Do I need Java 8 or should I disable it? What happens if i disable it? And what is the difference between Java and Java Runtime?

There's no difference. They're both runtime plug-ins (they run when an app calls for Java functions).
You only need Java if you either have Java apps on your Mac that won't run without having it installed, or you use trusted web sites that require Java to function (getting fewer and far between). Otherwise, you have no need for it at all.

  • What's the difference between Java SDK and the Enterprise Edition?

    What's the difference between Java SDK and the Enterprise Edition? Are they both free?

    both r free but they are used in diffrent applications. sdk are used for simple apps that run on your computer while j2e (enterprise edition) are ment for large distributed computer systems that include servers and such. if you don't know the diffrence you probably wont need the the j2e, only the sdk.

  • What's the difference between "overloading" and "overriding" in Java

    What's the difference between "overloading" and "overriding" in Java

    hashdata wrote:
    What is the real-time usage of these concepts...?Overriding is used when two classes react differently to the same method call. A good example is toString(). For Object it just returns the class name and the identityHashCode, for String it returns the String itself and for a List it (usually) returns a String representation of the content of the list.
    Overloading is used when similar functionality is provided for different arguments. A good example is [Arrays.sort()|http://java.sun.com/javase/6/docs/api/java/util/Arrays.html#sort(byte%5B%5D)]: all the sort() methods do the same thing (they sort arrays), but one sorts byte-arrays, another one sorts int-arrays, yet another one sorts Object-arrays.
    By the way, you almost certainly mean "real-world" usage. "real-time" (and thus "real-time usage) means something entirely unrelated to your question.

  • What is the difference between action and workflow? How do I decide that I need an action in a transaction and not a workflow and vice versa?

    Dear Experts,
    I have few doubts and request your expert inputs to clarify my doubts.
    What is the difference between action and workflow? How do I decide that I need an action in a transaction and not a workflow and vice versa?
    Your earliest response is highly appreciated.
    Thanks,
    SMTP

    Hi SMTP,
    First of all, as I mentioned action is nothing but an executable work item which is designed in the workflow itself. In other words, Workflow is like your OOPS class. At run time, workflow instances are created just like objects of classes. Now, the steps designed in the workflow are called TASKS and the instances of tasks are called WORKITEMS. Now, the work items where any user action is required are called executable work items. ANd the work items where no user action is required (for example, sending an email in background) are called non-executable work items.
    Whether to go with development of workflow or not depends upon your business scenario. If your requirement is only to send an email and you find any BAdi or exit where in you can write your logic then there is no need of creating a workflow. If there is a defined business process with defined users and time lines, then you can go with the development of workflows.
    Rest, the below link will help you in understanding basic concepts of workflow :

  • Java-options, What is the difference between the parameters xms and ms

    Hi,
    I have a problem with deploy bpel process , I get an error "java.lang.OutOfMemoryError: PermGen Space" several sources of information tells me that I have to change some parameters in the file "<ORACLE_HOME> / opmn / conf / opmn.xml" but I doubt some of the parameters, what is the difference between Xms and ms?
    And what is the value of the parameter MaxPermSize, which I must also change.
    Thanks
    Gustavo

    Did you ever find out what the difference between the two parameters were!? I have the same questions. Default for opmn.xml = "-server -XX:MaxPermSize=128M -ms512M -mx1024M ...." In attempting to maximize performance and accessible memory, Oracle docs identify adding/modifying "-server -Xmn1228m -XX:+AggressiveHeap -Xms2048m -Xmx2048m -XX:MaxPermSize=128M -ms2048M -mx2048M...." But I question if Xms and ms are really the same parameter or not?
    Thanks in advance...

  • What is the difference between saving to "Documents" and "Macintosh HD" and when should you use each one?*

    What is the difference between saving to "Documents" and "Macintosh HD" and when should you use each one?

    When you save to the folder with the little house icon, the file is placed at
    /Users/your_user_name/
    You would really have to go out of my way to save at:
    (the shortcut for the Boot Drive, regardless of its name).
    I am not sure how you decided that Time Machine is not saving your files. The default is for Time Machine to do incremental Backups of everything on all attached drives, except for certain temporary information in Cache files. If you have four Users, Time Machine will back them all up.
    Looking at the raw Time Machine backups will tell you very little, because it does lots of its work with Hard Links, and because it does incremental backups, so only files that changed since the last Backup are saved at thet cycle. The way to determine whether Time Machine is saving things is to display the window you care about in the Finder, then invoke the "Star wars"/ "Back, back, back in time" Interface.

  • What is the difference between java direct or java bean in JSP?

    What is the difference if I use java code directly in JSP or use java bean in JSP?
    Which class to use for receiving the passed parameter from html or java script? Any difference for java code and java bean in the way receiving the passed data?
    How can I pass string from jsp to html or java script?

    it's generally accepted as better design to separate presentation from logic. meaning, the java code in the jsp should be used to support displaying data, as oppsoed to implementing the application - like database access, etc.
    when the logic is separated from the presentation, it allows you to reuse logic components within several jsp pages.
    if you decide to change the presentation layer in the future (to support wap, for example) you don't need to rewrite your entire application, since the "guts" of the application is outside of the jsps.
    it is also a good idea to separate your business logic from your data layer. adding a "buffer zone" between these layers helps in the same manner as in separating presentation from logic. if you're using flat files for storage now, upgrading to a database wouldn't require rewriting all your business logic, just the methods which write out the data to a file, for example.
    once you feel comfortable with separating the various layers, check out the struts framework at http://jakarta.apache.org/
    to answer your second question, to get parameters passed in from HTML forms, use ServletRequet's getParameter() method.
    in tomcat:
    <% String lastName = request.getParameter( "lastname" ); %>
    to answer your third question: when displaying the HTML from withing a jsp, print out the string to a javascript variable or a hidden form element:
    <% String firstName = "mike"; %>
    <input type="hidden" name="firstname" value="<%= firstName %>">
    <script language="javascript1.2">
    var firstName = "<%= firstName %>";
    </script>
    this jsp results in the following html:
    <input type="hidden" name="firstname" value="mike">
    <script language="javascript1.2">
    var firstName = "mike";
    </script>

  • What is the difference between the three network carriers and  if i am to use iPhone 5 in Bangladesh, which network carrier should i choose?

    I had one confusion about the network carrier of which one to chose. Actually I do not know the difference between them. Are they related to some sort of sim cards? I would be grateful if anyone could help me to get away this confusion.

    Unless we are in Bangladesh, nobody here can really help you with this.  If you purchased the phone there, you need to do that research for yourself.  You are the one who is there and on the spot so noone else can really help you with that.
    You need to contact the available carriers in your area and see what the differences are for yourself.
    The phone companies supply you with the appropriate sim cards when you take out a contract with them.
    Also, where did you purchase the phone from in the first place and is it an unlocked phone?  If the phone is not unlocked, then it won't work.

  • What is the difference between knowing J2EE and knowing Java?

    Okay, I need a little help and guidance. I've been doing integration work for the past couple of years and I've been creating small programs in Java with our EAI application. Basic database updates, reading different file types from disc (XML, fixed-length, etc.), and a lot of other things. But never full-blown applications. So I think I know the Java language pretty well, although I haven't used everything, just what I needed.
    I've been hearing this phrase getting thrown around a lot: "Do you know J2EE" instead of "Do you know Java". What is the actual difference between the two? (Any good websites or books would help a lot).
    Another question I had since we were always building small programs they was never a great deal of stress to build object-oriented code. Is there a good book and/or websites on some basic standards and rules of thumbs to think about when I start designing my code?
    Thanks everyone

    Think of all the rich programs you can write with no import statements. That's knowing Java the language. Start adding the packages in the SDK. Ok, now maybe that's enough Java to get a job. J2EE adds a lot more packages for a bunch of interesting things - JSP and Servelets, EJB containers, etc. Sun docs on J2EE ought to list out all the wonderful added features. I'm sure I don't know anyone who has mastered ALL of these packages - "knowing" J2EE might take a direct download from the Matrix. Many interesting programs get along fine without any J2EE features.

    Java is a programming language, Javascript is more for web pages. It is used to add interactivity to your web pages. 2 different languages.

  • What're the differences between JSP, Java Script, and Java Applet?

    I am confused by the concepts: JSP (Java Server Page), Java Script, and Java Applet? What are their main differences?

    I don't know about differences, but one of their main similarities is that each of them has a page in Wikipedia.
    JSP
    JavaScript
    [Java applet|http://en.wikipedia.org/wiki/Java_applet]
    There. That should give you enough information.

  • What's the difference between Java SE 6 Update 10 RC and JDK 6 Update 7

    I want to download jdk and do some java development. But I saw "Java SE 6 Update 10 RC" and "JDK 6 Update 7" are both there for me to download. I don't know which one should I download. I used to think JDK is Java SE. Can someone explain it to me? Great thanks!

    [Java 6 Update 10|http://java.sun.com/developer/technicalArticles/javase/java6u10/] provides some nice enhancements for deploying Java to the Desktop, a nice new look and feel and some other nice additions.
    Also, JDK 6 Update 7 is the latest, officially released version at the moment. The Update 10 is only a release candidate (that means it is what might become the final Update 10, but can still change).
    For normal development (and especially when you're just starting to learn) there shouldn't be too much difference, so choose whichever you want.

  • What's the difference between the java and javaw?

    As the title
    Thanks

    If you start java code with java.exe, closing the DOS command line window will close the Java application. If you start it with javaw.exe, it will not, but with javaw.exe you have no standard out, meaning printing with System.out.println() will not show up anywhere, because the JVM discards the standard out. If you start a Java application from within Windows directly (Using Start -> Run for example), starting it with java.exe will open a DOS box for the application, starting it with javaw.exe will open no DOS box at all (it will start like a Windows application). As should be clear now, it makes only sense to start Java applications with javaw.exe that have a GUI (graphical user interface), as otehrwise they won't be able to communicate with the user.
