Question
Choose the correct statements among the following:An abstract method does not have implementationAn abstract method can take either static or virtual modifiersAn abstract method can be declared only in abstract classAll of the mentioned
Solution 1
The correct statements among the following are:
- An abstract method does not have implementation.
- An abstract method can be declared only in an abstract class.
The incorrect statement is: An abstract method can take either static or virtual modifiers. This is not true because in most programming languages, an abstract method cannot be static or virtual. It is implicitly virtual and it cannot have any implementation, so it cannot be static.
Solution 2
The correct statements among the following are:
- An abstract method does not have implementation.
- An abstract method can be declared only in an abstract class.
The incorrect statement is: An abstract method can take either static or virtual modifiers. This is because in most programming languages like Java and C#, an abstract method cannot be static or virtual. It is implicitly virtual and it cannot be static because it is associated with an instance of a class, not the class itself.
