Can't Convert string to JsonArray

How do you convert this String into gson.JsonArray?

String s= "[["110917    ", 3.0099999999999998, -0.72999999999999998, 2.8500000000000001, 2.96, 685.0, 38603.0], ["110917    ", 2.71, 0.20999999999999999, 2.8199999999999998, 2.8999999999999999, 2987.0, 33762.0]]";

This is my Code:

 com.google.gson.*;
 public static void main(String[] args)
   {
       //Declared S here
       System.out.println("String to Json Array Stmt");
       JsonParser parser = new JsonParser();
       JsonElement tradeElement = parser.parse(s.toString());
       JsonArray trade = tradeElement.getAsJsonArray();
       System.out.println(trade);
    }

Is this the way to convert this Collections string to JSonArray?
