Task 1: Implement Abstract Class KeanPerson using UML (10 points) • Four data fields • Two constructors (1 default and 1 constructor with all fields) • Getters and setters for firstName and lastName • Getters for keanEmail and keanld • Override toString(): create your toString to match the example output • Abstract method getParkingRate() Task 2: Implement Public Class KeanAlumni extends KeanPerson (10 points) Note: • KeanAlumni has two new properties: a yearOfGraduation (for example, 2020) and a employmentStatus (for example, full-time employee). • Two constructors (1 default and 1 constructor with all fields) • Also, please implement the abstract method getParkingRate() (for example, return 9.99). • In KeanAlumni's toString method, please not only show the two variables in KeanAlumni, but also use the super keyword to show the superclass's variables. • Getter and setter for yearOfGraduation • Don't need to create a getter and setter for employmentStatus Task 3: Test Class KeanAlumni (5 points) • Create a main method in KeanAlumni • Create one KeanAlumni object with parameters of your choice (create the actual data yourself) in the main method. • Display/print these objects to the Console. Example output: keanId: 10000, keanEmail: jt@kean,edu, firstName: John, lastName: Tim, yearOfGraduation: 2020, employmentStatus: full-time Submit all the source code you created for this assignment, including the parent's code and child's code.
