Which code fragment is illegal?


Correct Answer: D
The abstract keyword cannot be used to declare an int variable.
The abstract keyword is used to declare a class or method to be abstract[3]. An abstract method has no implementation; all classes containing abstract methods must themselves be abstract, although not all abstract classes have abstract methods.
