How do I parse an URL String into Name-Value Collection?

public static Map<String, String> splitQuery(String urlquery) throws UnsupportedEncodingException {
        Map<String, String> query_pairs = new LinkedHashMap<String, String>();
        String[] partStr= urlquery.split("\\?");
        if (partStr.length >1 && partStr[1] != null) {
        String[] pairs = partStr[1].split("&");
        for (String pair : pairs) {
            int idx = pair.indexOf("=");
            query_pairs.put(URLDecoder.decode(pair.substring(0, idx), "UTF-8"), URLDecoder.decode(pair.substring(idx + 1), "UTF-8"));
        }
        }
        return query_pairs;
    }
