Exception is not not thrown

I try to develop under Android. Now I try to use network.

I have the "manager class"

private String makeQuery(String string){
    Log.d("makeQuery", "in");
    try{
        NetTask a = new NetTask(server_url);
    }catch(IOException e){
        Log.d("makeQuery", "exception");
    }
    Log.d("makeQuery", "out");
    return "string";
}

It have the method for queries to my own API server over HTTP. It uses NetTask object, NetTask inheritance AsyncTask

public class NetTask extends AsyncTask<String, Void, Void> {

HttpURLConnection connection;

public NetTask(URL server) throws IOException{
    Log.d("NetTask", "Create");
    connection = (HttpURLConnection)server.openConnection();
    connection.setReadTimeout(10000);
    connection.setConnectTimeout(15000);
    connection.setRequestMethod("GET");
    connection.setDoInput(true);
    connection.setDoOutput(true);
    Log.d("NetTask", "Connect");
    connection.connect();
    Log.d("NetTask", "Response");
    int response = connection.getResponseCode();
    Log.d("NetTask", "The response is: " + response);
}

In my case I get next logs:

[makeQuery]

[NetTask]

So, why line Log.d("makeQuery", "out"); is not reachable?

Why Log.d("makeQuery", "out"); is un reachable?

 try{
        NetTask a = new NetTask(server_url);
    }catch(IOException e){
        Log.d("makeQuery", "exception");
    }

The reason is that NetTask class throws other kind of exception.

you will change to

    }catch(Exception e){
        Log.d("makeQuery", "exception");
    }

but the good practice says catch the correct Exception, comment the exception handling and look into your LogCat for the type of Exception.
