我怎麼能在Java字符串獲得價值率的

Question

{ 
"query":{ 
    "count":1, 
    "created":"2014-09-13T07:32:01Z", 
    "lang":"en-US", 
    "results":{ 
    "rate":{ 
     "id":"USDINR", 
     "Name":"USD to INR", 
     "Rate":"60.8075", 
     "Date":"9/13/2014", 
     "Time":"3:23am", 
     "Ask":"60.815", 
     "Bid":"60.80" 
    } 
    } 
} 
} 

我想RATE的值，它是60.80754 到Java中的字符串，請幫助

感謝

試試這個..

JSONObject obj = new JSONObject(string); 
JSONObject query = obj.getJSONObject("query"); 
JSONObject results = query.getJSONObject("results"); 
JSONObject rate_obj = results.getJSONObject("rate"); 
String Rate = rate_obj.getString("Rate");
