Bird b = new Crow(); what does b.cry() print?
Short answer. Caw, because Java uses the actual object at run time.
What must an overriding method keep?
The same name and the same parameters.
Remember
| Same name, same parameters |
| The object's version runs |
The variable is a Bird. The object is a Crow. What prints? Crow overrides cry with the same name and parameters. Java uses the real object. So it prints Caw. Same name, same parameters. The object's version runs.
