i am trying to have macromedia flash button send a double or a symbol like (+, =, &) to a java program. the java program will save the input on an arraylist. while the flash button sends doubles it simply puts them on the arraylist, but if a symbol comes in, then the items from the arraylist are removed and summed up.

so this is the code that i have. i do not want to use the showOPtionPane dialog boxes from the java library. i want jave to simply be able to receive input.

import javax.swing.JOptionPane;
import java.lang.*;
import java.util.*;
import java.io.*;

public class arrayList
    public static final String plus = "plus";
    public static final double TAX = 0.08;
    public static double subTotal = 0.00;
    public static double total = 0.00;
    public static void main(String[] args)
        String price = "";  // initialized the variable price to empty string
        ArrayList keypad = new ArrayList(); // create an arraylist and name it
                                            // keypad
        while (true) // continuous loop to stop when array is
                                    // empty
            try                     // read data from console
                BufferedReader in =
                    new BufferedReader(new InputStreamReader(System.in));
                //System.out.println("Enter price");
                price = in.readLine();
            catch (IOException ioe) // if error then catch error
            keypad.add(price);  // put data read from console into stack
            if (price == ("+"))   // if the data is a plus sign then add the items
                                // in the stack (subtotal key)
                keypad.remove(price); //remove the + sign from the stack
                for (int i = keypad.size() - 1; i <= 0; i--) // get all the data
                            // from the stack and continuously add them together
                    keypad.get(i);      // get item from stack
                    subTotal += i;      // add it to itself
                    keypad.remove(i);   // remove item from stack
                System.out.println("SubTotal is " + subTotal); // print subTotal
                                            // to console

thx in advance.....
