Lab 02 Defining a Class; Objects, & instantiation General Information This lab will review defining a Class of objects, instantiating objects of that class, and calling methods of an instantiated object. Instructions Write a Java class named Pet to meet the requirements described in the UML Class Diagram attached to the assignment. This lab will adhere to the published Coding Standards. Failure to follow the standards will have a significant and negative affect on your grade for the lab. Zip your source code (and only your source code) and submit the zipped folder as an attachment to the assignment in Blackboard. DO NOT submit edit/backup versions (with the in the file type) or compiled code (.class files); submission of either will result in a grade of zero (0). Provided to You The following resources are provided: These instructions, including sample toString output The UML Class Diagram for class Pet A test harness to use in testing your Pet.java code o NOTE: Grading does not use the provided test harness. The code used for grading will verify that your submitted code follows the published Coding Standards Requirements The provided UML Class Diagram describes the requirements for the class Pet. In addition to the requirements described there, be aware of the requirements included in the Coding Standards. Specifically be aware of the following: All get and set methods must be named according to industry standards, based on the provided UML document. All get and set methods must be 'final' methods. (We will discuss this at greater length in the lecture class.) The only direct access to instance variable values is through the set and get methods; no other direct access is every permitted. Expected toString Output Your output need not be identical to that shown here, but you MUST include all instance values in the output, in the order shown. Spot, whose fur-parent is Data, is a Cat, born on 1991/01/05 Mr. Ed, whose fur-parent is Wilbur, is a Horse, born on 1961/01/04 Grading Grading rubric for this lab: Submission Pet.java submitted, compiles cleanly, is defined correctly, & functions exactly as required Pet.java submitted, compiles cleanly, is defined correctly, but some output is missing Pet.java submitted, compiles cleanly, but output is incorrect Any submission that does not match one of the above groupings. This will include any significant transgression of Coding Standards.
