Question

I have a small function in java that does a HTTP POST, and returns a JSON Object. This function return the JSON Object.

public JSONObject send_data(ArrayList<NameValuePair> params){
    JSONObject response;
    try {
        response = new JSONObject(CustomHttpClient.executeHttpPost(URL, params).toString());
        return response;
    } catch(Exception e) {
        // do smthng
    }
}

This shows me an error that the function must return a JSONObject. how do i make it work? I cant send a JSONObject when there is an error, can I? It would be useless to send a blank jsonobject

Answer 1

There’s a path through the function that doesn’t return anything; the compiler doesn’t like that.

You can change this to

catch(Exception e) {
    // do smthng
    return null; <-- added line
}
or put the return null (or some reasonable default value) after the exception block.
