Why did you make 2 logs if you're just going to remove one of them?

I don't see the reason why you did it, could you please explain?

if your talking about why he made two Log.v, That's because he wanted to see a response from the if part of the statement, and another from the else part of the statement, he removed one because of the principle DRY "don't repeat yourself"

But why is he putting the log over the if statement. As far as I understood it becomes if: .... else: alert user about error ´´´ java public void onResponse(okhttp3.Call call, Response response) throws IOException {try {

            Log.v(TAG, response.body().string());
            if (response.isSuccessful()){

            else { alertUserAboutError();

        } catch (IOException e) {

            Log.e(TAG, "Exception Caught", e);
