I want my Listener 1 to work for now. Which is the data button.

This code works when i run the driver class. However, i already have the driver class and need help in this panel.

I just cant seem to figure out how to get data button to work. i want that button to take user doubles and show it in label, that i named as data(same name as the button name).

Yes the Listener is called when the data button is pressed.
I want to show it in label named "data".
I dont know what method to call to set the text of a label (New to Java sorry).

JLabel(String text), i figured out this code is needed to set text of label. Now what should i do to proceed.
