SHOW ALL YOUR WORK. REMEMBER THAT PROGRAM SEGMENTS ARE TO BE WRITTEN IN JAVA. Assume that the classes listed in the Java Quick Reference have been imported where appropriate.
Unless otherwise noted in the question, assume that parameters in method calls are not null and that methods are called only when their preconditions are satisfied.
In writing solutions for each question, you may use any of the accessible methods that are listed in classes defined in that question. Writing significant amounts of code that can be replaced by a call to one of these methods will not receive full credit.

A set of classes using inheritance is used to represent animals observed at a wildlife sanctuary. A portion of the class hierarchy is shown in the following diagram.
The figure presents a diagram of a class hierarchy with three levels. The highest level has one class labeled Animal. The middle level has two classes labeled Carnivore and Herbivore. The lowest level has one class labeled Elephant. Three arrows are drawn: one from Elephant to Herbivore, one from Herbivore to Animal, and one from Carnivore to Animal.

All Animal objects have the following attributes.

A String variable indicating whether the animal is a carnivore or a herbivore
A String variable representing the animal species (e. g., lion, giraffe, zebra)
A String variable representing the name of the individual animal (e. g., Lisa, Gary, Percy)

The Animal class also contains a toString method that indicates the state of an animal.

The following table shows the intended behavior of the Animal class.
Statement Result
Animal lisa = new Animal("carnivore", "lion", "Lisa"); A new Animal object is created.
lisa. toString(); The string "Lisa the lion is a carnivore" is returned.

(a) Write the complete Animal class. Your implementation must meet all specifications and conform to the behavior shown in the table.
