A few questions if you please.

Hi there, its taken me about a week to find my way to these forums, I have to say, they look pretty nifty.
So, I'm new here .. I began to teach myself Java about a week ago, I have a book by Mr Barry Burd, have installed Jcreater and, I've started chewing my way through Barrys book.
My background is in web design, Xhtml, CSS and I have a great love of php and mysql, although Java will be my first trip into the world of OOP.
I haven't really had any problems with the basic stuff so far, at a basic level its all nice and procedural, and even feels a little like php, I'm sure this will change soon though.
My confusion is probably born of the fact that the book I'm using to learn from is possibly out of date.
Since im fast approaching the end of this "beginners" book, im going o need something more.... shall we say "meaty" to get my teeth into soon.
Im especially looking for something to introduce me to Coding GUI's and i need to get a proper feel for OOP... so id appreciate any recommendations on either books to go and buy ... or online tutorials to read.
I'm mainly confused about what the latest version of Java is .... and what the different variants are, and what they're typically used for.
The book I have is the Dummies book on "beginning Java 2" .... which sounded fine ... but when i went to download the software he suggested, it looked to me like i was downloading java 6 .... could someone clear this up for me?
I really don't want to be learning from an "out of date source"
ok, so in summary, because i realize that I've been waffling for some time =P
1) Can anyone recommend Books / Online tutorials for starting to code GUI's.
2) Can someone clarify the current version of Java we are on, and maybe help me understand some of the different variants.
Basically this isn't a programming question at all.... I'm sure they will follow .... I need some terminology explaining.
Sorry for the long post, but as its my first i thought i should make it a good one =P.
Thank you in advance to anyone who helps me

Hi and welcome :)
The latest version of java is 6 (1.6). But For learning java2 (1.4.x) is good enough. Stick to the Java SE (standard edition) first.
Another recommendation is NOT to use an IDE (JCreator) until you got the concepts of classpath and packaging. This is the regular list for beginners:
Sun's basic Java tutorial
Sun's New To Java Center. Includes an overview of what Java is, instructions for setting up Java, an intro to programming (that includes links to the above tutorial or to parts of it), quizzes, a list of resources, and info on certification and courses.
http://javaalmanac.com . A couple dozen code examples that supplement The Java Developers Almanac.
jGuru. A general Java resource site. Includes FAQs, forums, courses, more.
JavaRanch. To quote the tagline on their homepage: "a friendly place for Java greenhorns." FAQs, forums (moderated, I believe), sample code, all kinds of goodies for newbies. From what I've heard, they live up to the "friendly" claim.
Bruce Eckel's Thinking in Java (Available online.)
Joshua Bloch's Effective Java
Bert Bates and Kathy Sierra's Head First Java.
James Gosling's The Java Programming Language. Gosling is
the creator of Java. It doesn't get much more authoritative than this.
Regarding GUI programming you can have a look at this tutorial:
http://java.sun.com/docs/books/tutorial/uiswing/index.html
Have fun!

  • Travel to UK with iPhone next week. A few questions if you please!

    My daughter is going to visit the UK next week. She will be bringing her iPhone. I have bought her a plug adapter that does not convert voltage because it is my understanding that the Apple adaptor will take 220 fine. Also, the data roaming has been turned off. She has been told not to try to use the internet unless she has WIFI access. I will call ATT on Monday to buy international calling, which brings the roaming charges down a little, but not much.
    Now the questions: Will the phone work in the UK reliably? How the heck do you dial an american phone number from the UK Let's say you want to dial 714-555-1212 from the UK, what prefixes are needed when you dial. I don't want her to place her calls with operator assistance! Any other comments would be greatly appreciated, TIA.
    Paul

    When you put numbers in a mobile phone, it's always best to enter internationally formatted numbers.
    For the US, that's +1 714 555 1212 for the number you mentioned, or for a UK number such as 01312 345678, it'd be +44 1312 345 678 (leave out the first '0'). Obviously, +1 is the US country code, +44 is the UK. Check out this wikipedia link for other countries: http://en.wikipedia.org/wiki/Listof_international_callprefixes
    The iPhone - even the US iPhone, works fine in the UK, as it's a GSM phone (the technology used for pretty much every country's predominant cell networks except the US). Mine's been without issue.
    One thing that nobody thinks of, but everyone could possibly need - emergency services. It's a common misconception in the UK that 911 works, but it will not. Remember to use 999, or the European-wide (and world wide for GSM phones) 112
    Oh yeah, and last but not least, visit Scotland, especially the highlands.

    Dear I forget my security questions , could you please guide me

    Contact Apple through iTunes Store Support, and explain that you have forgotten your 3 security questions, that you can reset your password, but doing so doesn't reset your security questions.
    Explain that after resetting your password, you are still asked for the answers you have forgotten, before you can gain access to My Apple ID > Manage your account > Password & security, which is where you need to be to change your answers.
    Remember, support will receive hundreds, if not thousands of requests per day, some from people trying it on, others with little explanation and others that are written extremely poorly. Take the time to explain your situation properly, be precise and concise, brief but comprehensive.

    5. All versions of SAP Till Now?
    Thanks!!

    Im pretty new to all this too, but this is how you validate an XML file against a XSD:
    You need to set the features of youre parser so that it is ready to validate.
    You will also need to extend the SAXErrorHandler with youre own CustomErrorHandler,
    parser.setFeature("http://apache.org/xml/features/validation/schema", validate);
    parser.setFeature("http://apache.org/xml/features/validation/schema-full-checking", validate);
    parser.setProperty("http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation", schemaUrl);
    CustomerErrorHandler handler = new CustomErrorHandler()
    parser.setErrorHandler(handler);
    parser.parse(xmlFiles);The XML file then needs t o have a reference to the XSD that is needs to be validated against at the top of the file:
    xsi:schemaLocation="http://www.w3schools.com c:\\WINNT\Desktop\youreXSD.xsd
    I think you will also need to catch and handle at least the SAXException....
    Hope this helps,

  • Few questions about the MacBook

    Hi.
    I'm gonna buy a macbook within a few months, and I have a few questions for you all!
    Here are the questions:
    1. ) Is it worth $1,299 + Tax, USD?
    2. ) When will Apple release the next gen. of macbooks?
    3. ) How well does it play games?
    4. ) How heavy is it?
    5. ) How does the keyboard style feel compared to other laptops?
    6. ) How long does the battery normally last while using wirless?
    7. ) What is the Macbook lacking?
    8. ) Does it get as hot as a car, like its predisesor?
    9. ) Can you please send some pics of one next to some thing that we all have, like a quarter? (For comparison.)
    And finally, is there any thing I should know before buying?

    Here are the questions:
    1. ) Is it worth $1,299 + Tax, USD?
    Yeah. You are going to NEED that 1 gig of ram that's for sure. Plus, you get a double layer DVD burner, 20 extra gigs of hard drive space and a tiny speed boost from the 1.83 GHz. All this is costing you about $200 extra. The Ram and DVD alone would cost that much if you got them after words.
    However, I got the cheap $1100 one because none of those features are really that important to me. I really couldn't tell the difference between 1.83 GHz and 2.0 GHz and I doubt anyone else could either. I don't need a DVD burner built in because I have access to an external one. Maybe latter I'll upgrade to a larger HD (something like 300 GB though!). So, the only thing that really was lacking on my MacBook when I bought it was the the RAM. So, I spent about $140 for a 1 Gig stick and I feel a lot better now.
    2. ) When will Apple release the next gen. of
    macbooks?
    They already did. The Core2 Duo will most likely stick it out for a while. I could see them upping the MHz every now and then(this will happen more frequently with the Intel chips eg. quad core MacBook Pro or a 2.5 GHz MacBook ) but I wouldn't expect them to upgrade to a new hardware platform for the next few years. Not to mention that the MacBook is essentially a new product at the beginning of it's life-cycle. I could be wrong but I believe that this is it for a while.
    3. ) How well does it play games?
    Actually, I was surprised to find that it does pretty good. Since the video card shares memory with the system, Performance is very memory dependent. If you plan on playing a lot of games, go ahead and upgrade to the full 2 Gigs of RAM. I play Halo now and then without much of a problem.
    4. ) How heavy is it?
    Not at all. It's very thin and light weight.
    5. ) How does the keyboard style feel compared to
    other laptops?
    Well, different to be sure. But not in a bad way at all. In fact, I tend to have less typos then before because my fingers can fell the edges of the keys now. I actually like it a lot to tell you the truth.
    6. ) How long does the battery normally last while
    using wirless?
    About 3.5 - 4 hours give or take 30 minutes or so. I tend to close the lid a lot during the day when I'm not directly using it so that saves a huge amount of power. Seriously though, I was blown away by how long the battery lasts on this thing when I got it. My previous laptop (Sony Vaio), I could maybe get about 1.5 hours out it without being plugged in. No, this thing rocks as far as that's concerned.
    7. ) What is the Macbook lacking?
    Metal case, back lit keys, PC card slot, FireWire 800 and... well, if those things matter to you then you better get a MacBook Pro. Although is battery life is important then the MacBook will beat the pants of the Pro.
    8. ) Does it get as hot as a car, like its
    predisesor?
    By Predecessor do you mean the iBook? or the first gen/hot off the assembly line MacBooks? Either way, they do get hot. You can use one of the many fan control software to cool it down but most of us have just gotten used to it.
    9. ) Can you please send some pics of one next to
    some thing that we all have, like a quarter? (For
    comparison.)
    Sorry, I don't have one at the moment. It's definetly larger then an iBook but smaller then a MacBook Pro if that helps. I would suggest making a trip to your nearest Apple store.
    And finally, is there any thing I should know before
    buying?
    Universal Binary! That will become a very important word for you. Although the list grows day by day, the lack of Adobe products is like a stain on the MacBook/Pro. There is an entire industry that uses nothing but Adobe products. For them, Intel Mac's are not an option at this point in time.

    does not seem particularly specific – do you want to simply combine two images as they are, do you want to clip elements from the one and insert them into the other, …?
    Could you post (lores of) the images and explain what you intend to achieve?

  • Few question to get going w adobe stuff...

    Ok I have a few questions, maybe you can help me...
    A) ORGANIZER RELATED QUESTIONS:
    1) How/where do I back up photo/videos/settings from adobe organizer?
    1b) If I decide to upgrade from pse9 to ps cs5 is it real simple to 'import.transfer' organizer to the big dog ps cs5?
    1c) Same thing (but for videos) if decide to upgrade to premiere pro from premiere elements 9 is it easy to import organizer?
    2) Organizer - are there physical copies of my photos/videos in some other adobe organizer folder
    or are they just linked to similar to windows 7 and libraries?
    B) Photoshop & Premiere Elements 9 vs Photoshop cS5 & Premiere Pro
    1) Does After Effects work with premiere elements 9?
    1b) Recommend some good starter plug in collections for video editing.?
    2) If I decide to upgrade/buy photoshop cs5, do all of my plug ins I've got installed with elements 8 as host get automatically transferred to ps cs5? Or do I have to manually reinstall all over?
    3) How much simpler is photoshop elements to learn than ps cs5 and premiere pro?
    Is the learning curve about the same just more of it to learn (and additional function of course)
    Thanks everybody - have a ton more questions, but gonna lay low and watch some tutorials for about a YEAR first....
    One last thing...
    I love this site, but variety is the spice of life. Can you guys recommend some other Adobe ps/premeire learing sites and help/discussion forums that would be valuable

    A.1) Click File >>Back Up catalog to CD DVD or Hard Drive.
    1b) You can convert a PSE catalog in CS5 but works best with photos only. Project files like slideshows and videos might cause the conversion to stall.
    1c) Premier Pro has it’s own media browser.
    2)There are no physical copies. The Organizer only makes links to the folders on your computer.
    B.1)AE is fully integrated in CS5.5 Production Premium but I’m not sure if it works on a stand alone basis, although I don’t see why not.
    1b) Sorry don’t know any plug-ins to recommend but 32 bit plug-in's will not work with AE.
    2) You would need to move plug-ins manually.
    3) Just more of it. In PS CS5 you get great things like the pen/paths tool and tone curves. With Premier pro you ideally need a fast 64 bit system with high end GPU to take full advantage of the mercury Playback Engine.
    Try adobe TV for all sorts of video tutorials for the various products.
    Good luck.

  • A Few Questions About The GTX 580 Twin Frozr/OC in SLI

    Hi everyone!
    I have a few questions if you guys don't mind answering them, first thing though to make it clear this system is not built yet but the build will start soon.
    My first question is whether or not this PSU is capable of running two GTX 580 Twin Frozr/OC in SLI:
    http://www.newegg.com/Product/Product.aspx?Item=N82E16817139015&Tpk=AX850
    +3.3V@25A, +5V@25A, +12V1@70A, [email protected], +5VSB@3A
    My second question is whether or not the GTX 580 Twin Frozr/OC will come with a SLI bridge connector long enough to accomplish a connection over this distance:
    If not where can I buy a bridge capable of accomplishing this?, the reason for this distance is to keep the bottom card from pushing air onto the top one.
    The above is a normal ATX form factor motherboard or to be more specific a ASRock P67 EXTREME6.
    http://www.newegg.com/Product/Product.aspx?Item=N82E16813157231

    Quote
    EDIT-
    I'm looking at the picture right now and it looks like the bridge that comes with the motherboard is not long enough, any suggestions on where to buy one?
    nope no idea, ask your reseller
    Quote
    I didn't mean the Watts I mean the Amps, from other threads in this board it seems that some PSU's aren't up to the task of supplying the card with enough Amps, I was wondering if that PSU could supply enough for both.
    Well you can figure from the graph
    With one VGA it drains total 447W, where single 580GTX need 40A-42A,
    adding second the same VGA to the system drains total 719W
    So 719-447=272W, 272W/12=23A, 42A+23A=65A
    or simple 719/12=60A
    Quote
    BTW, I would also like to say I'm currently using a MSI board in my current build and I love it!

    CORSAIR HX Series CMPSU-650HX 650W ATX12V v2.2
    I have a few questions if you guys don't mind:
    1) The RAM i listed is speed 6. But it's only 6gb. I could spend more and get 12GB but it would be much slower (speed 9). I'm really only using premier, encoder, and encore. Little if no AE, etc. Will the performance gain be worth it to invest in slower 12GB ram?
    2) Any experience with the Matrox card? Everything I make gets exported to blu ray and some of it online (h.264). Seems like the $500 would be well spent.
    3) What is the cheapest version of Windows 7 that has the features someone like me would need?
    4) Is the PSU enough @ 650w? I plan on it powering 6+ HDDs.
