I need to make a java program which accepts input from user in form of item Code, quantity and rate and then display the total amount as well as discount .
the condition for getting discount is like
if the amount is greater than 5000 than discount is 10% of amount. i want to display amount and discount amount calculated ...my code works nice till it calculates amount but when moving to next step for calculating discount it shows error.

plzzz hep me out ...is there any error in my code??
am new to Core java
thank you...

import java.io.*;
class AMOUNT
{
public static void main(String args[])
{
Double discount= 0.0 ;
InputStreamReader istream = new InputStreamReader(System.in) ;
BufferedReader br= new BufferedReader(istream);
System.out.println("Welcome to My Java Program");
try
{
System.out.println("enter the item code:");
String code=br.readLine();

System.out.println("enter your quantity:");
String quantity=br.readLine();

System.out.println("enter the rate:");
String rate=br.readLine();

int qty=Integer.parseInt(quantity);
int Rate=Integer.parseInt(rate);

int amnt= qty*Rate;
System.out.println("your amountis"+amnt);

if(amnt > 5000)
{
discount=Double.parseDouble(br.readLine());
discount= 0.1 * amnt;
System.out.println("your discount is"+discount);
}
else
{

System.out.println("you dont have discount");
}
}
catch (Exception e)
{
System.out.println("error");

}
}
}

This is not a java related issue,It is a permission related issue.
So check whether you have the permission to create file in "c" drive.

look, I don't known why you can't save your java resource files in C:\\, but I can explain you what I did with the rights the last time I reinstall my Laptop, I'm running my PC with Windows 8 Pro 64 bit, look, let me explain you what I did:
1 - Right Click on the System Drive (C)
2 - Properties
3 - Security
4 - Advanced
5 - Auditing and Continue
6 - Add your user name to the list and give them all the rights
7 - Ready

With this work...

this is not a issue related to java.
first of all check whether you have proper rights to access C drive or not.
if not then login as administrator

You could use a simple Array[^] or one of the collection classes[^].

No idea. You really need to spend some time thinking about what problem you are trying to solve, and learning how to express your question in clear technical terms.
