Project Description: Design a generic ADT Priority Queue which is implemented with a generic ADT Heap of Employee and its comparators. Assume that each employee object contains two unique values: .name: a full name in a format as in "John Smith". pay rate: a numeric value indicating the annual income of an employee. Assume we store a list of employees using an ADT priority queue according to their names or their pay rates. Therefore, we need to create two comparators. .name comparator, compares/sorts employees by their names. pay rate comparator: compares/sorts employees by their pay rates. To organize employees in a priority queue, first create an empty priority queue with a reference to a comparator passed into the constructor as the ordering for the queue (more accurately for the heap that is used to implement the queue). And then, insert the employees into the queue according to their priority defined in the comparator. name pay rate name pay rate James Butt 30000 Leota Dilliard 10000 Lenna Paprock 500 minna amigon 3000 Art Venere 12000.00 kris marrier 30030 These data can be used in the testing phase for this project. Save them into a plain text file. If the comparator compares employee names, the name in the root of a heap is greater than the names of its children. If the comparator compares employee pay rates, the pay rate in the root of a heap is greater than the pay rates of its children. To use Employee to test this project, we need to design three classes. Employee A name comparator for employee, a class implementing the interface java.util.Comparator. A pay rate comparator for employee, a class implementing the interface java.util.Comparator. A generic ADT Heap should contain the following operations. When designing a method, you should consider all possible exceptions. Insert: inserts an item into a heap. "delete: retrieves and removes the item in the root of a heap. heapify: rebuild a heap if the root is not a leaf and the root's priority/key is less than the larger of the keys of the root's children. isEmpty: determines if a heap is empty. sort: sorts the items in a heap using the Heap Sort algorithm. more When implementing the generic ADT Heap, two attributes should be included. an array list must be used as data structure. +It is not allowed to use any other Java ADTs/JFC Collection types in the java library. A reference to a comparator specifying the ordering used for organizing a list of objects in a heap. A generic ADT Priority Queue contains a reference to a generic ADT Heap and execute most of the following operationsin the heap. When designing a method, you should consider all possible exceptions. insert: inserts an item into a heap. This method should invoke insertof the heap. delete: retrieves and removes the item in the root of a heap. This method should invoke delete of the heap. isEmpty: determines if the heap is empty. This method should invoke isEmpty of the heap. sort: sorts the items in the heap using the Heap Sort algorithm. This method should invoke sort of the heap. more Test: To test the entire project, write a driver with a helper class that creates an empty priority queue, inserts a list of employees, sorts the queue, deletes from the queue, and displays the queue. The following provides you with some ideas. Create a helper class. In the helper class, at minimum three static methods should be created. public class Helper public static void start() { Create an empty priority queue and save its reference. Pass the reference to createmethod. Pass the reference to displaymethod. Sort the queue. Display the queue again. Delete from the queue. Display the queue again. public static returnTypeOrvoid create a reference to a queue) { Make employee objects from the testing data in a file. Insert the employee objects into the queue. } public static returnTypeOrVoid display(a reference to a queue) { Displays objects in the queue. } ) Create a driver program. In main of the driver program, call method start to start the entire testing process. public class Driver { public static void main(String[] args) { Helper.start(); } Make sure that all methods are tested. You may add ore program statements in the method start. Notice that the driver and its helper class are for testing purpose only. They should not be included in the design diagram. But you need to submit their source codes. Project Description: Design a generic ADT Priority Queue which is implemented with a generic ADT Heap of Employee and its comparators.
