In a separate testing program, create ONE array that will hold 3 ProductionWorker objects and 3 ShiftSupervisor objects (think about what data type this array will have to be defined with). Create a menu to let users select the following functionality:
Display all worker names and job titles (i.e. Kevin --- Foreman)
Display all workers who receive an annual bonus
Display all workers on the night shift
Display all worker information
Do not use import java.util.ArrayList
