radio button with spinner to create an answer in a textarea box
basically i'm new to java and i'm trying to make a ticket machine and i'm stuck on how to make it so that once a radio button is selected and a value from a spinner is selected it would both times together to give me a value in a textarea box but i'm unsure of how to do this
could anyone give me some tips or useful advice on how to tackle this please

Put a listener on them? That should be covered in the tutorial for each.

i read through it but still don't really understand what to do
Re: radio button with spinner to create an answer in a textarea box
What didn't you understand? What did you try? Keep in mind that to really read through the Swing tutorials should take days or weeks, not minutes or hours. If you want help, you should provide an SSCCE that demonstrates what you tried and where you're stuck, and you should ask a specific technical question. It's hard to answer "how do I do this" with anything other than links to the tutorials.

Re: radio button with spinner to create an answer in a textarea box
I don't know what to tell you that I haven't already said. Sounds like a job for a listener. And that's not an SSCCE- if you want help with adding a listener, write a small program that adds a listener to a single component, or show us where you're having trouble with that one step. We don't need any of that extra stuff.

Re: radio button with spinner to create an answer in a textarea box
i'm having trouble with this step
PHP Code:double tp = 0;
int noticket = Integer.parseInt(""+numtick.getValue());
if (single.isSelected()) tp = 1.40;
{
ticket.setText(pounds.format(tp));
stp.setText(pounds.format(tp));
}
if (Return.isSelected()) tp = 2.40;
{
ticket.setText(pounds.format(tp));
stp.setText(pounds.format(tp));
}
if (zoneA.isSelected()) tp = 3.80;
{
ticket.setText(pounds.format(tp));
stp.setText(pounds.format(tp));
}
if (zoneAB.isSelected()) tp = 5.50;
{
ticket.setText(pounds.format(tp));
stp.setText(pounds.format(tp));
}
Re: radio button with spinner to create an answer in a textarea box
These two statements are being compiled each time.......ticket.setText(pounds.format(tp)); stp.setText(pounds.format(tp));
Try looking at if-else
