Sample output

Lab 03 SuperClasses and SubClasses General Information Use an existing class (Pet) as a superclass; code two subclasses (Mamma1 and Reptile) to the superclass. Use basic polymorphic processing to test the class hierarchy. Instructions Use your (complete & correct) copy of Pet from Lab 02 as a starting point for this lab. Create two new subclasses, Mammal and Reptile, based on the superclass Pet, according to the UML Class Diagrams provided. Zip the two (2) source files (Mammal.java, and Reptile.java) into folder named Lab03 Submission. Include source code for Mammal and Reptile only in the zipped folder. DO NOT include the test harness, Pet.java, edit/backup versions of the source code, or compiled code. Submit only the zipped folder Lab03 Submission as an attachment to this assignment. Submission in any format other than a zipped folder will result in a grade of zero (0). Provided to You The following resources are provided: These instructions The UML Class Diagrams for the Pet hierarchy, including Mammal and Reptile classe:s . Source code for a test harness to use in testing your code . Sample output from the provided test harness Requirements Code the Mammal and Reptile subclasses per the provided UML Follow Basic Coding Standards, as published on Blackboard In the subclass tostring methods, DO NOT "hard code" the class name! Retrieve the class name in each instance from the system. (Hint: Remember, an object always knows its class.) Pet Attributes private name: String private species: String private parent: String private birthday: String Pet's name Pet's species (NOTE: not breed) Pet's parent (owner) name Pet's birthday in yyyy/mm/dd format: 2017/02/28 Operations public Pet ): Pet public > Pet (name: String, Default or null constructor; returns a reference to a fully functional Pet object Constructor accepting four (4) parameters, all of type String. Returns areference to a fully formed and functional Pet object species: String, parent: String birthday: String): Pet public toString):Strin Returns a formatted String containing a verbose description of the Pet object NOTE: Set and get methods are assumed; further, standard naming is assumed for these methods.
