how to merge json array using java? [duplicate]

Question

I am working on android studio.

I have two json arrays such as...

jsonArray1:

[
  {"file":"ay.m4a", "version":"5"}, 
  {"file":"kt.m4a", "version":"5"}
]

jsonArray2:

[
  {"file":"hh.m4a", "version":"7"}, 
  {"file":"sh.m4a", "version":"7"}
]

Then, I want to merge these arrays like this...

jsonArrayMerged:

[
  {"file":"ay.m4a", "version":"5"}, 
  {"file":"kt.m4a", "version":"5"}, 
  {"file":"hh.m4a", "version":"7"}, 
  {"file":"sh.m4a", "version":"7"}
]

How can I do this?

can't just instantiate two JSONArray and then add the contents of one to another? — José Silva

create one new array and retrieve an object from your previous arrays and put into a newly created array — akhilesh0707

Try below code, This will give your desired result.

JSONArray jsonArray = new JSONArray();
JSONArray jsonArray1 = new JSONArray();
try {
    for (int i = 0; i < jsonArray1.length(); i++) {
        JSONObject jsonObject = jsonArray1.getJSONObject(i);
        jsonArray.put(jsonObject);
    }
} catch (JSONException e) {
    e.printStackTrace();
}

Now use jsonArray which is having all merged jsonObject
