Although the MyZoo and Animal classes are similar to the classes in the original Zoo project, there are some important differences. For example, the Animal objects in the zoo are stored in a TreeMap rather than an ArrayList. Animals are added to the TreeMap using the put() method which requires a unique key value to be specified (similar to the HashMap discussed in Chapter 6). You can examine the documentation for TreeMap if you wish, but no detailed knowledge of this class is required for this project. Another difference is that the MyZoo class has a three letter identifier, provided to the constructor, and a method allocateId() for creating unique identifiers for animals…arrow_forward
