In our TeaViewModel class, that extends ViewModel, we have such method:
public LiveData getTea() { return mTea; }
An observer in our Activity (type of mViewModel variable in example is TeaViewModel) is set in this way:
mViewModel.getTea().observe(this, this::displayTea);
What will be a correct displayTea method definition?
