Dear all, What am I doing wrong 1

[rocknrisk]

Dear all,

What am I doing wrong here. If I input, say, 1025 then I get 49 as my netCost. Why is the program changing my figure. This is driving me up the wall. I have the feeling, I'm making a very simple error, I just have no idea what it is

Thank you in advance and Merry Festive Season,
Clinton

// ***************** Code ****************
import java.io.IOException;

public class NewYorkPlusTax {

public static void main(String[] args) {

double netCost;
double grossCost;
double taxAmount;

double TAX = 8.25; // this is a percentage

System.out.print("Enter Cost-Before-Tax of Item: "
try {
netCost = (double)System.in.read();
// netCost = Double.valueOf(System.in.read()).doubleValue();
System.out.println("Item price = " + netCost);

taxAmount = netCost * TAX / 100;
System.out.println("Tax on Item = " + taxAmount);

grossCost = netCost + taxAmount;
System.out.println("Total Amount = " + grossCost);

} catch (IOException ioe) {
System.out.println("User Error"
}
}
}

Try this:

import java.io.IOException;
import java.io.BufferedReader;
import java.io.InputStreamReader;

public class test {

public static void main(String[] args) {

double netCost=0.0;


try {

BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
String temp = in.readLine();
try{

netCost = Double.parseDouble(temp);
}
catch(NumberFormatException nfe) {
System.out.println("Numbers only please, try again."
}

System.out.println("Item price = " + netCost);

} catch (IOException ioe) {
System.out.println("User Error"
}
}
}

There could be a better way but this solution should work. ;-)

Cheers
