Java OCA OCP Practice Question 983

Question

Suppose you want to write a class that offers static methods to compute hyperbolic trigonometric functions.

You decide to subclass java.lang.Math and provide the new functionality as a set of static methods.

Which one statement is true about this strategy?

  • A. The strategy works.
  • B. The strategy works, provided the new methods are public.
  • C. The strategy works, provided the new methods are not private.
  • D. The strategy fails because you cannot subclass java.lang.Math.
  • E. The strategy fails because you cannot add static methods to a subclass. 


D.

Note

The java.lang.Math class is final, so it cannot be subclassed.
