  1. How can I improve this java code?

    mldaalder said you 'may' consider using classes. I would say, you definitely should use classes, even though it might be confusing for a beginner. You also might have a look at the neat tool FindBugs (http://findbugs.sourceforge.net/) which tries to find pitfalls in your java code and points out where problems might occur or simply where you use constructs which are considered to be bad practice.
  2. For the case you didn't solve the problem yet, have a look at http://www.coreservlets.com/Apache-Tomcat-Tutorial/index.html#Java-Home
  3. Source for project??

    Don't know, if it fits your needs but have you had a look at http://stratagus.sourceforge.net/ ?
  4. As far as I know it's not possible.
  5. Starting Assembly Programming

    For Win32Asm you should definitely have a look at Iczelions tutorials: http://win32assembly.online.fr/tutorials.html And as an alternative to the MASM32 package (which is pretty good) you might have a look at NASM32: http://quasar.astalavista.ms/nasm32.html
  6. JOGL Lesson 09 NeHE

    You have to open the JAR-file with an extractor application like Winzip or Rar. Inside is another JAR-file which you have to open again with the extraction-application. Inside of the second JAR is the source.
  7. Delphi help. Need to get started.!

    I've never saw a good (beginner) tutorial about Delphi on the web. I'd recommend to buy a book to get the basics.
  8. Netbeans Help(java IDE)

    Have you tried to run the ant task 'clean' before building? Or running the task 'all' instead of 'compile', which should make a complete build of your application.
  9. Do they ever?

    3D Realms released the sources of Duke Nukem 3D, Rise of the Triad and Shadow Warrior under http://www.3drealms.com/downloads.html
  10. Usually I avoid answering questions which imply a "vs." but for J2ME developing I definitely prefer Netbeans over Eclipse. I've used Eclipse for 5 months at work but changed back to Netbeans because the Mobility Pack of Netbeans was much (!) better than the Eclipse plugin. Ok, I have to say, that I stopped using Eclipse in May but I cannot imagine that they improved the plugin that much that it could beat the Mobility Pack today. But as usually: give both a try and decide on your own. As resources: http://www.forum.nokia.com/ http://developer.motorola.com/ http://java.sun.com/javame/index.jsp
  11. Java Explanation?...

    Have you already had a look at the documentation? The Java-API is quite good documented: http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Object.html
  12. Mobile phone development

    First link (NetBeans IDE, Mobility Pack and Profiler 5.0 downloads) and there you need "NetBeans IDE 5.0 Installer" and "NetBeans Mobility Pack 5.0 Installer". That's all. (assuming you installed already a java sdk).
  13. Mobile phone development

    You can use Eclipse but for mobile development Netbeans (and its Mobility Pack) is (at the moment) much better than Eclipse.
  14. Mobile phone development

    You could start here: http://java.sun.com/javame/index.jsp
  15. Quote:Original post by someboddy 1) I read in the EclipseME docs that in order to use the javadocs, I need to select each javadoc directories in the libraries configuration of the devices at "Device Management". However, I have no idea with javadoc directory goes for each device(Or maybe I need to set a different one for each jar file?). Can anyone give me a clue? Good luck. I worked for three months with Eclipse and I was not able to figure out, how to solve this problem. For J2ME development Netbeans MobilityPack is way better than Eclipse. Quote:Original post by someboddy 2) What does each device stands for? I guess they are different types cellphones, But which is which? My current guess tells me that: DefaultColorPhone is for cellphones who support color. DefaultGrayPhone is for older monochrome cellphones. QwertyDevice is for orginizer like cellphones with actual keyboard. And I think MediaControlSkin is either for testing purposes(which makes no sense, but that's what the name suggests), or for third generation cellphones. Am I right? Hm, I don't know, never thought about it. I'm just using the DefaultColorPhone for prototype testing and the emulators of the different vendors (Nokia, Motorola, Sony Ericson, Siemens/BenQ) which can be downloaded for free on the vendors websites. Quote:Original post by someboddy 3) Can a newer cellphone use a MIDlet compiled for an older cell phone? You have to consider the MIDP and CLDC versions. If they are equal (or newer) it is supposed that your MIDlet runs on the other device. But keep in mind that other devices have different resolutions, different amount of memory and different processors. If you want to be sure your MIDlet runs on a specific mobile phone, you have to test it on the real device. Quote:Original post by someboddy 4) Can I safely assume that a MIDlet who works on the emulator will work on an actual cellphone? No! Sometimes it even happens, that it's not working in the emulator but on the real device. Quote:Original post by someboddy 5) Does the emulator limit the memory and the cycles per seconds of the MIDlet to mimic a realcell phone? Depending on the emulator. The emulators from Motorola are quite good because the emualtors are just an image of the firmware from the real device. But still it's not granted that your application also works on the real device. Usually MIDlets runs a bit faster in the emulator.
