Hi,all i think it seems to be silly question about markable interface

i know that markable interface doesnt consists any methods.But when we implements those interfaces how they behave to service the class.
ex.
public class MyClass implements java.io.Serializable
MyClass is serializable but the java.io.Serializable doesnt consist any methods how it service to MyClass

you implement the Serializable interface just to let the API/JVM to know that the instances of the class can be serialized.
These kind of interfaces are called marker interfaces.
By the way some time ago there was a good discussion on marker interfaces on this forums. Try searching you might find it.

  • This may seem like a silly question but I need it answered plz

    This may seem like a silly question but I am pretty new to
    dreamweaver but I am learning it. The question I have is this. When
    your typing a paragraph and hit enter to make the next line of text
    it goes down 2 spaces. Sometimes I don't want those two spaces. I
    want no space between the two sentences. How do you put one
    sentence below another with no spaces? Thanks in advance. I seems
    to have figured out all the other basic stuff except for this one
    thing lol. Thanks for the help in advance.

    You can get the latest jQuery Mobile Themes directly from jQuery Mobile's web site.

    Hi All,Is it possible to write custom markable interface
    Thanks in advance

    Here is a basic exmaple.
    interface ExampleInterface {}
    class ExampleInterfaceImpl implements
    ExampleInterface {
         private boolean doSomething = false;
         public void setDoSomething(boolean doSomething) {
              this.doSomething = doSomething;
         public void doIt() {
              if(doSomething)
              System.out.println("Look! I am doing it!");
    public class Example {
         public static void main(String[] args) {
    ExampleInterfaceImpl exImpl = new
    ew ExampleInterfaceImpl();
              if(exImpl instanceof ExampleInterface) {
                   exImpl.setDoSomething(true);
              exImpl.doIt();
    }Hello George,
    So where is the check performed for say the
    Serializable Interface? that says if Serializable
    then it can be Serialized?
    CheersNot in the JVM

  • Hi All! Found this community and have a question about Hyperlinking docs

    I have eDocs DM 5.3.1 and some of my users are getting broken hyperlinks in pleading indices being created in the Records department.
    We noticed that if we purge the DM cache, shut down the DM process and then restart windows explorer, it fixes the hyperlink.
    Anyone have a clue or two I could investigate to find a fix?

  • Might seem like a silly question but why don't pages automatically load when I type the URL in?

    Sometimes they immediately open other times I have to hit enter for it to load. Why does this happen?

    That issue can be caused by an extension that isn't working properly.
    Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
    *Don't make any changes on the Safe mode start window.

  • When I want to randomly play (shuffle) all my songs, it seems that the same songs are being played. I've got over 13,000 songs loaded - it seems to me that I shouldn't be getting any repeats.

    When I want to randomly play (shuffle) all my songs, it seems that the same songs are being played. I've got over 13,000 songs loaded - it seems to me that I shouldn't be getting any repeats. I unrated all the songs, thinking this might affect how often a song gets picked to play. Any suggestions? Thanks!

    unfortunately, that is how GB works, it only offers a score for a single track at a time

    Most likely, water damage.
    You can try putting your iPod in a tupperware, half filled (maybe half inch) with rice grains, close the cover for about a week.
    If you have done this, as soon as it got wet, higher chances of success, now looks like the water moisture is getting to the LCD screen.
    Then you can always bring it to Apple Genius bar, for a an overhaul. (may cost you half the price of a new iPod classic.)

    My computer failed and the main drive had to be formatted but all my music was on a separate internal hard drive. So I downloaded the latest iTunes , problem is it has found all my songs but seems to not recognize half of the album data, half of the artists, all of the dates and all ratings data.
    I had a large part of it backed up on DVD's but it does not want to recognise them either?
    Any tips?

  • I am in switzerland and would like to download movies to my iPad but all the movies available seem to be in German? How can i download movies in english?

    I am in switzerland and would like to download movies to my ipad but all the available movies seem to be in german? How can i find the selection of the movies in english?

    No, you need to be in the UK with a UK billing address on your account to use the UK store
    You can try requesting that the English language versions be added to your country's store (you've checked to see if the film's description page says if it has alternative languages on it ?), but unless the film studio/rights-holder agrees to it then Apple won't be able to sell them there : http://www.apple.com/feedback/itunes.html

    Eh? Documents is a folder. You keep your documents in it. Or do you mean this thing...
    That's the Trash, it's where you put stuff that you no longer want.
    Yes, you are suppose to empty it occaisionally.
