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);

API level refers to the Android SDK (which you do not need to care about if you are not programming for Android, as seems to be the case in this question) — personne3000, Sep 24 '14 at 05:44

Have you tried using delete to do this?

Thanks for that. I need to delete it using JAVA. Could you please help me with JAVA code. I tried all API's. Might be I am missing something. – Timothy Rajan Nov 07 '13 at 13:53
No. I am looking for a remove method or something similar. Not able to get it. If this doesnt work, I need to convert the JSONArray to a Normal array and remove. Lot of coding involved. Looking to avoid it. – Timothy Rajan Nov 07 '13 at 14:08

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
