Difference between JRE or J2SE

If anyone knows the difference please reply!!!! I need to dowload latest java runtime environment for JCreator program!!!

JRE is a barebones install containing just the libraries required to run a Java program... J2SE contains the JRE plus programs to build/develop Java programs... J2EE contains J2SE plus programs to run a web server, host Java applications, and a variety of enterprise server related functions.

  • 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

  • Differences between GUI in j2se and cdc+pp

    hello guys and girls,
    is there many differences between the GUI in j2se and cdc+pp? I only know that cdc+pp does not support swing. anyone who has such experience in my question, please give me a hand. thanks!

    Hi,
    What I know about it is that PP implements j2se 1.3 AWT components, and, as for all classes, without deprecated methods.
    There is not too much secret about it. I work on a project for Pocket PCs and all the screens I've designed on NetBeans, with it's Form Editor, and then copied and paste the generated code into my project, which I develop using Websphsere Studio Device Developer.
    Unfortunately NetBeans Mobility Pack doesn't implement CDC/PP, only CLDC/MIDP.
    I hope it can help you a little.

  • Date difference between j2mewtk and j2se

    In j2mewtk, I have
    DateField aDateField = new DateField("Date", DateField.DATE);
    // ...I pick March 27, 2002 on the UI for aDateField
    long j2meLongDate = aDateField.getTime();
    then I pass j2meLongDate to a server side program, which is running in j2se environment, and I do
    Date date = new Date(j2meLongDate);
    System.out.println(date);
    // print out March 26, 2002 !!!!
    Can somebody tell me why and how to solve the problem?
    Thanks,
    -John

    I think you have a problem with the timezones; there are different in both sides.
    Try to set them with the system property user.timezone. You can do it either inside the code (System.setProperty("user.timezone") )or in the command line (-Duser.timezone=...)

  • 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.

  • Stupid Question: ... difference between JRE and SDK ?

    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.

  • What is the difference between JRE,JVM and JDK?

    plz reply me to the following question
    (1)what is JRE,JVM and JDK?

    The JRE is a java distribution for running java programs. It does not contain the development tools needed to compile and debug java programs.
    The JDK is a java distribution for both running and developing java programs. In includes the deveopment tools.
    The JVM is part of both the JDK and the JRE. It is the 'engine' that executes java bytecodes, performs garbage collection and does just-in-time compilation.

  • Differnce between jre and container

    This may be a silly question, but i want to know what is the difference between jre and a container?

    gtkrish wrote:
    yes i am specifying about containers like sevlet container , it also does the job of executing code,right?No. The JVM is executing the code (insofar as the JVM ever actually executes anything). The container simply manages some of that code for you, and provides services to your code, such as JNDI

  • 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.

  • 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.
