Which of the following can fill in the blank in this code to make it compile?
- A. public
- B. It will not compile with any as interfaces cannot have non abstract methods.
- C. abstract
- D. default
- E. It will compile without filling the blank.
Answer: D
Explanation:
From Java SE 8, we can use static and/or default methods in interfaces, but they should be non abstract methods. SO in this case using default in blank is completely legal. Hence option C is correct. Option A is incorrect as given method is not abstract, so can't use abstract there. Options B and E are incorrect as we can't have non abstract method interface if they are not default or static. https;//docs.oraclexom/javase/tutorial/java/Iandl/defaultmethods.html
