Part 1: Implement a superclass Employee that has the following fields and methods. Fields:
String firstName String lastName int employeeID double salary Methods: Constructor():
initialize balance field to null and zero. Setters and getters for firstName, lastName, and
employeeID EmployeeSummary() – prints all account attributes Part 2: Implement a Manager
class that inherits from the Employee class. Has a department attribute Methods:
EmployeeSummary() – prints all superclass and subclass attributes Ensure that your program has
the two required classes and a test class. Submit screenshots of your program’s execution and
output. Include all appropriate source code in a zip file.
