  • Difference between JDK , JRE J2EE

    Hi
    Would anybody just show the difference between JDK , JRE , J2EE , and J2RE
    Thanks alot

    JDK - Java SDK from Sun
    JRE - Java Runtime Environment
    J2EE - Java 2 Enterprise Edition
    Basically, JDK is J2SE, Java Standard Edition. You need this to develop and to compile standard Java software. JRE allows only execution without any special components. J2EE is extension to J2SE. It contains Business or Enterprise components like Java Beans.

    This is a weird question. But I really need to know
    the difference between jdk vesion 1.3.1-b24 and
    1.3.1_02-b02.Bug fixes only.
    When reading the strings above, ignore the part saying "-b##" (that's the build number). So you're looking at 1.3.1 (the base release), and 1.3.1_02 (patch 02 on 1.3.1).

    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.

    A JDK is a set of tools for Java development including compiler, runtime system and standard libraries. J2EE is the enterprise version of the Java technology platform (it's one of three). To use it you download the proper JDK's.

  • 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.

    what is the difference between jdk and jre
    plzz tell me in detail

    It's an extremely important skill to learn how to search the web. Not only will it increase your research and development talents, it will also save you from asking questions that have already been answered numerous times before. By doing a little research before you ask a question, you'll show that you're willing to work and learn without needing to have your hand held the entire time; a quality that is seemingly rare but much appreciated by the volunteers who are willing to help you.
    If you've done the research, found nothing useful, and decide to post your question, it's a great idea to tell us that you've already searched (and what methodologies you used to do your research). That way, we don't refer you back to something you've already seen.
    To get you started, here is an excellent resource: The Java� Glossary

  • Whatz the difference between jdk and jre

    i would like to know the difference between jdk and jre.

    Yes JRE is Java Run Time Environment. The java programming language adds the portability by converting the source code to byte code version which can be interpreted by the JRE and gets converted to the platform specific executable ones. Thus for different platforms one has corresponding implementation of JRE. But JRE has to meet the specification JVM (Java Virtual Machine) Concept that serves as a link between the Java libraries and the platform specific implementation of JRE. Thus JVM helps in the abstraction of inner implementation from the programmers who make use of libraries for their programmes.
    The JDK(Java Developmental Tool kit) comes along with java libraries and JVM embedded in it. Apart from these it comes along with the utility tools for byte code compilation "javac", Executing the byte codes through java programmes through "java" and many more utilities found in the binary directory of java. Speaking practically JDK is essential for developers, which comes along with library packages to develop Software programmes. While JRE is minimal set of programmes which executes the java class files developed by the software developers.

  • DIFFERENCE BETWEEN JDK 1.3,1.4,1.5 and 1.6

    Can anybody give clear differences between JDK 1.3,1.4,1.5 and 1.6.

    You would do well to stop and reflect on the fact that with hundreds, if not thousands, of changes implemented over the years covered by your request, a more specific question will recieve more specific replies.
    Had you mentioned having read the release notes, I would not have bothered mentioning them. But they are the standard source for this information. And they (and the documents they link to) are quite comprehensive: allowing you to choose which of the changes you consider most important based on whatever criteria you are using.
    But, since you have read them: cite and ask about what you can't understand.
    Or stick around and someone will post a link to a site with a 50 word summary you can copy, paste, submit and forget.

  • Difference between JDK/JRE

    Guys,
    I need to know the difference between JDK and JRE? When should one use JDK and when one should use JRE. What is the advantages/disadvantages of using one over other.
    Cheers,

    Shutt up guys... one person is to know some thing about JDK/JRE, and you.....
    Any way
    Hi tnischal!
    Your question was about JDK/JRE
    JDK = Java Development Kit
    JRE = Java Runtime Environment
    JRE is a comolete Setup of J2sdk1.4.1(LatestVersion of JDK(1.4.1) with other requirements to use this version included JDK1.4.1,JavaWebStart,SunJVM,Java2PlatForm, and all other needs for it.
    while JDK is only the Software Development Kit. Previous versions of JDK than V1.4.1 did not need the all Runtime Environment for JDK, You just copy the JDK Folder in your machine and use it
    But you can't use JDK1.4.1(fully) without other requirements of use it.
    Hope you got the difference now.

  • The difference between AIR-ANT5135D-R and AIR-ANT5135DB-R

    Hi,
    Anyone know what is the difference between AIR-ANT5135D-R and  AIR-ANT5135DB-R ?
    From the dynamic configuration tools for 1252 and 1242, AIR-ANT2422DB-R is inside one of the antenna option.
    However, I can't find it in the "Cisco Aironet Antennas and Accessories Reference  Guide"
    http://www.cisco.com/en/US/prod/collateral/wireless/ps7183/ps469/product_data_sheet09186a008008883b.html
    Inside the document there is only AIR-ANT5135D-R.
    likewise for the 2.4 GHz,  AIR-ANT2422DB-R is inside the dynamic configuration tools and not inside "Cisco Aironet Antennas and Accessories Reference  Guide"
    Any help would be appreciated
    Thanks,
    Richard

    Found the difference, AIR-ANT5135DB-R and       AIR-ANT2422DB-R are  non-articulating antennas.
    Thanks!
