I have to make a program that outputs something similar to the appearance of a phone. With intractable buttons, (0 - 9) a T button that outputs "Calling" and an E button that outputs "End-Call"

Now i have that much done

Not the prettiest code i admit, but what i'm having trouble with is this
- I need the msg JLabel to appear on top of the buttons not below them
- I need to make it capable of holding more than one number at a time, anytime you push one now the thing is just reset.

- Any Suggestions???

To make the number not disappear as you type try this for each:

String prevText=msgLabel.getText();
                msgLabel.setText( prevText+String.valueOf( clicked ) );

What is the "it"? Is that the JLabel.
What String do you pass to the setLabel() method? Is that what you want to change?

Yeah, the JLabel is what shows the numbers, which in this case appear at the bottom of the frame.
I need it too appear at the Top of the frame, above the buttons.
I also need the JLabel to output the buttons i press,
so that as i press 5 than 1 than 2 it would show 512.
right now if i press 5, 1, and 2 it covers over the previous number, so the JLabel would show just 2.

Think of it this way: you have a variable with a value (5) and you want to add 7 to it:
var = 5;
would you do this:
var = 7; // set it to the value to be added
or this
var = var + 7; // add the 7 to the current value

Wouldn't that add the values Mathematically,
Then hitting 5 and 7 would print out 13.

Ah! I can't believe i never thought of changing it to a String.
I am however now getting "null" before my string of numbers when i push a button.
Also, how can i reset a string after i hit "E" or "End Call" ?
