Class Creation

I'm trying to create a class that represents all 52 playing card (Suit and Value), and I'm having difficulties. I'll then create a function in my Document class that compares two card objects as parameters and traces out which one would win in a fight (aka War).

Its more along the lines of how do I get started. This is part of my homework for my Intro to Programming class. What I have so far is
package cardCode
     import flash.display.MovieClip;
     public class Card extends MovieClip
          public var cardValue:Number;
          public var cardSuit:String;
          public function card() {
          // constructor code
I don't know how to go about assigning values and suits. The final outcome wil be so that you can compare two cards and a trace statement will appear stating which card wins.

ABAP class creation

I would like to know what is ABAP class creation (Table API). Also would like to know how is it related to SAP BW reports.

Are you talking about creating a ABAP class via SE24?

Message class creation

Can any body tell me how to creat message class and also the message numbers in the class.
like in message class F2 the message number is 273 for giving error message if find the same VAT registration number during creation of customer master.
Rgds.
Laxmikanta Das.

Hi Das
F2 is standard message class. Dont change the standard. (SE91) Copy the F2 into Z.... Save the new message class. Inside the message class,Message number 000 to 999 is display. Here add your own messages.

Dynamic class creation

hi,
I need to create new classes (not objects) dynamically in my program and then objects of that type.
For example if the user asks to create a class with int, float & char as its data fields, and such class is not yet defined, I need to create such class and then instantiate it.
I m creating class.java using and then compiling it using Runtime.getRuntime.exec() to get corresponding class file.
But I m facing problem in instantiating it.
code goes like this:
import java.util.*;
import java.io.*;
public class Main {
            public Main() {
    public static void main(String[] args) {
        String key="fi";
        Hashtable hs= new Hashtable();
        if(hs.contains(key))
        else
           // hs.put(key,)
           try{
               PrintWriter pw = new PrintWriter(new FileOutputStream(key+".java"),true);
              pw.println("public class "+key+"{");
               for(int i=0; i< key.length(); i++)
                   char c = key.charAt(i);
                   switch( c )
                       case 'i' : pw.println("int i;");
                        break;
                       case 'f' : pw.println ("float f;");
                       break;
               pw.println("public " + key + " next=null; ");
               pw.println("public static int count=0;");
               pw.println("public "+ key +" first=null;");
               pw.println("public "+ key +" last=null;");
               pw.println("public static int delta=0;");
               pw.println("}");
            Runtime.getRuntime().exec("javac " +key+ ".java");
           catch(Exception e){e.printStackTrace();}
//           key1 in =new key1();
           //fi in = new fi;
}    Now after try catch block I m trying instantiate the class whose name is in key. (here key value is fi and I need create instnce of fi)

No, The classloader associated with a class is the one that loaded it, which in the case of System.class will be the primordial class loader which "loads" classes which are actually built into the JVM. It probably won't even see the ClassPath, You'd be better putting the class files you generate on the fly into a special folder reserved for that purpose and create a URLClassLoader to load them.
However, as has been pointed out, the question is; how are you going to use them? In general, dynamically loaded classes are only useful if they are known to implement an interface, or extend a class, available at compile time. It's pointless to create a class as a container object, for example, because if you can only access the fields through reflection it's slower, and more complicated, than using something like a HashMap.

IPM & CIS and Document Class creation

If I've to setup a new Content Management System with process management, what are the advantages I get if I integrate UCM with IPM?
1. Can't IPM provide the versioning and document management features?
2. How can I create various document classes (as in Documentum, FileNet)? The idea is to create various document classes and associate folders and workflows with those classes. Thus once created, documents automatically go into workflow. Note that workflows can be associated with folders. I want them to be associated with document types.

Class Creation Problem in Publish settings

now iam working in flash 8 version .fla file.......firstly iam save as it to cs4 via Macromedia flash cs4....when i trying to add a new main class for this file
it showing error as
"This feature is not supported by flash 8 , Action script 2.0,to use this feature ,you must flash player 9,Action script 3.0"
but when i publish this to flash player 9,Action script 3.0 it not working properly..........is there any suggestion to avoid this problem???????

if you want to use a document class, you must publish for as3. if you're using as2 code, you'll need to change all the code to as3.
the simplest solution is to leave it an as2 file and not use a document class.
or, you could create a main as3 swf that has a document class and load your as2 swf into your main as3 swf.

Class creation at Runtime?

Hi,
How can I create a class at Runtime? I want to create multiple classes having structure (say):
public class MyClass{
public void myMethod(){
System.out.println("Some Text")
}Now I want to create multiple classes at runtime having name "MyClass1.class", "MyClass2.class", ......
Please Help.
Thanks,
Sumit

Actually, I want those multiple classes
("Myclass1.class", "Myclass2.class".....) to be
present physically on the machine. As some other
program then going to load those classes later on.
Any Solution?How about defining a single class, whose instances can be described with a standard set of data. Say, that data could be represented by java.util.Properties object, and this class will have a constructor that takes a Properties as an argument.
Then this other program will load files in the format used by Properties, then it will use Properties.load() to load the data from these files, and then instantiate the class. Rather than loading lots of different classes.
Or not. It's up to you.

Very basic noob question about understanding class creation

After learing some procedural scripting I just started with understanding OOP and have a problem with a basic stuff like this. Why my Try.as below is not working when I type Try(1); in the main file. Output says: Type Coercion failed: cannot convert 1 to Try
package {
    public class Try {
        public function Try(some:Number) {
            some += 1;
             trace (some);

use:
var s:Try = new Try(3);

Common class creation

Hello Anybody,
In my application, I have nearly ten different forms, where i have to take picture from album/camera using UIImagePickerController. So instead of using the UIImagePickerController in ten view controllers, I wish to use it as a common class.
So how can I make this possible? Please advice me with example.
Nalan.

Why not have a base controller class that implements all the common features, and then sub-class that for your individual controllers?

Development Class creation and migration?

How do we create the development class?Please explain and also is it normal procedure to migrate the development class or it is differnet?
Poitns will be definitley assigned.
Before transporting any object which are avialable in that Development class Do I need to first transport the Development class and then I need to tranpsport the other objects right?
Edited by: Ravi Kumar on Dec 2, 2009 1:54 PM

Try this:
1) Go to tcode SE80
2) Click on Other Object button
3) Go to the More... tab and ensure the Development Class radio button is selected
4) Type in the Name of the Development Class (must begin with Z or Y)
5) Click on the Create button
6) Enter a Description for the Development Class
7) Click on Save
8) A Workbench Request (transport) popup should appear for you to assign the Development class to a transportable package and add to a transport
This Development Class needs to be transported throughout the landscape prior to any objects being transported through the landscape (e.g. the Development Class must be in QA prior to objects developed on that Development Class being moved to QA).

Proxy class creation using wsdl

Hi Everyone
There is a web service already running and what i have is the wsdl of that web service. How do i create the proxy classes for this webservice using the JWSDP
Please help its urgent. Or atleasst direct me to any links for this query. Any help is welcome
Thanks in advance
Maria

Edit a file named config.xml :
<?xml version="1.0" encoding="UTF-8"?>
<configuration
xmlns="http://java.sun.com/xml/ns/jax-rpc/ri/config">
<wsdl location="http://{path}/{serviceName}?WSDL"
packageName="client">
</wsdl>
</configuration>
and try this command : xrpcc -client config.xml
It will generate all the client-side classes.
Finally, write a client that accesses to these classes.
package client;
import javax.xml.rpc.Stub;
public class Client {
public static void main(String[] args) {
try {
          Stub stub = createProxy();
          stub._setProperty(javax.xml.rpc.Stub.ENDPOINT_ADDRESS_PROPERTY,args[0]);
          CITClientIF_Stub cl = (CITClientIF_Stub)stub;
          result=cl.Method(...);
} catch (Exception ex) {
ex.printStackTrace();
private static Stub createProxy() {
return (Stub)(new MyCIT_Impl().getCITClientIFPort());

ApplicationModule Class creation and then delete?

Hi all,
sorry if the question sound weird,
what if I created the AppModuleImpl.java
then figured that no need for any modification on it,
what would be the implication of deleting the created implementation file , (right Click -> delete -> and delete all the usages of the java files in the AppModule.xml)
same is for the view Implementation classes.
as far as I know, that at run time the super implementation classes executed based on the specific properties for each e.g: view from the xml files.
regards
Edited by: Knowledgestudent on Nov 25, 2010 4:25 AM

If I get your question right, there should be no problem deleting the applicationModuleImpl java file. You normally don't delete it this way. To remove the impl file you open the application module, select the 'Java' node, click the pencil and remove the check mark from 'Generate Application...'.
