Multiple fragments with same method

I have 5 fragments, where each fragment class has the exact same method:

public class FirstFragment extends Fragment {
    // other methods

    public void clear() {
        data.clear();
        adapter.notifyDataSetChanged();
    }
}

The second fragment:

public class SecondFragment extends Fragment {
    // other methods

    public void clear() {
        data.clear();
        adapter.notifyDataSetChanged();
    }
}

And so on...

How can I organize my code better so that I don't have to copy and paste this method into each of my 5 fragments (i.e. make one method, call the same method in each fragment).

you need to use the concept of Inheritance, put all the common variables and methods in a BaseFragment and extend others from it. 

public class BaseFragment extends Fragment {
public Data data;
public Adapter adapter;
        public void clear() {
            data.clear();
            adapter.notifyDataSetChanged();
        }
    }

First:

public class FirstFragment extends BaseFragment {
    // other methods
}

Second:

public class SecondFragment extends BaseFragment {
    // other methods
}
