What is the best way to combine (merge) 2 JSONObjects?

Question

What is the best way to combine (merge) two JSONObjects?

JSONObject o1 = {
    \"one\": \"1\",
    \"two\": \"2\",
    \"three\": \"3\"
}
JSONObject

I have your same problem: I can't find the putAll method (and it isn't listed in the official reference page).

So, I don't know if this is the best solution, but surely it works quite well:

//I assume that your two JSONObjects are o1 and o2
JSONObject mergedObj = new JSONObject();

Iterator i1 = o1.keys();
Iterator i2 = o2.keys();
String tmp_key;
while(i1.hasNext()) {
    tmp_key = (String) i1.next();
    mergedObj.put(tmp_key, o1.get(tmp_key));
}
while(i2.hasNext()) {
    tmp_key = (String) i2.next();
    mergedObj.put(tmp_key, o2.get(tmp_key));
}

Now, the merged JSONObject is stored in mergedObj
