    Default need Help to get this program running

    Question:
    Write a program that will calculate the cost of a ticket order and display the receipt for the customer on the screen. There are 2 ticket prices: adult, and senior citizen. Adult seats are $4.50 and senior citizen seats are $3.50. If more than 5 senior citizen tickets are purchased, the customer gets an extra 20% off the of the ticket order. If more than 10 regular seats are purchased, the customer gets an additional 10% off the cost of the order. A customer can only place an order for one type of ticket. Output the type of ticket purchased, the number of tickets purchased, the gross cost, the amount of the discount, and the final cost of the order.

    I am having errors with incaompatible varriables comparing float with doubles. Can someone please help me solve this program running.
    Thanks a lot

    Default Re: need Help to get this program running

    I tried running it now, but it does not really do any calculation or displays any error message if i enter any char other than adult or senior,
    So basically, it is not running anything that it was supposed to be, or is not calculating any calculations.

    --- Update ---

    This is what I have for my codes


    public class lab3
    {
     
       static Library myLib;

             Library myLib          = new Library();                 //Instance the Library class
             int ticketNum;                                          //Number of Tickets
    		 char adult;                                             //Ticket Type
    		 char senior;
    		 char ticketType;
    		 final float ADULT_SEAT = 4.50f;
    		 final float SENIOR_SEAT = 3.50f;
    		 final float ADULT_DISCOUNT = 0.10f;
    		 final float SENIOR_DISCOUNT = 0.20f;
    		 float totalCost;                                        //total cost of the tickets
    		 float grossCost;                                        //gross cost without discount

    Can you explain what problems you are having?
    Copy the contents of the console window and paste it here and add some comments describing the problems.

    Ticket Cost :0.0
    Discount Amount :0.0

    Because you are using non standard java classes: Keyboard and Library, it is not possible for me to test the code the same way you are. When I hard code some values in the code:
    			ticketType = 's'; //>>>>>>>>>Keyboard.readChar(); 
             	ticketNum = 3; //>>>>>>>>>Keyboard.readInt();
    I get this output:
     
    			   Scheemaker Stadium Ticket Receipt 
    			   ---------------------------------- 
     
    		Ticket Type          :s
    		Number of Tickets    :3
    		Ticket Cost          :0.0
    		Discount Amount      :0.0
    		Final Cost           :13.5

    Default Need Help Getting codes In

    Lab: There are 2 ticket prices: adult, and senior citizen. Adult seats are $4.50 and senior citizen seats are $3.50. If more than 5 senior citizen tickets are purchased, the customer gets an extra 20% off the of the ticket order. If more than 10 regular seats are purchased, the customer gets an additional 10% off the cost of the order. A customer can only place an order for one type of ticket. Output the type of ticket purchased, the number of tickets purchased, the gross cost, the amount of the discount, and the final cost of the order.

    Pseudo-code:

    INPUTS
    Ticket Type Char
    Number of Tickets Integer

    CONSTANTS
    adult = 'a'
    senior= 's'
    adults seat = $4.50 per ticket
    senior seat = $3.50 per ticket

    CALCULATION AND PROCESS
    Final Cost = Gross Cost - Discount
    Gross Cost = adult/senior seat * number of tickets
    If senior tickets are purchased 5 or more then they will get 20% discount
    If adults tickets are purchased 10 or more then they will receive 10% discount

    Discount = gross cost * discount rate
    Validate if the ticket type is valid ticket type: senior or adult.
    if it is invalid display a error message and prompt them to try again

    OUTPUT
    Receipt:
    Ticket Type :
    Number of Ticket:
    Gross Cost:
    Discount: If applicable
    Final Cot
