  • Flashing taskbar using Java (a la pidgin || MSN)

    - by jex
    I'm looking for a push in the right direction. I have a simple chat program, written totally in Java, and am looking for a way to get the Taskbar icons to flash. Preferably in a manner similar to Pidgin, or MSN. I'm hoping for a platform independent solution, as there are both Linux and Windows users, and preferably totally in Java.

  • Java 2D Drawing Framework

    - by Yan Cheng CHEOK
    Currently, I am using JHotDraw https://sourceforge.net/projects/jhotdraw/ as Figures Drawing Framework in my application. JHotDraw is a two-dimensional graphics framework for structured drawing editors that is written in Java. It is based on Erich Gamma's JHotDraw, which is copyright 1996, 1997 by IFA Informatik and Erich Gamma. I was wondering, besides JHotDraw, do you try out any Java 2D Drawing Framework, which is worth a try?

  • Covariance in Java

    - by Bobby
    Why does the following not work in Java? It would work in C#: public static final List<String> Split(String str, char delimiter) { if ((str == null) || "".equals(str)) { return new CopyOnWriteArrayList<String>(); } } I get an error saying this method has to return List. CopyOnWriteArrayList implements the List interface. Why does covariance not apply on return values in Java?

  • help with making a password checker in java

    - by Cheesegraterr
    Hello, I am trying to make a program in Java that checks for three specific inputs. It has to be 1. At least 7 characters. 2. Contain both upper and lower case alphabetic characters. 3. Contain at least 1 digit. So far I have been able to make it check if there is 7 characters, but I am having trouble with the last two. What should I put in my loop as an if statement to check for digits and make it upper and lower case. Any help would be greatly appreciated. Here is what I have so far. import java.awt.*; import java.io.*; import java.util.StringTokenizer; public class passCheck { private static String getStrSys () { String myInput = null; //Store the String that is read in from the command line BufferedReader mySystem; //Buffer to store the input mySystem = new BufferedReader (new InputStreamReader (System.in)); //creates a connection to system input try { myInput = mySystem.readLine (); //reads in data from the console myInput = myInput.trim (); } catch (IOException e) //check { System.out.println ("IOException: " + e); return ""; } return myInput; //return the integer to the main program } //**************************************** //main instructions go here //**************************************** static public void main (String[] args) { String pass; //the words the user inputs String temp = ""; //holds temp info int stringLength; //length of string boolean goodPass = false; System.out.print ("Please enter a password: "); //ask for words pass = getStrSys (); //get words from system temp = pass.toLowerCase (); stringLength = pass.length (); //find length of eveyrthing while (goodPass == false) { if (stringLength < 7) { System.out.println ("Your password must consist of at least 7 characters"); System.out.print ("Please enter a password: "); //ask for words pass = getStrSys (); stringLength = pass.length (); goodPass = false; } else if (something to check for digits) { } }

  • Java GUI Overlay

    - by seurimas
    Hey, I want to make an little window like the sort of thing used by Teamspeak/Ventrillo or Steam/xFire where a window can be shown while still in a fullscreen game using Java. There was a similar question/answer ("How to create an overlay window in Java?") but that doesn't work for the particular game (EVE) whereas the previously mentioned overlays work just fine. What's the missing element? Or is it an entirely different method?

  • Java Hardware Acceleration

    - by Freezerburn
    I have been spending some time looking into the hardware acceleration features of Java, and I am still a bit confused as none of the sites that I found online directly and clearly answered some of the questions I have. So here are the questions I have for hardware acceleration in Java: 1) In Eclipse version 3.6.0, with the most recent Java update for Mac OS X (1.6u10 I think), is hardware acceleration enabled by default? I read somewhere that someCanvas.getGraphicsConfiguration().getBufferCapabilities().isPageFlipping() is supposed to give an indication of whether or not hardware acceleration is enabled, and my program reports back true when that is run on my main Canvas instance for drawing to. If my hardware acceleration is not enabled now, or by default, what would I have to do to enable it? 2) I have seen a couple articles here and there about the difference between a BufferedImage and VolatileImage, mainly saying that VolatileImage is the hardware accelerated image and is stored in VRAM for fast copy-from operations. However, I have also found some instances where BufferedImage is said to be hardware accelerated as well. Is BufferedImage hardware accelerated as well in my environment? What would be the advantage of using a VolatileImage if both types are hardware accelerated? My main assumption for the advantage of having a VolatileImage in the case of both having acceleration is that VolatileImage is able to detect when its VRAM has been dumped. But if BufferedImage also support acceleration now, would it not have the same kind of detection built into it as well, just hidden from the user, in case that the memory is dumped? 3) Is there any advantage to using someGraphicsConfiguration.getCompatibleImage/getCompatibleVolatileImage() as opposed to ImageIO.read() In a tutorial I have been reading for some general concepts about setting up the rendering window properly (tutorial) it uses the getCompatibleImage method, which I believe returns a BufferedImage, to get their "hardware accelerated" images for fast drawing, which ties into question 2 about if it is hardware accelerated. 4) This is less hardware acceleration, but it is something I have been curious about: do I need to order which graphics get drawn? I know that when using OpenGL via C/C++ it is best to make sure that the same graphic is drawn in all the locations it needs to be drawn at once to reduce the number of times the current texture needs to be switch. From what I have read, it seems as if Java will take care of this for me and make sure things are drawn in the most optimal fashion, but again, nothing has ever said anything like this clearly. 5) What AWT/Swing classes support hardware acceleration, and which ones should be used? I am currently using a class that extends JFrame to create a window, and adding a Canvas to it from which I create a BufferStrategy. Is this good practice, or is there some other type of way I should be implementing this? Thank you very much for your time, and I hope I provided clear questions and enough information for you to answer my several questions.

  • Recommended Bean Utility Libraries for Java

    - by Jim Ferrans
    I'm looking for a good, well-supported, and efficient Java library that uses reflection to automate JavaBean operations. These include making a deep copy of an arbitrary bean hierarchy (with nested lists and maps of beans), comparing two bean hierarchies for deep equality, and "transmorphing" one bean to another of a different class. Some possibilities include Apache Commons BeanUtils, Spring's BeanUtils, and Java's Bean support. Which libraries would you recommend?
