Question regd Inheritance. Please read

In Inheritance,when a subclass extends a Superclass,
the subclass is a specialized version of the superclass.Right?
class B extends A{
So,B is a specialized version of A.
Supposing that class B also implements an Interface:
class B extends A implements iFace{
So now:
Is B a specialized version of class A or a specialized version of an interface?
Please can anyone answer?

nope ist not a specialization od the interface. there right terminus would be class A is an implementation of the interface.
interfaces have no behavoir, the are more sort of a method template which has to be implemented by another class. so something that has no behavoit cannot be specialized.

  • Question regarding Inheritance.Please HELP

    A question regarding Inheritance
    Look at the following code:
    class Tree{}
    class Pine extends Tree{}
    class Oak extends Tree{}
    public class Forest{
    public static void main(String args[]){
      Tree tree = new Pine();
      if( tree instanceof Pine )
      System.out.println( "Pine" );
      if( tree instanceof Tree )
      System.out.println( "Tree" );
      if( tree instanceof Oak )
      System.out.println( "Oak" );
      else System.out.println( "Oops" );
    }If I run this,I get the output of
    Pine
    Oak
    Oops
    My question is:
    How can Tree be an instance of Pine.? Instead Pine is an instance of Tree isnt it?

    The "instanceof" operator checks whether an object is an instance of a class. The object you have is an instance of the class Pine because you created it with "new Pine()," and "instanceof" only confirms this fact: "yes, it's a pine."
    If you changed "new Pine()" to "new Tree()" or "new Oak()" you would get different output because then the object you create is not an instance of Pine anymore.
    If you wonder about the variable type, it doesn't matter, you could have written "Object tree = new Pine()" and get the same result.

  • Question regd Inheritance Concept in 00 design

    So,B is a specialized version of A.
    Supposing that class B also implements an Interface:

    So now:
    Is B a specialized version of class A or a specialized version of an interface?
    Please can anyone answer?

    Both. You can treat it as class B, class A or
    interface iFace.
    This is how you get multiple interface inheritancein
    Java.Agree on the implmentation, disagree on the theory.
    B is a specialized version of A, but the interface is
    more a facet of B.No. In "class B extends A implements C" B is-a C just as it is-a A.
    For instance, a suburu imprezza is a specialized form
    of a car - but when my wife's brother add a load of
    rubbish to it, these are interfaces that it is
    implementing. It might be implementing the
    'SillyExpensiveAlloyWheels' interfaceThat's a poor design. You wouldn't have a care implement an interface for it's accessories as it doesn't make sense to say a particular type of care is-a SillyExpensiveAlloyWheels (ignoring the singular/plural mismatch).
    Look at the Collections framework.
    LinkedList is a list. It is a Collection. It is a Serializable. It is a Cloneable. It is an Object.
    An interface that a class implements is not just a "facet" of that class.

  • Question.! Please read this. I need help.

    So I just got my Palm Pixi yesterday night. I was wondering if you can download 3rd party apps from your computer? If so what sites can I go to? and how do I put them onto my phone?

    Hello and welcome to the forums;
    We have a built-in App Catalog available on your device, but there are alternate app feeds (web distribution and Beta apps) available at websites such as projectappetite.com and precentral.net. When you find an app that you want, you are prompted for your phone number and an SMS message is sent to you with the link to the application. Once you tap the link from your device, you can install the app just like you would from the app catalog.
    Hope this helps,

    Please read my question carefully, this is, I think, a question for the experts. It's not the usual name change question.
    When I setup my new MacBook Pro, something slipped by me and my computer was named First-Lasts-MacBook-Pro (using my real first and last name).
    I changed the computer name in Preferences/Sharing to a new name and Preferences/Accounts to just be Mike. I can right click on my account name, choose advanced, and see that everything looks right.
    However, If I do a scan of my network with my iPhone using the free version of IP Scanner, it lists my computer as First-Lasts-MacBook-Pro! And it lists the user as First-Last.
    So even though another Mac just sees my new computer name, and my home folder is Mike, somewhere in the system the original setup with my full name is still stored. And it's available on a network scan. So my full name might show up at a coffee shop.
    Can I fully change the name without doing a complete re-install of Lion and all my apps?

    One thought... you said the iPhone displayed your computer's old name? I think that you must have used the iPhone with this computer before you changed the name. So no one else's iPhone should display your full name unless that iPhone had previously connected to your Mac. For example, I did this exact same change, and I use the Keynote Remote app to connect with my MacBook Pro. It would no longer link with my MacBook Pro under the old name, and I found that I had to unlink and then create a new link under the new name. So the answer to your question is, there is nothing you need to do on the Mac, but rather the phone, and no other phone will display your full name.

    . How to Contact Support
    Please note this is a peer forum and Creative's Support staff do not guarantee a reply here. If your issue is urgent, you are within your warranty period and/or you do not get a fast reply here you should contact Creative Labs Technical Support.
    To contact support click the Support > Contact Customer Support link on this page.
    When contacting Creative Support by email it's important to note that you must reply to the autoresponse email you first receive, as detailed in the email itself. Also make sure to check any spam trap you have on your email system if you have not received a reply.
    It's also important if you feel that you have a bug or defect with your product to register that issue directly with support. Don't rely on the forum to raise awareness of an issue.
    2. Hot Topics
    This is dividied into 3 sections: General, Tag based players & USB mass storage players.
    Make sure to also look at Section 3, which covers some of the other General Issues.
    General
    Where do I get the latest software, drivers and firmware?
    Click the link Support > Downloads on this page.
    In general, when installing on a new PC you need to download the driver, and some software to communicate with the player e.g. MediaSource, Media Explorer. For players using the v2.xx MTP/PlayForsure firmware drivers are not necessary, but you must have Windows XP and Windows Media Player 0 (this provides the MTP driver).
    Important: Even though files are described as updates, none of the software requires a previous version to install. At worst they will prompt you to connect your player to verify you own a Creative product.
    Note if you are downloading MediaSource make sure to download and install the relevant MediaSource plugin for your player. If MediaSource can't detect your player this is the first thing to check. For the v.xx PDE firmware the plugin is called the Creative Zen and NOMAD Jukebox plugin for Creative MediaSource , and for the v2 MTP/PlayForSure firmware it's called Creative MediaSource Plugin for PlaysForSure devices .
    I am completely new to MP3 players, where should I start?
    Have a read of my Nomad Primer, so called as Creative's MP3 player range tend to be prefixed with the word Nomad.
    I think I have a bug, how can I check?
    There's a known bug list hosted at my site here. If you want to add a bug then please
    I have a wish request for the player, what can I do?
    You can post it here (see the petitions listed in Section of this FAQ), email it to support, and/or add it to the public wishlist I host here by
    I'm having connection problems with my player
    If you can, the best test is to try your player with another PC, to see if you still have the problem. This localises whether the problem is with the PC (most likely the USB) or the player. See the link below (search on "connection problems") for a lot more troubleshooting on this.
    What bit-rate should I encode my music at?
    Ultimately it's down to your ears what bit-rate you prefer, and you should listen for yourself to determine it. If you ask on the forum you'll get many different opinions.
    Make sure to look at the "MP3 vs. WMA" link below also.
    How long should my battery last?
    For the Zen and Nomad Jukebox players, to get some idea of how long your battery will last for a given bit-rate look at the battery curves thread. Ultimately battery life is dependent on how you use the player, make sure to follow the "why doesn't my battery last as long as expected?" link below.
    How long does an RMA take?
    Typically 2 weeks. But it might take a little longer, so don't start posting if it's 5 days.
    I want to know how people feel about their Zen Micro/Touch/MuVo etc.
    There's a long post titled Experience with your Creative player that has many posts from users about their players. Please search back for threads about specific players before starting a new thread.
    Where can I buy online music or get legal downloads for my player?
    See this thread.
    My tracks don't play at the correct speed e.g. they play too slowly, why?
    Chances are they are encoded in an unsupported sampling frequency. The tracks will need to be re-encoded at a supported bit-rate and/or frequency with something like Creative's MediaSource Audio Converter or dbPowerAmp.
    Can a Creative player work on an Apple Mac?
    It isn't officially supported, but some kind folks out there have written freeware applications to get your Creative player working with Macs. XNJB provides support for the Zen players, and requires OS X 0.3 or 0.4 (check the site for full details). MuVoHelper solves some problems with getting the MuVo to work optimally. The iTunes Zen plugin should support all Zen players. Note if the link to the plugin is broken just Google "iTunes Zen plugin" to find other sources. Also note there's no guarantee that these programs will work with the Mac, so if you have issues you should address your problems to the developer(s) of the relevant program.
    Can a Creative player work on Linux?
    Again it isn't officially supported, but again some kinds folks out there have written freeware applications to get your Creative player working. There's the Gnomad2 project. And don't forget the Linux forum at Nomadness.net if you are still having problems.
    Tag Based Players
    This section covers the players that use a hard disk and work using tags e.g. Zen Xtra, Touch, Micro, Sleek.
    My Zen is not behaving properly, won't startup, or goes into rescue mode. What should I do?
    If the Zen is not starting properly or not behaving correctly, first try to reset it. To reset all players except for the Zen Micro there is a small switch on the side of the player typically, that you should press using something like a bent paper clip. Don't use anything sharp. To reset the Zen Micro simply remove the battery and replace it.
    If this doesn't work then access rescue mode, and try running a disk cleanup.
    Next you should try reloading the firmware/OS, but beware if you are having connection problems also with your PC you may end up with a player that has no firmware and cannot be reloaded.
    The last resort is to format the player. This will erase the contents from the player, including the content that ships with the player.
    If none of these resolve the problem and you are under warranty you should get in contact with support to arrange replacement of the player.
    If you aren't under warranty Creative will still repair the player, which you can arrange by contacting support.
    How do I do a Disk Cleanup and/or access Rescue/Recovery Mode?
    Refer to the sticky Rescue Mode thread. Disk Cleanup is accessed from this. Note that the MuVo players (with the exclusion of the MuVo? players) do not have Rescue Mode.
    How long should a Disk Cleanup take?
    It should only take a few minutes, and no longer than 30 minutes. Anything longer than this and there is a problem with the player and you need to contact Creative Support.
    How long should a format take?
    Only a few seconds. Anything more than a minute and there is a problem with the player and you need to contact Creative Support.
    Although I can get into Rescue Mode, I can't select any option, or the options don't work?
    If Rescue Mode is not working properly or commands can't be chosen the player is faulty. You need to contact Creative Support.
    When are the Zen 20Gb/Neeon going to be released outside of the Asia Pacific region?
    Due to popular request the Neeon is launched in the USA, but nowhere else for now. If you want the Neeon then contact your regions Customer Services to request it.
    The Zen 20Gb is available from some shops in the USA and Europe e.g. Cambridge Soundworks, and Amazon.co.uk.
    Is there a known issue with the Zen Micro headphone socket?
    Creative Support have neither confirmed nor denied it officially. Some users have posted purported emails from Creative on the forum saying that the socket has been reinforced, but these have not been confirmed by Creative Support either. The exact incidence of the problem is unknown, but newer players seem to suffer less from it.
    Should I buy the Zen Micro or Touch etc. and what colour should it be?
    We can't tell you what player to get, or what colour it should be. Look at your collection size and the features of the player (see Nomadworld.com for the product pages) and decide yourself based on this.
    Why does my Zen Micro battery drain so quickly?
    The standby time (24 hours from turn-off) for the Zen Micro seems to use a lot more power than previous Zens. Creative have released both v (..0+) and v2 (2.20.05+) firmware that reduces the standby time to 4 hours. Make sure to update to one of these if you have a draining problem.
    Also see JazzMC's detailed page on this problem.
    Why is my Zen Micro/Touch Touchpad so sensiti've and/or difficult to use?
    The Touchpads take some time to get used to.

  • One very basic question about inheritance

    One very basic question about inheritance.
    Why we need inheritance?
    the benefit of inheritance also achieve by creating instance of base class using it in other class instead of extending the base class.
    Can any one please explain why we are using inheritance instead of creating object of base class????

    Can any one please explain why we are using inheritance instead of creating object of base class????What did you find out when you looked on Google?
    One example of inheritance comes in the form of a vehicle. Each vehicle has similarities however they differ in their own retrospect. A car is not a bus, a bus is not a truck, and a truck is not a motorbike. If you can define the similarities between these vehicles then you have a class in which you can extend into either of the previous mentioned vehicles. Resulting in a reusable class, dramatically reduces the size of code, creates a single point of definition, increases maintainability, you name it.
    In short there are thousands of benefits from using inheritance, listing the benefits could take a while. A quick Google search should give you a few hundred k if not million links to read.

  • Regarding no employee discount message! Please Read everything and you will know

    come on does anyone read what the sign says anymore? The first page when you go to www.verizonwireless.com/iphoneorder says in big bold letter PLEASE READ BEFORE ORDERING
    It then goes to say, that employee discounts on plans will be honored. It also goes on and says that you will not see it during checkout, but it will be applied to your monthly discount... Then it gives a link and says after you receive your iphone to go to this webpage to make sure employee discount is still on phone.....
    I mean why doesnt anyone read anything before ordering.... Verizon would be a genius if they put in big bold print, that you where signing a 10 year contract, and had to give your first born child up, because no one would care.... This is a contract your signing you should read everything! Then maybe people wouldnt need to ask all these questions...
    Sorry hope everyone enjoys there iphone just get sick of people asking questions that are already answered if they just looked

    I am one of those people interested in what you speak of. I looked at your link and it doesn't mention anything of the sort. I have completed placing my order and the only thing I saw was the first question in BOLD is the message you refer to in the subject. Can you post the link to the information you write about so I can see what you are saying for myself? When you can do that, then beat me up for not reading.

  • Safari logs me out of logged in web pages - not the same problem as other similar post - please read.

    Before you crucify me please read the problem I've outlined below, because it's not the same issue other people are having. I did research the forums for the particular issue I'm having and it's not the same as what's already been posted. Please let me explain.
    Here is my machine info.
    iMac running Mac OS X Lion 10.7.5 on 2.5 GHZ Intel core.
    Safari Version 5.1.7
    I run two instances of Safari. I will have 1 safari browser window open on the left side of my screen with 7 tabs all on pages that require login. I run a second instance of Safari on the right side of my screen with only one tab open logged into 1 web page.
    Here's what happens. Ocassionaly when switching the focus from one browser to the other all of my logged in web pages will refresh and I'll be logged out of all my logged in web pages, on both open browsers. There's never a certain amount of time that this happens, I've had it happen 3-4 hours into my work day and I've had it happen 10 minutes into my work day. I've also had this occure when I'm putting the focus from one browser window to the other and then I go to resize the width of the window I just put the focus on.
    I'm thinking that there must be some setting or short cut "gesture" built into Safari that I'm triggering to make this happen, however I have looked at all the settings and can't seem to find anything that would cause this.
    Any help or advice is apprecaited.  

    BDAqua - I have two Safari windows open - I guess in my semi technical mind that equated to two instances. But your probably right, just one instance of app with two windows open.
    About two minutes after I posted my question, I was doing some work in one of my tabbed web pages, as I pressed the submit button to update the record on that page and as the page was refreshing I clicked my mouse on the second open Safari window to put the focus on that window, as soon as I put the focus on the second open browser I got logged out of all my logged in tabs in both windows.
    The time it happened was sometime between 14:30 and 14:35
    I'm looking at the Sytem Log. IN the filter I typed Safari and nothing came up from today in the log.
    Just looking at "All Messages" between the hours of 1430 and 1435 their are no messages about safari, just the following.

  • Users with NoClassDefFoundError & nested jars - PLEASE READ!!

    A hell of a lot of the traffic on this forum is to do with getting a NoClassDefFoundError while trying to access classes that are inside a jar within your own jar.........please please please read this if you're having this problem, it will explain what's going on, and will save you from having to post the same question for the millionth time!!!
    Unfortunately you can't embed jars within a jar and expect them to be referencable for the classpath from outside the main jar. The "Class-Path" attribute in the manifest is used to refer to other jar files outside of your jar file.
    The usual approach to solve this problem is to unpack the jar files you want to embed and then rejar everything together in one big jar file again. This isn't always a great approach though, I know I'm looking for an alternative. So far my only alternative is dynamic class loading using a classloader, however this isn't great if you need to refer to several hundreds or even thousands of classes.

    As I replied in another post (http://forum.java.sun.com/thread.jsp?forum=22&thread=416726&tstart=0&trange=100) I think Sun should really add this capability to the JVM itself. Perhaps a new file format, .aar (for Application Archive) that the JVM DOES read embeded .jar/.zip files from. Even if it is only one level deep, that would be extremely helpful. I have built a plugin engine and originally was packaging my plugins in .jar files. But if a plugin "wraps" a library like ant.jar or something, you are out of luck, the plugin has to be un-archived to the disk for it to work. We came up with a solution, which is a .par file (for plugin archive) that does embed everything, but the engine itself at runtime un-archives the .par file into a "working" directory behind the scenes. While this does work, the main problem is if you deploy an app with a lot of plugins it takes a while to un-archive everything before the app initially starts.
    Our next step is to do what Carter says, build a custom jarjar classloader. That is, we'll extend URLClassLoader, and in the loadClass() call (for our plugin engine we break the normal go to parent loader first tradition) we'd have to "scan" a plugin .par file for any .jar files. If the .par file contains .jar files, we then retrieve those and scan them in memory for the class we are looking for.
    As I explained there are no doubt several ways to make this fast. The classloader would want to keep a list of all packages found and in what .jar/.zip they were found in, so as more classes within the package of a given .jar are asked to be loaded, the engine knows exactly what .jar/.zip to jump to. Also, OS hd caching will most likely take affect somewhat thus if many classes from the same .jar file are required it is possible that .jar file would be cached and multiple i/o access will not take place.
