What Should I Aim For Next?

Hello Forum Members, For a year (actually less) I've been in a AP Computer Science class learn with my teacher and fellow students the secrets of the the Java language, I find most of it very intutive, as we focus mainly on the concepts theories, algorithism, and logics of programming (With Java as the principal tool of learning). We were taken from Hello World all the way through OOP basics, the method and class designing, interfaces, Array/ArrayLists, and some inheritance. (I had to learn GUI and Event handling on my own though).
Now that I the teacher has just breeded new confidence in me I am actually trying to take things to the next level. (school is waaay to slow, some lucky fellas in my class are actually still having trouble calling their own methods). What do you guys suggest me do? Books, Tutorials (Please be very specific :), Online Courses, Activities? I am also working on a mammoth (at least it seems to me) programming project that will demand a lot more of me.
Any input is very welcomed, thanks.

I am currently reading : Java Demystified by Jim Keogh.
So far, I have found it to be a great book, but of course, it is the only book I have read.
I currently have Sams Teach yourself Java 2 In 21 Days, which is a monster book. It looks like it provides much much information.
The best way I have seemed to learn is to follow up ideas you have read i.e. small programs, or large programs.
It seems that I think I have gotten the concept when I read out of the books or online tutorials, but when it comes to writing the file, I forget. So then I have to look back, and blah. After I write it and get everything compiled, it seems to stick in my memory better.
This is a good online tutorial. Dunno if you have seen it or not:

And I remember visiting this site awhile back:

    If not this:
    iOS: Wi-Fi or Bluetooth settings grayed out or dim
    One user reported that placing the iPod in the freezer fixed the problem.
    Also heating sometimes works. See:
    Why can't I select my wifi settings?
    A trick that works frequently with iPhones:
    Settings > AirPlane Mode ON, Do Not Disturb ON
    Power down and wait 5-10 minutes
    Power up
    Settings > AirPlane Mode OFF, Do Not Disturb OFF
    If not successful, an appointment at the Genius Bar of an Apple store is usually in order.

    Then:
    Does the iOS device connect to other networks? See other networks? If yes that tends to indicate a problem with your network.
    Does the iOS device see the network?
    Any error messages?
    Do other devices now connect?
    Did the iOS device connect before?
    Try the following to rule out a software problem:                
    - Reset the iOS device. Nothing will be lost
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Power off and then back on your router

  • What should I think for 865PE Neo3-F and 3.0 ghz?

    with this mobo
    MSI "865PE Neo3-F" i865PE Chipset Motherboard For Intel LGA 775 CPU
    and this CPU
      Intel LGA 775 Pentium 4 540J 3.2 GHz, 800MHz FSB, 1MB L2 Cache 
    what should I exspect for a super stable overclock?  Does the motherboard have tons of options? 
    Im going to be de clocking the memory so I can get a higher clock speed.  Let me know if you know how well the options are.  Thanks.   
    I hope at least 3.6     (It will have  extra cooling    40 degree datacenter)

    There's not only MSI make 775 with old chipset.
    DFI even make 775 with 875 chipset. And in my country (in a mag), they complain it's faster than 915. -yes, I think it's right, no surprise-
    I think it's not about OC but more about price. As the chipset is cheaper, and use AGP + DDR1, so you can still use most -expensive- part of your previous system.

  • Need Help..what should i use for this

    hello friends, i have to write a program which will load an xml file reader class at run time and depending on the content of xml file i'm going to generate mapping.. e.g xml file- <MyMapping> <ATO> <security type=int> </ATO> <FIX> <symbol type=String> </FIX> </MyMapping> Now i want to change the content of xml file without restarting my running application..changes should be reflected at runtime... also my xml file will contain nearly 1000 lines..so in this case which technique should i use whether i use JAXB which will give the classes of my xml file or any other ?? Also if i use JAXB whether JAXB gives classes corrsponding to my xml nodes (e.g ATO.java as per above example).

    Now first i have to parse this xml ..then my java program is going to accept value from user ..and depending on user specified value i've to use either ATO or FIX fields...e.g if user value is 35 then my program should use fields within ATO node.
    You will read the XML structure into some kind of memory model. When the user supplies a value you will search for a matching value (likely from a collection such as a map or list) and return the value in that object that you locate.
    what should be done for this ..
    See above.
    and what if i change values in my xml file..will i have to restart my application to load xml again ?
    If you change the file on the filesystem, you should simply be able to re-parse the XML file and update your in-memory model. If you instead update your in memory-model, you can serialize the model back to XML on the filesystem. Neither needs to necessarily have anything to do with application start-up (other than the fact that you would normally read in the XML model then, but updating is a separate concern, as would re-reading it).

  • I have Mac OS X Version 10.6.8 ,I want to buy the updated operating system that puts iMessage and Facetime on my Macbook Pro. What should I search for, and then purchase, in the App Store?

    I have Mac OS X Version 10.6.8 ,I want to buy the updated operating system that puts iMessage and Facetime on my Macbook Pro. What should I search for, and then purchase, in the App Store?

    FaceTime can run in the version of OS X that you currently have. To get Messageyou need Mountain Lion. The protocol used by Messages is iMeassage.
    The question is does your MBP meet the specs for Mountain Lion.
    iMac (Mid 2007 or newer)
    MacBook (Late 2008 Aluminum, or Early 2009 or newer)
    MacBook Pro (Mid/Late 2007 or newer)
    MacBook Air (Late 2008 or newer)
    Mac mini (Early 2009 or newer)
    Mac Pro (Early 2008 or newer)
    Xserve (Early 2009)
    Your Mac needs:
    OS X v10.6.8 or OS X Lion already installed
    2 GB or more of memory
    8 GB or more of available space

    I have changed your XML to make it well formed. Please refer this further in this reply.
    Well Formed XML:
    <Message>
         <ATO somefiled="X" type="int" value="35"/>
         <FIX somefiled="Y" type="String" value="50"/>
    </Message>

    what should be done for this ..A simple XPath Query can do trick for you, it can give you ATO or FIX element according to user specified value. XPath query can be:
    // replace ##user_specified_value## with value user enters.
    String xPathquery= "/Message/child::*[@value='##user_specified_value##']";

  • In explorer when I go to my banks sites - I see a lock - what should I look for in Fkirefox

    I have only used explorer - so I am new to this browzer. When I visit my bank or am about to use paypal I see a lock, so I know the site is secure - what should I look for with Firefox?

    They've been silly and removed it.

  • I need to publish a magazine in arabic and english - what should I buy - for how much to use 15 mac books for my students to use indesign?

    I need to publish a magazine in arabic and english - what should I buy - for how much to use 15 mac books for my students to use indesign?

    You can only return the machine if you're within 14 days of purchase - otherwise you're just 'stuck' with what you purchased (unless you sell it, of course).
    I always recommend that Retina owners order 16GB of RAM as the RAM is not upgradable - it's soldered onto the logic board.
    Your call - if you're with 14 days of purchase, take it back and exchange for a 16GB model. Or sell it and buy a model with 16GB. The higher amount of memory will allow you to run far more memory-hungry apps concurrently.
    Good luck,

    They may not have the updated Facebook app. I have a 4S and my Facebook will not rotate. You can use Google and find more information about this. I'm just reporting what is going on and why it is happening.

    Sorry , but product is iPhone 5S

    You can't buy from the Apple store online in the US because it is country specific and you firstly need a US credit card and then a US address and they won't ship outside of the US so you can't.
    No Apple online store will ship outside the coutry.
    If you want an iPhone, then you'll have to order via the Russian Apple store online if there is one, or you'll have to wait until it is released in your own country or go and buy one in Europe.

  • S apple coming out with a new version for Macbook Pro MD101HN/A ? what should i go for Macbook Pro or Macbook air since my usage are basic mainy internet , word , excel , powerpoint etc.

    Is apple coming out with a new version for Macbook Pro MD101HN/A ? what should i go for Macbook Pro or Macbook air since my usage are basic mainy internet , word , excel , powerpoint etc.

    souvikfromKolkata,
    you’ll know as soon as the rest of us do if Apple decide to produce a new non-Retina model. My guess would be that they won’t do so, but that’s only a guess.
    With Internet, Word, Excel, and PowerPoint representing your main usage, either a MacBook Pro or a MacBook Air would be suitable for you.

  • 1,1 running Lion with XP Boot (re-install and what should i use for recovery disk or usb stick)?

    i am trying to give my 1,1 mac pro a little love and would like to keep this machine running lion. i also have a boot camp installation of XP on it.
    1. can anyone give me instructions on how/whether i can basically do a fresh install of Lion on this machine and minimize the system so it is not cluttered up with all my previous software etc, etc while still maintaining the original XP boot camp partition which i really need to have?
    2. can anyone clarify for me what i should have on hand /if/ i need to boot into recovery mode or some other safe boot mode? i recently ran into an issue where i may have had to use the old Disk Utility format function and there was a reference to booting using the DVD install disks. however i am really confused as to what i should have on hand. ALSO the last time i had to do something on this machine i was told to boot into the Recovery Partition and it appears for some reason (perhaps because i had a "non-standard" windows 7 boot camp installation on the drive at the time??) that there was no recovery partition created when i upgraded to Lion.
    - /anyway/ i am finding that i have the two ORIGINAL install disks for the mac pro on hand, a Max OS X Leopard and a mac OS X Snow Leopard DVD on hand but i am thinking that i should be creating some kind of USB stick similar to the one i created with yosemite? actually, i am not even sure what this USB stick for yosemite is for but i guess i can use it to boot into safe mode or something?
    THANKS for any help as i'd like to get this business under control a little better in case i have an issue.
    i'd also like to install Lion so that there is a Recovery Partition if possible and i think this may be possible if i don't have the windows 7 partition in the machine when i do a fresh install. any help would be great. thanks.

    You have to go out of your way to build the Installer Disk yourself. But this tool makes it easy, and this site contains instructions:
    http://diskmakerx.com
    the bootable installer is basically to re-install the OS if i have to
    Yes.
    the recovery partition is somehow for fixing a problem
    Recovery can go and get you the software and re-download it and start the Install, and allows the use of Disk Utility and can reset passwords.
    or is there some overlap?
    Yes. Both give you access to the Utilities that used to be on the Installer DVD. Disk Utility to Repair or initialize and a few other tools that can allow you to set up to install on an otherwise-bare disk or change your password.
    is "Safe Mode" something completely different
    Safe Mode is a way to start the fully-Installed Operating System in a special way. It first does one pass of Disk Utility (Repair Disk) against the Boot Drive. [Normally this would require booting from a different drive to make repairs.] Then it loads a minimal set of Apple-only kernel extensions, and uses a one-size-fits-all screen resolution. Then it demands your Username and password to proceed.
    From there you can fix settings, use the Finder to add or delete things, and check operation with minimal extensions versus all your daily-use extensions. Very helpful for debugging extension conflicts and graphics settings problems, and fixing damaged settings. The next Restart builds a new extensions cache.

  • I am running on Snow Leopard - what should I upgrade to next

    I know I need to upgrade from Snow Leopard but what do I go to next??
    MacBook Pro 5.5, 2 GB of memory 10.6.8

    Back up your data, check your applications for compatibility, and download Mavericks from the Mac App Store. You should install more RAM in the computer if you choose to upgrade.

  • What should be needed for cost reports to be activated in Business Content?

    Hi experts,
      I am completely new to Business Content so sorry if I ask a silly question. Currently we are trying to migrate custom fixed queries to queries from Cubes in Business Content, because the company has growed in the past years.
      Our first stage is to have the new queries that report costs for the company.
    The reports should consider manufacturing costs such as
    - maintenance
    - outsourced special services (providers)
    - new machinery
    (not energy or service costs)
    This reports should include country, plant, date, amount, etc.
    I have been searching for the modules or cubes that should be activated for this requirement.  So far i found that in MM there is a cube 0SRV_C01 that includes external services.
    The data from the InfoCube External Services enables you to carry out analyses of services. Using this data, you can obtain answers to questions such as the following: "How much of each service was ordered from a certain vendor?" "What was the order value per service for a certain plant?"
    However there should be another information where manufacturing costs could be exploited.
    ¿Can anyone give me some advice on how to resolve this requirement? ¿ does anyobody know which cube(s) include the information I am looking for?
    Thanks,
