NOTE: ENTER YOUR UDIL ID ON THE PACKAGE (edu.iltu.itk275.assignment4.yourUDIL) All of the java classes should be placed in a package named edu.iltu.itk275.assignment8.. The class should be submitted as an attachment to this assignment. They may be submitted individually or placed into a single archive (.zip) file. In the previous programming assignment, the Alien class was rewritten to use inheritance. The rewritten Alien class should be made abstract because there will never be a need to create an instance of it, only its derived classes. Change this to an abstract class and also make the getDamage method an abstract method. Test the class from your main method to ensure that it still operates as expected.
