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

在 java-json 中,没有直接删除 jsonObject 的方法,但是使用json-simple很简单:
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);

只需获取json数组中JSON对象的索引
并通过 array.splice(index,howmany,item1,.....,itemX) 方法删除 json 对象
有关更多信息,请使用此链接 http://www.w3schools.com/jsref/jsref_splice.asp

您是否尝试过使用删除来执行此操作?
