Ok, sorry about the code. I took out the loop. What if I just put one output on the bottom? null? When I compile this, it goes through now, asks me for my info, but then doesnt output. Here is what I have-
...Code:import javax.swing.*; import java.awt.*; import java.util.*; public class Calculator{ public static void main (String[] args) { String inputString = JOptionPane.showInputDialog("Input...etc etc");Leave a comment:

Yeah, I know I do. Im downloading it right now (thanks for the link btw). Here's what I have-

What about floats? how about this-
This is what ive got-
Float.parseFloa t(result[0]) = n1;
Float.parseFloa t(result[2]) = n2;
switch (1)
{
case '+':
JOptionPane.sho wMessageDialog( inputString + " = " + n1 + n2);
Will that output 2 + 1 = 3? (I cant run it yet) Thanks...Leave a comment:

String a = result[0];
String b = result[1];
String c = result[2];
switch (b)
{
case +:
case -:
case /:
case *:

Oh alright, I gotcha on the outputs. As for the splits, how do I actually use them? Will the result change throughout the code as I use it for different things? What im asking, is can I name them or something? ThanksLeave a comment:

My requirements limit me to the one output, would this be easier to tokenize, and make tokens? Thanks!...Leave a comment:

Also, ive found references to arrays, so maybe thats my solution? If someone has a guide?

I need to make a calculator in which the user inputs 2 floating point numbers and an operation, with and output of the answer with the original equation. I think I need to use the split function, however I dont know what to do once it is split. Here is what I have so far-
