P.s: please besides the code, also include a screenshot of the code, and the output to confirm the code doesn't get edited out and the output satisfies the problem!!

Purpose: practice extending classes and overriding a method in a subclass. This example has a sub sub class See the following files: * EmployeeTester.java * Employee.java Manager.java (has todo) * Executive.java (has todo) Approximate total lines of code required: 6
