You can't declare methods within other methods, so those that you have crammed into the switch statement have to be moved out.

And I agree with Niek_e: airing this out in a public thread in Community Feedback is probably not the most productive way to address the situation.

Use a JTable. What you are describing is not a list.

You could override toString() on the object you add to JList to present the description you want, but if you want to present those as separate fields, use a table.

You access that inner array list just like I indicated above. I still don't understand why you need to create a new one, but then I don't know what you're trying to do with that structure. Here's a loop that will print each element, maybe that will help answer your question.

ArrayList playerinfo = new ArrayList();
for (int i=0; i< playerinfo.size(); i++){
    ArrayList innerList = (ArrayList)playerinfo.get(i);
    for (int j=0; j<innerList.size(); j++){
        System.out.println( innerList.get(j).toString() );
    }
}

If your ArrayLists are declared with generics, you won't need the cast.

Try removeAll(Collection) instead of remove(Object).

You just need to "get()" the info that is there. The code you posted is trying to create a new ArrayList.

It looks more like you want playerinfo.get(0).get(0) .

Try adding a revalidate() and possibly a repaint() in your runnable after you set the new screen.

Sounds like you just need to tweak your coordinate math a little. If you got a solid triangle you are on the right track.

Edit: Oops, cross posted with santiagozky. I would agree that you should add more than if you don't want solids.

Just a note: it's preferable to override paintComponent() in most cases instead of paint(), since paint() is also responsible to painting children and the border.

Take a look at OpenMap.

That's because you moved the code into the anonymous listener. If you aren't going to define that method on your class then remove the "implements ActionListener" from your class declaration.

In your Netbeans installation directory, go to "etc/netbeans.conf". There you will find an entry for "netbeans_jdkhome".

Well, looking at that brace on line 64, your code to add the listener is not in a method at all. So you've left out some other code in your post or that piece above won't even compile.

The post is over four years old. Not everything on the web persists forever.

Your example is only a case of poor variable naming. Why would you name a boolean "state"? What would "state equals true" mean in a logical description of the program flow? If it is truly a boolean state then you can easily assign a name that accurately reflects that binary nature.

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

add(noSelectionButton);

in your code above. You created the button but didn't add it to the panel.)

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.

... and it always makes me wince).

Me too. Not only is it unnecessary, the code just reads a whole lot cleaner without them.

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 it

CO2Footprint 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.

That method doesn't return anything though, so trying to capture a return value from it won't get you anywhere.

Walk through and match up your braces.

Using the pattern (\w+?[RK]) with the regex Matcher.find() method will capture all of those groups except for the last one, which doesn't end with R or K.

Edit: This pattern \w+?[RK]|\G\w++$ seems to produce the result you wanted.

Pattern pat = Pattern.compile("\\w+?[RK]|\\G\\w++$");
String input = "AMLARMLAKFGFP";
Matcher matcher = pat.matcher(input);
while (matcher.find()){
    System.out.println(matcher.group());
}

(Yes, the HTML page source is just marked up text)

Much appreciated response ezzaral, just one quick question when reading the text from the url, does that automatically read the source of the page?

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

You can start with Reading Text From A URL and Regular Expressions.

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 same that behaves itself. It's worth noting that these two versions only differ in what kind of socket is created to make one the "server". They could be coalesced to a single class. (It's also a quickly slapped together modification that doesn't properly handle exceptions or shut down properly and close io streams :) )

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. You have to separate the animation updates from the painting. One way to do that would be to wrap the code you currently have in the show() method into a small Runnable class

class LineAnimation implements Runnable{
        public void run() {
            Vector<Line> LINES = this.lines(POINTS);
            Vector<Line> PWLINES = new Vector<Line>();
            for (int i = 0; i < LINES.size(); i++) {
                PWLINES.add(LINES.get(i));
                this.G.transfer(POINTS, PWLINES);
                this.G.repaint();
                try {
                    Thread.sleep(500);
                } catch (Exception e) {
                }
            }
        }
    }

and start a new thread with that Runnable in your show method

Thread lineAnim = new Thread(new LineAnimation());
lineAnim.start();

As BestJewSinceJC mentioned, a Swing Timer can also be used for this.

Well, to get rid of that error, don't call methods that do not exist

helpMenu = menuBar().addMenu(tr("&Pomoc"));

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

Here at work we just use the XP look and feel and all of our time is taken up working on functional requirements. We don't have much time left to play with UI customizatoin. =\

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.

y u a hater 4 nikka wow is a good game everyone plays it u just mad cause u cant hit lvl 80

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 borderless, use setUndecorated(true);

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 pluggable look and feel and custom UI delegates to gain a greater degree of customization. Here is an overview of that architecture: http://java.sun.com/products/jfc/tsc/articles/architecture/

Your listener is setting the icon on whichever button i and j corresponds to

button[i][j].setIcon(imageO);

What you really want to do is getSource() from the mouse event and cast that to a JButton and set it's image.

JButton clickedButton = (JButton)e.getSource();

You could define a method like

private void enableLength(boolean enable){
   txtLength.setEnabled( enable );
   lblLength.setEnabled( enable );
}

so your if() code becomes

if (optBox.isSelected() ){
  enableLength(true);
}

That would be a little clearer to follow and a bit less repetition. You would have one method for each of your dimensions.

You have to actually create the JButtons in your array. You have only declared the array of references with this statement

JButton[][] button = new JButton[3][3];

You must still initialize those objects by adding

button[i][j] = new JButton();

in your loop before you try to do anything with them.

Um, waiting for a question perhaps?
