Unchecked call to to add(E) ....... HELP

Hi, i was doing a project in eclipse, and everything was fine (compiled and running). However, I ran into this problem when I try to compile the same code in DOS command line. Is there any ways that I can fix this problem so the same code that runs in Eclipse can compile in DOS also?
a glimpse of the code is below:
ArrayList best_move = new ArrayList();
for ( ..r... )
   for( ..c.... )
       Move move = new Move( r, c);
       if( move is valid )
            then
                best_move.add(move);warning: [unchecked] unchecked call to add(E) as a
member of
the raw type java.util.ArrayList
best_move.add((Move) move);Appreciate your help.

try the following
ArrayList<class name> best_move = new ArrayList<class name>();
for ( ..r... )
   for( ..c.... )
       Move move = new Move( r, c);
       if( move is valid )
            then
                best_move.add((class name)move);in above "class name" is the class of the object which u wanna store in the collection e.g java.lang.Integer or java.lang.Float etc.
this will not give any warnings in jdk1.5 and will help u out.

Unchecked call to add element

I get the following warning:
warning: [unchecked] unchecked call to addElement(E) as a member of the raw type java.util.Vector
from the line:
((Vector)results.get( "ALL" )).addElement( new Result( date, home, hg, ag, away ) ) ;I have had no problems fixing this warning with simple lines like:
private Hashtable<String,Object> results = new Hashtable<String,Object>() ;but as you can see it is a bit more tricky.
The compiler highlights:
( new Result( date, home, hg, ag, away ) ) ;as the warning. The Result Object takes parameters <String,String,Integer,Integer,String> if that helps.
Can anyone suggest how to fix this warning please?

Are all values in your hastable vectors of results, or will that only be true when the key is "ALL". If they all contain Vectors you can rewrite the code as follows
private Hashtable<String, Vector<Result>> results = new Hashtable<String, Vector<Result>>();
results.put("ALL", new Vector<Result>());
results.get("ALL").addElement(new Result (date, home, hg, ag, away));Or if you want to keep your code more flexible change Vector to it's interface List. That will reduce the amount of work you have to do if you decide you don't want to use Vectors any more and use ArrayLists.
private Hashtable<String, List<Result>> results = new Hashtable<String, List<Result>>();
results.put("ALL", new Vector<Result>());
results.get("ALL").add(new Result (date, home, hg, ag, away));Of course none of this will work if your map contains values other than Vectors of results.

JDK 6: Generics: List.add() question - keep getting unchecked call warning.

JDK 6
Generics
private TreeNode transactionTreeData;
transactionTreeData.getChildren().add(moduleData);1. transactionTreeData is a TreeNode.
2. the method getChildren() returns a java.util.List
3. the method add() is from the Collection interface.
I keep returning the warning message:
"unchecked call to add(E) as a member of the raw type java.util.List"
I understand what this means, but I am having problems rewriting these lines correctly to remove the warning.
I've tried:
private TreeNode transactionTreeData;
List<TreeNode> treeList = transactionTreeData.getChildren();
treeList.add(moduleData);But I keep returning the same warning message. I guess what is throwing me off is how to I properly add the generic statements when the List is return from a method (getChilden in this example)?
Thanks,
--Todd

This is actually JSF - MyFaces Tomahawk to be exact, my mistake for not adding that in my original thread.
I am dealing with the compiled class:
package org.apache.myfaces.custom.tree2;
public interface TreeNode extends java.io.Serializable {
     java.util.List getChildren();
}TreeNode.getChildren return a raw List as you can see, no doubt...
Thanks,

Unchecked Call to addElement(E)

I'm trying to store AudioClip objects in a vector. It compiles with a warning:
AudioHolder.java:19: warning: [unchecked] unchecked call to addElement(E) as a member of the raw type java.util.Vector
soundVector.addElement(temp);
Temp is an AudioClip, but even when I make it something simple like an int or a String, it still throws up the same warning. At runtime, the line of code comes up with a nullpointer error. Can someone help me figure out how to fix this?

The unchecked warning is just that: a warning, which you can safely ignore. All it's saying is that you could have taken advantage of the greater type-safety provided by jdk1.5 generics, for example: Vector<AudioClip> soundVector = new Vector<AudioClip>();
AudioClip temp = getAudioClip(); // or whatever
soundVector.addElement(temp); // no warningThe NullPointerException is not related to the unchecked warning. You probably tried to call a method or access a field on a null reference.

Removing unchecked call warnings

I have moved from 1.4.2 to 1.5.0 today, and now I'm trying to solve all the unchecked call warnings that I had in the code, but I have one that I don't know how to avoid it.
I need a matrix of nxn dimensions where every element is an Integer. I was creating this matrix in a recursive way, with a recursion deep of n. For example, if n=3, I had finally a Vector<Vector<Vector<Vector<Integer> > > >. As n is configurable by the user, I can't determine the data types that i must declare in the recursive calls that I use to manage the matrix.
There is a class to implement my "matrix" in a simplest way?
If not, there is a way to remove the warnings in the recursive calls?
If not, I suppose that I must keep the warnings...
Jorge

Well, my use of the matrix is not mathematical but to represent the "real world".
I'm working in the project previous to the University graduation, and I'm implementing a communication protocol among different computers.
Those computers are linked in n dimensions (I have let configurable the dimensions because I think that flexibility is important for things like this).
If n=1, the computers are linked like this:
A - B - C -D - E -F - G - H - J
If I have n = 2 the computers are linked like this:
A - B - C
| \ | / |
D - E - F
| / | \ |
G - H - J
(Well, in the post preview this last configuration looks very bad because some spaces are trim: The "E" computer is linked to all the rest of computers)
If I have n = 3 the computers are linked in a cube shape, if I have n = 4 in an hipercube, and so on.
That's why I need a multidimensional matrix to represent my network.
I have a class that encapsulates the access to all the linked neighbours of a computer, and internally it stores these neighbours as a Vector of Vector's. of Vector's...(n times)
For example, to create all the neighbour objects, I must write code like this:
private Vector neighbours; // I don't know what I must write inside <> next to Vector declaration
neighbours = new Vector(LINKS_IN_DIMENSION); // Again, the warning complains the lack of <>, but I don't know what goes inside
initializeDimensionVector(1, neighbours);
// In the method declaration, I need again the <> specification but is not possible
private void initializeDimensionVector(int dimension, Vector vecDimension)
     vecDimension.setSize(LINKS_IN_DIMENSION);
     if ( NET_DIMENSIONS == dimension )
          for ( int i = 0; i < LINKS_IN_DIMENSION; ++i )
          vecDimension.setElementAt(new NeighbourDirectlyConnected(), i);
          return;
     for ( int i = 0; i < LINKS_IN_DIMENSION; ++i )
          // And finally here, for the new recursive call, the unspecified Vector declaration appears again
          vecDimension.setElementAt(new Vector(LINKS_IN_DIMENSION), i);
          initializeDimensionVector(dimension + 1, (Vector)vecDimension.elementAt(i));
}The number of dimensions n is represented by NET_DIMENSIONS.
The other constant (LINKS_IN_DIMENSION) tells how many different indexes we have per dimension.
Hope this sample code explains a little bit what I'm trying to do.
I can close my eyes and forget the warnings, but I come from the C++ world and experience tells that warnings musn't be ignored.
Regards and thanks for your help.

HOW to ADD F4 help to a field on SCREEN (MODULE POOL)

Hi,
     How to add f4 help to a field in screen ..plz help
Regards,
Saleha

Hi Saleha,
                In order to add F4 help to a field in modeule pool follow these steps:-
1. First go to SE11 and create your own search help( if you dont know how to create a search help please feel free to ask me, it is very easy).
2. Now in your module pool program program go to the layout of your screen.
3. Now when you see the attributes of this field in the Dict tab you will find the field Search Help. Now here you can specify the name of the search help you created in SE11.
There is also another mehtod to create the dynamic search help. eg:- in a posted document data get the Document nos related to that company code.
The sample code is like this:-
First of all declare the module below in the flow logic of your screen then create it in your main program.
You declare the module in the PROCESS ON VALUE-REQUEST.
PROCESS ON VALUE-REQUEST.
FIELD TXT_DOCNO MODULE VALUE_BELNR.
You also need to create an internal table where you wil store results of the select query fired below in the module.
here you will get a F4 help on the filed Document Number(TXT_DOCNO) based on the field Company code (TXT_CODCO)
MODULE VALUE_BELNR INPUT.
progname = sy-repid.
dynnum   = sy-dynnr.
CLEAR: field_value, dynpro_values.
field_value-fieldname = 'TXT_CODCO'.
APPEND field_value TO dynpro_values.
CALL FUNCTION 'F4IF_FIELD_VALUE_REQUEST'
    EXPORTING
      tabname     = 'BKPF'
      fieldname   = 'BUKRS'
      dynpprog    = progname
      dynpnr      = dynnum
      dynprofield = 'TXT_CODCO'.
CALL FUNCTION 'DYNP_VALUES_READ'
       EXPORTING
            dyname             = progname
            dynumb             = dynnum
            translate_to_upper = 'X'
       TABLES
            dynpfields         = dynpro_values.
READ TABLE dynpro_values INDEX 1 INTO field_value.
SELECT BUKRS BELNR
    FROM BKPF
    INTO CORRESPONDING FIELDS OF TABLE it_doc1
    WHERE BUKRS = field_value-fieldvalue.
CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
       EXPORTING
            retfield    = 'BELNR'
            dynpprog    = progname
            dynpnr      = dynnum
            dynprofield = 'TXT_BELNR'
            value_org   = 'S'
       TABLES
            value_tab   = it_doc1.
ENDMODULE.                 " VALUE_BELNR INPUT
Hope you find this information useful, let me know.

Add a Help Link to a Discoverer Portlet

How can I add a Help Link in a Discoverer Portlet?
Even if I have checked the 'Show Help Link on Portlet Headers' in the Portlet Display Options this does not appear in the Portlet.

Hi.,
As far I know it is not possible to create URL link in Area Menu., instead, Create a Report and call Function 'CALL_BROWSER' and pass the url to the function module.
Now create a Transaction for this report let say ZURL,
Now Assign this transaction to Area Menu So., When you click that transaction in Area menu it will open Url in browser.
hope this helps u.,

Warning about unchecked call

What does it mean?
warning: [unchecked] unchecked call to add(E) as a member of the raw type java.util.Vector properties.add(prop);
and how can I avoid this warning? what shall i check?

If you use -Xlint, it will tell you the line number.
Basically, though, you are compiling in j2se 1.5.0, but not specifying the type for the Vector. That is, you are using it in it's pre 1.5.0, raw mode, and it cannot do any compile time type checking for you.
Say you were using your vector to store Integers. You would declare it as Vector<Integer> myIntegerVector = new Vector<Integer>();and the warning would go away. Now the compiler can do compile time type checking, and let you know when you are using that vector with a type other than Integer, which might not be safe.
