A Problem with java

I have a question with the program.I have write a program that it about polynomial which is in order to desc. But my teacher want me to modify the program to in order to asc. But I don't have any idea with that. Can anyone give me some ideas for this. How can I modify it by easy method? The code is about that,
public class Polynomial
    private int degree;
    private Node head;
    public static Polynomial addPolys(Polynomial poly1, Polynomial poly2)
        Polynomial polyRes = new Polynomial();
        int power = (poly1.degree > poly2.degree) ? poly1.degree : poly2.degree;
        while (power >= 0)
            Node n1 = poly1.head;
            while (n1 != null)
                if (n1.power == power)
                    break;
                n1 = n1.next;
            Node n2 = poly2.head;
            while (n2 != null)
                if (n2.power == power)
                    break;
                n2 = n2.next;
            if ((n1 != null) && (n2 != null))
                polyRes.addNode(n1.coeff + n2.coeff, n1.power);
            else if (n1 != null)
                polyRes.addNode(n1.coeff, n1.power);
            else if (n2 != null)
                polyRes.addNode(n2.coeff, n2.power);
            power--;
        return polyRes;       
    public void addNode(int coeff, int power)
        if (head == null)
            head = new Node(coeff, power, null);
            degree = power;
        else
            Node n = head;
            Node last = null;
            while (n != null)
                if (power > n.power)
                    if (last == null)
                        head = new Node(coeff, power, n);
                    else
                        last.next = new Node(coeff, power, n);
                    degree = power;
                    break;
                last = n;
                n = n.next;
            if (n == null)
                last.next = new Node(coeff, power, null);
    public class Node
        public int coeff;
        public int power;
        public Node next;
        public Node(int coeff, int power, Node next)
            this.coeff = coeff;
            this.power = power;
            this.next = next;
    public String toString()
        StringBuffer strBuf = new StringBuffer();
        Node n = head;
        while (n != null)
            if (n.coeff >= 0)
                strBuf.append("+ ").append(n.coeff);
            else
                strBuf.append("- ").append(-(n.coeff));
            if (n.power > 1)
                strBuf.append("x^").append(n.power);
            else if (n.power == 1)
                strBuf.append("x");
            strBuf.append("  ");
            n = n.next;
        return strBuf.toString();
}

  • Problem with Java and Windows (Mainly Vista and UAC)

    Hi all,
    I am having a problem with a program that I've devoloped. The program itself is packaged as a jar and I plan to deploy it across multiple platforms eventually however right now i am only concerned about windows based systems. I have made an installer for a windows baised systems using NSIS to install the software files. I made the installer as I need several java packages to be installed so the program would work (JAI, J3D, JAI ImageIO) and I also require the program to have fileassociations on windows.
    I know that this is not what java is about, however the majority of the users will be on windows baised systems so I've decided that OS specific installers is the best option.
    During the process I have noticed that there are several key problem with java for this type of application!
    The first issue that I have come across is getting file associations to work on java. As a .jar is not an excutable it is not possible to directly associate a filetype with it in java so to overcome this I currently run the program from a .bat files and also the program requires large memory so this also allows me to run the program with -xmx. The batch file that I use is :
    <code>
    cd PATH TO PROGRAM
    start javaw -Dsun.java2d.noddraw=true -Xmn100M -Xms500M -Xmx1000M -jar "PATH TO PROGRAM\program.jar" %1 -vram 134217728
    pause;
    </code>
    Ok so all this appears to work fine and allows windows to have file associations and start the program and thats all works perfectly but this is a non-ideal solution. Has anyone got any advice on improving this?
    The next problem that I have appears to be a problem with Vista and UAC (user access control). When a user installs the program and installs the program into the program files directory I found that the program did not work and kept saying that I did not have access to the files in the current directory. This is a problem as I read and write settings files during program execution.
    On a Vista system UAC prevents file write operations into the Program Files directory unless the program has requested elevated status even if the user is a full administrator. The probem is that there appears to be no real way to achieve this under java that I'm aware of...
    Has anyone else had this probem and has a suitable solution?
    Any advice on these issues would realy be appricated.
    Regards
    Joey

    Ok so i've kinda found a solution, its not ideal but its very good. I found this program called Elevate
    A link to the site I got it was
    http://www.wintellect.com/cs/blogs/jrobbins/archive/2007/03/27/elevate-a-process-at-the-command-line-in-vista.aspx
    This program allows you start java with a UAC dialog for high access using
    Elevate java -jar myjar.jar
    This then allows you to have full access using java... I guess it could be dangerous but it does the job.

  • Problem with java swing button and loop

    Problem with java swing button and loop
    I�m using VAJ 4.0. and I�m doing normal GUI application. I have next problem.
    I have in the same class two jswing buttons named start (ivjGStart) and stop (ivjGStop) and private static int field named Status where initial value is 0. This buttons should work something like this:
    When I click on start button it must do next:
    Start button must set disenabled and Stop button must set enabled and selected. Field status is set to 1, because this is a condition in next procedure in some loop. And then procedure named IzvajajNeprekinjeno() is invoked.
    And when I click on stop button it must do next:
    Start button must set enabled and selected and Stop button must set disenabled.
    Field status is set to 0.
    This works everything fine without loop �do .. while� inside the procedure IzvajajNeprekinjeno(). But when used this loop the start button all the time stay (like) pressed. And this means that a can�t stop my loop.
    There is java code, so you can get better picture:
    /** start button */
    public void gStart_ActionEvents() {
    try {
    ivjGStart.setEnabled(false);
    ivjGStop.setEnabled(true);
    ivjGStop.setSelected(true);
    getJTextPane1().setText("Program is running ...");
    Status = 1;
    } catch (Exception e) {}
    /** stop button */
    public void gStop_ActionEvents() {
    try {
    ivjGStart.setEnabled(true);
    ivjGStart.setSelected(true);
    ivjGStop.setEnabled(false);
    getJTextPane1().setText("Program is NOT running ...");
    Status = 0;
    } catch (Exception e) {
    /** procedure IzvajajNeprekinjeno() */
    public void IzvajajNeprekinjeno() {  //RunLoop
    try {
    int zamik = 2000; //delay
    do {
    Thread.sleep(zamik);
    PreberiDat(); //procedure
    } while (Status == 1);
    } catch (Exception e) {
    So, I'm asking what I have to do, that start button will not all the time stay pressed? Or some other aspect of solving this problem.
    Any help will be appreciated.
    Best regards,
    Tomi

    This is a multi thread problem. When you start the gui, it is running in one thread. Lets call that GUI_Thread so we know what we are talking about.
    Since java is task-based this will happen if you do like this:
    1. Button "Start" is pressed. Thread running: GUI_Thread
    2. Event gStart_ActionEvents() called. Thread running: GUI_Thread
    3. Method IzvajajNeprekinjeno() called. Thread running: GUI_Thread
    4. Sleep in method IzvajajNeprekinjeno() on thread GUI_Thread
    5. Call PreberiDat(). Thread running: GUI_Thread
    6. Check status. If == 1, go tho 4. Thread running: GUI_Thread.
    Since the method IzvajajNeprekinjeno() (what does that mean?) and the GUI is running in the same thread and the event that the Start button has thrown isn't done yet, the program will go on in the IzvajajNeprekinjeno() method forever and never let you press the Stop-button.
    What you have to do is do put either the GUI in a thread of its own or start a new thread that will do the task of the IzvajajNeprekinjeno() method.

  • I have a problem with Java and an e-procurement system integrating

    I use an e-procurement system at work and yesterday I could not get my parts list from the suppliers web site to display in our in-house eprocurment finance package.
    There is not a problem with the finance package. There is not a problem with the suppliers web site. I have verified both of these by other colleagues being able to complete what I am trying to do.
    The difference between my version of Firefox and my colleagues' is that I am on version 6.0.1 and they are on 6.0.
    I have had problems with Java not displaying certain animations on the suppliers web site but, my colleague does not and I am suspicious that this is the problem. Can anyone verify this please and what can I do about it. My Java updates are up-to-date as of yesterday and are automatic.
    Thanks.

    I was quite amazed I never got a reply to this, in the past people here have been helpful. In any case I was finally able to enter this website on the exceptions list in the Java panel, and I believe it is okay  now.

    You probably made the same mistake as I did and added the tables manually to the "sample" database instead of the "sun-appserv-samples" database.

  • Problem with Java after Software Update to 10.5.7

    Hi,
    I am facing problem with Java after having run Software upgrades.
    Here is the whole story. I recently moved to iMac 10.5.6 from PowerPc 10.4. On this new machine I was having problem running a 3rd party application, which requires JVM. As this application worked well on Tiger, I decided to upgrade JVM on my iMAC using Software Upgrade(was I insane!!). As I like my systems to be updated (as with linux on my personal machine) I clicked "install all". As a result I have the following upgrades run on my machine:
    2009-05-20 13:12:01 +0200: Installed "Mac OS X Update Combined" (10.5.7)

    Hi man,
    In the wake of this java problem I resorted to keep working on my old machine, and today in my spare time I tried to fix this new machine.
    So I execute $java on prompt, and then try to check the files it has opened, using lsof -p pid
    I see it referring to
    /System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Home/bin/java
    isn't this usually the JAVA_HOME
    However, executing $/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Home/bin/java
    hangs!!
    but
    $/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/bin/java
    works!!
    $ pwd
    /System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home/bin
    $ ./java -version
    java version "1.6.0_07"
    Java(TM) SE Runtime Environment (build 1.6.0_07-b06-153)
    Java HotSpot(TM) 64-Bit Server VM (build 1.6.0_07-b06-57, mixed mode)
    So, I changed the links as follows

    lrwxr-xr-x 1 root wheel 3 Jun 4 17:21 Current -> 1.6
    Linking my Current and CurrentJDK to 1.6 and it works!
    However, shall that be the reason!
    what is in your /Versions/Current/
    I got the following
    $ ls /System/Library/Frameworks/JavaVM.framework/Versions/Current
    CodeResources Frameworks JavaVM
    Commands Headers Resources
    There is no /Home in here, which is usually the case for /1.5 or /1.6
    Anyways, things seems to work for the moment. Lets see if I get problem with using Java.
    thanks

  • Problems with java j2re using mozilla

    Hi,
    i'm using j2re1.4.2_05 plugin for mozilla in linux (Fedora Core 2). My internet access goes throught a router (SMC Networks ISDN Barricade SMC7301TA). It's settings can be edited throught a web browser LAN connection. And here the problems begin. On routers settings page a java output console (for error and other messages) is running, which doesn't work, despite java applications on other web pages work well (I tested it on sun's java test page and it's working properly). Java console exits the following errorr message:
    >
    load: class DynamicTable.class not found.
    java.lang.ClassNotFoundException: DynamicTable.class

         ... 10 more
    Is there a way to fix this problem? Cause without the command output it's mearly unpossible to configure the router.

    Yes i can make changes. Not everything is realised with java, just the output console, which reports if the changes i made succeded, prints out logs, gives additional info about some settings etc. So, i can make changes, but i have no response, for example: everytime i save something i don't know if the save was succesful. I can't take a look at IP routing table and DHCP configuration...
    On windows xp, using internet explorer (the default version for xp) everything works perfect. But mozilla for windows has also problems with java. I know i can still change settings on wins, but right now i'm having some problems with networking on linux and i have to set things up in it (besides i use wins only because of school purposes).

  • Problems with Java SE6

    Hi. My system is updated (Mac OS X version 10.6.8) but I can not use Java.
    I have enabled "applet plug-in...." in Java preferences - and have seen this
    message on the Java site:
    Java for Mac
    Check your version of Mac OS X. » How do I find my Mac OS X version?
    Mac OS X Version 10.6 and below
    Use Software Update available on the Apple menu to check that you have the most up-to-date version of Java 6 for your Mac. Java 7 is not supported by these older versions of Mac OS X. If you have problems with Java 6, contact Apple Technical Support. Java.com does not provide a download for these systems.
    Mac OS X Version 10.7.3 (Lion) or newer
    Java 7 can run on your Mac. Java 7 requires an Intel-based Mac running Mac OS X 10.7.3 (Lion) or later and administrator privileges for installation.
    » Information about installing and using Java 7 on Mac
    - so must I contact Apple technical support - Java does not supply download for my system?  Am very confused.
    Hope somebody can help

    Apple barred Java from running on Macs in order to safeguard users by blocking Java 7 Update 11 and adding it to the banned list in XProtect.
    This was the second time in two weeks that Apple had blocked Oracle's code from running on Macs. The threat was so serious that the U.S. Department of Homeland Security had recommended that all Java 7 users disable or uninstall the software until a patch was issued. This time Java is blocked through Apple's XProtect anti-malware feature.
    Java has come under fire as the means by which hackers have been able to gain control of computers. In April 2012 more than 600,000 Macs were reported to have been infected with a Flashback Trojan horse that was being installed on people's computers with the help of Java exploits. Then in August Macs were again at risk due to a flaw in Java, this time around, there was good news for Mac users: Thanks to changes Apple has made, most of us were safe from the threat.
    Unwilling to leave its customers open to potential threats Apple decided it's safer to block Java entirely.
    In order to block older versions of Flash, Apple has updated its "Xprotect.plist" file so that any versions that come before the current one (version 11.6.602.171) cannot be used on a Mac. Users who have older versions of Flash installed will be greeted with an alert that says "Blocked plug-in," and Safari will prompt the user to update to a newer version.
    Macs running OS X Snow Leopard and beyond are affected.
    UPDATE for those running Lion or Mountain Lion:
    Oracle on Friday February 1 released a new version reportedly addressing vulnerabilities seen with the last build.
    Apple disabled Java 7 through the OS X XProtect anti-malware system, requiring users to have at least version "1.7.0_10-b19" installed on their Macs. The release dated February 1 carries the designation "1.7.0_13-b20," meeting Apple's requirements.
    Oracle "strongly recommends" applying the CPU fixes as soon as possible, saying that the latest Critical Patch Update contains 50 new security fixes across all Jave SE products.
    Update for Snow Leopard users:
    Apple issued update 12 for Java for OS 10.6:
    http://support.apple.com/kb/DL1573
    Note:  On systems that have not already installed Java for Mac OS X 10.6 update 9 or later, this update will configure web browsers to not automatically run Java applets. Java applets may be re-enabled by clicking the region labeled "Inactive plug-in" on a web page. If no applets have been run for an extended period of time, the Java web plug-in will deactivate.
    If, after installing Java for OS X 2013-002 and the latest version of Java 7 from Oracle, you want to disable Java 7 and re-enable the Apple-provided Java SE 6 web plug-in and Web Start functionality, follow these steps:
    http://support.apple.com/kb/HT5559?viewlocale=en_US
    Further update:
    Apple issued this Java related security update No. 13 on February 19:
    http://support.apple.com/kb/HT5666
    and Update No. 14 on March 4:  http://support.apple.com/kb/DL1573
    http://support.apple.com/kb/HT5677
    You should also read this:
    https://support.apple.com/kb/HT5672
    The standard recommendation is for users to turn off Java except when they have to use it on known and trusted websites (like their bank). Javascript, which is unrelated despite the name, can be left on.

  • Problems with Java on Macbook Air OS X 10.6.8

    I have a MacBook Air OS X 10.6.8 and need to use Java to download an App for online tutorials - 'Elluminate'.  Unfortunately I can't seem to download this app due to problems with Java.  I have made various attemps to download Java 6, software update and altered web browsers but nothing has worked.  There is no java icon in my systems preferences and only 'java preferences in my applications.  I need Elluminate to be working by Tuesday - any advice would be appreciated!!

  • Problems with java logging utility

    Hi,
    I am having a few problems with java's logging framework.
    When I create a logger using
    Logger log = Logger.getLogger("my.com");
    and log my messages using this "log" object, the messages are logged to System.err which is my console. But when I add a Filehandler to this Logger object, I get log messages both in the file and the standard error.
    The problem is that I want to supress logging to the standard error but do not know how to do this. I tried a few things:
    1) If I close the standard error (System.err.close() ), things work fine but I can't afford doing this since other parts of my application might use System.err for some purpose.
    2) I thought that , by default, a ConsoleHandler object is added to the Logger object. So I thought I might get around the problem if I close() this ConsoleHandler object. But, to my surprise, log.getHandlers() returns an empty array by default. So there is no ConsoleHandler attached to it.
    Any info. regarding it will be very much appreciated.
    Thanks,
    Arch.

    Logger.setUseParentHandlers(false)

  • Problems with Java AQ interface migrating 9i to 10g

    Hi!
    I've got problems with Java AQ Interface migrating from 9i DB, JDBC, AQ to 10g rel.2 DB, JDBC, AQ
    First, i started to occasionally receive NullPointerException in Oracle JDBC 9.2.0.8
    java.lang.NullPointerException

    We were using 9.2.0.8 JDBC and 9i and 10g databases.
    We decided to go up for 10g r2 JDBC Drivers, and 10.2 AQ but started to get the following errors:

    Can anyone help?
