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

Answer A and B

Actually, I need to revise my previous answer. The correct combination is C and E. Because: Earth's revolve() (line n3) has default access but inherits from protected access in Planet - it needs to be made at least protected (option D) or public (option C) Earth's rotate() (line n4) is implementing an abstract method with default access - it needs to be made public (option E) as it can't be more restrictive than the parent's access level Therefore my final answer is C and E - Make line n3 public and line n4 public.

We need TWO modifications that would allow compilation. The valid combinations are: - D and E would work together - Making Earth's revolve() protected to match parent, and making rotate() public to be accessible. - C and E would work together - Making both Earth methods public would satisfy all access requirements. Therefore, the two modifications that would enable the code to compile are: D. Make the method at line n3 protected AND E. Make the method at line n4 public

default has more visibility than protected

'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
