SOmething like this

 public static Map getQueryMap(String query)  
 {  
     String[] params = query.split("&");  
     Map map = new HashMap();  
     for (String param : params)  
     {  
         String name = param.split("=")[0];  
         String value = param.split("=")[1];  
         map.put(name, value);  
     }  
     return map;  
 }  

To iterate the map simply:

 String query = url.getQuery();  
 Map map = getQueryMap(query);  
 Set keys = map.keySet();  
 for (String key : keys)  
 {  
    System.out.println("Name=" + key);  
    System.out.println("Value=" + map.get(key));  
 }
