Question

I have this java program that I need to add an abstract method and polymorphism to it :

import java.util.Scanner;

//class and encapsulation
class BookTheTicket {

private String movieName;
private String theatreName;

private int ticketCost;

void myAllmovies() {

System.out.println("-------Listing the movies:------");
System.out.println(" 1.DDLJ ------------ $40 \n 2.kkr---------$.50 \n 3.game-movie --------$60 \n 4.fun movie ----- $.70 ");


}

}
// inheritence
class theater extends BookTheTicket{
private int numOfTickets;
void theater() {
System.out.println("*******Listing the theatre:******* \n 1.coco cola tld \n 2.koi gandhi kr");
int k;
int an;
Scanner sc = new Scanner(System.in);
int n = sc.nextInt();
if (n == 1) {
System.out.println("*******coco cola tld theater*******");
System.out.println("*******choose a movie name*******");
System.out.println("------Listing the movie:------\n 1.DDLJ \n 2.kkr ");
int monum = sc.nextInt();
if (monum == 1) {
System.out.println("DDLJ new movie @ coco cola tld theater");
System.out.println("Enter how many ticket to be booked:---");
int r = sc.nextInt();
int left= numOfTickets-r;
int amount=40*r;
System.out.println("press 1 to continue booking ticket----");
int h = sc.nextInt();
System.out.println("\n\n\n");
if (h == 1) {
System.out.println("******************************************************");
System.out.println("theater ------------------- coco cola tld theater");
System.out.println("movie --------------------- DDLJ");
System.out.println("cost ---------------------- $"+amount);
System.out.println("******************************************************");
}

}
if (monum == 2) {
System.out.println("kkr @ coco cola tld theater");
System.out.println("Enter how many ticket to be booked:---");
int r = sc.nextInt();
int left= numOfTickets-r;
int amount=50*r;
System.out.println("press 1 to continue booking ticket----");

int h = sc.nextInt();
System.out.println("\n\n\n");
if (h == 1) {
System.out.println("******************************************************");
System.out.println("theater ------------------- coco cola tld");
System.out.println("movie --------------------- kkr");

}

}
if (n == 2) {

System.out.println("*******choose a movie name*******");
System.out.println("------Listing the movie:------\n 1.DDLJ \n 2.kkr ");

int monum = sc.nextInt();
if (monum == 1) {
System.out.println("game-movie @ koi gandhi kr theater");
System.out.println("Enter how many ticket to be booked:---");

int r = sc.nextInt();
int left= numOfTickets-r;
int amount=60*r;
System.out.println("press 1 to continue booking ticket----");

int h = sc.nextInt();
System.out.println("\n\n\n");
if (h == 1) {
System.out.println("******************************************************");
System.out.println("theater ------------------- koi gandhi kr");
System.out.println("movie --------------------- game-movie");
System.out.println("cost ---------------------- Rs."+amount);
System.out.println("******************************************************");
}

}
if (monum== 2) {
System.out.println("fun movie @ koi gandhi kr theater");
System.out.println("Enter how many ticket to be booked:---");

int r = sc.nextInt();

System.out.println("movie --------------------- fun movie");
System.out.println("cost ---------------------- Rs."+amount);
System.out.println("******************************************************");
}

}
}

}
}

public class Main {

public static void main(String[] args) {
BookTheTicket ob1 = new BookTheTicket();

BookTheTicket [] moviename = new BookTheTicket[2];
moviename[0] = ob1;
theater ob2 = new theater();
moviename[1] = ob2;

System.out.println("@@@@@@@@@@ hello @@@@@@@@@@@@@ customer @@@@@@@@@@@@@@@@@@@@@@@@@@@@@\n");
System.out.println("---------1.list of movies and their prices--------- \n-------2.acces and book tickets through theaters---");

System.out.println("\n@@@@@@@@@@ thanks @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@");
Scanner d = new Scanner(System.in);
int h = d.nextInt();
switch (h) {
case 1: {
ob1.myAllmovies();
break;
}
case 2: {

ob2.theater();
}
}

}

}

for my final project I'm supposed to make a java program that must have:
oop objects and classes
abstract class
encapsulation
inheritance
polymorphism

and I have this code so far which I think it is missing an abstract class and polymorphism

Answer 1

//i did modifications in the above code

abstract class BookTheTicket {//abstract class

private String movieName;
private String theatreName;

private int ticketCost;

abstract void viewAvailablerefreshments();//abstract method

void myAllmovies() {

System.out.println("-------Listing the movies:------");
System.out.println(" 1.DDLJ ------------ $40 \n 2.kkr---------$.50 \n 3.game-movie --------$60 \n 4.fun movie ----- $.70 ");
