Question

Which of the following is not a method of the ResourceFactory class?

(a) createResource()

(b) releaseResource()

(c) shutdown()

(d) freezeResource()

I have been asked this question during an online interview.

This interesting question is from Software Architecture topic in portion Software Defined Radio Architecture of Cognitive Radio

Answer 1

Right choice is (d) freezeResource()

For explanation I would say: ResourceFactory class is used when a Resource has to be explicitly created. The createResource() interface creates an instance of the desired Resource, the releaseResource() calls the releaseObject() interface, and shutdown() terminates the ResourceFactory.
