  • Vectors for a 2D/3D World in Java

    - by jax
    I reading about Mathematics in Games and am wondering what is the best way to represent a Vector location in Java. I know there is a Vector class but I don't think this is what I need. There is also a Matrix class which looks like it may be what I want (a 1 dimensional matrix maybe). In particular, if I were to create a location Vector such as: v(x,y,z) where x,y and z are the coordinates in 3D space, what would be the best way to represent this in Java. It would be nice if I could also add, subtract and find the dot-product of Vectors. ideas?

  • Converting java language output to Joomla language output

    - by jax
    in java if I run : Locale.getDefault().toString() I get zh_tw I am sending this to a joomla site and setting the language like this: $lang = &JFactory::getLanguage(); $lang->setLanguage( $_GET['lang'] ); $lang->load(); however the site requires the following format zh-TW It appears that if it is not in that exact format the language will not change. Is there a function somewhere in java or php that will convert the format for me? I realise that I could write the method myself like this: public static String convertLanguageToJoomlaFormat(String lang) { String[] parts = lang.split("_"); if(parts.length ==2) return parts[0]+"-"+parts[1].toUpperCase(); return lang; } but am unsure if there are any cases where the format changes for particular languages.

    - by davit-datuashvili
    first of all i am doing programs in java language this code is merely taken from web site i have not question about divide and conqurer algorithms but about function and it's argument here is code of ternary search def ternarySearch(f, left, right, absolutePrecision): #left and right are the current bounds; the maximum is between them if (right - left) < absolutePrecision: return (left + right)/2 leftThird = (2*left + right)/3 rightThird = (left + 2*right)/3 if f(leftThird) < f(rightThird): return ternarySearch(f, leftThird, right, absolutePrecision) return ternarySearch(f, left, rightThird, absolutePrecision) i am not asking once again how implement it in java i am asking for example how define function?for example let y=x^+3 yes we can determine it as public static int y(int x){ return x*x+3; } but here return ternarySearch(f, leftThird, right, absolutePrecision) function f does not have argument and how do such?please help me

  • convert flv to mp3 with Java

    - by krial
    Hi, I'm pretty new in developing programs in Java. I'm currently writing a program that converts a flv video into mp3. I have already written such a program in Visual Studio.net C#, but the Problem is, that it isn't cross platform compatible... I used the ffmpeg binary to convert the video into mp3, but I can't find ffmpeg binaries for Mac and Linux. (if so, I could start the specific binaries from java, depending on the OS) So I tried to convert the video with Xuggle, but the final mp3 has 0 bytes. My current code is the following: IMediaReader reader = ToolFactory.makeReader("video.flv"); reader.addListener(ToolFactory.makeWriter("music.mp3", reader)); while (reader.readPacket() == null) do {} while(false); Thanks in advance. p.s sorry for my bad english

  • Best way to notify several java applets/applications of a change on a server

    - by Dustin
    I need to know the best (fastest) way to have a server (preferably a php based one, but a jsp/servlet one could be set up as well using google app engine) notify several java applets/applications that a change has occurred to the data. The way i am picturing this to work will be very similar to that of the way i think an online java game (like Runescape) works User 1: Changes data on server. Server: returns success to User 1, notifies connected computers of change. Connected Computer 1: processes change, returns success to server. Connected Computer 2: processes change, returns success to server. Connected Computer 3: processes change, returns success to server. Connected Computer 4: processes change, returns success to server. I am hoping to have this entire process complete in half a second, and not involve polling as there will be long durations of nothing, followed by a sudden moment where 4 events happen in succession.

  • How can I install Java on Windows 7 without messing up the system?

    I've installed java 1.6.0_31 32bit on Windows 7 64bit system, but this installation messed up my system, e.g. when I start Google Chrome I get error Your preferences can not be read Visual Studio 2010 after launching shows error that The Application Data folder for Visual Studio could not be created The shortcut to the Downloads folder in Windows Explorer no longer works. Is there a way to install Java without messing up Windows 7? Or maybe this mess can be cleaned up after installation of Java, but how?

  • Google App Engine, Java, and HTTP Performance

    - by polyclef
    A friend and I are currently working on a turn-based game with chat with both desktop browser and Android clients, with Google App Engine as the server. We're using the Java API for GAE and using HTTP for communication with the server. We've implemented simple chat functionality, and we're getting undesirable latencies 1-3 seconds from both the browser and Android clients while just posting simple one-word chat messages. My friend thought it would be best to use XMPP instead of HTTP, but we want to use a Google Accounts cookie for authentication from the Android client, and according to the GAE documentation, XMPP clients cannot use a Google Accounts cookie and must use the user's password. Does anyone have any suggestions as to where the latency might be coming from, how to troubleshoot it, and/or what to do about it? Also, is anyone aware of any opensource implementations of chat (or something similar) on GAE done in Java? Can't seem to find any.

  • What would you recommend for a undergraduate final year project?

    - by Thach Tran
    To narrow down the question, please suggest web-based topics only. To be honest, I'm struggling to find one for myself :) I'm doing Computer Science and looking for a web-based, individual project. A suitable topic would have a certain degree of novelty, so while you guys browsing the web everyday, what kind of things you expect but haven't come up before. Sorry for my lousy English :)

  • Create "INSERT" statements from mySQL database in Java

    - by girdus
    Does anyone know of any good libraries or scripts out there which will allow me to point to any mySQL table and automatically get a list of all the INSERT statements for the data in the table? DdlUtils allows me to create an XML file from a database model but I would like to have it in INSERT statements format and preferably the ability to choose a couple of tables instead of dumping the entire database. Thanks. EDIT: I need it to be a Java API because I want to programatically call it from my Java method.

  • The importance of knowing c++ for web application development

    - by neitony
    I'm a php developer and I want to broaden my knowledge base by learning a higher language (java, c#, c++). My specialty is in building web applications (ria etc). I'm trying to think of the appropriate path to take (hedging my bets so to speak) in terms of which language I should be focusing on. I love open source technology but at the same time C# seems to be getting a lot of notoriety. Despite the newer technologies available there still remains c++ which is the staple for many popular vendors including google and facebook (hip hop) in building scalable and robust cross platform apps. Can anyone offer suggestions as to how I should be looking at this. Should I go Java, C# or C++). They all take time to master and I just want to choose a specialty. Thanks

    As far as I understand, due to license reqirements all web applications, which use MS SQL Server, use SQL Server Express (free) or SQL Server web edition (processor license). Is it so? What are other specific features of SQL Server usage for web app?

  • What ever happened to Java and Sun?

    - by leeand00
    What happened to Java and Sun? The community surrounding them had some of my favorite tools and software to develop with. The Java platform anyway, still looked like it had some promise to it: Groovy and Grails. Why does all of this seem to be going the way of the dodo lately? (Yes, I know their stock price is dropping badly.) Is it just the economy? Or did the lack of cohesion (i.e., not settling on a framework) among the community finally lead to its demise?

  • Get location from where the Java code is executed

    - by drasto
    I have a swing Java application that preserves a lot of data (you can think of a game and its saves for example). Those data are stored in files rather then in database. I would like to keep this files near installation files(.jar file) of my application.Some users(like me) are used to delete default application folder of OS when it comes to large and I don't want them to loose their data this way. Any ideas how to do this easily ? How do I get the folder of the .jar file from program that is executing form that .jar file? Or how do I output files directly into some package? How do I create packages(folders inside jar) dynamically ? Or is there a simple way to distribute Java application in other formats then .jar and then store generated data in installation (sub)folder ? Thanks for reading
