     thats my code and the program is supposed to open a text file called "Omerta" and edit it so that it takes out all the double spaces between the words in the text file...ive been told that this should work.......yet i still am unsucessful in compiling the code....all help will be greatfully appreciated

ive been told that this should workThe replies to your earlier posting here:
http://forum.java.sun.com/thread.jspa?threadID=573173&messageID=2844611#2844611
did not tell you that, they told you what was wrong - and is still wrong. And, in addition, you have introduced another error in your curly braces.
You need to understand how to construct a Java class; see this tutorial:

  • Need help with threads?.. please check my approach!!

    Hello frnds,
    I am trying to write a program.. who monitors my external tool.. please check my way of doing it.. as whenever i write programs having thread.. i end up goosy.. :(
    first let me tell.. what I want from program.. I have to start an external tool.. on separate thread.. (as it takes some time).. then it takes some arguments(3 arguments).. from file.. so i read the file.. and have to run tool.. continously.. until there are arguments left.. in file.. or.. user has stopped it by pressing STOP button..
    I have to put a marker in file too.. so that.. if program started again.. file is read from marker postion.. !!
    Hope I make clear.. what am trying to do!!
    My approach is like..
    1. Have two buttons.. START and STOP on Frame..
    START--> pressed
    2. check marker("$" sign.. placed in beginning of file during start).. on file..
         read File from marker.. got 3 arg.. pass it to tool.. and run it.. (on separate thread).. put marker.. (for next reading)
         Step 2.. continously..
    3. STOP--> pressed
         until last thread.. stops.. keep running the tool.. and when last thread stops.. stop reading any more arguments..
    Question is:
    1. Should i read file again and again.. ?.. or read it once after "$" sign.. store data in array.. and once stopped pressed.. read file again.. and put marker ("$" sign) at last read line..
    2. how should i know when my thread has stopped.. so I start tool again??.. am totally confused.. !!
    please modify my approach.. if u find anything odd..
    Thanks a lot in advance

    Hello,
    I have no experience with threads or with having more than run "program" in a single java file. All my java files have the same structure. This master.java looks something like this:
    ---master.java---------------------------------------------------
    import java.sql.*;
    import...
    public class Master {
    public static void main(String args []) throws SQLException, IOException {
    //create connection pool here
    while (true) { // start loop here (each loop takes about five minutes)
    // set values of variables
    // select a slave process to run (from a list of slave programs)
    execute selected slave program
    // check for loop exit value
    } // end while loop
    System.out.println("Program Complete");
    } catch (Exception e) {
    System.out.println("Error: " + e);
    } finally {
    if (rSet1 != null)
    try { rSet1.close(); } catch( SQLException ignore ) { /* ignored */ }
    connection.close();
    -------end master.java--------------------------------------------------------
    This master.java program will run continuously for days or weeks, each time through the loop starting another slave process which runs for five minutes to up to an hour, which means there may be ten to twenty of these slave processes running simultaneously.
    I believe threads is the best way to do this, but I don't know where to locate these slave programs: either inside the master.java program or separate slave.java files? I will need help with either method.
    Your help is greatly appreciated. Thank you.

  • Need help with flash player installation please !!!!

    Hello,
    I need help with my flash player installation because every time I access a movie this is the message I receive. 
    This content on Xfinity TV is not available for viewing with Chrome's "Incognito" mode. To play this video using Chrome, please view this page without "Incognito" mode.
    Still having problems? Try resetting your Flash player license.

    Incognito mode is a Google Chrome setting when you open a new window (Cmd+Shift+N on a Mac Ctrl+Shift+N on Windows) It opens a "private" window with no cookies and no tracking. The problem with it is that when you disable cookies, your license files are not sent to the site (whetehr it's YouTube or xFinity or any other that uses license files for paid content)  and it treats you as if you're a first time visitor. Paid videos won't play wihtout the cookies sending the license file info.
    This isn't a Flash Player setting. It's in Chrome. I did some research and according to Google, "Incignito" mode is off by default, and can ONLY be activate by the keyboard shortcut. There IS a way to disable it from the registry http://dev.chromium.org/administrators/policy-list-3#IncognitoModeAvailability

  • Need help with trim and null function

    Hi all,
    I need help with a query. I use the trim function to get the first three characters of a string. How do I write my query so if a null value occurs in combination with my trim to say 'Null' in my results?
    Thanks

    Hi,
    Thanks for the reply. What am I doing wrong?
    SELECT trim(SUBSTR(AL1.user_data_text,1,3)),NVL
    (AL1.user_data_text,'XX')
    FROM Table
    I want the XX to appear in the same column as the
    trim.The main thing you're doing wrong is not formatting your code. The solution may become obvious if you do.
    What you're saying is:
    SELECT  trim ( SUBSTR (AL1.user_data_text, 1, 3))
    ,       NVL ( AL1.user_data_text, 'XX' )
    FROM    Tablewhich makes it clear that you're SELECTing two columns, when you only want to have one.
    If you want that column to be exactly like the first column you're currently SELECTing, except that when that column is NULL you want it to be 'XX', then you have to apply NVL to that column, like this:
    SELECT  NVL ( trim ( SUBSTR (AL1.user_data_text, 1, 3))
                , 'XX'
    FROM    Table

  • New to Java and need help with this program..please!

    I'd really appreciate any helpful comments about this program assignment that I have to turn in a week from Friday. I'm taking a class one night a week and completely new to Java. I'd ask my professor for help, but we can't call him during the week and he never answers e-mails. He didn't tell us how to call from other classes yet, and I just can't get the darn thing to do what I want it to do!
    The assignment requirements are:
    1. Change a card game application that draws two cards
    and the higher card wins, to a Blackjack application
    2. Include a new class called Hand
    3. The Hand class should record the number of draws
    4. The application should prompt for a number of draws
    5. The game is played against the Dealer
    6. The dealer always draws a card if the dealer's hand total is <= 17
    7. Prompt the player after each hand if he wants to quit
    8. Display the total games won by the dealer and total and the total games wond by the player after each hand
    9. Display all of the dealer's and player's cards at the
    end of each hand
    10. Player has the option of drawing an additional card after the first two cards
    11. The Ace can have a value of 11 or 1
    (Even though it's not called for in the requirements, I would like to be able to let the Ace have a value of 1 or an 11)
    The following is my code with some comments about a few things that are driving me nuts:

    Thank you so much for offering to help me with this Jamie! When I tried to call change value using:
    Card dealer = (d.changeValue());
    I get an error message saying:
    Incompatible types found: int
    required: Card
    I had my weekly class last night and the professor cleared up a few things for me, but I've not had time to make all of the necessary changes. I did find out how toString worked, so that's one question out of the way, and he gave us a lot of information for adding another class to generate random numbers.
    Again, thank you so much. I really want to learn this but I'm feeling so stupid right now. Any help you can give me about the above error message would be appreciated.

  • I just bought my MacBook Pro 13" and I tried to install an anti virus but then it went into a grey folder with a question mark I need help with restoring the iOS please

    I need help taking out the grey folder with the question mark and I've try everything except the CD thing because my MacBook didn't come with one so I really need help please

    What anti-virus software did you install? Although there's a lot of bad anti-virus software out there, no anti-virus software should cause such a problem. A gray screen with a flashing question mark on a folder means that no bootable system could be found, which means that the system was badly damaged or corrupt. Even installing bad software would not normally cause that, so either there was something badly wrong with the system already or the anti-virus software you tried to install was really, really bad!
    As mende1 says, you need to reinstall the system at this point. After your system is back up and running, read my Mac Malware Guide. If, after reading that, you want anti-virus software, use one of the programms recommended in that guide.

  • Need help with icloud activation lock please

    hi firends
    i have be dragged by apple for last 3 weeks or so i had purchased a device in new zealand with orignal proof of purchase submitted to apple icloud team and the best part is they re validate it with the pervious owner and got the same copy if purchase from them when i try to call them up they said they have submitted to the concern department for unlocking and yesterday i get an email saying they cant do it as the shop who sold in new zealand has bought it from USA and now they need the receipt from there to make it work where all legal check up was done and everything is crystal clear APPLE IS JUST HARASSING me for no reason this why people now do want to promote APPLE when a genuine case is presented to them with complete info from seller to buyer and all documents they not ready to unlock it. i highly request every one to please raise this type of concern and get this one voice to TIM COOK AND HIS TEAMthat why genuine person are being left behind where the same icloud can be unlocked by paying to hackers who help people like us to trust them more then APPLE.

    How the lock works is explained by Find My iPhone Activation Lock and Find My iPhone Activation Lock: Removing a device from a previous owner's account.
    On YouTube you will find some videos helping bypassing the lock and get access to the contacts. With some luck you can contact the previous owner and force him to remove the iPhone from the devices list at icloud.com/find.

  • Need help with blown out highlights please

    Hi.  I am not very good with Photoshop and need some help on how to fix the blown out highlight areas of this photo, please.  I've spent the past couple of hours trying to figure this out and have not found a good technique yet.  Any help will be most appreciated.

    First brighten the shot up using an adjustment layer and then brush your highlights back to where they are now. the fact your shot looks so dark,makes the bright areas more noticeable. if they are totally blown in the original,you cant get detail where it does not exist, but making the overall image brighter visually should help in my opinion.

  • Need help with GetStringUTFChars and JAB

    Please help,
    I want to use the JNI function GetStringUTFChars with JAB (Java Access Bridge), without having to call JNI_CreateJavaVM as no matter what I do, JNI_CreateJavaVM fails. I have JAB successfully loaded, and I have used GetAccesibleFromHWND to get a valid jobect. Is there any way I can go from the jobect to use GetStringUTFChars?
    If not, is the source code availabe for GetStringUTFChars? OR is there an Windows/C++ equivalent available?

  • I am a rookie and need help with max and min values

    Hello all, i am into this intro to java class. my assignment is to write a program that prompts the user for two integers and then prints the sum, difference, average, product , distance (absolute value of the difference) Maximum(largest of the two) and Minimum(smallest fo the two) here is my code so far
    import java.io.BufferedReader;
    import java.io.IOException;
    import java.io.InputStreamReader;
    import java.lang.Math;
    public class Sample4
       public static void main(String[] args) throws IOException
          try // attempt the following
    {           // create the stream to read from
    InputStreamReader istream = new InputStreamReader(System.in);   // create a buffer to hold the stream
    BufferedReader console = new BufferedReader(istream);           // prompt the user
          System.out.println("Enter a number please");              // get input as a string
          String input = console.readLine();                        // convert to an integer
          int num1 = Integer.parseInt(input);
          System.out.println("Enter a number please");              // get input as a string
          String input2 = console.readLine();                       // convert to an integer
          int num2 = Integer.parseInt(input2);
          int sum = num1 + num2;                                    // get the sum of the two inputs
          int difference = num1 - num2;                             // get the difference of the two inputs
          int product = num1 * num2;                                // get the product of the two inputs
          int average = sum / 2;                                    // get the average of the two inputs
          int abs = Math.abs(difference);                           // get the absolute value of the two inputs
              // new section
                 // display the number
          System.out.println("The total sum = " + sum);
          System.out.println("The total difference = " + difference);
           System.out.println("The total product = " + product);
           System.out.println("The total average = " + average);
           System.out.println("The total absolute value = " + abs);
    } // if something breaks, catch the exception
    catch (IOException e)
       System.out.println(e); // displays the exception
       System.exit(1);  // quits the program
    }what will be the right syntax or code to find the MAX and MIN values of two numbers a User Inputs, hope someone can help with this. thank you for your help.

    Thanks alot man, sheesh i do not know why my book
    doesnt give me all the static methods. but i do really
    appreciate your help. peaceA complete list of the java.lang.Math methods can be found at http://java.sun.com/j2se/1.4/docs/api/java/lang/Math.html
    btw,
    max(a, b) == (a > b) ? a : b
    min(a, b) == (a < b) ? a : b
