New to Java and need help with this program..please!
I'd really appreciate any helpful comments about this program assignment that I have to turn in a week from Friday. I'm taking a class one night a week and completely new to Java. I'd ask my professor for help, but we can't call him during the week and he never answers e-mails. He didn't tell us how to call from other classes yet, and I just can't get the darn thing to do what I want it to do!
The assignment requirements are:
1. Change a card game application that draws two cards
and the higher card wins, to a Blackjack application
2. Include a new class called Hand
3. The Hand class should record the number of draws
4. The application should prompt for a number of draws
5. The game is played against the Dealer
6. The dealer always draws a card if the dealer's hand total is <= 17
7. Prompt the player after each hand if he wants to quit
8. Display the total games won by the dealer and total and the total games wond by the player after each hand
9. Display all of the dealer's and player's cards at the
end of each hand
10. Player has the option of drawing an additional card after the first two cards
11. The Ace can have a value of 11 or 1
(Even though it's not called for in the requirements, I would like to be able to let the Ace have a value of 1 or an 11)
The following is my code with some comments about a few things that are driving me nuts:
import java.util.*;

}Thank you so much for offering to help me with this Jamie! When I tried to call change value using:
Card dealer = (d.changeValue());
I get an error message saying:
Incompatible types found: int
required: Card
I had my weekly class last night and the professor cleared up a few things for me, but I've not had time to make all of the necessary changes. I did find out how toString worked, so that's one question out of the way, and he gave us a lot of information for adding another class to generate random numbers.
Again, thank you so much. I really want to learn this but I'm feeling so stupid right now. Any help you can give me about the above error message would be appreciated. -
Date Validation problem in form with report
Hi,
I am stuck on this date validation issue in a form with report that I am working on-
I have an Active_date_start and an Active_date_end field. I want to validate the form in such a way that if the user enters the Active_date_end < active_date_start then it should error out appropriately asking to change the active_end_date . Also another problem is that the changes are made to the active_date_end they should reflect in the table. How do I accomplish this.
Appreciate all the help offered.
Thanks.Hi,
Thanks for the code.Now the APPLY CHANGES works fine except that it throws an error when I change the end date to a date which is less than the start date . So it does show me my error and does not go further but also shows me the error -
Invalid PL/SQL expression condition: ORA-06550: line 1, column 29: PLS-00306: wrong number
or types of arguments in call to 'NVL' ORA-06550: line 1, column 7: PL/SQL: Statement
ignored Invalid PL/SQL expression condition: ORA-06550: line 1, column 29: PLS-00306:
wrong number or types of arguments in call to 'NVL' ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
I looked up the error number and it says its a generic error type where the error can be found on the line number specified. But in this case how and where do I look for the error line?. This is the code I am using-
DECLARE
vACTIVE_DATE_START DATE;
vACTIVE_DATE_END DATE;
BEGIN
vACTIVE_DATE_START := TO_DATE(:P4_ACTIVE_DATE_START, 'DD/MM/YYYY');
vACTIVE_DATE_END := TO_DATE(:P4_ACTIVE_DATE_END, 'DD/MM/YYYY');
IF vACTIVE_DATE_END < vACTIVE_DATE_START THEN
RETURN 'End date is before start date';
ELSE
RETURN NULL;
END IF;
END;
My base table has the active_date_start as NOT NULL. Now I have the exact same code for APPLY CHANGES
in other form and it works fine not giving the above error. I am at a loss to know how I can get rid of the error.
Any suggestions!.
Thanks in advance,

Problem sending form with fmt:message key=" " / tag system and jsp code
I have developt my new web page using jsp. I have done a booking form, please se below here. There are two pages, bookings.jsp and booking_sent.jsp. The page has 6 different languages so i have also used the <fmt:message key=" " /> tag system for each language.
The problem i have is when i send the form it opens a page where you only see all the tags, no text at all. For more information follow this link and try out the form;
http://www.neptunediving.com/neptune/general/bookings.jsp/
When you fill out the form and click send you should come to booking_sent and you do but the page is only full of tags, no text. Booking_sent looks exactly the same as bookings, except the header so why should not this work. I have tried everything but i cannot solve this problem. So i wonder if there is anybody out there who can help me with this?

Nope, can't delete posts on this forum,
I have developed my new web page using jsp. I have done a booking form,
There are two pages, bookings.jsp and booking_sent.jsp.
The page has 6 different languages so i have also used the <fmt:message key=" " /> tag system for each language.
The problem i have is when i send the form it opens a page where you only see all the tags, no text at all.
For more information follow this link and try out the form; http://www.neptunediving.com/neptune/general/bookings.jsp/
When you fill out the form and click send you should come to booking_sent and you do but the page is only full of tags, no text. Booking_sent looks exactly the same as bookings, except the header so why should not this work. I have tried everything but i cannot solve this problem. So i wonder if there is anybody out there who can help me with this?
Tried going to that URL and got an error page served by Apache Webserver
Maybe you haven't got the correct connector going between the webserver and the application server? -
New To Java Coding, Help NEEDED With a little script
Well im just working on a script with an open uni course im doing, ive dont the script i was asked to do, but i was wondering if i could expand it abit more
* The DaylesGod class implements an application that
* simply prints "Dayles God!" to standard output.
class DaylesGod {
public static void main(String[] args) {
System.out.println("Dayle is GOD!"); // Display the string.
}thats what i have at the moment, i use cmd-cd C:\java
C:\java>java DaylesGod
Dayle is GOD
I was wondering if i could get it to display diffrent messages on diffrent lines? e.g
* The DaylesGod class implements an application that
* simply prints "Dayles God!" to standard output.
class DaylesGod {
public static void main(String[] args) {
System.out.println("Dayle is GOD!"); // Display the string.
System.out.println("Dayle is GOD!");
System.out.println("Dayle is GOD!");
}Dayle wrote:
Could you please give me an example of what that may look like please?
//New Wow
class Wow { //File Name
public static void main(String[] args) {
System.out.println("Wow");
System.out.println("Wow");
}This code executes fine in Jcreator, but only once, it wont type ''Wow'' Twice? Not to sure what to do, it wont run in cmd properly, want multiple ''Wows'' on seprate lines. If possible? Thank you :) and i will get in touch with shrink ha.That should print
Wow
WowAre you sure you're not having a problem with Jcreator or whatever you're viewing the output with? You might try executing this from the command line. There's no reason you can't do that.
Remember, System.out.println(x) is equivalent to System.out.print(x + '\n'). -
Problem close form with upper-right cross
Hi, I am having a problem with a form in oracle 10gR2.
The form was made with Oracle designer and now when the user click on the upper-right form cross it's not closed. The user must to click on the parent form and close it.
Thanks.I might add that trigger (when-window-closed) but I'm looking that in the application there are other forms that not include that trigger, however that forms are closed through the upper-right cross.
It seems like there was a parameter or property in generator time. I don't know. All the applications forms have been created in the same way.
Thanks, Pavan.

Problems submitting form with Adobe Reader X?
Our agency created a PDF fillable form, and recently three respondants using Adobe Reader X (on PCs) have contacted us to say that the submit button is not working and they are unable to save the contents of the form to a file on their computer. The Forms Central Forum had said Adobe 8.0 or higher would support the fillable form, so we are surprised to be running into this. Has anyone else encountered this problem and found the solution? Is there a step we are missing? Thank you!
@melissasnider : make sure that the form filler are using Adobe Acrobat, Adobe Reader or Acrobat Mobile to fill up the form. Any other PDF viewers doesn't support the submission functionality. More information can be found here : http://forums.adobe.com/docs/DOC-2653.
Hope this helps

Use Formule on FORM with REPORT - result stored at table
Hi all,
What is the best solution for?
I have region with FORM WITH REPORT on the same PAGE.
Values stored at table INFO with column ID, MYDATE, TIME_START_HOUR, TIME_START_MIN, TIME_END_HOUR, TIME_END_MIN, SUM1, SUM2
ITEMS on the form:
P1_ID (hidden)
P1_MYDATE (date picker)
P1_TIME_START_HOUR (select list)
P1_TIME_START_MIN (select list)
P1_TIME_END_HOUR (select list)
P1_TIME_END_MIN (select list)
P1_SUM1 (hidden)
P1_SUM2 (hidden)
After user fill in MYDATE, TIME_START_HOUR, TIME_START_MIN, TIME_END_HOUR, TIME_END_MIN then I need proces for calculation SUM1 en SUM2. Result stored (one record) at table INFO.
Report shows all columns. User had possibility to update the record
Formule:
Select
(CASE
when to_char(mydate,'DY','nls_date_language=dutch') in ('ZA','ZO')
THEN substr(to_timestamp (mydate||':'||TIME_END_HOUR||':'||TIME_END_MIN ||':00','DD-MM-YY:HH24:MI:SS') -
to_timestamp (mydate||':'||TIME_START_HOUR||':'||TIME_START_MIN ||':00','DD-MM-YY:HH24:MI:SS') -
(interval '00 00:00:00' day to second)
,12,5)
ELSE '08:00'
END) SUM1,
(CASE
when to_char(mydate,'DY','nls_date_language=dutch') in ('ZA','ZO')
THEN substr(to_timestamp (mydate||':'||TIME_END_HOUR||':'||TIME_END_MIN ||':00','DD-MM-YY:HH24:MI:SS') -
to_timestamp (mydate||':'||TIME_START_HOUR||':'||TIME_START_MIN ||':00','DD-MM-YY:HH24:MI:SS') -
(interval '00 04:00:00' day to second)
,12,5)
ELSE '04:00'
END) SUM2
FROM INFO
where id=:ID
What is the best way for the calculation: computation or processes or etc? The calculation after or before user push button(New:create button of Update:Apply Changes)?
How to fill the answer (SUM1 and SUM2) at table INFO?
Thanks WalterI have something similar I use:
DECLARE
str_day VARCHAR2(10);
dt_indx DATE;
db_dt_indx VARCHAR2(20);
str_st_tm VARCHAR2(20);
dt_st_tm DATE;
db_st_tm VARCHAR2(20);
str_ed_tm VARCHAR2(20);
dt_ed_tm DATE;
db_ed_tm VARCHAR2(20);
shft_flag NUMBER;
BEGIN
str_day := :P1050_DATE_MM || '/' || :P1050_DATE_DD || '/' || :P1050_DATE_YYYY;
dt_indx := to_date(str_day, 'MM/DD/YYYY');
db_dt_indx := to_char(dt_indx, 'MM/DD/YYYY');
str_st_tm := str_day || ' ' || :P1050_TIME_IN_HH || ':' || :P1050_TIME_IN_MI || ' ' || :P1050_TIME_IN_AM;
dt_st_tm := TO_DATE(str_st_tm, 'MM/DD/YYYY HH:MI AM');
str_ed_tm := str_day || ' ' || :P1050_TIME_OUT_HH || ':' || :P1050_TIME_OUT_MI || ' ' || :P1050_TIME_OUT_AM;
dt_ed_tm := TO_DATE(str_ed_tm, 'MM/DD/YYYY HH:MI AM');
--Alter date if night shift
SELECT NVL(:P1050_NIGHT_FLAG,0) into shft_flag from dual;
IF dt_ed_tm < dt_st_tm THEN
dt_ed_tm := dt_ed_tm + 1;
END IF;
db_st_tm := to_char(dt_st_tm + shft_flag,'MM/DD/YYYY HH:MI AM');
db_ed_tm := to_char(dt_ed_tm + shft_flag,'MM/DD/YYYY HH:MI AM');
end;You'll need to modify it for your page variables. -
Open new window in the same form
Hi
I created a form with 6 records displayed. I have a check box for each record. I would like to select a record and make the check box checked. Once I check a checkbox I would like to automatically open a new window in the same form with further details of the checked record. Could you please help me how I could work on this.Dear you have to create relation between the blocks then you can achieve this like:
1) Create two canvases in your form (canvas1 and canvas2).
2) Create a window in your form with name Window2 now you have two windows (Window1 and Window2).
3) now set the property 'Primary Canvas' of each window (Window1 = Canvas1, window2 = Canvas2)
4) Now create database block of you main table with (CAT, NAME, DEPT) fields and select the Canvas1 in the layout wizard.
5) Create another database block with same table but this time select only 3 fields (CAT,SAL, DATE) and at the time of creation mention relation between blocks in the Data block wizard (block1.cat = block2.cat) and select the Canvas2 in the layout wizard.
6) Now create check box field name MASTER_CHBOX in first block and set Database Item property no of this check box item and set the Value When Checked property to Y and N for Value When unChecked.
7) Create a trigger on CheckBox Item and paste below code in it.
if :MASTER_CHBOX = 'Y' then
show_window('WINDOW2');
go_item('SAL');
end if;
Regards.

Java 6 causing problems with Forms 10.1.2.0.2
I recently installed Sun Java 6 JRE to my Windows XP machine - I have previously been using Java 5 JRE (1.5.0_09).
When I run my Forms applications from any of our appservers (10.1.2.0.2) (i.e. dev, test, prod) I can get by the login no problem but then get presented with a 'blank' browser window. I say 'blank' because the menu and status bar are present but no forms are displayed.
In the Java console (tracing set at level 5) I see the following error ...
network: Connecting http://dbdev.kelman.com:7780/forms/lservlet/;jsessionid=ac1d027f30d62f783e1e32bd4b9295bce539576dad6f.e3aNbxiTbNuMe38Kah0Sb34Pa3n0n6jAmljGr5XDqQLvpAe with cookie "oracle.uix=0^^GMT-7:00"

I uninstalled Java 6 and then was able to run the web forms just fine.
I reinstalled Java 6 and I'm back to the same problem.
Anyone run across this ?

nullThis is for the benefit of everybody who are trying to run Forms 10g on the web with Oracle Application Server 10.1.2.0.2 and JRE/JDK 1.6.
Technically speaking Oracle Support's claims of not being able to certify Forms 10g on Java 1.6 has been due to the way JRE/JDK behaviour which has been changed from 1.6 onwards. Aparently from Java 1.6 onwards, there is a check for all the imported files while classes are being loaded. Although some are not needed by forms they are still checked and an error occurs if they are not present (Note: 748324.1).
The solution to the problem is to apply the patch 10.1.2.3 (https://updates.oracle.com/ARULink/PatchDetails/process_form?patch_num=5983622) which is about 1.7Gb for Linux-x86 platform.
The underlying issue is the way FRMALL.JAR file not having the class oracle.bali.share.sort.StringComparator. Aparently from 10.1.2.3 onwards, Oracle have included this file in the FRMALL.JAR file as a standard bundle, which resolves the bug and completes the java archive.
Alternatively, you may be able to try the one off patch 7384879 (FORMS 10.1.2.3 JAR FILE EXPIRE JANUARY 2009) which is about 4.6Mb from which you can extract the FRMALL.JAR file and replace the original file in the iAS installation.
Though I have not tested this personelly, this could be a faster way out of the problem. -
Scrollbars problem when running a form with Sun Java instead of Jinitiator
Hi All;
Our forms are configured to run with the Sun Java instead of
Jinitiator; functionality wise everything works fine, but when running
the forms on the web there are 2 extra scrollbars
(one vertical and one horizontal) in addition of the browser scrollbar.
Note: This is does not happen when running the same form with Jinitiator (same configurations)
Anyone encountered this situation or has an idea how to to get ride of the extra scrollbars ???
Thanks.Thanks for your replay.
I was able to make all forms working without scrollbars when running form developer at the desktop (windows os) without scrollbars
but when I run them at the application server (Linux Red Hat 3 Enterprise), scrollbars are still there.
I tried your suggestion but did not help
here is the formsweb configuration

height=575
form=xxxxx.fmx

The window get maximized at when-new-form-instance.
Does it has to do with the canvas or window height and width at the design time????
Thanks.
