Cashier Program Help

[Azzy]

I'm making this cashier program in java, my first actual program, and instead of printing the right values, it keeps printing the price as 49.

If anyone can help, I appreciate it.

code:

import java.io.*;  import java.text.*;    public class cashier  {         public static void main (String[] args)throws Exception         {                DataInput keyboard = new DataInputStream(System.in);                String temp;                char response;                                                  double price = 0.00;                double pst = 0.00;                double gst = 0.00;                double total = 0.00;                double pstper = 0.07;                double gstper = 0.08;                                System.out.println ("What is the cost of the item you are buying?");                price = System.in.read();                                pst = price * pstper;                gst = price * gstper;                total= price + gst+ pst;                                System.out.print ("Cost    $");                System.out.println (price);                System.out.print ("PST     $");                System.out.println (pst);                System.out.print ("GST     $");                System.out.println (gst);                System.out.print ("Total   $");                System.out.println (total);         }           }

just a thought... u didnt calculate the pst/gst/total price

[wtd]

code:

import java.lang.*; import java.io.*; import java.text.*; class MoneyReader extends BufferedReader {         public MoneyReader(Reader in) {                 super(in);         }         public double getMonetaryAmount() throws IOException {                 return Double.parseDouble(readLine());         } } public class Cashier {         private static MoneyReader keyboard = new MoneyReader(new InputStreamReader(System.in));         private static DecimalFormat moneyFormat = new DecimalFormat("$#,###,##0.00");         public static void main (String[] args) throws IOException         {                 double pstRate = 0.07;                 double gstRate = 0.08;                 System.out.println("What is the cost of the item you are buying?");                 double price = keyboard.getMonetaryAmount();                 double pst = price * pstRate;                 double gst = price * gstRate;                 double total= price + gst + pst;                 System.out.println("Cost    " + moneyFormat.format(price));                 System.out.println("PST     " + moneyFormat.format(pst));                 System.out.println("GST     " + moneyFormat.format(gst));                 System.out.println("Total   " + moneyFormat.format(total));         } }

ha, wtd, i doubt he under stands throws and catches

I didn't introduce anything in terms of exceptions that wasn't already in his original code.

Though now I have.

I declared that a NumberFormatException might be thron by the calls to Double.parseDouble.

code:

import java.lang.*; import java.io.*; import java.text.DecimalFormat; class MoneyReader extends BufferedReader {         public MoneyReader(Reader in) {                 super(in);         }         public double getMonetaryAmount() throws IOException, NumberFormatException {                 return Double.parseDouble(readLine());         } } public class Cashier {         private static MoneyReader keyboard = new MoneyReader(new InputStreamReader(System.in));         private static DecimalFormat moneyFormat = new DecimalFormat("$#,###,##0.00");         public static void main (String[] args) throws IOException         {                 double pstRate = 0.07;                 double gstRate = 0.08;                 System.out.println ("What is the cost of the item you are buying?");                 double price = keyboard.getMonetaryAmount();                 double pst = price * pstRate;                 double gst = price * gstRate;                 double total= price + gst + pst;                 System.out.println("Cost    " + moneyFormat.format(price));                 System.out.println("PST     " + moneyFormat.format(pst));                 System.out.println("GST     " + moneyFormat.format(gst));                 System.out.println("Total   " + moneyFormat.format(total));         } }
