 | A couple questions before I even attempt this project... Is it possible to create a VoIP application in Java? Is it posssibe to do this using standard libraries? If you can't make one with standard libraries, which libraries are needed to accomplish this? Also, is this a good Introduction to …  |
| | Hey everyone, I'm looking for some help with coming up with a system to communicate data between client and server sockets. I was thinking of a command system, but that would only work when the client is sending a request to the server, not when the server is returning data …  |
| | I'm creating an application that with continuously attempt to run a list of programs until they are open. I'm having an issue when it comes to programs that require administrative priveleges however.

 | I'm sure it wouldn't hurt to put it through all the popular Encryption Algorithms? Worse that can happen is you get the wrong result. |
| | I have this method that is used to set the columns and data in the listview based on a string. I'm not sure how to add the columns I need programactically. I need to use different data types though. private void populateLeaderBoardList() { string btnContent = (string)btn_exportLeaderBoard.Content; if (btnContent.Contains("Totals")) { … |
| | I'm having some issues with my BSP Dungeon Generation and I'm not sure why! I'd greatly appreciate the help :) Occasionally I'll get an IllegalArgumentException in RandomHelper. That may help, but it's not the issue because it only happens rarely. As you can see, [this image](http://puu.sh/nb9Ir/70efbe5e81.png) shows that the Rooms … |
| | Why is my finally block not firing after projectDCThread.join() is called? This method IS in a class that implements Runnable, however it's not overriding the deprecated stop() method. public synchronized void stop() { if(isRunning || safeCloseRequested) { try { isRunning = false; projectDCThread.join(); } catch (InterruptedException e) { Logger.append("Exception thrown … |
| | Re: java to notepad Perhaps writing input from your Java program to a text file is what you're referring to. If that's the case, search the forums for something along the lines of "writing to a text file". |
| | Flickering occurs when Active Rendering with JPanel, not sure why as I've done this before (couldn't find source code of that project however). Relevant Code: Graphics g = projectDCWindow.getWindowGraphics(); // Gets the Graphics Object from a JFrame g.setColor(Color.BLACK); g.fillRect(0, 0, (int) ProjectDCInfo.getDefaultWindowSize().getWidth(), (int) ProjectDCInfo.getDefaultWindowSize().getHeight()); // Clears the screen projectDCGSM.get().render(g); // … |

| | Looking for complete code snippets to read through and try to understand. Post them below and I'll post back with what I think it does. |
| | Curious who's all used MiGLayout and what everyone's thoughts are on it. Is it a prefered layout over others? If so, which? What do you like and dislike about it? Is there any other 3rd Party Layout's you would recommend? What features do they have that make them recommended? |
| | I was wondering if it would be more efficient to render a single BufferedImage instead of rendering a bunch of BufferedImages in a double for loop? I have an idea of how to do it, I just don't know what methods in BufferedImage you would use to create the bigger … |
| | I'm used to using AWT's Canvas and BufferedImage and things like that. I've switched from using Canvas for drawing, to using a JPanel and I'm blown away by the efficiency. I intend on fully using Swing for all of my GUI. My question is, what is Swing's equivalent of BufferedImage? |
| | So I have a few concerns about the new Categories after a while of using them and I thought this would be the best way to express them. I have noticed that it seems to be a little more difficult to navigate the forums and theres a few reasons I …  |
| | I know you're not supposed to use Lightweight Components like JFrame with non-Lightweight Components like JFrame, so my question is, what do you use with a Canvas? Is there also some example code for it? Thanks! |
| | Is there a way to require a subclass to call super explicitly in it's constructor? |
| | I'm looking for what exactly is a Vector3 (or any Vector for that matter) and also what a Quaternion is in code? What are the variables types? Should you have multiple classes for each type? Thanks!  |
| | I have a custom class which extends JPanel and overrides the paintComponent() method. Here's what that looks like: @Override protected void paintComponent(Graphics g) { if(redrawRequested) { g.setColor(ETCH_BACKGROUND_COLOR); g.fillRect(0, 0, owner.getAppWidth(), owner.getAppHeight()); redrawRequested = false; } g.setColor(Color.BLACK); g.fillRect(pointX, pointY, PIXEL_SIZE, PIXEL_SIZE); } The same custom class also implements KeyListener. I am … |
| | Re: Nested Loops? I'm not sure why your code is even compiling as the less than sign should be on the left side of the equals sign. This should be how it is in any case, less than, greater than, equal. Anyway, on with the question, you should be setting one of your …  |
| | I want to iterate over a List in a 2D way, basically starting at the center and working my way around in a "circular" fashion. The List is a List of type Chunk and Chunks store a Vector 3 position. I also have a Player which has a Vector3 position. …  |
| | I'm curious, when setting the default close operation for JFrames, should you use JFrame's constants or WindowConstants' constants? As far as I can tell they're the same. Although, IntelliJ (not tested on other IDE's) prefers WindowConstants' EXIT_ON_CLOSE at least. So basically my question is, which one should be used? Which … |

Will retry during next Iteration."); return false; } … |

| | I can swap two tiles, however, when I need to shuffle them, I need each tile to have a unique position. I've tried setting up array's for the x and y position of both the tiles to be swapped checking against the randomly generated number to make sure it's position … |
| | I'm painting a grid on the JPanel and trying to scroll the grid with a JScrollPane. I have a feeling the scrollpane is getting the actual size of the panel, instead of the size including what is not being shown. Something along those lines at least, I can't quite wrap … |
| | I have a GUI with two JSpinner's and a Spinner Model attached to each of them. When changing one value, the other changes. I suspect this is because I'm using the same model. This is obviously not what I intend to do, is there a better way than creating another … |

| | So I know in a Tile Based game its more effecient to have static final instances of each tile, then populate your array with those instances. But what about Rendering? You have to pass the position that tile should be rendered into your method you use for rendering. Is there … |
| | I would recommend if this thread is not solved, that you do not mark it as such. |
| | There's no need to post more code right now, first start out by posting the Stack Trace. The Stack Trace is basically the error that gets printed out when the NPE is encountered. It contains some information that will help us guide you to sorting out the problem. |

| | If I'm not mistaken, which I could be because I've never even heard of a Deque, You need some sort of List to put Objects into. Then I would use that List's methods to add and remove Objects to and from, as well as getting the Objects from that List. |

 | Java Doc: Scanner.nextLine(); "Advances this scanner past the current line and returns the input that was skipped." Try using Scanner.next(); Also, its better to move everything into methods, and calling them. Also, do some research on BufferredReader's. Ex. BufferedReader in = new BufferedReader(new InputStreamReader(System.in)); inputString = in.readLine(); |
