Hello, i have answered correctly this but i have a question maybe is not into the concept...
What exactly do you mean by "If you later decide to change your DAO implementation, you would have to recompile School as well."
If you want to implement another DAO implementation class
or
If this DAO implementation class is changed(a method which School uses is deleted) you have to recompile them both?
Thanks,
Jim
