Accessing Objects from a Class

Hello,
I have a process that calls a method from a class, at runtime, the object creates a reference and in the reference I need to access an object, basically this is what I have at run time:
Object: WA_OBJECT
Reference:
If I double click on my object I get the following sub objects:
CL_PT_REQ_HEADER
   IF_PT_REQ_HEADER~CURRENT_VERSION
   IF_PT_REQ_HEADER~MAX_VERSION_NO
   IF_PT_REQ_HEADER~MY_REQUEST
   ITEM_TAB
if I double click on any of those items, it is fine in debugging, I can see the values, but in my program, I need to access the ITEM_TAB internal table, now I cannot use WA_OBJECT-ITEM_TAB. If I double click on the ITEM_TAB, now the main object becomes -ITEM_TAB[1], so cannot reference to that object in my program, so the question is how do I access the table?
Thanks for any answers.

Hello Enrique
ITEM_TAB is a <i>public </i>instance attribute of class CL_PT_REQ_HEADER. Thus, you can directly access them using
DATA:
ls_item    TYPE PTREQ_ITEMS_STRUC,
lo_item    TYPE IF_PT_REQ_ITEM.
LOOP AT wa_object->item_tab INTO ls_item.
    lo_item = ls_item-item.
ENDLOOP.

Accessing the same object from multiple classes.

For the life of me I can't workout how I can access things from classes that haven't created them.
I don't want to have to use "new" multiple times in seperate classes as that would erase manipulated values.
I want to be able to access and manipulate an array of objects from multiple classes without resetting the array object values. How do I create a new object then be able to use it from all classes rather than re-creating it?
Also I need my GUI to recognize the changes my buttons are making to data and reload itself so they show up.
All help is good help!
regards,
Luke Grainger

As long as you have a headquarters it shouldn't be to painfull. You simply keep a refrence to your ShipDataBase and Arsenal and all your irrellevant stuff in Headquarters. So the start of your Headquarters class would look something like:
public class Headquarters{
public Arsenal arsenal;
public ShipDatabase db;
//constructor
public Headquarters(){
    arsenal = new Arsenal(this, ....);
    db = new ShipDatabase(...);
//The Arsenal class:
public class Arsenal{
public Headquarter hq;
public Arsenal(Headquarter hq, ....){
    this.hq = hq;
    .Then in your ShipDatabase you should, as good programing goes, keep the arraylist as a private class variable, and then make simple public methods to access it. Methods like getShipList(), addToShipList(Ship ship)....
So when you want to add a ship from arsenal you write:
hq.db.addToShipList(ship);
.Or you could of course use a more direct refrence:
ShipDatabase db = hq.db;
or even
ShipList = hq.db.getShipList();
but this requires that the shiplist in the DB is kept public....
Hope it was comprehensive enough, and that I answered what you where wondering.
Sjur
PS: Initialise the array is what you do right here:
//constructor
shipList = new Ship[6];
shipList[0] = new Ship("Sentry", 15, 10, "Scout");
" " " "etc
shipList[5] = new Ship("Sentry", 15, 10, "Scout");PPS: To make code snippets etc. more readable please read this article:

Accessing objects from an existing JVM on Windows

I have a Java class that is running in an existing JVM which is running on local windows workstation. Is there a way I can access any methods or objects from the running Java class and other objects running inside the JVM from C or C++ code using Invocation API?. I know there is a way for us to ATTACH to a JVM that was created from C/C++ but I am looking for a way to access objects from a JVM that was started either as a service or started by other means.

How did you start the C++ code?
It is possible to load the c++ dll within your Java code then you may access the c++ code by using native methods out of Java. By calling the c++ method you have the pointer to your Java object and my use it (=> don't forget to use global references).
If you have started both seperatly C++ in an extra process and Java in an extra process then it can be complicated. Guess that there aren't any easy solution.
This mean: either you have your Java code loading a dll or you have C++ creating a JVM...

Why can't I create new object from a class that is in my big class?

I mean:
class A
B x = new B;
class B
and how can I solve it if I still want to create an object from B class.
Thank you very much :)

Is there a way to access object from other schema?

1. Is there a way to access object from other schema
Without using synonym/public synonym without prefixing schema owner?
2. If you do not see any object in all_objects by same name owned by connected user or public, can there still be objects hidden from this view? for instance synonyms created by SYSTEM
TIA for help

Well, you missed something somewhere. If there is no
ALTER SESSION SET CURRENT_SCHEMA=whoeverthen there must be either public synonym for the object as this shows:
SQL> CREATE USER a identified by a;
User created.
SQL> GRANT CREATE SESSION to a;
Grant succeeded.
SQL> CREATE USER b identified by b;
User created.
SQL> GRANT CREATE SESSION, CREATE PROCEDURE, CREATE PUBLIC SYNONYM to b;
Grant succeeded.

SQL> connect b/b

SQL> CREATE PUBLIC SYNONYM test FOR TEST;
Synonym created.
SQL> connect a/a

SQL> desc test
PROCEDURE TESTITAnother possibility without public synonyms is that crv had granted the other user privileges on some object, and the other user creates a private synonym for that. When crv granted privileges on a different object with the same name, the private synonym became valid again. Something like:
SQL> connect /
Connected.
SQL> drop public synonym test;
Synonym dropped.
SQL> GRANT CREATE SYNONYM TO a;
Grant succeeded.
SQL> connect a/a
Connected.
SQL> desc test;
ERROR:

SQL> desc b.test

SQL> CREATE SYNONYM test FOR b.test;

SQL> desc test;
FUNCTION test RETURNS NUMBER
Argument Name                  Type                    In/Out Default?
P_NUM                          NUMBER                  INSo, I would go looking for the synonyms.

Creating an arrays of objects from a class

I was wondering does any one know how to create an array of objects from a class?
I am trying to create an array of objects of a class.
class name ---> Class objectArray[100] = new Class;
I cant seem to make a single class but i need to figure out how to create an array of objects.
I can make a normal class with Class object = new Class

There are four lines of code in your for-loop that actually do something:
for(index = 0; index < rooms.length; index++) {
/*1*/ assignWidth.setWidth(Double.parseDouble(in.readLine()));
/*2*/ rooms[index] = assignWidth;
/*3*/ assignLength.setWidth(Double.parseDouble(in.readLine());
/*4*/ rooms[index] = assignLength;
}1.) Sets the width of an object, that has been instantiated outside the loop.
2.) assigns that object to the current position in the array
3.) Sets the width of a second object that has been instantiated outside the loop
4.) assigns that other object to the current position in the array
btw.: I bet you meant "assignLength.setLength(Double.parseDouble(in.readLine());" in line 3 ;)
Since each position in an array can only hold one value, the first assignment (line 2) is overwritten by the second assignment (line 4)
When I said "construct a new room-object and assign it to rooms[index]" I meant something like this:
for(index = 0; index < rooms.length; index++) {
    Room aNewRoom = new Room();
    aNewRoom.setWidth(Double.parseDouble(in.readLine()));
    aNewRoom.setLength(Double.parseDouble(in.readLine());
    rooms[index] = aNewRoom;
}1.) Constructs a new Object in every iteration of the for-loop. (btw: I don't know what kind of objects you're using, so this needs most likely modification!!)
2.) set the width of the newly created object
3.) set the length of the newly created object
4.) assign the newly created object to the current position in the array
-T-
btw. this would do the same:
for(index = 0; index < rooms.length; index++) {
    rooms[index] = new Room();
    rooms[index].setWidth(Double.parseDouble(in.readLine()));
    rooms[index].setLength(Double.parseDouble(in.readLine());
}but be sure you understand it. Your teacher most likely wants you to explain it ;)

How to access form objects from different class?

Hello, I am new to java and i started with netbeans 6 beta,
when i create java form application from template i get 2 classes one ends with APP and one with VIEW,
i put for example jTextField1 with the form designer to the form and i can manipulate it's contents easily from within it's class (let's say it is MyAppView).
Question>
How can i access jTextField1 value from different class that i created in the same project?
please help. and sorry for such newbie question.
Thanks Mike

hmm now it says
non static variable jTree1 can not be referenced from static context
My code in ClasWithFormObjects is
public static void setTreeModel (DefaultMutableTreeNode treemodel){
jTree1.setModel(new DefaultTreeModel(treemodel));
and in Class2 it is
ClasWithFormObjects.setTreeModel(model);

Accessing variable from another class

Say I want to access String ABC from class XYZ from my main class. I have already created the object for the class I just don't know the syntax for accessing the variable.
This is just an example. I figured this is just a problem of finding the right syntax so I didn't bother creating a compiling code.
public class test{
public static void main(String[]args){
     XYZ xyz = new XYZ ();
     String a = abc.XYZ(); // this is where i want to directly access the variable abc. i know this isn't correct and it's what im trying to find out how to do.
public class XYZ{
     String abc = "hi";
}Edited by: aznprdgy on Nov 3, 2009 2:13 PM

No, that isn't possible.
abc is said to be a local variable. And it's only useable within method().
It's part of the job of the class Xyz to control the access to its state. As an example:
public class Test {
    public static void main(String[] args) {
        Xyz xyz = new Xyz()
        String a = xyz.getSpecialValue();
public class Xyz {
    private String a;
    public String getSpecialValue() {
        return a;
    public void method() {
        a = "hi";
}Note that a won't be reference to the string "hi" until after method() has been called.

How to pass arraylist of object from action class to jsp and display in jsp

I need to do the following using struts
I have input jsp, action class and action form associated to that. In the action class I will generate the sql based on the input from jsp page/action form, create a result set. The result set is stored as java objects in a ArrayList object.
Now I need to pass the arraylist object to another jsp to display. Can I put the ArrayList object in the request object and pass to the success page defined for the action? If this approach is not apprpriate, please let me know correct approach.
if this method is okay, how can I access the objects from arraylist in jsp and display their property in jsp. This java object is a java bean ( getter and setter methods on it).
( need jsp code)
Can I do like this:
<% ArrayList objList = (ArrayList)request.getattribute("lookupdata"): %> in jsp
(***I have done request.setattribute("lookupdata", arraylistobj); in action class. ***)
Assuming the java object has two properties, can I do the following
<% for (iint i=0. i<objList.size;I++){ %>
<td> what should i do here to get the first property of the object </td>
<td> what should i do here to get the first property of the object </td>
<% }
%>
if this approach is not proper, how can I pass the list of objects and parse in jsp?
I am not sure what will be the name of the object. I can find out how many are there but i am not sure I can find out the name
thanks a lot

Confusion... Data Access Object and Collection Class

Please help me...
i have a Book class in the library system, so normally i would have a Collection class eg. BookCollection class which keeps an array/ arrayList of Book objects. In BookCollection class i have methods like
"searchBook(BookID)" which would return me a Book object in the array.
But now i'm confused with Data Access Object... In sequence diagrams there's a "Data Access class" which is used to retrieve data from and send data to a database. So, if i have the Data Access class, do i still need BookCollection class? Because BookCollection serves as a database also rite? ...

I think you're in the right rail.
The BookCollection class could be still usefull if you will need to manage search results with more than onne record (e.g.: search by author name).

How do i use objects from one class in anohter?

Hey
I have two GUI classes ShowWhiteGUI and BasketGUI and then a control class ShowWhite. The control class calls all the method from anohter class's which the GUI classes are gonna use.
The basis idea with this script is it shall be a very very simpel Shop. Where you can add items to a basket and then show the items in a new window(BasketGUI).
So here is the problem. I cant create an object in both GUI classes, because then im working with two sets of data, right? So how do i do this?

How do I access data from another class?

I have a class RailNetwork which extends Datastore. DataStore contains a vector filelines which I need to access from RailNetwork. How do I do this? What do I put infront of filelines.get(i); ?
public abstract class DataStore
{    Vector<String> fileLines = new Vector<String>(); }
public class RailNetwork extends DataStore
{    ...main(){ .......filelines.get(i);....... }
}

This is the code from RailNetwork class:
public static void main(String[] args) {
          String templine;
          int i = 0;
          int vectorlength = super.filelines.size();
          for( i = 0 ; i < vectorlength ; i++ )
               templine = (String) super.filelines.get(i);
               setStations(templine); }The errors (for both lines, only 1 shown):
RailNetwork.java:49: non-static variable super cannot be referenced from a static context
                        templine = (String) super.filelines.get(i);
                                            ^
RailNetwork.java:49: cannot find symbol
symbol : variable filelines

                        templine = (String) super.filelines.get(i);

How to access the objects from multiple classes in ABAP Objects

<b> Give me The scenario and solution to the above problem </b>

In abap OO you can have only one super class.
multiple inheritence can be acheived by inheriting multiple interfaces.
abap OO is similler to that of JAVA in inheritence.
so you can not have classes a and b both as super at same time for a class.
however if still you want to acheive your perpose then you can do it using heirarchical inheritance where b inherits a and c inhrites b. so this way public methods will be accesible in c
do revert back if any other doubt.
check this link for more clear picture:
