}

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???

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.

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

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

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

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.

yes but think about it theoretically, you would use the old text of the label and add it to the new text.. have you tried what i suggested
see here also:http://docs.oracle.com/javase/7/docs/api/javax/swing/JLabel.html#getText() and http://docs.oracle.com/javase/7/docs/api/javax/swing/JLabel.html#setText(java.lang.String)

NormR1 563 Posting Sage Team Colleague · Answer 5 · 2012-02-08T23:35:01+00:00

Change the variable type from int to String.
Then what would be the results?

Hypnos_16 0 Junior Poster in Training · Answer 6 · 2012-02-08T23:53:55+00:00

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" ?
