Download J2SE - what's JRE and SDK

Hi
when I want to download the J2S� 1.4.1, I can choose JRE and SDK.
What's what and what's the difference?
RB

If you only want to use Java programs, get the JRE.
If you want to develop Java programs, get the SDK.

  • J2SE download page: JRE and SDK differences

    when we go to the J2SE download page: http://java.sun.com/j2se/1.4.1/download.html#docs, we will see JRE and SDK column. What are the differences??
    My guess is:
    JRE just download the java runtime environment, without downloading the java compiler. JRE means the JVM here?
    SDK downloads everything, including the compiler and run time environment.

    Beginers Question,
    Please describe what is Sun Java JRE and SDK.

    The JRE is the Java Runtime Environment, and is what is needed to run Java programs. It includes the JVM and the standard libraries.
    The SDK is the Software Development Kit, and is what is needed to develop Java programs. It includes the JRE and developer tools such as the compiler.

  • How do I delete terminal from my dock, it won't let me open a download. What is terminal and how did I get it on my dock?

    How do I delete terminal from my dock, it won't let me open a download. What is terminal and how did I get it on my dock?

    Just drag it off the Dock and it will go "poof"
    Look at the Options... when you click on it. Unless it got set to stay there, something you did or an app did caused it to be open.
    Are there any windows open attached to it?
    Is it set to "open on login"?
    I use it but I do not have it or keep it on my Dock. It is found in /Applications/Utilities and installers may need to use it.

  • JRE and SDK Issue

    I installed IBMJava2SDK on my IBM Power PC which has Red Hat Linux on it. I installed it under /usr/downloads/IBMJava2-ppc64-141 directory.
    Later when I check the version by typing and executing "java -version" it shows "Cannot find java"
    So I added the directory in PATH and CLASSPATH but then it give following error:
    bash:/usr/downloads/IBMJava2-ppc64-141/jre/bin/java: No such file or directory
    can anyone help me out on this?

    ls -l /usr/downloads/IBMJava2-ppc64-141/jre/bin/java
    find / -name java 2>/dev/null

  • Hi, would anyone tell me what is the difference between JRE and SDK?

    So which one I should download and install on my computer so that I can do some programming?
    Thanks for help

    JRE is used to run the programs, SDK is the SofwareDevelopmentKit or something like that. So for programming you need the SDK (contains the JRE too). For running the programs you need the JRE.

  • I am having problems with downloading files, what is wrong and what can I do?

    When I try to download a file (ex: file from mediafire) when it gets the windows that lets me choose where to save the file, the window closes and FF automatically downloads the file to a certain place...(last place file was save too)
    == This happened ==
    Not sure how often
    == Not sue...I think it started with the new upgrade...(3.6.6)

    No. There is no other location. Be patient. Read the posts in the Bootcamp Forum. There are hundreds of posts about your issue and what to do. https://discussions.apple.com/community/windows_software/boot_camp

  • Tools and sdk to make java applet for JCOP31 ?

    Dear friend,
    we have a contactless chip card with NXP contactless chip 36 Kb and 72 Kb...
    it has JCOP31 (java card open platform) inside the contactless chip..
    and we have to build the java applet to be inserted into the JCOP31 chip ...
    my questions :
    ========
    1. can we use eclipse to make java applet for this purpose ?
    2. what other tools and SDK do we need to make this Java applet and insert it into the
    JCOP31 chip ?
    3. How can we get the tools ? do you provide it ?
    4. do you know any company that can make this type of java applet for JCOP 31 ?
    5. do you know any company that provide training to make this java applet for jcop31 ?
    Thank you,

    4. Anyone can write you an applet. The specification is open. You could e.g. contact IBM or NXP directly.
    5. NXP offers twice a year a training in Europe and once a yeat in Asia. Contact the customer support at NXP. Also there is a workshop about the 'Art of Java Card Programming' at the smart-university.net (17th Sept., Sophia Antipolis, France). But I think this is for advanced Java Card programmers.

  • Difference between, jre, jdk, sdk and j2se

    Dear Sir/Madam,
    I want to do some java and j2ee development and run these applications in a java application server environment. Can anyone give me some advices on what should i need to download? Moreover, what is the difference between, jre, jdk, sdk and j2se? Should i need to download all of jre, jdk, sdk and j2se?
    thanks and regards,
    david

    JRE is the 'java runtime environment'. It is responsible for creating a Java Virtual Machine to execute Java class files (e.g., run Java programs)
    JDK is the 'java development kit'. It is the same as the 'SDK' (at least in my mind). It normally comes bundled with a JRE and also allows you to compile Java source files into Java class files. The JDK allows you to both write and run programs.
    J2SE is "Java 2 Standard Edition". It can refer to either a JDK or JRE. This is 'core' Java. There is also J2EE "Java 2 Enterprise Edition" which allows you to write middleware or server code more easily.
    Your final choice will be which version. If you want the current, most common implementation:
    J2SE 1.4.2, J2EE 1.3
    If you want to skip ahead to the next generation, the latest releases would be:
    J2SE 1.5 (also called J2SE 5.0) and J2EE 1.4

  • Whats is difference between Java JRE  and  Java SDK

    Hi,
    what is the difference between Java JRE and Java SDK...
    i think both of them have the same set of files to be installed...
    I am not able to understand where they differ

    The JRE (Java runtime Environment) contains just the stuff necessary to run Java and the SDK (System Development Kit) contains the extra stuff necessary (and also helpful) to develop in Java.

  • Trying to download whole JDK & JRE and NOT installation programs

    Hi all,
    I want to download the JRE and JDK in one go and not download an installation program for each one. Ive searched everywhere but surely sun must provide these? Also does anyone know where i can get my hands on a downloadable version of the API docs?
    Many thanks

    Please note that this applies to the currrent java version installed on "standard" windows systems, only.
    To download the current version of Java, go here:
    http://java.sun.com/j2se/1.4.2/download.html
    and click on the word DOWNLOAD in the column labeled SDK in this line: Windows Offline installation (info)
    The API documentation can be downloaded from this same page, just scroll down...
    After downloading, click on this page of installation instructions and read through #6:
    http://java.sun.com/j2se/1.4.2/install-windows.html
    Install the software according to the preceeding instructions. During the installation process, you will be asked if you want to install a public JRE. Answer YES, this is the separate JRE that gets installed in C:\Program Files\Java\j2re1.4.2_01.
    If you encounter problems, see the section "Troubleshooting the Installation" in the installation instructions.
