# Quiz 4: Interfaces

• Create two interfaces; one is called File; the other is Bank. Both have a concrete method called save(String) plus another method of your choosing. Bank just prints "saved money to account number xyz" (xyz is the argument; the String account number). The File save() prints "saved fata to file xyz" (the argument is a filename String). The create a class OnlineBankAccount that implements both interfaces. The OnlineBankAccount overrides the save() method to perform the Bank version. (7/8)
