How to Implement a Chained Hash Table with Linked Lists

I'm making a migration from C/C++ to Java, and my task is to implement a Chained Hash Table with a Linked List. My problem is to put the strings(in this case names) hashed by the table using de Division Metod (H(k)= k mod N) in to a Linked list that is handling the colisions. My table has an interface implemented(public boolean insert(), public boolean findItem(), public void remove()). Any Help is needed. Thanks for everyone in advance.

OK. you have your hash table. What you want it to do is keep key/value pairs in linked lists, so that when there is a collision, you add the key/value pair to the linked list rather than searching for free space on the table.
This means that whenever you add an item, you hash it out, check to see if there is already a linked list and if not, create one and put it in that slot. Then in either case you add the key/value pair to the linked list if the key is not already on the linked list. If it is there you have to decide whether your requirements are to give an error or allow duplicate keys or just keep or modify one or the other (old/new).
When you are searching for a key, you hash it out once again and check to see if there is a linked list at that slot. If there is one, look for the key and if it's there, return it and if not, or if there was no linked list at that slot, return an error.
You aren't clear on whether you can simply use the provided linked-list implementations in the Java Collections or whether you have to cobble the linked list yourself. In any case, it's up to you.
Is this what you're asking?

How to implement the RemoveLast function in a link list? check my code plz

Hi guys,
How to delete the last element in a user defined linklist. I am using the following code to find the last element of the list. It works fine, but i don't know how to remove that element ...
public Object getRear()
               rear=front;
               while (rear !=null)
                    if (rear.getNext()!=null)
                         rear=rear.getNext();
                    else
                         break; //rear Node found
               if (rear !=null) //list is not empty
                    return rear.getData();
                    return null; //list is empty
     }

Sorry, I missed out on returning the last element:
public Object delRear() {
// I assume front is an instance field pointing to the first element
if(front != null) { // list contains something
    Element rear, pred; // I assume you have some type like this
    // determine predecessor of last element
    rear = front;
    pred = null;
    while(rear.getNext() != null) {
      pred = rear;
      rear = rear.getNext();
    if(pred == null) front = null; // delete only element
    else pred.setNext(null); // delete last element
    return rear; // return deleted element
else return null;

Implementing a threaded Hash Table

Hiya all,
Would like to know how to create a threaded hash table. I am making a program that should be able to take in different variables such as string and integers, and be able to store then in a Hash table. Would it be possible to retreive these variables (remove them from the hash map) in a threaded scenario?

Unlike the new collection implementations, Hashtable
is synchronized.True, but HashMap is more stable. Its performance stays roughtly the same when it's loaded with different (biased) data sets whereas Hashtable shows much more variation.

Hi,
Try

Problem with Linked List

i have make a database with linked list for a School student counselor.
The to be store is
student name, ID, Counseling Date, Progress
In there there will be record for a student and the Date and progress has to be stored for 4-weeks as the counseling is on weekly basis. These data items will be multivalued(what u say in Databases) how i can store this repetitive data in linked list for one student.

By capsulating the data in objects and adding the objects to a linked list.

Getting null returned when working with Linked Lists

Ok, i'm having the same problem with a couple of methods that deal with linked lists, and i was hoping someone could lend me a hand. First off, the specifications for one of the methods:
An iterative procedure smallElements
PARAMETERS: a ListItem reference, ls
an integer n
RETURN VALUE: a new list identical to the given list, except
that it contains no occurrences of numbers greater than n.
for example, given input list ( 3 2 6 3 4 ) and 3,
the return value would be the list ( 3 2 3 )
And here is my code:
ListItem smallElements(ListItem ls, int n){
ListItem small = null;
ListItem result = small;
if(ls == null)
return null;
else{
while(ls!=null){
     if(ls.number <=n){
     result = new ListItem(ls.number, null );
     result = result.next;
     ls = ls.next;
return small;
Like the topic says, i keep getting null returned as a value. I have tried setting small= new ListItem(ls.number, null), and that actually returns the correct list, except that the first number is repeated twice. I would greatly appreciate any assistance.

I am not sure I understand your code. What exactly are those ListItems? It seems to me that you are dealing with single List elements, while the specification says that you are supposed to return a List.
But the main error is that you have two ListItem objects there, which seems to fill the same purpose - only that you use one, and return the other. 'small', which is the one you return, never get set to anything else than null.
I think you should do something like this: make a new, empty list to return
for element in parameterlist
    if number is smaller than n
        add this element to returnlist
return returnlist

Help with linked lists and searching

Hi guys I'm very new to java. I'm having a problem with linked lists. the program's driver needs to create game objects, store them, be able to search the linked list etc. etc. I've read the API but I am really having trouble understanding it.
First problem is that when I make a new game object through the menu when running the program, and then print the entire schedule all the objects print out the same as the latest game object created
Second problem is searching it. I just really have no idea.
Here is the driver:
import java.util.*;
public class teamSchedule
     public static void main (String[]args)
          //variables
          boolean start;
          game game1;
          int selector;
          Scanner scanner1;
          String date = new String();
          String venue = new String();
          String time = new String();
          String dateSearch = new String();
          double price;
          String opponent = new String();
          int addindex;
          List teamSchedLL = new LinkedList();
          String dateIndex = new String();
          String removeYN = new String();
          String venueIndex = new String();
          String opponentIndex = new String();
          start = true; //start makes the menu run in a while loop.
          while (start == true)
               System.out.println("Welcome to the Team Scheduling Program.");
               System.out.println("To add a game to the schedule enter 1");
               System.out.println("To search for a game by date enter 2");

and here is the game class:

     private static double gamePrice;
     private static String gameOpponent;

     //set local variables equal to parameters
     public game(String date, String venue, String time, double price, String opponent)
          gameDate = date;
          gameVenue = venue;
          gameTime = time;
          gamePrice = price;
          gameOpponent = opponent;
     //prints out info about the particular game
     public String toString()
          gameString = "\n --------------------------------------------------------";
          gameString += "\n Date: " + gameDate + " | ";
          gameString += "Venue: " + gameVenue + " | ";
          gameString += "Time: " + gameTime + " | ";
          gameString += "Price: " + gamePrice + " | ";
          gameString += "Opponent: " + gameOpponent + "\n";
          gameString += " --------------------------------------------------------";
          return gameString;
}I'm sure the formatting/style and stuff is horrible but if I could just get it to work that would be amazing. Thanks in advance.

I don't understand your first problem.
Your second problem:

Implementing Hash tables with chaining.

Hi, I'm in a Java data structures class right now and we have a program to do using hash tables. I've read about hash tables and chaining but does anyone know where i can find some examples of code that implement hash tables using chaining. It's all very confusing to me without seeing how it is used in a program.
To give you an idea of what we're doing, the assignment is to create a word processor that looks thru a file and adds different words to the table and also counts how many of each word there is in that file. Keep in mind I'm not asking for the code to this assignment just for some example of how coding hash tables/chaining works.

Simple and probably not complete overview:
Suppose you have an array in which you will store objects.
You take an object, and find a "hash code" for it. You then restrict the hash code in to the range of your array. This gives you the index where you can store your object.
But what if another object is already present at that index?
Different solutions to this exist - such as re-hashing. One solution is "chaining". Instead of storing the object directly at the hashed index - you store a list of objects which hashed to the same location.
When you do a lookup, you first get your hash. You then look at the corresponding location in the array. If you find a list rather than the required object, you walk along the list until you find the object you are looking for.
Of course, with a small array and bad hash distribution, the performance of this solution can degrade fairly quickly.
BTW, in the real world, just use one of the ready made collections in java.util.

How to implement Oracle user/role security with Access front end?

Hi,
We have successfully migrated our Access database tables to Oracle 10g using SQL developer. We've recreated all the users and roles(i.e., access groups) in Oracle and granted rights to tables.
In the Access front end database, in the Database window we have saved linked Oracle tables which replaced the Access tables. The forms, reports, queries run fine with the linked Oracle tables. All the linked table use one ODBC DSN to the Oracle database with the same Oracle user id.
We need to be able to authenticate users into the Oracle database and RE-link the tables based on their own unique user id. By during so we can allow users to use the Oracle standard user id/role and system privileges to control select, update, ect. rights to the database.
I've been able to use the VB code within Access to logon into the database with a unique id, but I have not been able to find out how to RE-link the tables to the unique user id using VB. There should be some way to relink tables dynamically, based on users login into the Access front end.
I don't know a great deal about Access projects, but I do know with SQL server allows login into your Access project and link tables dynamically.
Can someone give me some assistance or point me in the right direction?
Thanks in advance,
Larry

We had one of our programmers here come up with a VB code solution for re-linking table within Access. However the relinking takes 3-4 minutes for 100+ tables.
In an effort to help you understand the situation better, I will attempt to elaborate on the problem:
We have an Access 2003 application which currently has a front end using Access(forms, reports, queries, & VB code) and a MS Access 2003 backend.
We have migrated the backend tables to Oracle. However, we still have a need to maintain the front end in Access, since we have over 60 forms, 40 reports, 200+ queries in Access. Its easy to understand, we have a significant investment in the front end(Obviously, the plan is to migrate the front end also at some future date).
In order to utilized the existing front end, we have to validate and modify the current front end connections to the new Oracle backend. One of the features of Access is that you can "link" tables and save the link for runtime. Each Access table can have its own link which is a separate ODBC/JET connection. As such, each separate link has its own userid/database information.
The other issue with using the Access front-end is that Access utilizes a workgroup file to implement user and group security. The workgroup file contains all the users and which groups the users belong to in Access. Then within Access, you allow users access to object(tables, queries, ect) by their userid and or group. When users open an Access database with Access security enabled, they are required to log into Access. The login is authenticated by the workgroup file. Once, logged into Access, users have rights to Access objects based on their rights granted to their userid and groups they belong. The problem here is that when you remove the linked Access tables and replace them with linked Oracle tables, Access has knowledge about Oracle table rights granted to users; nor would you expect it to.
The dilema is the disconnect between Access and the fact Oracle utilizes a similar but much more sophisticated security model. It creates users and roles(which are similar to Access groups), and again this is independent of Access security.
Our solution was to still use the Access workgroup file security along with the Oracle security model. By using the Access userid and then creating a similar Oracle userid with similar table rights granted in Access, you could apply security within Access and also with the Oracle database.
For example, a user BOB logs into Access via the workgroup file, using VB code, Access then establishes a Oracle connection logining into Oracle using the same unique userid BOB into Oracle.
After connecting and validating user BOB into Oracle, then the Access tables are relinked to Oracle using the user BOB userid and table rights.
This Oracle userid has been granted table rights specific for this userid.This allows the user BOB to use the Access application and still be authenticated into the Oracle database.
The problem with this solution is that the relinking of the saved Access tables takes 3-7 minutes for about 100+ tables. This is not acceptable for users each time they log into the application.
Our current alternative is to use one Oracle userid to login each user, and use Access form restrictions/security to allow/prevent users from updating/viewing data. Obviously, this is not the optimal solution in respect to security, but it at least allows us to control access to the data(via the forms) by using one logon required for each user, and quick startup time for the application.
I understand SQL server does a better job in integration, but we use Oracle which is what I am trying to work with.

How to get values from Hash Table

Hi all,
I have a hash table "lovResults" craeted with following code -
String lovInputSourceId = pageContext.getParameter(SOURCE_PARAM);
Hashtable lovResults = pageContext.getLovResultsFromSession(lovInputSourceId);
values which I can see through SOP are - ******Value of lovResults is{roleid=1000, domainFV=CREATIVE, Role=Account Director}
How can I get the domain value "domainFV=CREATIVE" from hash table in a variable because I have to set this vaue in another field.
Please help me ASAP
Thanks
Amit

Hi Amit ,
Since you are successfully printing the values using sop's , please try this code
Capture the value in controller .
if(oapagecontext.getParameter("domainFV") != null)
String formvalue= oapagecontext.getParameter("domainFV") // ensure hashtable id is correct

How to implement a Copy or Create with Reference scenario

For business objects, you might want to implement a Copy or Create with Reference scenario. The following procedure describes the UI configuration that you need if you want to place a copy button (in our example on an OWL) that starts a quick activity floorplan (on the same BO = Copy, or a different BO = Create with Reference). Pre-requisie in the target BO: The target BO requires a BO element SourceBOID and a Copy action that reads the SourceBO by SourceBOID by query, and copies the elements from the source to the target BO.
The UI configuration in the target floor plan is:
1. Open the QAF floor plan of the target BO (target floor plan).
2. In the DataModel view of the target floor plan, select the Root entry and select Add Data Field from the context menu. Rename the created data element to OBN_OriginBOID.
3. Choose the Controller tap, and select INPORTS and choose ADD INPORT from the context menu. A new in-port is created. Rename the in-port, for example to Copy.
4. In the in-port maintenance form, activate the check box OBN INPORT.
5. Select the namespace of your solution and the target business object.
6. In the input field SELECT OPERATION enter Copy. A new select operation is created. The combination of business object name (including namespace), business object node and operation identifies the in-port and therefore the related floor plan as navigation target.
7. Select the port type package /SAP_BYD_UI/SystemPortTypes.PTP.uicomponent.
8. In the PARAMETERS section of the form, click the ADD button. Maintain the binding of the created parameter to /Root/OBN_OriginBOID. Based on this configuration, the system will transfer the parameter of the in-port to the element in the data model when the OBN is executed.
9. In the Properties view, select the drop-down list box of the property EVENTS u2022 ONFIRE. Scroll down and select the entry u2026 NEW EVENT HANDLER u2026. The system starts the maintenance window for event handlers. Rename the event handler to CopyIn.
10. In the OPERATIONS table of the maintenance window for event handlers, select type: BUSINESS OBJECT OPERATION. In the form below the table select the value CREATE for the input field BUSINESS OBJECT OPERATION TYPE. This operation will create a BO instance in the backend when the OBN is executed.
11. In the OPERATIONS table, create a new operation of type: DATAOPERATION. In the configuration of the data operation, select the operation type ASSIGN, source expression /Root/OBN_OriginBOID and target expression /Root/<BO>/OriginBOID.
12. Create a third operation of type: BUSINESS OBJECT ACTION. Select the Copy action of the target business object and click the BIND button. Note: This action enforces another roundtrip to the backend. The Copy action must be implemented so that it will read the origin BO and copy selected data from the origin to the newly created object.
13. Test the changes in the preview. If no error message is issued, save and activate the floor plan.
The following procedure describes the configuration in the source floor plan (e.g. OWL floorplan ):
1. Open the Source BO OWL floor plan (source floor plan).
2. In the Designer view, place cursor the on the toolbar area and select ADD u2022 APPLICATION-SPECIFIC BUTTON u2022 MY BUTTON from a context menu. Rename the new button to Copy.
3. In the Properties view, select the drop-down list box of the property MENU INFORMATION u2022 NAVIGATION. The system launches the maintenance window for OBN configuration.
4. Select the in-port of the target floor plan by selecting the target business object (with namespace and name) the target business object node and the target operation, and the operation Copy.
5. Choose the navigation style NEWWINDOW.
6. Close the OBN configuration maintenance window by clicking the OK button. The system creates the OBN configuration, an out-port, that is used by the OBN configuration, and an event handler that uses the out-port and that is assigned to the button (see Properties view, EVENTS u2022 ONFIRE).
7. Go to the Controller view and rename the OBN configuration to Copy, the new out port to Copy and the new event handler to CopyOut.
8. Check that the event handler CopyOut fires the out-port Copy.
9. In the Parameters section of the out-port maintenance form, click the ADD button. Maintain the binding of the created parameter as /Root/<BO>/<BO>ID. Based on this configuration, the system will transfer the identifier of the selected source BO to the out-port data structure when the OBN is executed.
10. In the Operations table, select type: FIREOUTPORT. In the form below the table select the out-port CopyOut.
11. Test the changes in the preview. If no error message is issued, save and activate the floor plan.

Hi Dries-
There are no pre-packaged solutions with BADIs since they are, by definition, custom development. If that's the path you need to go down then consider the following high level alternatives:
Incorporate custom code into the BPC Write Back BADI. You can restrict the execution of the BADI using filters on the BADI definition, so that the BADI execution only occurs when a data manager package is called, and only for some defined combination of applications/appsets. Utilized the standard copy/move functions delivered in Data Manager. When the BADI is called, interrogate each record being processed (table CT_ARRAY) and determine if the record has a value you want to process (i.e. save to the target application). Skip any record that has a zero value.
Another alternative is to develop the BADI as custom logic. Data Manager parameters can be picked up in Script Logic and the values can be sent to the BADI by adding parameters. Please see an example of parmater use in the "How To" document for Destination App at:
