5/5 – (1 vote)

Suppose that you are required to write an application to model interns and supervisors in a company.1- Define an abstract superclass called Staff to store two properties as:String name;String address;[4 points] Provide (only one) constructor which sets the name and address properties.[6 points] Provide getters & setters and toString() methods for the class Staff.2- Define:[2 points] Two subclasses of Staff, one named Intern and one Supervisor.[3 points] Both classes, Intern and Supervisor must implement the interface StaffInfo, provided below.3- Requirements for the class Intern:• should maintain a list of tasks taken and the respective hours for each task.• an intern cannot have more than 10 tasks• should also provide a method to add a task with hours• print all tasks taken with task description and hours• calculate the average hours of the tasks assigned[5 points] Intern(…) constructor calling the parent constructor[5 points] private instance variables: numTasks, taskList[], hourList[], MaxNumTasks=10[5 points] toString() method to describe itself. Add the string “Intern: ” to the beginning.[5 points] addTaskHours(task, hours) adds a task and its hours. Validate that task description is not null and hours are greater than zero[5 points] // printHours() prints all Tasks taken and their hour[5 points] // getAverageHour() computes the average hour4- Requirements for the class Supervisor:• should maintain a list of tasks they currently supervise• be able to add or remove a task supervised• assume that a supervisor cannot supervise more than 5 tasks[5 points] private instance variables: numTasks, taskList[], MaxNumTasks=5[5 points] Supervisor (…) constructor calling the parent constructor[5 points] toString() method to describe itself. Add the string “Superviser: ” to the beginning.[5 points] addTask(task) adds a task to task list. Returns false if task already in the list.[5 points] removeTask (task) removes a task from task list. Returns false if task not found.Note: Your program solution may only be uploaded in .jar format. No other format will be graded.Interface to be implemented by the Intern & the Supervisor class as described in item 2 above./*************************************************** StaffInfo interface declaration.**************************************************/public interface StaffInfo {// Returns (String “Supervisor” or “Intern”), name + address of the staffString getStaffInfo();}
