How to subtract List ?
how to subtract List ?
subtract rule
List1=["a","b","c"]
List2=["a","b","c","d"];
List2-List1="d".
i dont find any subtract method in ArrayList . how do i do it ?
Because it isn't called subtract it's called removeAll(Collection c);
list2.removeAll(list1);Leaves list2 with "d"

How to add records or how to maintain list in stored Procedure
Hi,
I am facing an issue in the addition of record in the type
create or replace
TYPE "PROD_SEARCH_COUNT_TBL" AS TABLE OF PROD_SEARCH_COUNT_OBJ;
create or replace
TYPE "PROD_SEARCH_COUNT_OBJ" AS OBJECT
( /* TODO enter attribute and method declarations here */
V_Name Varchar2(500 Byte),
v_Value Varchar2(500 Byte),
v_count Number
I want to add records to the type I tried following way
prod_wcf_rec PROD_SEARCH_COUNT_TBL;
SELECT PROD_SEARCH_COUNT_OBJ('Name1','Value1',1) BULK COLLECT INTO prod_wcf_rec FROM DUAL;
SELECT PROD_SEARCH_COUNT_OBJ('Name2','Value2',2) BULK COLLECT INTO prod_wcf_rec FROM DUAL;
SELECT PROD_SEARCH_COUNT_OBJ('Name3','Value3',3) BULK COLLECT INTO prod_wcf_rec FROM DUAL;
SELECT PROD_SEARCH_COUNT_OBJ('Name4','Value4',4) BULK COLLECT INTO PROD_WCF_REC FROM DUAL;
DBMS_OUTPUT.PUT_LINE ('-----------------------------Looping----------------------------');
FOR i in 1 .. prod_wcf_rec.COUNT
LOOP
DBMS_OUTPUT.PUT_LINE (prod_wcf_rec(i).V_Name||' - '||prod_wcf_rec(i).v_Value||' - '||prod_wcf_rec(i).v_count);
END LOOP;
DBMS_OUTPUT.PUT_LINE ('-----------------------------Looping----------------------------');
In printing I am getting last records only .So is there any way to add records to PROD_SEARCH_COUNT_TBL
How to add records or how to maintain list in stored ProcedureEvery time you BULK COLLECT into a collection type the value is overwirtten. So you need to try something like this.
SQL> create or replace type prod_search_count_obj as object(v_name varchar2(500 byte), v_value varchar2(500 byte), v_count number)
2 /
Type created.
SQL> create or replace type prod_search_count_tbl as table of prod_search_count_obj
2 /
Type created.
SQL> declare
2 prod_wcf_rec prod_search_count_tbl;
3 begin
4 select obj_val
5 bulk collect into prod_wcf_rec
6 from (
7 select prod_search_count_obj('name1','value1',1) obj_val from dual
8 union all
9 select prod_search_count_obj('name2','value2',2) from dual
10 union all
11 select prod_search_count_obj('name3','value3',3) from dual
12 union all
13 select prod_search_count_obj('name4','value4',4) from dual
14 );
15
16 dbms_output.put_line ('-----------------------------looping----------------------------');
17 for i in 1 .. prod_wcf_rec.count
18 loop
19 dbms_output.put_line (prod_wcf_rec(i).v_name||' - '||prod_wcf_rec(i).v_value||' - '||prod_wcf_rec(i).v_count);
20 end loop;
21 dbms_output.put_line ('-----------------------------looping----------------------------');
22 end;
23 /

name1 - value1 - 1
name2 - value2 - 2
name3 - value3 - 3

How can I list the songs in an album in iTunes without having to do it one by one? Some albums are not numbered or they show 1. 1. 1. 1. 1. 1. 1.
Poor metadata needs to be corrected if the album is to display properly in iTunes. iTunes sees an "album" as any collection of tracks with the same Album title and the same Album Artist (or Artist if Album Artist isn't set). Each track of the album should have distinct Track V of W and Disc X of Y vaules. W,X,Y are optional, but X may be needed for multi disc albums.
See Gropuing tracks into albums for details.

How to print/list all the groups/users present in Weblogic using Java code
Hi,
Weblogic version : 11.1.1.5
How to print/list all the groups/users present in Weblogic using Java code
I want to make a remote connection to Weblogic server and print all the users/groups present in it.
I have gone through the below mentioned site, but I cannot use the same approach since most of the API' are deprecated for example "weblogic.management.MBeanHome;"

How can I list all the domains configured for Weblogic Servers?
How can I list all the domains configured for Weblogic Servers?
I saw a note, which says the following:
"WebLogic Server does not support multi-domain interaction using either the Administration Console, the weblogic.Admin utility, or WebLogic Ant tasks. This restriction does not, however, explicitly preclude a user written Java application from accessing multiple domains simultaneously."
In my case, I just want to list all the domains, is that possible by using any scripts?
Thanks
AJIf you use WLS Node Manager and the Config Wizard was used to create the domains, then the list of domains should be in a location like this:
<MIDDLEWARE_HOME>\wlserver_10.3\common\nodemanager\nodemanager.domains
Enterprise Manager Grid Control also has support for multi-domain management of WLS in a console. -

How to create list of a View's column names and source
Using SQL 2005, 2008, and 2012
How to create list of a View's column names and source. For the following example would like to @Print something like the following. Does anyone already have some code to do this? I realize there are probably some gotchas, but the views that I am looking
at to use this follows the code snippet pattern below.
DBACCT.[Account Number]
dbo.ConvertDate(DBACDT). [Boarding Date]

Please tell me how to handle list item in this concern
please tell me how to handle list item in this concern
My problem is:
i have a category table with column categoryname(varchar type)
I want to display the records of categoryname in a drop down list (i.e., list item )
So ..please tell me how to do it
Thanks in advance..This code is just a sample from the Help documentation. It won't work until you modify it for your form.
Why do you have "steps" in your code? You are suppose to do what the steps tell you. You don't place the steps in your code. The steps must be removed from your code.
Step 1 code goes in a program unit, not in a trigger.
Step 2 and 3 code usually goes in a trigger.
You will have to replace the names of the items and record group with your own names as you have defined them in your form.
step 1: create a procedure in your application
procedure load_list(itm in VARCHAR2, rg in VARCHAR2) is
group_id RecordGroup := Find_Group(rg);
list_id Item := Find_Item(itm);
Begin
if Populate_Group(group_id)<>0 then
Message('Unable to populate record group');
Raise Form_Trigger_Failure;
end if;
Clear_List(list_id);
Populate_list(list_id, group_id);
end;
step 2: create a record group named rg_cat and assign Record Group Query to something like "select categoryname from category"
step 3: call this procedure as
load_list('categoryname','rg_cat'); -
How to populate list component via xml file?
There is a TextArea component that should show the name and
the description of the item selected in the list component. But I
dont know how to populate list with external XML and what should be
the coding in flash as well as what should be written in the XML.
Please help.Here's an xml file listing a couple of brother comedy teams:
<?xml version="1.0" encoding="UTF-8"?>
<team>
<brothers>
<Marx>
<name>Groucho</name>
<name>Chico</name>
<name>Harpo</name>
<name>Zeppo</name>
<name>Gummo</name>
</Marx>
<Howard>
<name>Moe</name>
<name>Curly</name>
<name>Shemp</name>
</Howard>
</brothers>
</team>
Open a new .fla and save it in the same folder as the .xml
file. Place a List Component on the Stage and name it (in this
case, "comicTeams_list"). In the first frame write the following
ActionScript:
//create XML object and load external xml file
var broList:XML = new XML();
broList.ignoreWhite = true;
broList.onLoad = processList; // this is a function that will
be written below
broList.load("populateList.xml");
function processList(success:Boolean):Void{
if(success){
loadList();
}else{
trace("Load failure");
function loadList():Void{
var broName:String;
var listEntries =
broList.firstChild.childNodes[0].childNodes[0].childNodes.length;
for(var i:Number = 0;i<listEntries;i++){
broName =
broList.firstChild.childNodes[0].childNodes[0].childNodes
.childNodes[0].nodeValue;
trace(broName);
comicTeams_list.addItem(broName);
//to make something happen when you click on a name in the
List, create a Listener and function
var broListListener:Object = new Object();
broListListener.change = someAction; //"someAction" is a
function to be written shortly
//add the Listener to the List
comicTeams_list.addEventListener("change", broListListener);
function someAction(evtObj:Object):Void{
var pickedBrother:String = evtObj.target.selectedItem.label;
//write actions here, referencing pickedBrother variable
The names of the Marx Brothers will appear in the box.
This is written in AS2. When you post a question, it's a good
idea include which version of ActionScript you're using. -
