Android: How to get boolean result from AsyncTask?

Issue

I want to check Internet connectivity in my App. I found a code but I don't know how to use since I'm really a beginner.

My code :

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
            //I want something like this.
            if(InternetCheck==true){
                Toast("You are connected to internet")
            }
            else{
            Toast("Connection Failed")
            }

    }

 static class InternetCheck extends AsyncTask<Void,Void,Boolean> {

        private Consumer mConsumer;
        public  interface Consumer { void accept(Boolean internet); }

        public  InternetCheck(Consumer consumer) { mConsumer = consumer; execute(); }

        @Override protected Boolean doInBackground(Void... voids) { try {
            Socket sock = new Socket();
            sock.connect(new InetSocketAddress("8.8.8.8", 53), 1500);
            sock.close();
            return true;
        } catch (IOException e) { return false; } }

        @Override protected void onPostExecute(Boolean internet) { mConsumer.accept(internet); }
    }

But I don't know how to get a boolean result from AsyncTask. Please teach me.

Solution

new InternetCheck(new InternetCheck.Consumer() {
    @Override
    public void accept(Boolean connected) {
        if (connected) {
            Log.d("TAG", "Internet is connected");
        } else {
            Log.d("TAG", "Internet is not connected");
        }     
    }
}).execute();
