What's wrong with my answer for this question?

Fragment NewsFragment = new Fragment(); FragmentManager fragmentManager = getFragmentManager(); FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction(); fragmentTransaction.add(R.id.placeholder, NewsFragment); fragmentTransaction.commit();

NewsFragment.java 
public class NewsFragment extends Fragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
              View view = inflater.inflate(R.layout.fragment_news, container, false);
        return view;
    }
}
MainActivity.java 
public class MainActivity extends AppCompatActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


      Fragment NewsFragment = new Fragment();
      FragmentManager fragmentManager = getFragmentManager();
      FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
            fragmentTransaction.add(R.id.placeholder, NewsFragment); 
      fragmentTransaction.commit();


    }
