Yes, there was that. There is also your while loop. You've made it better but I don't think you want that semicolon there. You should also consider using String.format here System.out.println("The result of your addition was "+result+". \n");
My lazy attempt at this example essentially places the user in an infinite loop allowing them to specify very large positive or negative numbers to be added to a running total, hitting enter displays the running total as it stands.
Code:
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import javax.swing.JOptionPane;
import java.math.*;
public class Main {
public static void main(String[] args) {
try
{
BigDecimal accumulatedTotal = new BigDecimal(0);
int i = 1;
BufferedReader buff = new BufferedReader(new InputStreamReader(System.in));
while(true)
{
try
{
System.out.print(String.format("Enter value %d here (hit enter to see current total): ", i));
BigDecimal inputVal = new BigDecimal(buff.readLine());
accumulatedTotal = accumulatedTotal.add(inputVal);
i++;
}
catch (NumberFormatException ex)
{
System.out.println(accumulatedTotal.toString());
}
}
}
catch (IOException ex)
{
JOptionPane.showMessageDialog(null, "Oh Dear");
ex.printStackTrace();
}
}
}
