Extending Math class

As I understand, in actionscript 2 you could extend flash's Math class to add your own functions, but this is no longer possible in actionscript 3. I want to add a mod() function to the Math class, and I'm assuming I have to write a wrapper class to accomplish this. How do I import the existing Math class into my MathPlus or whatever class? Also, is there anything else I should know about this?

Thanks for the replies (very good to know about %). The only reason I would prefer to extend Math or build a wrapper around it is if I were to write a sufficient number of additions such that trying to remember which were in Math and which were in my custom class became difficult. I just think it would be nice to have access to all of my (and Flash's) math related code within one class.
It just occurs to me that I just need to make functions in my class that call the ones in Math.

Good extended math + utility class

It has proved surprisingly difficult to find a free "extended" math class for java - all I'm after is a utility class with things like erf, cosh, sinh... things that java.lang.Math lacks.
I must be doing something wrong, but if some altruistic person could point me in the right direction, I'd be grateful. :)

this might be even more useless to you, hehe. but you can have a look anyway:

Why Math class does not have any constructor.

Math class does not have any constructor.
But all the classes have a default constructor. Then why the math class is not having any constructor. Is math class having some other constructor or is the default constructor concept applicable only for user defined classes.

Java Math Class

Looking for a math class method to calculate prime numbers up to 1000 and also perfect numbers up to 1000. Anybody know if one is available ?

You can try the following if you think it might help:public class MyMaths extends Homework {
    public static int[] primesUpToN(int n) {
        researchTopics.add("Eratosthenes' Sieve");
        researchTopics.add("Prime Numbers");
        addKnowledge(researchTopics.performResearch());
        Algorithm al = codeAlgorithm(knowledge, skills, resources);
        while (!al.testsSuccessful()) {
            Bug bug = al.debug().getNextBug();
            bug.quash();
        return al.apply(n);
    public static void main(String[] args) {
        System.out.println(primesUpToN(1000));

?Is it possible to create a javafx class without extending Application class ? If yes, how

Is it possible to create a javafx class without extending Application class ? If yes, how ?

There is no such thing as a javafx class. It is a regular java class. The Aapplication class is the entry
point for JavaFX application. You have to extend the Application class to create Javafx application .

LoadClass (error loading a class which extends other class at run-time)

Hey!
I'm using the Reflection API
I load a class called 'SubClass' which exists in a directory called 'subdir' at run-time from my program
CustomClassLoader loader = new CustomClassLoader();
Class classRef = loader.loadClass("SubClass");
class CustomClassLoader extends ClassLoader. I have defined 'findClass(String className)' method in CustomClassLoader.
This is what 'findClass(String className)' returns:
defineClass (className,byteArray,0,byteArray.length);
'byteArray' is of type byte[] and has the contents of subdir/SubClass.
the problem:
The program runs fine if SubClass does not extend any class.
If however, SubClass extends another class, the program throws a NoClassDefFoundError. How is it conceptually different?
Help appreciated in Advance..
Thanks!

Because i'm a newbie to the Reflection thing, i'm notI don't see reflection anywhere. All I see is class loading.
sure what role does the superclass play when i'm
trying to load the derived class and how to get away
with the errorWell... hint: all the superclass's stuff is not copied into the subclass.
I am quite sure it fails to load the superclass because of classpath issues.

Error while extending controller: class name is wrong or not included

Hi All,
I am getting this error while I port my extended controller class to the custom top and assign this controller to the page. I have made sure its the class file that is copied. The directory is correct, the permissions were given using chmod 775. There exists a soft link betwen the custom top and the oracle top as well. What else am I missing here?
Error: oracle.apps.fnd.framework.OAException: Could not create Java class: (oracle.apps.ap.oie.entry.webui.XXEntryFlowPageCO) associated with region: (GeneralInformationPG). This is probably because the class name is wrong or not included in project.

:( Started out with that Gyan. If i do give the path with xx. appended to it, it lets me save and when i log back in and there are no changes to the page. I go to the personalise option to find the modification has been overwritten. I was told that this is so because Oracle doesnt recognise the xx.path and since there exists a soft link already the standard path with the new controller name should work.
i have really tried both of these options and am not sure what could be wrong. thanks for all your attempts to help. anything else i can try?

Java ME SDK 3.0 Math Class

Using Eclipse and Java ME SDK 3.0
When the Application Descriptor configuration is set to use DefaultCldcPhone1 or other emulators in the Java ME SDK 3.0 many of the Math class methods such as Math.sqrt(double arg0) are not available. However if I change the configuration to use a Nokia emulator all the Math class methods become available.
This issue has just shown up since moving from WTK25 to Java ME SDK 3.0
Note:
Under Eclipse/Preferences/Java ME/Device Management the Configuration of all the emulators from the Java ME SDK 3.0 is listed as CLDC-1.0 whereas the other emulators from Nokia and from the Sun Java Wireless Toolkit 2.5 are listed as CLDC-1.1.

It is related to the configuration of the emulator (CLDC 1.0 or CLDC 1.1)...
If the configuration is CLDC 1.0 all the floating point data types (float, double, Float, Double) will not be available...
If you change the configuration to CLDC1.1 , then all the previous types will be available.
PS: I don't know how to do this in EclipseME

Loading external swfs extending from classes in the same shared codebase

Hey there!
I'm currently developing a game in flash and want to be able to divide up my .fla assets in a way that means artists can work on a game menu .fla in isolation from the game.fla and rest of the game code.
If I could briefly explain how I've approached this so far, I would be extremely if people could shout in my general direction and tell me I am stupid, or even better still, give me helpful advice as to where I am going wrong and how I can correct it!
My project is setup like this:
HighScoreMenu.fla -> document class HighScoreMenu extending GameMenu class.
game.fla ->document class game.as
game.as class loads the published HighScoreMenu.swf and manipulates the menu i.e. animates on and off screen via inherited functions in the GameMenu class.
Now this seemed to work to begin with, until my code evolved and upon going to publish my HighScoreMenu.fla flash started complaining about symbols being used in Game.as that were in Game.fla... If I'm only publishing the HighScoreMenu which extends from GameMenu then why is it even looking to compile Game.as?
Can you spot the problem in the way I am doing this, or is there a better approach I should try?
Any advice greatly appreciated!
Stevie.

No it doesn't seem to, however though they both have a reference to the HighScoreManager so there is some overlap there between menu and game code, but the menu classes don't reference any symbols on the game.fla...
Just to clarify, I have an fla HighScoreMenu.fla, which has a child symbol HighScoreMenu which uses the following class.
public dynamic class HighScoreMenu extends GameMenu
//convenient storage for competition Manager object
private var _highScoreManager:HighScoreManager;
The game then loads this class as follows:
I load the swf "HighScoreMenu.swf" and once its loaded I obtain the menu class like so:
var cls:Class = Class( applicationDomain.getDefinition("Menus.HighScoreMenu") );
var object:* = new cls();
...and create a new instance of the menu.
Is there anything fundamentally wrong with approaching it in this way?

Not able to pass values to variables in extended Tree class

Hi,
I have a as class that extends from Tree, additionally this
custom class defines
new class level variables as follows:
public class MyTree extends Tree {
public var arrayColl:ArrayCollection;
and i call this tree from mxml as follows:
<customTree:MyTree
arrayColl={list}
xmlns:customTree="../../.*"/>
Though my 'list' collections is not null, when i place an
alert in the constructor of extended tree class
it shows as null.
Please advice.
Thanks,
Lucky

below is the canvas:
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="

</customTree:MyTree>
</mx:HBox>
</mx:VBox>
</mx:Canvas>
The collection of TreeData is iterated in the customTree to
form xml which will act as dataprovider for tree.
and this canvas is added as a child for a panel in my main
application.
Hope this gives an idea.

How to map a custom enum list to a custom form property in an extended incident class

Hi,
I'm struggeling to understand how to map a custom enum list to a custom form property in an extended incident class.
Here's what i want to have happen:
I am going to publish a request offering on my SMPortal for allowing users to submit basic IT incidents. I want the form to include "Whom does this problem affect" (answers(This is the custom enum list): Me, Multiple Users, Whole department or Whole
company), "What is the problem about", "Description" and "Attachments".
Here's what i've done:
In the authoring tool i created a MP for the custom enum list and put only the list in it. I sealed the MP and imported it.
I created another unsealed MP called TST.Incident.Library for storing incident library customizations and extended the incident class to add an extension class i called ClassExtension_Affected scope with a custom property i called AffectedScope. Then i am trying
to set the datatype of this property to "list". In the "select a list" dialog i cannot chose my previously sealed MP with the custom enum list in it. Why?
- Do i need to scratch the sealed MP and put the custom enum list in the latter TST.Incident.Library MP instead?
- If so, can i do that and keep this MP unsealed, or will i get an error on import saying "Unsealed management packs should not contain type definitions"
- Should i create one sealed MP for both the custom enum list and the extension class + custom property?

Hi,
Authoring Tool simply isn't informed about your list. Open the sealed management pack where you define the root of the list in the Authoring Tool and in the same time open TST.Incident.Library. You will have two opened MPs in the Authoring
Tool and be able to add a custom list for your custom field.
Cheers,
Marat

Abstract class extends other class?

What happens when a abstract class extends other class?
How can we use the abstract class late in other class?
Why do we need an abstract class that extends other class?
for example:-
public abstract class ABC extends EFG {
public class EFG{
private String name="";
private int rollno="";
private void setName(int name)
this.name=name;
private String getName()
return this.name;
}

shafiur wrote:

How can we use the abstract class late in other class?Define "Late". What "other class"?
Why do we need an abstract class that extends other class?Because it can be useful to define one.

How to extend a class in same package

I have a class called LoginBean.java which extends the class ConnectDB.java

How to Extend Java class in UI Module

Hi All,
I am trying to make z for one of the java file GenericSearchDynamicContent.java in the standard package com.sap.wec.app.common.module.catalog.ui.utils. Can anyone please let me know what are steps do i need to follow to extend the same java file in our customer namespace and make use of it.
Thanks in Advance.
Regards,
Rahul.

Hi Rahul,
It's upto you whether you want to keep seprate packages for custom changes (then create your own package and keep all the Z class under this) or create a Z_GenericSearchDynamicContent.java and extend this class by GenericSearchDynamicContent.java.
After doing this you can make your custom changes accordingly and you have to also make the changes in *config.xml (replace this entry GenericSearchDynamicContent by Z_GenericSearchDynamicContent.java.) files as mapping is done there.
Could you please let me know if you need any further information.
Thanks,
Hamendra
