Chapter 3, Problem 1AW
Design a class named Pet, which should have the following fields:
- name. The name field holds the name of a pet.
- animal. The animal field holds the type of animal that a pet is. Example values are “Dog”, “Cat”, and “Bird”.
- age. The age field holds the pet’s age.
The Pet class should also have the following methods:
- setName. The setName method stores a value in the name field.
- setAnimal. The setAnimal method stores a value in the animal field.
- setAge. The setAge method stores a value in the age field.
- getName. The getName method returns the value of the name field.
- getAnimal. The getAnimal method returns the value of the animal field.
- getAge. The getAge method returns the value of the age field.
-
- a. Draw a UML diagram of the class. Be sure to include notation showing each field and method’s access specification and data type. Also include notation showing any method parameters and their data types.
- b. Write the Java code for the Pet class.

- You are working with a database table that contains customer data. The table includes columns about customer location such as city, state, and country. You want to retrieve the first 3 letters of each country name. You decide to use the SUBSTR function to retrieve the first 3 letters of each country name, and use the AS command to store the result in a new column called new_country. You write the SQL query below. Add a statement to your SQL query that will retrieve the first 3 letters of each country name and store the result in a new column as new_country.arrow_forwardWe are considering the RSA encryption scheme.
