The Animal abstract class has the following data & methods: o A private String variable to hold the name o Mutator & accessor for the name o Three walk, sleep, and drink methods that print that the animal can walk, sleep, and drink respectively o Two abstract methods eat and speak. These methods must be implemented by classes that are derived from this abstract class, since they are different for each of the animals.

Notes: o You can add any other animal that you like. o Expand the structure to include other mammals. What data members and/or methods would you add to the abstract class?
