For this coding challenge you'll be asked to create three classes. In this practice challenge, you'll create classes Employee, PartTimeEmp and FullTimeEmp. During the challenge, you'll have to put the three .java files in a zip file. On Linux, the following command will do so: zip -r submit.zip Employee.java PartTimeEmp.java FullTimeEmp.java (In this case the zip file is called submit.zip and is ready to be uploaded to WebCAT. You can call the zip file anything you want but keep the .zip extension.) A practice WebCAT folder is available to allow you to practice this before your actual coding challenge. The focus of this challenge is on inheritance. Make sure to override as required and invoke parent constructors as appropriate. You do not have to validate arguments to methods for this challenge The following class diagram shows the three classes you are to create
