I need help with comparing Objects of an ArrayList

Hi,
I am trying to compare a certain variable of objects which are stored in an arrayList.
for example i have a class called AuctionBid(String bidderID, BitSet itemSet, int bidValue)
and i have another class called AuctionBidFactory which creates AuctionBid objects and stores them into an arrayList
I have another Gui class which acts as a user interface where the user can create bids but then i want to compare the itemSet of the AuctionBid which is created by the user to the itemSets of the AuctionBid objects which already exist in the arrayList and if that itemSet does not exist in the arraylist then will add the new AuctionBid to the arrayList.
I have the following method in the AuctionBidFactory which is supposed to compare the itemSets of the AuctionBids in the arrayList and it does not work:
public boolean containsItem(AuctionBid auctionBid) {
          if (auctionBids.contains(auctionBid.itemSet)) {
               return true;
          return false;
where auctionBids is the arrayList where the AuctionBid objects are stored
I hope the information above is enough to see where the problem is.
many thanks

Amit, unfortunately I dont have a different object for the user bids. Basically I just have the AuctionBid(String bidder,BitSet items, int value) and the reason why im using bitSet is that im modelling a combinatorial auction where the bidder can bid on combination of items.
now when the user puts a bid that bid is added to an arrayList of ArrayList<AuctionBid>
then once all the bidings have finished i want to create autoBids for those single items only for which there are no bids. so for example lets say there are 6 items for auction and if there are the following bids in the arrayList:
AuctionBid(bidder1,{1},5)
AuctionBid(bidder2,{5},8)
i want to create autobids as follow:
AuctionBid(autoBid,{0},0)
AuctionBid(autoBid,{2},0)
AuctionBid(autoBid,{3},0)
AuctionBid(autoBid,{4},0)
and then i want to add these created bids to the same arrayList where all the bids are.
but if I use the arrayList.contains() method it will compare the whole objects to each other rather than just comparing the bitSets(items) in each bid.
so i dont know whether i can still do this without overriding the equals() method in the AuctionBid class or not

I need help with a Object Array

I am having trouble and this maybe really simple seeing that I am fairly new to java but I have text that is being broken down in to preset part with those parts stored in Object arrays.
Now I also have a object array inside my object array. Within the second object array are the broken down parts of the text and I want to compare this text with another string so for example this is what I am trying
boolean found = false;
for (int i = 0; i < FirstObjectArray.length ;i++)
     Object[] SecondObjectArray = (Object[]) FirstObjectArray;
     if(SecondObjectArray[0] == "string")
          found = true;
          break;
     else
          found = false;
}Help would be very appreciated.

sharkura said all the OP needs at the moment. I just wanted to clarify a bit why You don't use == 99.999% of the time with objects, and never with String.
I have argued elsewhere in these forums that it is inappropriate to tell anyone that you never use == to compare objects. This has not always been accepted. I have, on rare occasions, known experienced developers to blindly compare two objects with equals(), and cite the professor that taught them, 15 years iin the past, that object references are never compared using ==, but always with equals().
However, the cases where == is appropriate and equals() is not are indeed rare, but not, in my experience, non-existent. In my statement, I probably exaggerated. And String is a case where I can probably accept that you will probably never go wrong with equals(). If the String has been pooled (see String::intern()), you can actually use either. From the javadocs: "*It follows that for any two strings s and t, s.intern() == t.intern() is true if and only if s.equals(t) is true.*"

I just upgraded to CP 5. Need help with drawing objects.

I am trying to put a simple drawing object around a word. Like a square. I can't figure out how to not have any fill, just the outline of the box. Any suggestions? I was able to do this in CP 4.

Hi there
Personally, I'd use a Highlight Box to accomplish this. But that's just me.
Here are the steps for a square drawing object. I'll assume you have already inserted the object and placed it and all you want are instructions for dealing with the fill.
Look inside the properties inspector at the Fill & Stroke section. Click the Fill color and configure Alpha to 0%.

Need help with Calling objects

I have created an object named "user" and I currently have 1 Frame in my program. The first frame is called "LogonFrame" and the second is called "UserDataFrame".
In the main method of the application I declare a "User" object as user and then call LogonFrame to retreive the logon_name and password from the user. The logon_name and password will be placed in the User object to be accessed throughout the application.
When I compile the application I receive the following error message:
Error: (85) variable user not found in class GL2.LogonFrame
*I know that 85 is the line number that the error is located
*GL2 is the name of the package.
Has anyone ever encountered this error before, and if so how can I fix this error.
*Listed below is the code used in the User object if it helps at all.

Need help with class object? Please somoen

hey guys,
It's been few days since i'm working on making a small bingogame program but i'm getting stuck frequantly.
I've different classes, in the main class i'm asking the user to input number of players who would like to play then i'm asking the player's name and how many bingoCards each player wants.
I'm stroing all that info in a BingoPlayer class's array object. But for some reason when i get out from the loop and try to retrive the info from that array it only gives me the last input entry (player's name & number of cards) at any index of the array.
Can please someone tell me how i can store the given information for each player in that object array on different indices of the array?
I'm providing the code where i've the problems:
public class BingoGame
    public static BingoPlayer players[] = new BingoPlayer[5];
    public static void main() throws IOException {
        int numPlayers = 0;
        int numCards [] = new int [5];
        String name [] = new String[4];
        BufferedReader input = new BufferedReader (new InputStreamReader(System.in)); //allows input
// ask for the number players who wants to play
        System.out.print("Please enter the number of players in this game (2-5): ");
        numPlayers = Integer.parseInt(input.readLine());
// make sure the entered value is within range
        while (numPlayers < 2 || numPlayers > 5) {
            System.out.println("Invalid number of players ");
            System.out.print("Please enter the number of players in this game (2-5): ");
            numPlayers = Integer.parseInt(input.readLine());
        System.out.println();
//ask for the names and numebr of cards for entered number of players
// and make sure the number of cards are within the range,
//and assign the players that many cards using the BingoPlayer object
        for (int i = 1; i <= numPlayers; i++) {
            System.out.print("Please enter name of player " + i + " : ");
            name[i] = input.readLine();
            System.out.println();
            System.out.print("Please enter the number of cards (1-5) for player " + i + " : ");
            numCards[i] = Integer.parseInt(input.readLine());
            while (numCards[i] < 1 || numCards[i] > 5) {
                System.out.println("Invalid number of cards for the player " + i);
                System.out.print("Please enter the number of cards (1-5) for player " + i + " : ");
                numCards[i] = Integer.parseInt(input.readLine());
            System.out.println();
            players[i] = new BingoPlayer(name, numCards[i]);
* here it only prints out the information for the last player, instead it should return the information for both of the player
for (int k = 1; k <= numPlayers; k ++) {
System.out.println(players[k]);
//players[k].genCards();
for example if i enter 2 players:
Player1: name: Jami, number of cards 1
Player2: name: Joey, number of cards 2
in the last loop it just prints out :"Joey, 2" 2 times instead of printing out: "Jami, 1" & "Joey, 2"
Please someone help! i really need to complete this within 2 days. Thanks in advance

Without seeing BingoPlayer's implementation, all it
would be would be a guess.
My guess: The name and numCards members of that class
are declared as static, so all instances share the
same values.Thanks it worked, declaring them static was the main probelm..thank you very much

Need Help with Dates

I am printing a calendar and certain events will be helds on certain dates.
One can edit the event if it has not passed the date. Events in the past can be viewed but not edited.
When I query the database the date must be formatted dd-MMM-yy
I am able to get today's date by doing this:
java.util.Date today = new java.util.Date();
String formatString = "dd-MMM-yy";
SimpleDateFormat sdf = new SimpleDateFormat(formatString);
String today_str = sdf.format(today);
My code for printing the calendar: I left out some of the table formatting in the JSP page.
GregorianCalendar d = new GregorianCalendar();
int today = d.get(Calendar.DAY_OF_MONTH);
int month = d.get(Calendar.MONTH);
d.set(Calendar.DAY_OF_MONTH,1);
int weekday = d.get(Calendar.DAY_OF_WEEK);
for(int i = Calendar.SUNDAY; i < weekday; i++)
out.print("<td> </td>");
do {
int day = d.get(Calendar.DAY_OF_MONTH);
out.print("<td>" + day + "</td>");
String formatString = "dd-MMM-yy";
SimpleDateFormat sdf = new SimpleDateFormat(formatString);
//if(event exists on this day
// Get results
// print link for viewing
// if (after today) print link for edit
if(weekday == Calendar.SATURDAY)
out.println("</tr><tr valign=top>");
d.add(Calendar.DAY_OF_MONTH,1);
weekday = d.get(Calendar.DAY_OF_WEEK);
} while(d.get(Calendar.MONTH) == month);
if(weekday != Calendar.SUNDAY)
System.out.println();
The part I need help on is this:
//if(event exists on this day
// Get results
// print link for viewing
// if (after today) print link for edit
I'm looping through each day of the month to print the days. I have the month, day, year as integers. How can I create a date object out of that and compare it to today's date to test if it's before or after today???
All the function in the Date class that I think would do this have been deprecated.

Need Help with Dates
Here is some information about dates:
There are many edible palm fruits, and one of the most widespread and favored of these is the data (Phoenix dactylifera). Dates were cultivated in ancient land from Mesopotamia to prehistoric Egypt, possibly as early as 6000 B.C. Then--as now--dates were a staple for the natives of those dry regions. Much later, Arabs spread dates around northern Africa, and dates were introduced into California by the Spaniards in 1765, around Mission San Ignacio.
The date prefers dry, hot climates, because date fruits are injured at temperatures of 20 degrees F, and the damp climate of the California coast was not favorable for fruit production. In the mid-1800s, the date industry developed in California's hot interior valleys and in Arizona. Now the date industry in the United States is localized mostly in the Coachella Valley, where the sandy soils permit the plants to be deeply irrigated. Today the new varieties, mostly introduced in this century, produce about 40 million pounds of dates per annum, or over 60% of the dates consumed in this country. The rest are imported mainly from Persia. According to one survey, about one million people are engaged entirely in date palm cultivation worldwide.
Hope that helps.

Need help with generics

I have written a java program using jdk1.5. After completing my program I noticed that the compiler was outputting a warning. It tells me that there were a few unsafe operations in my code. Anyway I found out that my code needed to include generics. I was able to figure out how too include some of the generics. I am having trouble with the following:
[javac] /home/paul/Documents/java/PersonalInfo/src/personalInfo/logic/DB.java:105: warning: [unchecked] unchecked conversion

The FN/LNComparator class implements the java.util.Comparator class. I have looked at the generics tutorial on the java.sun.com website. I can't figure out what I replace the <T> with to make the code compile and the warning to go away. I have tried <Comparator> but that just gives me an error that says FNComparator does not take any parameters.
If anyone knows how to fix these warnings let me know
-Hockeyfan

I know how to fix it.
Step 1. Stop writing subject-lines like "Need help with generics". Everyone who starts a topic needs help, that's why people post here!
Step 2. Don't just post the error message, post the relevant code. In [code ][code ] tags of course.
Step 3. Stop watching hockey, it'll stunt your growth
Step 4. Have the FN/LNComparator implement, not the raw Comparator, but Comparator<Object>

Need Help With File Matching Records

I need help with my file matching program.
Here is how it suppose to work: FileMatch class should contain methods to read oldmast.txt and trans.txt. When a match occurs (i.e., records with the same account number appear in both the master file and the transaction file), add the dollar amount in the transaction record to the current balance in the master record, and write the "newmast.txt" record. (Assume that purchases are indicated by positive amounts in the transaction file and payments by negative amounts.)
When there is a master record for a particular account, but no corresponding transaction record, merely write the master record to "newmast.txt". When there is a transaction record, but no corresponding master record, print to a log file the message "Unmatched transaction record for account number ..." (fill in the account number from the transaction record). The log file should be a text file named "log.txt".

Much help is appreciated. Please help.

From the output, it looks like one problem is just formatting -- apparently you're including a newline in log entries and not using tabs for the newmast output file.
As to why the numbers are off -- just from glancing over it, it appears that the problem is when you add multiple transaction values. Since account.combine() is so simple, I suspect that you're either adding creating transaction objects incorrectly or not creating them when you should be.
Create test input data that isolates a single case of this (e.g., just the Mary Smith case), and then running your program in a debugger or adding debugging code to the add/combine method, so you can see what's happening in detail.
Also I'd recommend reconsidering your design. It's a red flag if a class has a name with "Create" in it. Classes represent bundles of independant state and transformations on that state, not things to do.

I need help with a VB Application

I need help with building an application and I am on a tight deadline. Below I have included the specifics for what I need the application to do as well as the code that I have completed so far. I am having trouble getting the data input into
the text fields to save to a .txt file. Also, I need validation to ensure that the values entered into the text fields coincide with the field type. I am new to VB so please be gentle. Any help would be appreciated. Thanx
•I need to use the OpenFileDialog and SaveFileDialog in my application.
•Also, I need to use a structure.
1. The application needs to prompt the user to enter the file name on Form_Load.
2. Also, the app needs to use the AppendText method to write the Employee Data to the text file. My project should allow me to write multiple Employee Data to the same text file. The data should be written to the text file in the following format (comma
delimited)
FirstName, MiddleName, LastName, EmployeeNumber, Department, Telephone, Extension, Email
3. The Department dropdown menu DropDownStyle property should be set so that the user cannot enter inputs that are not in the menu.

Need help with my usecase based on transient ViewObject

I am using 11.1.1.4.0 Jdev version. I need help with my usecase.Been trying it for 2 days but couldn't figure out the issue.
I have a transientVO . In this VO Rows will be populated programmatically. CountryId is an attribute of this VO. I have created a viewAccessor "CountriesVA" from Country VO of HR schema.
I have a LOV for the countryId which is based on this VA ,getting countries from CountryTable.
This is the model part which works fine.
Before the page load i have called a method to create a row for this transientVO.Once the row is created i can see the SOC in my page which i have created as below.
Now i want to insert a row in the transientVO if user selects a country and restrict duplicate entry . (As One row is already created 1st time there will be no rows created.after that rows will be inserted)
The issue is :: Suppose there are 2 countries. A & B .When user does the following actions :
Insert A . Done //as 1st entry
Insert B . Done //as 1st time entry
Insert A . duplicate not inserted
Insert B . getting inserted // the bug.

I read the reply from Andrejus Baranovskis and thought of studying and implementing that in my useCase.Well it worked . I implemented the same Logic but rowIteration was done in AppModule.

9.7.6 What You May Need to Know About Programmatic Row Set Iteration
The problem is solved ,the above links helped me solve the problem.
what i did is i have created a method in appmodule to iterate rows and all the method y operation bindings and my logic works fine ....
MY Advice to all Adf developers ,though i am not an expert but i can assure you to follow the above process for rowIteration.If you use the iterator binding in the manage bean to navigate the rows u'll face issues which are unexpected.
In AppModule :::::
    public boolean createRow(String oldValue,String newValue){
     System.err.println(oldValue+""+newValue);
      ViewObjectImpl vo=getViewObj1();
      boolean duplicate=false;
      if(oldValue!=null){
      RowSetIterator iter = vo.createRowSetIterator(null);
      System.err.println("iterating rows ");
         while (iter.hasNext()) {
             Row r = iter.next();
             System.err.println(iter.getRangeIndexOf(r)+" row is "+r.getAttribute("CountryId"));
             if(r.getAttribute("CountryId").toString().equals(newValue)){
                 duplicate=true;
                 break;
             // Do something with the current row.
         // close secondary row set iterator
         iter.closeRowSetIterator();
      return duplicate;
In ManageBean :::::
    public void countryIdVC(ValueChangeEvent valueChangeEvent) {
        // Add event code here...
        String oldValue=null;
       System.err.println("Old Value"+valueChangeEvent.getOldValue());
          setEL("#{bindings.CountryId.inputValue}", valueChangeEvent.getOldValue());
          if(evaluateEL("#{bindings.CountryId.attributeValue}")!=null)
