I want to cast a JSONTokener to JSONArray and JSONObject, I know that is very simple and i did some search on but sample codes doesn't work for me,what is wrong?
StringBuilder builder= new StringBuilder();
//some codes to fill my StringBuilder
JSONTokener tokener = new JSONTokener( builder.toString() );
JSONArray finalResult = new JSONArray( tokener );
//error: Unhandle exeception:org.json.JsonExeception
or
JSONObject myJSONObject=new JSONObject(tokener)
//error: Unhandle exeception:org.json.JsonExeception
What is wrong with this codes ?
Don't try to create JSONObject from tokener. Simply cast its .nextValue()
.
From the official example:
JSONObject object = (JSONObject) new JSONTokener(json).nextValue();
String query = object.getString("query");
JSONArray locations = object.getJSONArray("locations");
