Need help with a simple java program. Will give upvote and comment for help!

Program Implementation Requirements Use the stack concept to create a post-fix calculator. It will be using a test-harness to run the program. Please make sure it can be run by the test harness.

LinkedList/Queue - Implementation: New concert tickets are available. You have to enter the names of the people in order to form a line. However, you will later find out that a few people are not eligible to buy tickets because they represent scalpers instead of actual concert goers. You will have to remove those people from the line. A special raffle will be done and the result of the raffle will insert a person to the front of the line. You will have to issue tickets to the first 10 people in line, but there are 15 people total in line. The others will have to put into a waitlist queue for the next available ticket.

Program Implementation:

Concepts: Stack Post-Fix calculator

Use the Linked List (Original Line) and a Queue (waitlist) concept to create this program. The class name will be ConcertTickets. You will have the following methods: insertIntoLine(Person p), removeFromLine(Person p), addToWaitList(Person p), assignedTicket().

Test harness used:

import java.util.ArrayList; public class ConcertTicketsTest { public static void main(String[] args) { ArrayList listOfPeople = new ArrayList(); listOfPeople.add("Monica"); listOfPeople.add("Chandler"); listOfPeople.add("Rachel"); listOfPeople.add("Phobe"); listOfPeople.add("Joey"); listOfPeople.add("Ross"); listOfPeople.add("John"); listOfPeople.add("Daenerys"); listOfPeople.add("Arya"); listOfPeople.add("Sansa"); listOfPeople.add("Rob"); listOfPeople.add("Ned"); ConcertTickets concertTickets = new ConcertTickets(listOfPeople); concertTickets.removeFromLine("Ned"); concertTickets.removeFromLine("Ross"); concertTickets.insertInFront("Cersei"); System.out.println(concertTickets.printWaitlist()); System.out.println(concertTickets.listOfTicketHolders()); } }
