26. Two objects, objectA and objectB, are objects in the class Listing. The object objectA is copied to objectB. How many objects exist after the copy, if the copy is performed as:

(a) a deep copy?

(b) a shallow copy?

27. Of the two types of copies discussed in the previous exercise, which one produces a clone (an exact duplicate of an existing object)?

28. Give the signature of a method named deepCopy, that clones an object in the class Listing sent to it as a parameter and returns a reference to the clone.

29. Give the Java invocation to clone the object objectA (using the method discussed in the previous exercise) and store a reference to the clone in the variable: newListing.
