Examine the given definitions: and the code fragment: Which statement is true about the implementation of Object-Oriented Programming concepts in the given code?
A.
Polymorphism, abstraction, and encapsulation are implemented.
B.
Only polymorphism and inheritance are implemented.
C.
Polymorphism, inheritance, and abstraction are implemented.
D.
Only inheritance and encapsulation are implemented.
The answer should be A as the encapsulation is done by .setPlayers and setting the players list as private, thus hiding the data. There is no inheritance as Game only implements, but not extends, the interface
The answer is C. We make a polymorphism when we instantiate a variable of type "playable" referencing an object of type "Game", we have erance because the "Game" class inherits the methods of the "playable" interface and we have abstraction because by default any method of an interface is abstract, public and void, so we have abstraction as well.
As said there in polyorphism but other 2 are implemented
