Need more Java Analysis

I have a few java books but none that give as many exercises as I need, is there a resource more in depth than the one on this site that gives exercises, and analysis as well as the written program? java.sun says it offers tutorials and hundreds of working examples, but all I can find are basic tutorials and some troubleshooting. The examples of error messages do not help much and the tutorials are what I find in most books. There isn't much in the way of program analysis or an examination of what the program is trying to do.
For example if I wanted to import a file, output the data in different ways, I can look through several books and see only one example that helps, and there is no analysis. I don't care about producing a GUI.
Thanks for any help you can offer, I think of java programs like math problems, but in mathematics there are exercises, answers, reasons...

Did you look at these tutorials?
http://java.sun.com/developer/onlineTraining/
I would not call all of them "basic".

  • NEED more than 15 menu item in Context Menu ????

    Hi,
    I really need to have more than 15 menu item displayed on Context Menu. I desperately need some workaround or ideas to achieve this
    My client has invested thousands of dollar in Flex Project, he definitely need more than 15 menu item.If this project failed , client will NEVER think to invest in flex.
    Had I been  aware of this limitation before I would have thought some solution by now.This comes as a surprise to me at the last moment ,just fews days before Prod Date.
    I cant also user java Scrip heck  as my Flex application is running inside Dot net Container , I do not access to the luxury of java script
    Pls gents help me get rid of this ...PLEASE provide some ideas.
    Thanks in advance.
    Thanks,
    Dharmendra

    Thanks Natasha,
    I got your point  but as for as I  know grouping like Quality is not possibel in Flax Context menu. I also cant go for window style menu(file,edit) because I need them to be displyed on DataGrid right clk . I am designing a trade datagrid where in trader can see all trades and he can approve/reject etc by just right clk and  selcting proper menu item form Context Menu.
    In case of window style (acrobat.com) menu trader will have to reach to  menu instead of  getting all options on mouse right clk
    I will have to think other alternative wich provides same ease as cotext menu.(God knows what is that )
    Once again thanks for suggestion.

  • Need more info abt the functions of each classes in Workflow API's of BPEL

    Need more information about the functions of each method of the classes in Workflow API's of BPEL
    The Java documentation of the workflow API (especially Identity Service classes) is having a one liner explanation for the methods of each class. We need to implement our own Identity Service that implements the BPMIdentityService interface. We are not able to map the function of each methods of this interface to what our security subsystem provides. We feel that we need more detailed information about what each method of each class is doing internally so that we can map to whatever our security subsystem provides.
    The BPEL Developers Guide does not talk about the functionality of each methods of this interface. If anybody can guide me to look into some documentation that has this information or if anybody has this information, then please do the necessary help.

  • Need more frames per second

    So, I've got this game engine I'm working on... and now that I've got it in a working state it's slapped me in the face with some pretty low frame rates..
    don't get me wrong, it's not horrilbe. In fact, I can get about 200fps on my 450Mhz laptop in both windowed mode and as an applet...
    but as I increase the amount of Image data that gets drawn to the screen the frames start to drop to unacceptable levels. Also, when I increase the size of the window the frame rate dropps horrendously.
    I get the 200fps when I am only drawing a 20k image to a screen that's 200x200.
    The best I'm getting is 72-75fps in a 320x200 window drawing 144k of image data to the screen.
    to draw the images I'm using
    Graphics::drawImage(Image, int, int, Component)
    The speed drop is definitely related to the amount of image data that I'm drawing to the screen and the size of the screen that I'm drawing to.
    I'm sure that it's not (signifigatly) related to the number of times I call drawImage() or anything else in my code.
    Finally, my question is:
    is there a quicker way (in platform independant implementations of Java)to draw GIF and JPG's to the screen?
    Are there any neat tricks that people use to do it quicker?
    I'd really like to keep my FPS at least at 72.
    Any help would be greatly appreciated.
    -j toyoma

    Image files themselves hold more data than what is
    actually needed for java rendering. For example, a JPG
    which is say 50K holds like 5-10K of java-useless data
    (Check on how java manages Images). The idea is to
    transform a JPG/GIF/PNG file into a custom file type
    that holds 4 bytes for each pixel: 8 bits for each R,
    G, B, and transparancy. You can probably write an
    application that opens an image file (JPG/GIF/PNG) and
    tranforms it into a row-column file of pixel data and
    then saves it as a custom file type (PixelGrabber
    could do this easily). Here is what the file might
    look like:
    WIDTH
    40
    HEIGHT
    35
    1161 2362 1545 1455.....
    1230
    1132
    992
    Each integer is a bit pattern for each pixel. ie: 1545
    as an int is:
    11000001 00100000 00000000 00000000 which is a crimson
    color. You would have to create a class that knows how
    to create an Image from this file. Dunno where you got that from, but its total garbage.
    As for the original post.
    Search this forum (and javagaming.org) for :-
    BufferStrategy,
    Managed Image,
    Automatic Image,
    VolatileImage,
    and
    createCompatibleImage.
    You will find all the answers you need with regard to performance rendering in java.

  • Tomcat6 needs more Heapsize

    I imported the application on Tomcat5.5/JDK5 to Tomcat6.0.16/JDK6.
    I did the performance test Tomcat6.0.16/JDK6.
    I got OutofMemory Error only after 10 minutes.
    As HeapSize was 256MB, I changed 512MB.
    The result was OutofMemory Error.
    Finally I found the appropriate HeapSize, 728MB.
    I did various combination.
    When I did the performance test, HeapSize wad 256MB.
    Test file is a simple JSP file.
    Tomcat5.5 + JDK 5 - baseline
    Tomcat5.5 + JDK 6 - the same performance to the baseline
    Tomcat6.0 + JDK 5 - OutofMemory Error after 10 minutes
    Tomcat6.0 + JDK 6 - OutofMemory Error after 10 minutes
    I got heapdump on Tomcat6.
    ConcurrentHashMap used 46% of Heap!!
    Was this result strange??
    Tomcat6 used java.util.concurrent.ConcurrentHashMap but Tomcat5.5 didn't.
    Tomcat5.5 called HashMap not ConcurrentHashMap.
    As StandardSesssion calls ConcurrentHashMap, I guess session object is bigger than Tomcat5.5's.
    Have you ever heard Tomcat6 needs more HeapSize compared with Tomcat5.5?

    the easy way to solve this:
    when your java program starts up, start another thread who's sole purpose is to retrieve that information and stick it somewhere.
    Then when your main program gets to the setup hopefully that information is available.
    Its especially useful if you are displaying a splash screen during startup. You can be doing your background processing (retrieving locale) info during that time.

  • Does my MacBook White 7,1 need more RAM?

    Hi, I'm Federico from Argentina.
    It's my first post here. First of all, sorry for my english, hope it's not so bad.
    I am photographer and digital retoucher, so, as you might imagine... I use a lot Photoshop (CC).
    I'm thinking that I need to upgrade my Macbook to 8gb (now I have 4gb) because my OSX is running slow, and it's affecting my workflow (upgrading to MB Pro is not a chance... no budget for that...).
    In the Activity Monitor when retouching in Photoshop memory pressure shows in yellow (Mavericks).
    Beyond that, here's my EtreCheck report, I think you may find it useful for troubleshooting my problem.
    Thank you so much!

  • Help needed with java

    Hello everyone
    I'm a Student and new to java and I have been given a question which I have to go through. I have come across a problem with one of the questions and am stuck, so I was wondering if you guys could help me out.
    here is my code so far:
    A Class that maintains Information about a book
    This might form part of a larger application such
    as a library system, for example.
    @author (your name)
    *@version (a version number or a date)*
    public class Book
    // instance variables or fields
    private String author;
    private String title;
    Set the author and title when the book object is constructed
    public Book(String bookAuthor, String bookTitle)
    author = bookAuthor;
    title = bookTitle;
    Return The name of the author.
    public String getAuthor()
    return author;
    Return The name of the title.
    public String getTitle()
    return title;
    and below are the questions that I need to complete. they just want me to add codes to my current one, but the problem is I don't know where to put them and how I should word them, if that makes sense.
    Add a further instance variable/field pages to the Book class to store the number of pages in the book.
    This should be of type int and should be set to 0 in the Constructor.
    Add a second Constructor with signature
    public Book(String bookAuthor, String bookTitle, int noPages) so it has a third parameter passed to it as well as the author and title;
    this parameter is used - obviously?? - to initialise the number of pages.
    Note: This is easiest done by making a copy of the existing Constructor and adding the parameter.
    Add a getPages() accessor method that returns the number of pages in the book.
    Add a method printDetails() to your Book class. This should print out the Author title and number of pages to the Terminal Window. It is your choice as to how the data is formatted, perhaps all on one line, perhaps on three, and with or without explanatory text. For instance you could print out in the format:
    Title: Robinson Crusoe, Author: Daniel Defoe, Pages:226
    Add a further instance variable/field refNumber() to your Book class. This stores the Library's reference number. It should be of type String and be initialised to the empty String "" in the constructor, as its initial value is not passed in as a parameter. Instead a public mutator method with the signature:
    public void setRefNumber(String ref) should be created. The body of this method should assign the value of the method parameter ref to the refNumber.
    Add a corresponding getRefNumber() accessor method to your class so you can check that the mutator works correctly
    Modify your printDetails() method to include printing the reference number of the book.
    However the method should print the reference number only if it has been set - that is the refNumber has a non-zero length.
    If it has not been set, print "ZZZ" instead.
    Hint Use a conditional statement whose test calls the length() method of the refNumber String and gives a result like:
    Title: Jane Eyre, Author: Charlotte Bronte, Pages:226, RefNo: CB479 or, if the reference number is not set:
    Title: Robinson Crusoe, Author: Daniel Defoe, Pages:347, RefNo: ZZZ
    Modify your setRefNumber() method so that it sets the refNumber field only if the parameter is a string of at least three characters. If it is less than three, then print an error message (which must contain the word error) and leave the field unchanged
    Add a further integer variable/field borrowed to the Book class, to keep a count of the number of times a book has been borrowed. It should (obviously??) be set to 0 in the constructor.
    Add a mutator method borrow() to the class. This should increment (add 1 to) the value of borrowed each time it is called.
    Include an accessor method getBorrowed() that returns the value of borrowed
    Modify Print Details so that it includes the value of the borrowed field along with some explanatory text
    PS. sorry it looks so messey

    1. In the future, please use a more meaningful subject. "Help needed with java" contains no information. The very fact that you're posting here tells us you need help with Java. The point of the subject is to give the forum an idea of what kind of problem you're having, so that individuals can decide if they're interested and qualified to help.
    2. You need to ask a specific question. If you have no idea where to start, then start here: [http://home.earthlink.net/~patricia_shanahan/beginner.html]
    3. When you post code, use code tags. Copy the code from the original source in your editor (NOT from an earlier post here, where it will already have lost all formatting), paste it in here, highlight it, and click the CODE button.

  • How large of a hard drive can I install on dual G5, and do I need more RAM?

    I recently had a situation in which my dual-processor 2.0 G5 was completely refurbished by Apple repair-new logic board, both processors, video card, thermistor, all new. Finally it has been working well after a month of trips back and forth from the Apple store. I have two internal hard drives installed on my G5, both 300GB, one for OS applications, and one for audio. I am running out of space on my main hard drive, and so I recently purchased a Maxtor 1TB hard drive, now manufactured by Seagate, from Fry's. After having my G5 refurbished, I was having an issue with my Samsung 930B monitor going into sleep mode when I boot-up from a CD, but other than that G5 was working fine. I removed the main 300GB hard drive from slot #1 and put it into slot #2, from which I had removed my audio hard drive. I installed the Maxtor drive in slot #1 and reformatted it for Mac using my laptop with ATA/USB cables previously purchased for data transfer. This took about 14 hours as I used the "zeros" option. After that I hooked up the internal cables to both drives and tried to boot up from Leopard in order to install it on the Maxtor drive, but again my monitor went into to sleep mode. We went to the Apple store to try to see if there was an issue with the computer, but everything worked fine with their monitors and CD's, as well as my CD. So there is some kind of issue with my monitor, probably software as it works fine when booting up from the main hard drive, and also was fine when I did its self-test function. While at the Apple store, they installed Leopard from their hard drive which took about 30 minutes.
    My problem is this: When I arrived home, I turned on my G5, which had been set to boot from my new Maxtor drive and complete the Leopard setup process, which we had decided to do at home as it would have taken another 20 minutes in the Apple store. The G5 turned on, chimed, I got the Apple screen with the wheel, but then after that my monitor goes into sleep mode. I can hear Leopard's setup intro playing through the speakers, but the screen is in sleep mode. So I reboot holding down the option key so I can boot up from my old (300GB) main hard drive, now in slot #2. This works and the monitor screen does not go to sleep. However, as I am browsing on the web to check for issues concerning this monitor, the G5 freezes, and I get a screen with black bars with writing in them and various technical language across the screen. This happened several times after rebooting. Finally I shut the computer down. I am going to try removing the new hard drive and putting both old ones back in and see if the G5 stops crashing. I think the monitor issue is a separate issue, and I am more concerned with the crashing, as previous to the new hard drive installation the G5 was working fine, monitor fine, other than the issue when booting up from a CD. Do I need more memory? Is the 1TB hard drive too large for my dual-processor 2.0 G5 and overloading it? Would I be better off with a 500GB drive? Would appreciate advice from persons with experience in this area. Thank you.

    I have replaced my 5 year old G5 with a Mac Pro, as the G5 just had too many issues, even after replacing all major components (logic board, both processors, video card, etc.) Once I took out the 1 TB hard drive from my old G5, it stopped having the kernel panic issue. Nonetheless I had been through a lengthy repair process previous to this issue, so I didn't care to trust an older machine any longer, especially since being told by an Apple tech that the "new" parts were really just older parts stockpiled from a central location. Could be new, could be refurbished. Apple was kind enough to credit the money we had spent on the G5 repairs towards the purchase of my Mac Pro.

  • Message "to open MLBNexDefAutobahn, you need a Java SE 6 runtime. Would you like to install one now?"  I click "not now" and it pops open a second later.  It won't go away.  Help!

    I keep getting a pop up window labled Software Update saying, "To open 'MLBNexDefAutobahn,' you need a Java SE 6 runtime. Would you like to install one now?" I click on "Not Now" and it pops open again a second later.  It is not going away! Is this a Java virus? I just installed Maverick Wednesday and got a message yesterday on google that "Google would like to take over this computer"??? Please help.
    Thanks!

    This is not a virus, or any other kind of malware. Some third-party software that you have installed is repeatedly trying to open a Java process called MLBNexDefAutobahn. What that software might be, I don't know. What software do you have that this name might fit with?

  • My ipad currently only has 18% charge, i want to download ios6 but it wont let me click on the button, could this be because it needs more charge

    my ipad 3 currently has only 18% charge, ive just gone to click on the download button to download new ios 6 but its not highlighted so therfore i cant do it, is this because ipad needs more charge?

    Yes, the update takes quite a bit of time (> 1 hr for my iPad2) and will not initiate unless you have enough juice in your battery or are plugged in.

  • I am getting a warning need more space on my disk. I have checked the Console and there have been 4000 thousand messages in my system log in the last 2 days. I have emptied as many files as possible.

    Hi
    I am getting a warning on opening my mac saying I need more space as my setup disk is full.  I have emptied many files as well as my Trash.  I am planning to get an external drive for my photos, but it has been suggested that I check Console and under the system log the following message (of which they say 4000 messages have been logged in 2 days) '06/06/2014 16:08:23.341 com.apple.dynamic_pager: dynamic_pager: Need more space on the disk to enable swapping'.  This is a copy of one of the items.  It is from the system log.  I really do not think I have enough files to warrant this warning, with the exception of photos.  My storage shows 143 MB free out of 120.47. Thanks for any help.

    First off, no MacBook Air can run 10.3 or earlier.
    Secondly, are you sure you only have 143MB of storage free?  That's seriously low.  With MacBook Airs of 120 GB hard drives, or even 140 GB which is often the case when it says out of 120, you shouldn't allow your free space to go down below 20 GB.  MB is 1024 fold less than a GB.  So if you really have 143MB free on a MacBook Air, you are long past the minimum space you should be keeping it at, and need to start clearing a lot of space now*:

    I'm asking this thread be moved to the MacBook Air forum,a as we can't say for certain what you have when you post in the 10.3 or earlier forum.

  • To open you need a Java SE 6 runtime. Why, when I have 1.7 installed?

    PREFACE: I've read most of the posts on here that discuss this issue but none have provided a real answer to this.
    I'm on Moutain Lion w/ all the latest updates from the App Store.
    I've installed Oracle's latest Java JDK (7u11) because of the recent security issue. When I go to Terminal and type in "java -version", it's the latest version of Oracle's 1.7. I don't have Apple's 1.6 version of Java on my system. I've verified that by checking in the appropriate System folder for the 1.6 JRE & JDK.
    So all seems to be fine so far and per Apple's recommendation, I'm using Oracle's latest version of Java.
    So when I go to run Charles debugging proxy, which is a Java desktop app, I get the following message in a dialog:
    "To open "Charles,” you need a Java SE 6 runtime. Would you like to install one now?"
    If I have the latest Oracle Java version installed, why am I being prompted to install Apple's 1.6 version?
    I've had this prompt in the past and went through the install before. Contrary to what another poster in another thread says, choosing install at the prompt ignores the fact that 1.7 is installed and does in fact install Apple Java 1.6. It's an outdated version of Java which I don't want on my system.
    Why do I need to install Apple's 1.6 when Oracle's Java 1.7 latest is already there?

    You would need to ask the "Charles" developer that question. There seem to be quite a few issues regarding Java 1.6 and 1.7 with the Oracle version causing the most trouble. This, of course, is not an Apple problem to solve. The Java community and Oracle need to sort out their troubles.
    You can, of course, have both versions on your system but you need to do some terminal work to switch between them. Apple has a tech support document that explains how to do that.

  • You need a java SE 6 Runtime

    I have Mountain Lion on my MacBook Pro and every time I run "Dreamweave" or "Eclipse" for example, I get this message: "To open "Eclipse" you need a java SE 6 runtime. Would you like to install it now ?".
    I've tried installing it many many times, manualy and from this notification but it doesnt work.
    I've tried installing Java 7 and tried uninstalling Java 7 then installing "Java For OSX 2013-002" and dosent work too !
    everytime I install any Java version I tried this "java -version" I got this result "No Java runtime present, requesting install." !
    anybody can help ?
    Thanks

    Contact the developers of that software for a updated 10.8.3 verison that runs off Java 7.
    They are likely working on it or perhaps something better not relying upon Java at all.
    Java is a real security nightmare lately.

  • PS CC Says I need more than 512 Vram ...

    I was using Photoshop last night just to prep a couple of photos for class submission (3 pictures, just reducing their size for web consumption), and I got the message stating that I needed more than 512 Megs of Vram, which was odd to me, as I have 1024 Dedicated available on my video card. I don't run a dual monitor setup any longer, but I do have an ASUS PBs278 that's running at 2560 X 1440. My current graphics card is an ATI Radeon 6800 HD, and my windows 7 system is running on 8 gigs of ram. Up till within the last week, CC has worked just fine, but the other day on boot, it took an unusually long time to get into the software. It eventually did, and I'm wondering if that was an update or some such that's now made the software decree that if it doesn't have the 512 it thinks it should have, the 3d functions won't happen. I don't know if it's a consequence of the larger quantity of pixels being pushed, or if it's the video card getting too old to support CC at such a high resolution now, but some help would be amazing.

    Windows 7, 64 bit. I haven't been able to replicate the error, but I have the new drivers as well. I hope this just ends up being a fluke.
