1z0-819 Exam - Question 85

Question

Given:Which is true? (Choose four. ).

Examice · Accepted Answer

The code provided has the following structure: an interface `Pastry` with a `getIngredients` method, an abstract class `Cookie` implementing `Pastry`, and two concrete classes `ChocolateCookie` and `CoconutChocolateCookie`. The code complies properly because: 1) Lines 6 and 9 are correct. The `ChocolateCookie` class can implement the `Pastry` interface indirectly through the `Cookie` abstract class. 2) The `CoconutChocolateCookie` class can override the `getIngredients` method with an additional parameter `int x`. This is method overloading, not overriding, which is allowed. Thus, the correct answer is that the compilation succeeds, as indicated in option G, and the error claimed in line 6 from option E, is indeed valid, as one cannot implement another class, they must extend it.

all classes are decalred with the default modifier so all of them are visible only within its own package

for oveloaded methods access modifier can be changed
