Remove JSON object from JSONArray - Jettison

问题:

Is there a direct way to remove an JSONObject stored in the JSONArray by using index. I tried all the possibilities. Still not able to remove the JSON object from the JSON Array. Any hint will be helpful Thanks

In java-json , there is no direct method to remove jsonObject, but using json-simple , it is simple to do so:

        JSONArray jsonArray = new JSONArray();         JSONObject jsonObject = new JSONObject();         JSONObject jsonObject1 = new JSONObject();         JSONObject jsonObject2 = new JSONObject();         jsonObject.put("key1", "value1");         jsonObject1.put("key2", "value2");         jsonObject2.put("key3", "value3");         jsonArray.add(jsonObject);         jsonArray.add(jsonObject1);         jsonArray.add(jsonObject2);          //........ Whole Json Array         System.out.println(jsonArray);           //To remove 2nd jsonObject (index starts from 0)          jsonArray.remove(1);           // Now the array will not have 2nd Object         System.out.println(jsonArray);

Have you tried using delete to do this?

just get the index of the JSON object in the json array

and remove the json object by array.splice(index,howmany,item1,.....,itemX) method

for more information just use this link http://www.w3schools.com/jsref/jsref_splice.asp
