this is the error I get from the last catch block:
Unreachable catch block for IOException. This exception is never thrown from the try statement body
import java.io.*;

The class compiles okay without it.
// try
// {
BufferedReader stdIn = new BufferedReader(
new InputStreamReader(System.in));
String userInput;
while (!choice.equals(null))
{
if(choice.equals("1"))
{
write.println("addProduct");
userInput = newProduct;
write.println(userInput);
userInput = newPrice;
write.println(userInput);
choice = "0";
}
else if(choice.equals("2"))
{
write.println("addSales");
userInput = newProduct;
write.println(userInput);
userInput = newAmount;
write.println(userInput);
choice = "0";
}
else if(choice.equals("3"))
{
write.println("getTotalValue");
choice = "0";
}
}
// }
// catch(IOException e)
// {
// System.out.println(e.getMessage());
// }
}
