Exam 1z0-808 topic 1 question 6 discussion

C, D Cannot reduce the visibility of the inherited method from an abstract class. In this case, can't change resolve from protected > default But you can change it to protected > protected protected > public

'revolve()' in 'Earth' clashes with 'revolve()' in 'Planet'; attempting to assign weaker access privileges ('package-private'); was 'protected'. Change revolve() public or protected.

Answer: C or D. Compilation Error: Cannot reduce the visibility of the inherited method from Parent. Solution: Make Earth.revolve() from default to protected/public. The order from least to most visible is: private < 'default' < protected < public. Code: abstract class Parent { protected void revolve() {} // n1 abstract void rotate(); // n2 } class Earth extends Parent { void revolve() {} // n3 protected void rotate() {} // n4 }

Answer C, D

I see hier 3 correct answers: C,D,E! E is ciddect too, because method rotate() can bee public. I have tested it!

réponse A et E

The correct answer is C and D as the overriden method in child class should be as least as accessible as the parent class method. Thus. by making it public and protected it will be more / same accessible as parent class method.

Because for metjod overriding the method which is overriding should be as accessible as than the overridden method

Correct answers are C, D. We only have to make changes in //line n3 Either we have to keep it the same as protected or we can widen the scope to public. private< (default) < protected < public //line n4 is already correct because the scope was widen from (default) to protected.

CE. protected line 4 can be change to public. D: protected = protected
