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);

At the moment my code is only giving me the first matching result. The user inputs their desired room price and at the moment it will only display the first match. In the case the user inputs '60' to the console it should display 3 results. I imagine i'll need another forloop and if statement after it prints to the console but not sure how to execute
public static void secondMain() {
BufferedReader reader;
var lines = new ArrayList<String>();
var rooms = new ArrayList<Room>();
Room selectedRoom = null;
try {
reader = new BufferedReader(new FileReader("rooms.txt"));
String line = reader.readLine();
lines.add(line);
while (line != null) {
line = reader.readLine();
lines.add(line);
}
reader.close();
for (int i = 0; i < lines.size() - 1; i++) {
String[] words = lines.get(i).split(" ");
var room = new Room();
room.roomNum = Integer.parseInt(words[0]);
room.roomType = (words[1]);
room.roomPrice = Double.parseDouble(words[2]);
room.hasBalcony = Boolean.parseBoolean(words[3]);
room.hasLounge = Boolean.parseBoolean(words[4]);
room.eMail = (words[5]);
rooms.add(room);
}
var searchRoomPrice = input.nextDouble();
for (int i = 0; i < rooms.size(); i++) {
if (rooms.get(i).roomPrice == searchRoomPrice) {
selectedRoom = rooms.get(i);
break;
}
}
System.out.println("Room Number: " + selectedRoom.roomNum);
System.out.println("Room Type: " + selectedRoom.roomType);
System.out.println("Room Price: " + selectedRoom.roomPrice);
System.out.println("Balcony: " + selectedRoom.hasBalcony);
System.out.println("Lounge: " + selectedRoom.hasLounge);
System.out.println("Email: " + selectedRoom.eMail);
System.out.println("-------------------");
} catch (Exception e) {
e.printStackTrace();
}
}
Any other information needed feel free to ask
If you only want to print the information move the print commands inside the loop and remove the break i.e.
for(int i = 0; i < rooms.size(); i++){
if(rooms.get(i).roomPrice == searchRoomPrice){
selectedRoom = rooms.get(i);
System.out.println("Room Number: " + selectedRoom.roomNum);
System.out.println("Room Type: " + selectedRoom.roomType);
System.out.println("Room Price: " + selectedRoom.roomPrice);
System.out.println("Balcony: " + selectedRoom.hasBalcony);
System.out.println("Lounge: " + selectedRoom.hasLounge);
System.out.println("Email: " + selectedRoom.eMail);
System.out.println("-------------------");
}
}
You could also save all the objects in a list with the first loop and then in a second loop iterate over the list and print the information i.e.
List<Room> roomList = new ArrayList<Room>();
for(int i = 0; i < rooms.size(); i++){
if(rooms.get(i).roomPrice == searchRoomPrice){
roomList.add(rooms.get(i));
}
}
for(Room room : roomList){
System.out.println("Room Number: " + room.roomNum);
System.out.println("Room Type: " + room.roomType);
System.out.println("Room Price: " + room.roomPrice);
System.out.println("Balcony: " + room.hasBalcony);
System.out.println("Lounge: " + room.hasLounge);
System.out.println("Email: " + room.eMail);
System.out.println("-------------------");
}
I notice 2 things:
You are using a break; here:
if(rooms.get(i).roomPrice == searchRoomPrice){
selectedRoom = rooms.get(i);
break;
}
So you are stopping the loop after the first match.
Here:
for (int i = 0; i < lines.size() - 1; i++)
Is there a reason to use that minus 1?

I have created a counting game and I have tried to create a highscore method.

return lines;
}
}
Code is trying to open a handle to a non-existent file by the name 'Highscores'.
Problem is being caused by the following line of code :
BufferedReader inström1 = new BufferedReader
(new FileReader("Highscores"));
The solution would be to create this file upfront, at the beginning of the program and write default contents into it.
Here is how you can go about doing it.
private static void createHighScoreFile() throws IOException {
PrintWriter printWriter = new PrintWriter
(new BufferedWriter
(new FileWriter("Highscores")));
printWriter.write("0\n");
printWriter.close();
}
public static void main(String[] args) throws IOException {
createHighScoreFile();
DecimalFormat df = new DecimalFormat("0.00");
There is also one more issue related to reading the contents of the file.
The condition in the for loop attempts to read an extra line from the file, which turns out to be null always. It needs to be fixed this way.
for (int i = 0; i <= rader; i++) {
to
for (int i = 0; i < rader; i++) {
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.

I need some assistance with my program. Using an example program that was similar I was able to get the basic layout of everything I needed to do. Right now my main questions is if my code is correct for the first part. I want it to read the data from my data file into a parallel array. I included my entire program for reference of the layout, but for now I'm just trying to read the data file into an array. Any help is greatly appreciated. Let me know if more information is needed or if my formatting is wrong.

To begin, your code is VERY confusing and violates several OOP programming conventions.
The first (and most egregious) problem is that your static class Patient_Reports contains the main method but does not utilize this static entry point to declare an object or advance. So, it would behoove you to reformat your code like this:
public class Patient_Reports {
Patient_Reports fields...
public Patient_Report() {
//start work here in Constructor
}
Patient_Reports methods...
public static void main(String[] args) {
new Patient_Reports();
}
}
To address your main question, you would want to have some sort of generalized method you could call within your class like this:
public static void writePatientReports(int[] id, String[] patient,
String[] doctor, String[] surgery, double[] cost) {
BufferedWriter Student_file = new BufferedWriter(new FileWriter("patient.txt"));
for (i=0; i<=count; ++i)
{
//put "," between each data item in the file
Student_file.write(id[i] + "," + patient[i] + "," + doctor[i]+ "," + surgery[i] + ","+ cost[i]+ ",");
//write a new line in the file
Student_file.write("\n");
}//for loop
Student_file.close();
}
The reason you were getting errors is because you had no methods attached to Patient_Reports like write() or newLine(). And even if you had, you would have needlessly declared Student_file as a BufferedWriter object.
Further, you would do greatly in furthering your knowledge of Java and general OOP by reading Java Code Conventions
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
