Why not stick with the ButtonGroup? You can put both radio buttons and check boxes in the button group just fine. CheckboxGroup is for use with AWT Checkbox.

(By the way, you forgot...

You are trying to assign a single int value to an int[] array. You need to assign that int to a specific element in your array, such as
stateCode[count] = input.nextInt();

The compiler is usually very explicit in telling you what the problem is.

At a quick glance, one problem is that you used "Pow" instead of "pow". Java is case sensitive .

And what is your question? As I said, "it doesn't work" is not a question. Be specific.

"It didn't work" is not a question.

And use code tags if you post code.

Me too. Not only is it unnecessary, the code just reads a whole lot cleaner without them.if (isComplete) {...

You already have a thread on this question here:

Do not create multiple threads for the same question.

The literal value of a float in your code would be "6.0f", but printed output does not show that "f" unless you put it there explicitly.

Your output is perfectly fine.

Are you expecting it to print the "f"? Doubles and floats don't look any different as output.

So now you can create a CO2Footprint object and call methods on itCO2Footprint footprint = new CO2Footprint();
double[] glassReduct = footprint.calcGlassReductions();

Maybe you want to reverse line 23?

That isn't Java code. Perhaps you meant to post this in another forum?

Because you are calling that method statically but it is not declared as a static method. To call it as you have defined it, you would need to create an object of that type and call the method on it....

Walk through and match up your braces.

Using the pattern (\w+?[RK]) with the regex Matcher.find() (http://java.sun.com/javase/6/docs/api/java/util/regex/Matcher.html#find()) method will capture all of those groups except for the last one,...

Give it a quick try and you'd have a definitive answer. :)

You can start with Reading Text From A URL (http://www.exampledepot.com/egs/java.net/ReadFromURL.html) and Regular Expressions (http://java.sun.com/docs/books/tutorial/essential/regex/).

And don't you have about 5 threads started on this now?

My suggestion: learn how to type and communicate effectively. It will serve you well.

I think you are correct that the behavior did stem from some blocking, but this can still be simplified a great deal to work without a separate listening thread.

Here's a re-wired version of the...

The problem is that all of your code, including the thread.sleep() calls, are executing on the AWT event queue thread, which is the same thread that handles the repaint calls to update the display....

No, I hadn't seen anything about Nimbus as yet. It looks pretty nice.

Looks like you have a bit of work ahead of you. Let us know if you have specific questions about portions of it.

Or keep them in a List.

Absolutely brilliant.

It all comes down to the details of "changing the look". Some things are trivial, others are quite complicated. You asked a very general question.

If you just want to set the frame to be...

Call methods on "clickedButton". I wrote that to show you how to obtain a reference to the button that was clicked.

You can customize all kinds of things about how the UI appears. A lot is possible with the methods provided by the Swing components, but if that isn't sufficient it's possible to use the the...

Probably.

Agreed that this is more of a HTML/CSS question. Moving it over there. Carry on :)

Sounds like you probably need to fail then if you cannot show that you learned the material. Failing can be a great learning experience.
