Thread: Need help with Hotel booking math.

Hello everyone I'm working on a project for java class and I'm not advanced enough to do anything fancy, I have the basics of the program but for some reason it never adds up right. Can anyone help me correct this issue? thanks. Also i changed the name of doubleroom to roomroom because I thought doubleroom was messing with the math but apparently not lol.

import java.util.Scanner;
 
class resort4
{
	public static void main (String[] args)
	{
		int staytype;										//create int, some with values, some get values later.
                int roomtype;
		int weekdayrate = 5;
		int weekendrate = 20;
		int holidayrate = 50;
		int smokingroom = 40;
		int handicaproom = 10;
		int nonsmokingroom = 50;
                int book1;
                int book2;
                int book3;
                int keepgoing;
                int keepgoing2;
                int stayday;
                int finalprice = 0;
                int singleroom = 60;
                int roomroom = 100;
                int VIP = 500;

Define what "adding up right" would be. Show a sample run and describe how it should be different. Point to the code causing the problem, if possible.

A single room, one night stay, with a week day rate should come out to be 65. For some reason it shows 615, I have no idea whats messing it up o.Ojavaprobs.jpg

A key to understanding how to fix code to help someone is being able to duplicate their results. That usually requires knowing the inputs they've used to arrive at their results and understanding why the results are incorrect. That's why I asked for a sample run that you didn't provide. You can usually copy and paste from the console the results of your run to provide the sample run I've asked for, and that would answer Norm's question.
