Adding more classes to a prewritten program

I am being tasked with adding 2 more classes to a prewritten program, one that does all calculations and one that prints the total bill. I understand how to add other classes but im a bit confused since the program already looks like it does the calculations inside of the main class.
Ive tried just adding in the classes but it throws errors because its missing information obviously.
public static void main(String[] args)
{
String squantity, snumber, output, line_output = "";
String [] item = new String [5];
double [] cost = new double [5];
double [] quantity = new double [5];
double [] amount = new double [5];
int number, i;
double grandtotal = 0;
String costout, amountout, grandtotalout;
DecimalFormat df2 = new DecimalFormat("$##,###.00");
for(i=0;i<=4;++i)
{
output = " Acme Grocery Store" + "\n" +
"1-Green Beans $0.35 per pound" + "\n" +
"2-Yellow Beans $0.40 per pound" + "\n" +
"3-Head Lettuce $0.79 per pound" + "\n" +
"4-Leaf Lettuce $1.98 per pound" + "\n" +
"5-Hot House Tomatoes $0.99 per pound" + "\n" +
"6-Hydro Tomatoes $3.98 per pound" + "\n" + "\n" +
"Please make your selection ";
snumber = JOptionPane.showInputDialog(null,
output, "Input Data", JOptionPane.QUESTION_MESSAGE);
number = Integer.parseInt(snumber);
squantity = JOptionPane.showInputDialog(null,
"Enter Quantity", "Input Data", JOptionPane.QUESTION_MESSAGE);
quantity[i] = Double.parseDouble(squantity);
//code for the calculation
if(number == 1)
{
cost[i] = 0.35;
item[i]="Green Beans";
}
else if(number == 2)
{
cost[i] = 0.4;
item[i]="Yellow Beans";
}
else if(number == 3)
{
cost[i] = 0.79;
item[i]="Head Lettuce";
}
else if(number ==4)
{
cost[i] = 1.98;
item[i]="Leaf Lettuce";
}
else if (number==5)
{
cost[i] = 0.99;
item[i]="Hot House Tomatoes";
}
else
{
cost[i] = 3.98;
item[i]="Hydro Tomatoes";
}
amount[i]=cost[i]*quantity[i];
costout=df2.format(cost[i]);
amountout=df2.format(amount[i]);
line_output=line_output+item[i]+" "+costout+" "+amountout+"\n";
grandtotal=grandtotal + amount[i];
}//for loop
grandtotalout=df2.format(grandtotal);
output=line_output+"\n"+ "The total grocery bill = "+grandtotalout;
JOptionPane.showMessageDialog(null, output, " ", JOptionPane.INFORMATION_MESSAGE);
System.exit(0);
}//main
We are expected to add the classes
class grocery {
}
class printbill{
}
I tried messing with the extends function but I dont think that is correct either

As a starter, your grocery class would look something like this:
final class Grocery
{
Grocery(String InputItem, double InputCost, double InputQuantity)
{
Item = InputItem;
Cost = InputCost;
Quantity = InputQuantity;
}
public final String GetItem()
{
return Item;
}
public final double GetCost()
{
return (double)InputQuantity * Cost;
}
private final String Item;
private final double Cost;
private final int Quantity;
}
The PrintBill class may go like this:
final class PrintBill
{
PrintBill(Grocery [] InputGroceries)
{
Groceries = InputGroceries;
}
public final void Print()
{
double Cost, TotalCost = 0.0;
String Line = "";
String Item;
for (int i = 0; i < Groceries.length; i++)
{
Cost = Groceries[i].GetCost();
Item = Groceries[i].GetItem();
TotalCost += Cost;
// I'll leave it up to you to print this info out.
Line = Item + " " + Cost +" "+ TotalCost +"\n";
}
JOptionPane.showMessageDialog(null, output, " ",
JOptionPane.INFORMATION_MESSAGE);
}
private final Grocery [] Groceries;
}
Your main() would then be:
public static void main(String[] args)
{
String squantity, snumber, output, line_output = "";
Grocery [] Groceries = new Grocery [4];
PrintBill TheBill;
int number;
for (int i = 0; i < Groceries.length; i++)
{
output = " Acme Grocery Store" + "\n" +
"1-Green Beans $0.35 per pound" + "\n" +
"2-Yellow Beans $0.40 per pound" + "\n" +
"3-Head Lettuce $0.79 per pound" + "\n" +
"4-Leaf Lettuce $1.98 per pound" + "\n" +
"5-Hot House Tomatoes $0.99 per pound" + "\n" +
"6-Hydro Tomatoes $3.98 per pound" + "\n" + "\n" +
"Please make your selection ";
snumber = JOptionPane.showInputDialog(null,
output, "Input Data", JOptionPane.QUESTION_MESSAGE);
number = Integer.parseInt(snumber);
squantity = JOptionPane.showInputDialog(null,
"Enter Quantity", "Input Data", JOptionPane.QUESTION_MESSAGE);
quantity = Double.parseDouble(squantity);
if(number == 1)
{
Groceries[i] = new Grocery("Green Beans", 0.35, quantity);
}
else if(number == 2)
{
Groceries[i] = new Grocery("Yellow Beans", 0.4, quantity);
}
// etc...
}
TheBill = new PrintBill(Groceries);
TheBill.Print();
}
More work is required to actually complete this but it should give you a starting point anyway.
Happy Days :-)

Using JOptionPane to print reports

Okay so now I got my code to compile and run, but the output is incorrect now. I need to be able to select an option and then for 2, and 3 have 3 additional options after selecting that option. How should I adapt my coding to do this?
Task:
List of all information
List of all surgeries for a specific doctor (prompt for the doctor)
List of all surgeries of a specific type (prompt for the surgery type)
Total amount of surgery fees paid to each Doctor
Average Fees

Use String or StringBuilder or StringBuffer to do this. But instead of String use either StringBuilder or StringBuffer. Since for String, you need some extra objects for String manipulation.
Ex:
StringBuilder sb = new StringBuilder();
sb.append("Id ").append(" Name\n");
for (int i = 0; i < 10; i++) {
sb.append(i).append(" Name"+i).append('\n');
}
JOptionPane.showMessageDialog(null, sb.toString());
Use HTML tags to produce better formatted results like <font>, <table>, etc.
Ex:
String startTag ="<font size='2' color='red'>";
String endTag = "</font>";
sb.append(startTag+"Some content"+endTag);

Using Strings with submenu's to print reports

I need some help finishing up my program. I have it set up so that it lists 6 options. Options 2 and 3 are supposed to open their own lists of 4 options. Right now when I select 2 or 3 it opens the correct options they should, but if I try and select one of their subsequent reports it just kicks me back to the main menu. My questions is that is their a way to alter my code to make this work the way I want it too, or should I use command-line and either way I could use some help with it as I'm thoroughly stumped. Any help is much appreciated.

Array values being set for everything (Java)

In my code below, I am having an issue where I add the customer name to one room, but instead it adds the customer to every room. I can't figure out what in my code the issue is. I have tried removing the procedure but that still produced the same problem.
package test;
import java.util.*;
public class test {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String choice, custName = "";
int roomNum = 1;
String[] hotel = new String[12];
String[] customer = new String[12];
hotelInitialise(hotel);
custInitialise(customer);
while ( roomNum < hotel.length-1 ) {
for (int i = 0; i < hotel.length-1; i++) {
System.out.println("This is the Hotel Menu. Please choose from the following options:\n");
System.out.println("A: " + "This will add a new entry\n");
System.out.println("V: " + "View all rooms\n");
choice = input.next().toUpperCase();
if (choice.equals("A")) {
System.out.println("Enter room number(1-10)");
roomNum =input.nextInt();
System.out.println("Enter name for room " + roomNum + " : " ) ;
custName = input.next();
addNewBooking(hotel, custName);
System.out.println(" ");
}
if (choice.equals("V")) {
seeAllRooms(hotel, custName);
}
}
}
}
// When the program loads it will assign all the values of the array as being empty
private static void hotelInitialise( String hotelRef[] ) {
for (int x = 0; x < 11; x++){
hotelRef[x] = "Room " + x + " is empty.";
}
System.out.println( "Welcome to the Summer Tropic Hotel.\n");
}
private static void custInitialise (String custRef[]) {
for (int i = 0; i < 11; i++) {
custRef[i] = ", no customer has occupied this room";
}
}
private static void addNewBooking(String hotel[], String customer) {
for (int x =1; x <11; x++) {
if (hotel[x].equals("Room " + hotel[x] + " is empty."))
System.out.println("Room " + x + " is empty.");
else {
System.out.println("Room " + x + " is occupied by "+ customer);
}
}
}
private static void seeAllRooms(String hotel[], String customer) {
for (int i = 0; i < hotel.length-1; i++) {
int j=0;
String custName = customer;
hotel[j]= custName;
if (hotel[i].equals("Room " + i + " is empty."))
System.out.println("Room " + i + " is empty.");
else {
System.out.println("Room " + i + " is occupied by "+ hotel[j] + ".");
}
}
}
}

In addNewBooking method you have this line:
if (hotel[x].equals("Room " + hotel[x] + " is empty."))
However hotel[x] has a value of "Room x is empty" e.g. hotel[1] is "Room 1 is empty" So the final check is becoming "hotel[x].equals(Room Room x is empty is empty.)" which is never equals to your hotel[x]
You have to change your code to
if (hotel[x].equals("Room " + x + " is empty."))
//do something there like add the booking

And my driver class:
import java.util.Scanner;
import static java.lang.System.*;
public class Driver
{
public static void main(String[] args)
{
Scanner kb = new Scanner(in);
Setup[] customer = new Setup[5];
for(int i = 0; i<6; i++)
customer[i] = new Setup(custName, cPhone, custAddress);
Setup[] room = new Setup[5];
for(int i = 0; i<6; i++)
room[i] = new Setup(roomtype, roomPrice, roomNumber);
room[1].unoccupied();
}
}
Im trying to make 5 customer objects with custName, custAddress, and cPhone as parameters, and 5 room objects with roomPrice, roomtype, and roomNumber as parameters. I tried creating the objects with arrays, but I have no idea what I'm doing, as my teacher hasn't helped me at all this year. My driver class keeps returning the error "cannot find symbol" for the parameters in the customer and room objects. Any help to fix this code so that the objects hold the parameters is appreciated.

I think you need to reconsider your abstraction. These was a quick revamp to use a more OO approach. You can extend this idea by separating rooms from customer. You should have a hotel object be a collection of Rooms and customers.
import java.util.LinkedList;
public class Hotel{
LinkedList<Customer> customers;
public void addCustomer(Customer c){
customers.add(c);
}
public void removeCustomer(int roomNumber){
boolean flag = true;
for(int i = 0; i < customers.size() && flag; ++i){
if(customers.get(i).getRoomNumber() == roomNumber)
customers.remove(i);
flag = false;
}
}
public String toString(){
String s = "";
for(Customer c : customers)
s += c.toString() + "\n";
return s;
}
}
class Customer {
private String roomType;
private String address;
private String name;
private String phone;
private String price;
private int roomNumber;
public Customer(String rmTp, String addrss, String nm, String phn, String prc, int rmNm){
roomType = rmTp;
address = addrss;
name = nm;
phone = phn;
price = prc;
roomNumber = rmNm;
}
public int getRoomNumber(){ return roomNumber; }
public String toString(){
String receipt = "";
receipt += "Customer Name: " + name ;
receipt += "Address: " + address ;
receipt += "Phone number: " + phone ;
receipt += "Thanks for making your room reservation for Geek Speak with the Orozco Hotel!" ;
receipt += "We have you booked in room number " + roomNumber + ", which is a " + roomType + "." ;
receipt += "Your charges for the convention will be $" + price + "." ;
receipt += "We hope you enjoy your stay with us and the convention.";
receipt += "The Orozco Hotel Staff";
return receipt;
}
}
