JDK and SDK

Greetings!
im new...
What's the difference between the two(jdk and sdk)?
I remember downloading JDK(and JCreator[editor]) only(no J2SE or watsoever) to create simple programs. Well, I managed to create HelloWorld and all but does this mean I dont need j2se or j2ee to create programs?
Also are JDKs and SDKs inside J2SE, J2EE ... bundle?
pardon me, but im just really 'new to java technology' :D

J2ME - a subset of J2SE for "mobile devices", this comes in different "profiles", which build on the basic subset to add mobile-type extras (for example: a Graphics toolkit for small LCD-based screens).
J2SE - "Standard Edition", the basic, primarly "desktop" aimmed edition. Learn first
S2EE - Enterprise Edition, builds on J2SE to add "Enterprise" (server) extras (for example: web servery stuff)
JVM - The Java Virtual Machine, a sort of "emulator" for Java programs
JRE - Java Runtime Envroment
JDK - Java Development Kit
SDK - Software Developement Kit

    what are the differences between jdk and sdk?? thanks

    Just marketing whims.
    SDK = software development kit
    JDK = Java development kti
    Sun has use both names to refer to its SDK for Java. I forget which one they're using now, but they've switched a couple of times.

  • Confused between JDK and SDK

    Hello, everyone,
    I am really confused about JDK and SDK. I have tried to find something online which can make it clear. But unfortunately, I am still confused on their relationship? It seems that they are the same thing?
    Thank you for any help.

    Hi there,
    If I'm not mistaken, JDK no longer exists.It used to be the same thing as JSDK nowadays. It's just a matter of names, and shouldn't worry you.
    See you !

  • Difference betweeb JRockit JDK and SDK?

    Can somebody enlighten me the diff. above.
    Can the SDK be used together with the JBuilder SDK or Netbeans SDK?
    Thanks
    Francis

    Hi Francis,
    There is no difference between JDK and SDK in this context. SDK was used by Sun up to and including Java 1.4.2 to denominate the package consisting of the Java runtime (i.e. the JVM and the native libraries) and the developer tools (javac etc). They later switched to using JDK instead. JRockit follows the same convention.
    JRockit should work fine with any Java application, including IDEs like JBuilder or Netbeans. In the unlikely event that you run into problems, please contact us through the JRockit user forums here:

  • What's the difference btw JDK and SDK?

    I went to the download page,some of the download are for J2SE Development Kit (JDK) ,some others are J2SE Software Development
    Kit (SDK)?Are there any difference btw them?

    Sun changed the label from SDK to JDK when Java 5 was
    released.There was at least one earlier change, I believe, so it seems it was JDK, then became SDK (or J2SDK) and now back to JDK.
    In the context of Java, if you're not a purist about matching a particular acronym with a particular version, then the two are interchangeable.

  • What are the differences between api and sdk

    Hi,
    Could anybody clarify for me what are the difference between API and SDK? I googled for the answer, and couldn't find any thing on this topic.
    Many thanks in advance.

    Is it correct to say that "a SDK includes all the
    APIs"? or "API sits on top of the SDK"?It's a bit weird to say either. First, the JDK doesn't include all APIs. Just the J2SE core API. Others, like 3rd party libraries or J2EE are not included. Second, if you mean the API docs, they're also not included IIRC.
    It'd technically only be correct to say "the SDK provides an API", I guess. The example is very lame, but: if the SDK is a machine, the API is the sum of its buttons and levers and gauges and intakes and outlets and exhausts. The API docs are the manual.

  • Install jDK and  Tomcat on Solaris64

    1. hi all, before I always run JDK and tomcat on Win ,righ now I want to try them on Solaris64, I just wonder do I need to set path and classpath ? where and how to set it?
    2.on asp.net we can use free toollike WinMerge to comapre which part of code be change, in java or jsp , is there any this kind of free compare tool.
    thank you

    If you drop the /bin portion it should work. JAVA_HOME is the directory that the SDK installed in.

  • Difference between JDK and J2SDK ?

    Hi
    I am a novoice in Java. Please tell me the diff between JDK AND J2SDK ?

    Hi
    I am a novoice in Java. Please tell me the diff
    between JDK AND J2SDK ?They are about the same. Sun likes to change the name
    from time to time. The SDK might contain Netbeans as
    well.
    KajActually, they are exactly the same. You can download a bundle that contains the JDK and Netbeans, but I wouldn't consider Netbeans to be part of the JDK.
    Sun has been pretty bad about naming things for years. While they are not exactly the same thing, SunOS 5.8, Solaris 2.8, and Solaris 8 all basically mean the same thing.
    The J2SDK/JDK distinction is just one of those lingo things that you pick up on at some point.

  • What is the difference between jdk and jsdk

    I don't know the difference between jdk and jsdk,if i had set up the jdk,could i develope the servlet.

    For servlets you need J2EE classes, which are in what is usually called JSDK (Java Server Development Kit). So, you cannot compile servlets with just the JDK installed, you need to download the J2EE SDK.

  • JDK or SDK ?

    whats the diffrence between a JDK and a SDK, and whick jdk or sdk version is the best (in your humble opinion ) for newbies?

    They're the same thing. JDK stands for Java Development Kit and SDK stands for Software Development Kit. People generally refer to the "Java SDK" or the "JDK". Same thing. The JRE, on the other hand, is simply the Java Runtime Environment and provides no development tools.

  • 12/03/2013 - Beta - AIR 4.0.1240 Runtime and SDK

    Adobe AIR Beta Channel Update
    This beta release provides access to the latest AIR runtime and SDK (with compiler) for Windows, Mac OS, iOS and Android.
    With this release, we are introducing a new numbering scheme for our product versions. Adopting the pattern set by Google with Chrome and Mozilla with Firefox, we will simply update the major version number with each subsequent release. In other words, beginning with the release of "Jones", Flash Player will become Flash Player 12. With each new major release, roughly every 3 months, that number will increase by one.
    This change will also apply to AIR and the AIR SDK, albeit not right away. Our "Jones" release will be numbered AIR 4 and AIR SDK 4; however, with our "King" (Q2 2014) release, the version number will be synchronized with the Flash Player version at 13.
    Below are some of the key features and benefits of AIR 4.0.  Please see our release notes for full details.
    New Features:
    iOS - Improved Packaging Engine
    We're very excited about this new feature.  The new packaging engine we're working on can improve iOS packaging time up to 10 times over the current packager!  However this feature is still early in development and we'd like to get your feedback.  To enable this feature, please use "-useLegacyAOT no" in the ADT command, before the signing options.
    Graphics: Buffer Usage flag for Stage3D
    We've added a new enum Class called Context3DBufferUsage which defines two constants, STATIC_DRAW (default) and DYNAMIC_DRAW.  These constants specify how buffers will be used in Stage3D. We've also added a new parameter, called "bufferUsage", to the constructors of VertexBuffer and IndexBuffer. This "bufferUsage" parameter uses one of the constants form Context3DBufferUsage, which will allow you to select the appropriate buffer type according to your needs.
    Android Workers
    Introduced as a beta feature in AIR 3.9, we're continuing to improve this feature based on your feedback in preparation for an official release in AIR 4.
    Android - Support for native resources access by R* mechanism in native extension
    Currently, to use the native Android resources in the Android Native Extension one has to use getResourceID() API while typically to access the resource IDs developers use the R.* mechanism. AIR 4.0 onwards, apps developers will be able to access the resources by R.* mechanism. All the dependencies need to be specified in platform.xml as following and all the dependencies and resources to be packaged in the ANE.
    Supplementary Characters Enhancement Support for TextField – EXTENDED BETA
    This is a desktop enhancement for supporting surrogate pairs in the TextField control.  Now, characters out of the Basic Multilingual Plane(BMP) with Unicode code points between U+10000 and U+10FFFF will work correctly in the TextField control.  It greatly enlarges the code point range we support and includes characters like emotion symbols (emoticons) and complex CCJK characters.  This feature is being introduced in the AIR 4 beta but will go live in a subsequent release.  Due to the sensitive nature of text display, we would like an extended test period to ensure no bugs are introduced.
    Stage3D Creation of Context3D with Profile Array
    We've added a new interface to Stage3D.requestContext3DMatchingProfiles(profiles:Vector.<String> ) which will create a Context3D with highest level suitable profile that is in profile array, based on the current hardware.  A developer can check the newly added property 'profile' to obtain the current profile that was chosen by the Flash Runtime.
    Support for Android 4.4 (KitKat)
    We've completed our support testing with AIR against the latest Android 4.4 release.  Please let us know if you encounter any problems.
    Known Issues:
    Timeline animation does not play properly in Air 3.9. [3647538]
    Hunger Games Adventures become unplayable after 10 min on iOS7 [3651083]
    Text field stops updating on iOS 7 after giving voice input. [3658462]

    Ok, just figured this out. The cert I created was somehow malformed. I simply created a new one with the Flash IDE which worked fine. Any other method of creating the cert that I tried failed, including the keytool command line utility.

  • 8/20/2014 - Beta - AIR 15.0.0.233 Runtime and SDK

    Adobe AIR Beta Channel Update
    This beta release provides access to the latest AIR runtime and SDK (with compiler) for Windows, Mac OS, iOS and Android.  You can download the AIR beta here: Download Adobe AIR 15 Beta - Adobe Labs
    Below are some of the key features and benefits of AIR 15. Please see our release notes for full details.
    New Features:
    Stage3D “Standard” profile support for iOS and Android
    In the Flash Runtime 14 release we introduced the Stage3D “Standard” profile which provided many advanced 3D features.  At that time, the “Standard” profile was only available on desktop platforms.  In the AIR 15 release we are extending this coverage to mobile platforms.  If a device supports OpenGL ES3, it can successfully request the “Standard” profile and use the same advanced features as the desktop platform.
    Relaxing Stage3D Render Target Clear
    In previous versions of Stage3D, after switching the render texture through Context3D::setRenderToTexture, you were required to clear it before drawing. In this release, we're removing this limitation and optimizing the use of render textures. This change will allow you to further optimize and reuse depth and stencil buffers between different render textures.
    StageText.drawViewPortToBitmapData now supports Retina displays
    Currently, AIR will allow a bitmap with the same width/height of the StageText object to be passed into drawViewPortToBitmapData.  While fine for standard resolution displays, this is not sufficient for Apple's Retina HiDPI displays.  Based on customer feedback, we've altered the drawViewPortToBitmapData method to accept a doubled size BitmapData with StageText's view port on a Mac Retina display, and then draw a HiDPI image from the view port.
    Improved Packaging Engine is now default - iOS
    Starting AIR 15, new improved IPA packaging engine is now the default packaging mode when packaging for AOT targets ipa-app-store, ipa-test, ipa-ad-hoc and ipa-debug. If you encounter any packaging or runtime issues, please report at http://bugbase.adobe.com. To use older packaging mode, use "-useLegacyAOT yes" in the ADT command, before the signing options. To learn more about the feature, please follow http://www.adobe.com/devnet/air/articles/ios-packaging-compiled-mode.html
    AIR Gamepad Enhancements
    AIR Gamepad feature enables the app developers to provide a second screen on Android mobile devices for the Flash based browser games. AIR Gamepad API enables Flash based browser apps to connect to a paired Android device running the AIR Runtime app and therefore allowing the Android devices to be used as game controllers or second-screen interfaces. Following enhancements are available starting AIR 15.
    Multiplayer Support
    Gyroscope Events
    Magnetometer Events
    Applying skin as AIR gamepad screen
    To learn more about the feature and usage guidelines, please follow www.adobe.com/devnet/air/articles/android-air-devices-as-gamepads.html
    AIR Cross Promotion
    Adobe AIR 15 now supports cross promotion of AIR games for mobile devices. Cross promotions can be effective in saving some amount of advertising cost. With the right partnership, you gain access to a wider customer base with a demographic similar to that of your application. This cross promotion is free and works on a credit system. All you need is to earn enough credit points by promoting other AIR games to begin your own promotion campaign. The AIR SDK offers the new AdViewer API for promotion campaigns as a SWC, it provides functions to load and show in-game advertisements. You earn credit points for promoting AIR games by other developers based on ad impressions and clicks. To learn more about the feature and usage guidelines, please follow www.adobe.com/devnet/air/articles/cross-promotion-of-air-games-mobile.html

    I've settled on the following workaround, which fixes the problem consistently, albeit with a slight flicker sometimes:
    Check if you're on Android;
    Add an ENTER_FRAME listener to the stage in the activation handler (called when returning to the app from an overlay displayed by a native extension);
    Use a ticker to have 2 frames delay between the quality switch, anything quicker than that resulted in inconsistent or non-functional behavior for our app;
    Switch from StageQuality.LOW to StageQuality.HIGH and back again. Going to MEDIUM and back did *not* result in a fix.
    In my case, the code for the switch itself looks like this:
    private function OnActivate(event:Event):void
         if (Settings.IS_ANDROID)
              _Ticker = 0;
              stage.addEventListener(Event.ENTER_FRAME, OnEnterFrameFixGPUContextLoss);
    private function OnEnterFrameFixGPUContextLoss(event:Event):void
         _Ticker ++;
         if (stage.quality.toLowerCase() == StageQuality.LOW) // stage.quality returns string in capitals
              stage.quality = StageQuality.HIGH;
         else
              if (_Ticker > 2)
                   stage.quality = StageQuality.LOW;
                   stage.removeEventListener(Event.ENTER_FRAME, OnEnterFrameFixGPUContextLoss);
