Change the value of "int" one within the arraylist class instance.

It's my program...

-Hello.java

public class Hello {}

public int a = 5;
public char c = 'A ';
}

-Main.java-

public class Main {}

ArrayList < Hello > Hello = new ArrayList < Hello > ();
Hello.Add (new Hello());

Public Shared Sub main (String [] args) {}
int b;
int c;
I'm going to get the value of "int a" in the first list of tables and store it in "int b.
b = hello.get (0) .a;

Now, I want to change the value of "int a" within the first class of the table
///////////////////////////////
WHAT SHOULD I DO...? //
//////////////////////////////

Finally, I'll get the value of "int a" and store it in "int c".
c = hello.get (0) .a;


}

}

Help, please... >! @! @~

Well, nothing of this code will compile, but if you corrected the errors, and that was the case, you can replace it with

hello.get(0).a = 123;

But what you should really do is read all the tutorials you can find.

  • Hi, is it possible to change the security class for folders that contain data forms?

    Hello

    We would like to change the class of security for a folder that contains the data forms in our application.

    This should be done on two occasions during our monthly closing.

    When I create a new folder I can assign the class of security to the folder. But how it works for an existing folder?

    Thank you very much

    To answer your question, there is no way to change the safety classes existing folder with the existing versions of HFM. We have already asked DEV as an improvement. The only solution is to remove the existing form folder and then re-create.

  • change the default MovieClip instance name

    Hello

    My problem is the result of this code:

    for (var j = 0; j < numChildren; j ++)

    {

    If (getChildAt (j) block)

    {

    blocks.push (MovieClip (getChildAt (j)));

    var tempBlock = MovieClip (getChildAt (j));

    If (tempBlock.hitTestObject (mc))

    {

    test = true;

    }

    on the other

    {

    test = false;

    }

    }

    }

    now the thing is that will have more than one block, so if one of these blocks is not the "mc" then test will be False, even if the mc is in contact with another block, and I think that this can be resolved if I can get their name (I can do than tempBlock.name) and then change my else statement (is not the problem)

    what I need is to know how to change tempBlock names using the 'j' counter what I need exactly what

    tempBlock.name = "block" + j;

    but when I did it I get this error:

    Error #2078: Cannot modify the name property of a Timeline-place object.

    Thank you

    You cannot change the name of the instance of an object placed on the stage in the authoring environment (and all set on the stage in the authoring environment has an instance name if you assign one or not).  everything that has a name property can be assigned or changed by using the name property:

    var mc:MovieClip = new MovieClip();

    MC. Name = "OriginalName";

    //

    MC. Name = "newname";

  • change the Timer class Delay time

    Is it possible to update the duration of the Timer class period while it is running. I want to update using the slider, but it seems not updated. I even stop the timer on the event cursor THUMB_PRESS that restart after his change. Doesn't seem to work that way either. Any ideas?

    I thought about it. Instead of setting a variable speed where the Manager works for the slider I directly changed the delay timer variable to equal the value of the slider. I feel stupid now, but it works very well.

  • Two quick questions (hopefully) - right way to dynamically change the CSS class and put of Splash screen implemented

    Couple of quick questions have left me speechless!

    So, it seems obvious that many JavaFX applications want to dynamically change the CSS styles.  Is the best way to do it through la.getStyleClass () .add ("classname") < node >?  The underlying data structure is a list of observable.  So let's say we have 5 styles that simply to change the fill color of a circle of 5 different colors, respectively.  So if I have a condition in which I want to dynamically apply 1 of these 5 styles, as I do now it's by setting all 5 styles as a string in a list by using a static initializer, then I call < node > .getStyleClass () .removeAll (list), then getStyleClass () .add ("classname").  I do this to avoid adding again and still the same style and inflate the underlying list.  What is the right way to manage dynamic CSS styles?

    Finally a very simple I think.  So I know there's a little differently to implement a splash screen.  My app has certainly got bigger in the last few months of development and I noticed there are about a 5 second delay between when I run the application when I see the main stage.  I was thinking what a splash screen would be nice to fill that time.  I had no time to prototype using a Preloader and I fear that using another, early stage start-up again would be too long of a delay.  "I actually thought that using the Nice and simple JVM argument" - splash: image name > "would be simple, easy and effective.  Unfortunately when I try to do, the splash screen appears but never goes away.  Anyone know what is happening with this?

    Your mechanism to manage the css style classes is a good approach; I've used several times. I wonder why the style classes have been implemented as a list, instead of a game, but there may be cases of good use for the use of a list.

    In some cases you can also consider using CSS PsuedoClasses, which were presented in JavaFX 8. Here is a little easier to use, especially if you have two options. But a use case might look like:

    public class Message {
        public enum Status { NORMAL, WARNING, CRITICAL }
    
        private final ObjectProperty status = new SimpleObjectProperty<>(Status.NORMAL);
        private final StringProperty message = new SimpleStringProperty();
    
        // constructor, getters, setters, and property accessors....
    }
    
    public Label createLabel(Message message) {
        PseudoClass warning = PseudoClass.getPseudoClass("warning");
        PseudoClass critical = PseudoClass.getPseudoClass("critical");
    
        Label label = new Label();
        label.textProperty().bind(message.messageProperty());
        message.statusProperty().addListener((obs, oldStatus, newStatus) -> {
            label.pseudoClassStateChanged(warning, newStatus == Message.Status.WARNING);
            label.pseudoClassStateChanged(critical, newStatus == Message.Status.CRITICAL);
        }
        return label ;
    }
    

    And then your css looks like

    .label:warning {
        -fx-text-fill: orange ;
    }
    .label:critical {
        -fx-text-fill: red ;
    }

    Hello

    I think that the best approach I've seen so far is to retrieve all documents via LCM (SSP), edit Web Forms with a text editor which can edit multiple files in the same file (Notepad ++) and then reload via LCM webforms.

    Nope, search and replace is the way to do it. You can do this easily by assigning the class research specific [any tag] tag with the attribute = class to set the attribute oldname to newname. Set this Site current Local, then click on replace all.

  • To access the upper class instance variables

    Hello

    See the code provided below. If home * variable 'i' is not set to 4, the output will be 3, if it is set, it will be 4.
    My question is... Well, I don't know exactly, there would be a lot. All this is strange to me.
    (For example, it seems that for the super class constructor runs when I access an instance of her variable).
    Could someone explain this topic or maybe help me to direct to an article?
    public class TryThis {
        
        public static void main (String args[]){
    
             Child c = new Child();

    Note: Parent could also simply look like this:

    }

    I see now that it is wrong to use the word 'object '.

    No, it isn't.

    they are there for the child to use, object

    That's where you're going wrong. Don't think about "the parent" and "child object. There is only one object, and it is mentioned by "this". You should think about members of the base or the classes and members of the (current) derived class. They are all members of the 'object', but the members of the base class can be hidden by the current members of class with the same name. That's all. Nothing too special about it.

    but they aren't the fields of it.

    Yes they are, but if they are hidden by local declarations that they are not visible to 'this', only to 'super '.

  • You cannot change the security log class

    If a journal has been posted on entity and calculations/consolidations run on this entity, it is not possible to change the security of this journal class (after unposting of course).

    Is this a bug or a feature? ;-)

    UPDATE. Contacted support, showed the problem, conclusion by Oracle - not a bug, the expected features

    11.1.2.2 reviews open in a separate tab. The problem occurs when user unposts the journal button unpost in this tab and then try to change the security class. All in the same tab without closing. Apparently, the only way to make it work is unpost the journal directly on the tab manage reviews, and then only open a separate tab with the newspaper which has already the Unposted status. Otherwise, open the log unpost tab, close tab, open it again, change the class of security

    I said in support of Oracle who struck me really helped understand the problem, but still it is a bit silly and could be improved in the future. Wonder if they would take it into consideration...

    Thank you all,

  • Using the PrintJob class

    Hi all

    I am new to AS3 and was never as competent to AS2. I'm working on a simple drag and drop coin and I want to be able to print the contents of the operation drag / move.

    I try to use the PrintJob class that comes with CS4, but his does not work.

    Here's what I have...

    THE BUTTON MANAGER

    ActionScript code:
    print_btn.addEventListener(MouseEvent.CLICK,printContent);

    function printContent(evt:MouseEvent) {
        var printJob:PrintJob = new PrintJob();

        if (printJob.start()) {

            if (content_MC.width>printJob.pageWidth) {
                content_MC.width=printJob.pageWidth;
                content_MC.scaleY=content_MC.scaleX;
            }

            printJob.addPage(content_MC);
            printJob.send();
        }
    }

    THE PrintJob CLASS INCLUDED IN CS4

    ActionScript code:
    //****************************************************************************
    // ActionScript Standard Library
    // PrintJob object
    //****************************************************************************

    intrinsic class PrintJob
    {
        var orientation:String;
        var pageHeight:Number;
        var pageWidth:Number;
        var paperHeight:Number;
        var paperWidth:Number;

        function PrintJob();

        function addPage(target:Object, printArea:Object, options:Object, frameNum:Number):Boolean;
        function send():Void;
        function start():Boolean;
    }

    I get all sorts of errors, prompting me to change the PrintJob class. But as soon as I make an edit he comes up with an error after another one will not work.

    What I'm missing here? The PrintJob CS4 class should not just be straight out of the box? Sorry if this is such a newbie question. But I'm a newbie!

    Any help would be greatly appreciated.

    Thanks in advance!

    You are welcome.

  • changing the value of text within a column of a PivotTable

    Hi people,

    I get great help from this forum and I am very frequently. This time, I have a question about Tables, how to manipulate fields in a table using JavaScript. The requirement is as follows, I have a Table (100rows x 3columns), and few of them are hidden in the page layout. The first column contains the values of text such as sequential numbers, (the first column is visual index, 1, 2, 3... 100). now, I'm trying to write a script that replaces or substitutes the first column values in the text areas of space. Can you guys help out me if you do a script? or give me some resources where I can manipulate the fields from the table using JavaScript?

    Thanks in advance.

    Hello

    It seems that the table is static and will always three rows during execution. In other words, the user cannot add more lines. If this correct?

    You need not resolve the nodes in this case, because you are referencing fields and specific lines.

    Because the script is located in the square, which is in the same container as the table, the following would erase the contents of the fields in the second column:

    Table1.Row1[1].TextField3.rawValue = null;
    

    Your script accesses an object in the second row called Cell1. This seems to be a text object has no property .rawValue If you want to change the value at run time, you will need to change this to a TextField object.

    In addition, looks like that is not an object in the second row (Row1 [1]) called "Cell1". It seems that the first object is unnamed. This will also cause the script to fail. When debugging, it is useful to use the JavaScript Console to see the (control + J) errors when previewing the form or in Acrobat.

    Who help me?

  • Is it possible to change the values of particular #define of the various controls in CVI.

    In my application, I have different panels to file single .uir. When I save the .uir file, I get the same values of #define for different controls in different panels. For this reason, I am not able to use these #defines block switch. Is it possible to change the values of #define according to my condition.

    Hi, a little more Wolfgang post. It is the combination of the Panel to manage and control the unique ID: as you know, you can load the same panel more than once, so even if you recover the full chain of PANEL_CONTROL you have duplication. items that exactly identifies a particular control in a particular group are the combination control panel manage AND panel_control ID.

    On the one hand which guarantees more flexibility to your application, you can design only a few panels and reuse them whenever you want, even having some of them loded several times in the same instant. On the other hand, as you have discovered, there is the possibility (Finally, almost certain) duplicated in your app ID.

    To resolve the problem of duplicated IDS you can act in two ways:

    1. If you know that no Panel is never loaded several timer in your application, you can retrieve the name of constant of Panel with GetPanelAttribute (panelHandle, ATTR_CONSTANT_NAME, string); and to distinguish between the name of constant, then switch between control ID

    2. If you happen to have duplicate panels you will need to store each panelHandles in the non-volatile variables, switch between them and then switch between the control ID

    An alternative might be to use Panel callbackData attribute and assign a significant value during the loading of the Panel, other callbackData finally from a control ID. Something like this:

    Loading panels:

    panelHandle = LoadPanel (0, "myfile.uir", PANEL1);

    SetPanelAttribute (panelHandle, ATTR_CALLBACK_DATA, (void *) 1);   Assign different callbackData in each instance

    During the failover between controls:

    void * cbkd;

    GetPanelAttribute (panelHandle, ATTR_CALLBACK_DATA, &cbkd);)
    Switch (cbkd (int)) {}
    case 1: / / elements of the PANEL1
    switch (command) {}
    case PANEL1_NUMERIC:

    your code here
    break;
    case PANEL1_STRING:
    your code here
    break;
    }
    break;
    case 2:
    // .....
    break;
    }

    One final note: it seems to me that all this is necessary in a very limited situation, where you have the same callback called on various panels/controls. Whenever the reminder is unique to a specific panel or controls on a single panel you don't need to work that way.

    Section 3:
