Can you kindly help me with the assignment attached below regarding java programming?
I'm using eclipse for this assignment. My task is to write a program that sells different types of tickets (e.g., student, child, adult, senior citizen) for a theater by using inheritance, abstract class and java interfaces.
I really appreciate your time and effort.
Write a program that sells different types of tickets (e.g., student, child, adult, senior citizen) for a theater. (utilize the concepts of : inheritance, abstract class and java interfaces. )
- Create an abstract class Ticket that has:
variable id: a unique identify for each ticket and has type int
variable price: price per one ticket, has type float
Constructor Ticket(int id, float price) for assigning values to 2 variables id and price
- Create 4 classes: SeniorTicket, AdultTicket, ChildTicket and StudentTicket which extends abstract class Ticket and implement constructor and toString method for each class.
- Prices: $20 for adult, $10 for senior and children and $15 for student ticket.
- Create class TheaterTicketService which implements TicketService interface ( file TicketService.java) and sellTicket method. sellTicket method should return an object that is instance of one of 4 class: SeniorTicket, AdultTicket, ChildTicket and StudentTicket depend on ticketType.
- Class TheaterTicketService should:
-Instance variable int capacity : total number of tickets
-Instance variable int soldTicket : total number of sold tickets
-Instance variable float revenue which is the total money of selling tickets; also implement a getter for this variable .
- constructor TheaterTicketService(int capacity)
For example:
TheaterTicketService tts = new TheaterTicketService(20);
Ticket adultTicket = tts.sellTicket(TicketService.Type.ADULT);
System.out.println("Sold " + adultTicket.toString());
Ticket childTicket = tts.sellTicket(TicketService.Type.CHILD);
System.out.println("Sold " + childTicket.toString());
System.out.println("Total tickets: " + tts.getCapacity() + " ;Ticket Sold: " + tts.getTicketLeft());
System.out.println("Revenue until now: " + tts.getRevenue());
should have output:
Sold Adult ticket, id: 1, price: $20.0
Sold Child ticket, id: 2, price: $10.0
Total tickets: 20 ;Ticket Sold: 18
Revenue until now: $30.0

Explanation / Answer
Abstract class ticket{
int vairableid;
float price;
int Ticket(int id, float price);{
id=123;
price=4.2;}
}
public class TheaterTicketService implements TicketService{
int capacity;
int ticketssold;
float revenue;
TheaterTicketService(int capacity) {
capacity=100;
}
int sellTicket(){
childticket a;
adultticket b;
seniorticket c;
studentticket d;
if(Tickettype="a")
return a;
or else if(tickettype="b")
return b;
else if(tickettype="c")
return c;
else return d;
}
class childticket(){
System.out.println("enter age");
Scanner in =new scanner(system.in);
if (in<10){
system.out.println("childticket ");} //similary we write other three classes student, adult , seniorcitizen ticket
}
public int getcapacity(int capacity)
{
Integer[] oapQuantityList = {0,1,2,3,4,5};
}
}
string toomanytickets()
{
System.out.println("You cannot Process more than 5 tickets at a time!"");
}
string notEnoughSeats()
{
system.out.println("There are not enough seats remaining to process the number of tickets selected", "Ticket Quantity Error");
}
public int getrevenue(int){
}
public static void main (String[] args)
{
TheaterTicketService tts = new TheaterTicketService(20);
Ticket adultTicket = tts.sellTicket(TicketService.Type.ADULT);
System.out.println("Sold " + adultTicket.toString());
Ticket childTicket = tts.sellTicket(TicketService.Type.CHILD);
System.out.println("Sold " + childTicket.toString());
System.out.println("Total tickets: " + tts.getCapacity() + " ;Ticket Sold: " + tts.getTicketLeft());
System.out.println("Revenue until now: " + tts.getRevenue());
}
Integer[] adultQuantityList = {0,1,2,3,4,5};Related Questions
