Answer 1

Simple Solution create the map out of all param name and values and use it :).

import org.apache.commons.lang3.StringUtils;

    public String splitURL(String url, String parameter){
                HashMap urlMap=new HashMap();
                String queryString=StringUtils.substringAfter(url,"?");
                for(String param : queryString.split("&")){
                    urlMap.put(StringUtils.substringBefore(param, "="),StringUtils.substringAfter(param, "="));
                }
                return urlMap.get(parameter);
            }
