();                count[word.length() >> 1]++;              }            }            if (count[0] > count[1]) {              throw new RuntimeException(                  String.format("%s[%s] \u515a:%d > \u56fd\u5bb6:%d",                                title,                                url,                                count[0],                                count[1]));            }            System.out.printf("%s[%s] is good!", title, url);          } catch (IOException ex) {            ex.printStackTrace();          } finally {            if (reader != null) {              try {                reader.close();                reader = null;              } catch (Exception ex) {              }            }          }        }      }.start();    }  }
