Consider the following implementation of a $1$D vector class:Is this class immutable? Answer yes$/$no$,$ and justify.No $-$ although the member variable is set to final, the constructor does not make a deep copy.Yes $-$ the member variable is set to final and that is sufficient.Yes $-$ the member variable is set to final and the constructor makes a deep copy.No $-$ the constructor always throws an exception before it is able to copy the data.Yes $-$ the constructor validates that there is no outside refeference to the data and throws an exception if there is$.$No $-$ this would not even compile since there is an assignment to a final variable in the constructor.
