Need help with writing an equation in java

Hey, does anybody know how to write x - ((x^3)/6) in java.
Thats x to the power 3
Thanks

google "java.lang.Math pow" for information on the power method. beyond that, it should be pretty straightforward

Need help with writing a rule

Need help with some rules. I want to book a number to a specific Entity at a Specific Custom 4 only. I don't want this formula to work at all C4 levels. How can this be done?
for example if Entity is "XBM1123" and we use C4 for tracking and the tracking level I want to book it to is IMPORT, how can this be done for a specific account 4400221
I have my formula as
If pov_value = "<Entity Currency>" or pov_value = "<Entity Curr Adjs>" Then
If HS.Entity.Member = "XBM1123" or HS.Custom4.Member = "IMPORT" then
HS.EXP "A#4400221= A#4521111 + A#3526644 + A#635210"
End If
End if
this did not work. I got hte following error
Calculate started.<BR>Error executing VBScript Microsoft VBScript runtime
error, Line 259:Object doesn't support this property or method:
'HS.Custom4.Member'.<BR>Calculate finished.<BR>Error executing
VBScript %0.
I then changed it to the below and it still did not work
If pov_value = "<Entity Currency>" or pov_value = "<Entity Curr Adjs>" Then
If HS.Entity.Member = "XBM1123" then
HS.EXP "A#4400221.C4#IMPORT= A#4521111 + A#3526644 + A#635210"
End If
End if
error
Invalid Custom1 member
specified for this function.
Invalid Destination specified for this function:
A#4400221.C4#IMPORT.

You are close.
Try:
If pov_value = "<Entity Currency>" or pov_value = "<Entity Curr Adjs>" Then
    If HS.Entity.Member = "XBM1123" then
       HS.EXP "A#4400221.C4#IMPORT= A#4521111.C4#IMPORT + A#3526644.C4#IMPORT + A#635210.C4#IMPORT"
    End If
End if
or replace IMPORT with with Top_C4 or what ever member you need to copy to C4#IMPORT.
Rule of thumb, to be on the safe side and for most simple calcs, is if you mention a dimension on the left side, you need to define it on the right side as well.

Need help with writing a query with dynamic FROM clause

Hi Folks,
I need help with an query that should generate the "FROM" clause dynamically.
My main query is as follows
select DT_SKEY, count(*)
from *???*
where DT_SKEY between 20110601 and 20110719
group by DT_SKEY
having count(*) = 0
order by 1; The "from" clause of the above query should be generated as below
select 'Schema_Name'||'.'||TABLE_NAME
from dba_tables
where OWNER = 'Schema_Name'Simply sticking the later query in the first query does not work.
Any pointers will be appreciated.
Thanks

Remember that anything inside quotes is case-sensitive. Is the owner really "Schema_Name" with a capital S and a capital N, and 8 lower-case letters?
Simply sticking the later query in the first query does not work.Right; the table name must be given when you compile the query. It's not an expression that you can generate in the query itself.
Any pointers will be appreciated.In SQL*Plus, you can do something like the query bleow.
Say you want to count the rows in scott.emp, but you're not certain that the name is emp; it could be emp_2011 or emp_august, or anything else that starts with e. (And the name could change every day, so you can't just look it up now and hard-code it in a query that you want to run in the future.)
Typically, how dynamic SQL works is that some code (such as a preliminary query) gets some of the information you need to write the query first, and you use that information in a SQL statement that is compiled and run after that. For example:
-- Preliminary Query:
COLUMN     my_table_name_col     NEW_VALUE my_table_name
SELECT     table_name     AS my_table_name_col
FROM     all_tables
WHERE     owner          = 'SCOTT'
AND     table_name     LIKE 'E%';
-- Main Query:
SELECT     COUNT (*)     AS cnt
FROM     scott.&my_table_name
;This assumes that the preliminary query will find exactly one row; that is, it assumes that SCOTT has exactly one table whose name starts with E. Could you have 0 tables in the schema, or more than 1? If so, what results would you want? Give a concrete example, preferably suing commonly available tables (like those in the SCOTT schema) so that the poepl who want to help you can re-create the problem and test their ideas.

I am writing a program that is a file sharing program where i read in bytes from a socket in a BufferedReader into a char[]. Then i want to write to a file using FileOutputStream which only lets me write with a byte[]. Is there a way to read in the info into a byte[] rather a char[]?

may be this code helps

Need help with adding arrays to invoice.java please willing to pay?

Using your Invoice class created in lab02, write a client program that allows the user to input three Invoice objects into an array of Invoice objects. After you have inputted all of the invoices, print a heading and then output all of the array elements (Invoice objects) by calling the method from your Invoice class that displays all of the data members on a single line using uniform field widths to insure that all Invoice objects will line up in column format (created in Lab04). At the end of the loop, display the calculated total retail value of all products entered in the proper currency format.
Example of possible program execution:
Part Number : WIDGET
Part Description : A fictitious product
Quantity : 100
Price          : 19.95
(etc.)
Example of possible output
Part Number          Part Description          Quantity          Price     Amount
WIDGET          A fictitious product     100          19.95     199.95
Hammer               9 pounds          10          5.00     50.00
(etc.)
Total Retail Value:                                   249.95

HELP!!! Need help with using DOS comds from Java

I am trying to run ftp in DOS by using the following code, only its not working, when I run the program it opens the DOS window but nothing happens, it does run but returns me two the command prompt straight away. If anyone can help it would be great, thanks in advance.
import java.io.*;
class DosCmd{
public static void main(String [] args){
try{
Runtime rt = Runtime.getRuntime();
Process child = rt.exec("start ftp /c ftp 172.20.2.134");
child.waitFor();
catch(IOException io){}
catch(InterruptedException e) {}

I agree with ChuckBing,
there is no option /c for ftp as far as I know (http://www.microsoft.com/windows2000/en/server/help/ftp.htm), why don't you try "start ftp 172.20.2.134"? What should this "/c" option do?
Hope this helps,

Need help with jsp that uses a java program

Hi, sorry for my english but i am italian.
I've got a problem: i use java builder and i have a java program(this program has got a main and includes libraries) about graphich on tree, this program visualizes these trees and makes operations on these.
Now i must use JSP so that a client can see this program (this program is on the server) and can interact with it.
I can't use applet.I must use only jsp.
Who can tell me how can i start???
Thanks.

If you are not allowed to use an applet, then you are limited by what can be achieved with HTML in a browser.
You would have to figure out how to render it with HTML, then program your jsp to write out this html programatically.

Need help with writing a program

how would i write a program with one integer variable i that outputs the numbers 1 to 5 on one line. The program may use the System.out.println to only ouput either the variable i or a space (" ").

it's in the section about "Control Flow Statements":

move : BKPF-BUDAT to i_END_DT,
         BSEG-ZZITY to i_ZZITY.
select single * from z-table into <workarea>-ZTFICO_ZZITY_V ZTFICO_ZZITY_V

Help with writing and retrieving data from a table field with type "LCHR"

Hi Experts,
I need help with writing and reading data from a database table field which has a type of "LCHR". I have given an example of the original code but don't know what to change it to in order to fix it and still read in the original data that's stored in the LCHR field.
Basically we have two Function modules, one that saves list data to a database table and one that reads in this data. Both Function modules have an identicle table which has an array of fields from type INT4, CHAR, and type P. The INT4 field is the first one.
Incidentally this worked in the 4.7 non-unicode system but is now dumping in the new ECC6 Unicode system.
Thanks in advance,
C
SAVING THE LIST DATA TO DB
DATA: L_WA(800).
LOOP AT T_TAB into L_WA.

             SEQNR type ZDBTAB-LINENUM,

Select the data.
SELECT linenum rawdata from ZDBTAB into table T_DATA
     WHERE repid = w_repname
     AND rundate = w_rundate
     ORDER BY linenum.
Populate calling Internal Table.
LOOP AT T-DATA.
APPEND T_DATA to T_TAB.
ENDLOOP.

Hi Anuj,
The unicode flag is active.
When I run our report and then to try and save the list data a dump is happening at the following point
LOOP AT T_TAB into L_WA.
As I say, T_TAB consists of different fields and field types whereas L_WA is CHAR 800. The dump mentions UC_OBJECTS_NOT_CONVERTIBLE
When I try to load a saved list the dump is happening at the following point
APPEND T_DATA-RAWDATA to T_TAB.
T_DATA-RAWDATA is type LCHR and T_TAB consists of different fields and field types.
In both examples the dumps mention UC_OBJECTS_NOT_CONVERTIBLE

Help with writing a formula

Hi all,
I am creating a report, and need help with writing a formula...
I am creating a report that shows how many visits/touches our reps have made to various grade accounts. It is broken down by calendar week, and I currently have a weekly "goal" number set that the reps have to meet. That "goal" number increases each week to keep a running total. (example: week 1: 7, week 2: 14, week 3: 21)
I have created some different formulas and one is this:
SUM("Activity Metrics"."# of Activities" BY Date."Calendar Week")
What this shows me is how many "visits" there are per calendar week to customers, however it show me the total for all reps per week.
What I need is that total to show, but totaled for each rep individually.
What I was trying is this:
SUM("Activity Metrics"."# of Activities" BY Date."Calendar Week") BY Employee."Employee Name"
But...I keep getting an error.
Any suggestions?
I have the reporting book by Lairson, and have been referring to it...but my brain at this point is fried.
Thanks in advance for any help...(please forgive...I am new to OnDemand, and I am sure this is easy)

Thanks for helping!
I created this formula as a column: SUM ("Activity Metrics"."# of Activities" BY Date."Calendar Week"), it is called "total number of visits per week" and it shows the totaled number of visits that all the reps have done per calendar week. For example: Week 1: 10 visits, Week 2: 37 visits, Week 3: 20 visits.
What I would like to do is take that column and break it down further, to show instead how many visits per week by sales rep there have been
So what I was trying was to take the "total number of visits per week" (SUM ("Activity Metrics"."# of Activities" BY Date."Calendar Week")) and use "Activity Owner" (Employee."Employee Name") to break it down further.
What I need to use is the total number of visits each rep has per calendar week.
I think I am getting the error because you can't use "BY" twice in a formula?

Im DROWNING! need help with a simple java assignment! plz someone help me!

i need help with my java assignment, with validating a sin number. easy for must who know java. im drowning... please help!

You will need to store each digit of the social insurance number in a field of its own. To validate the entry you will:
1. Multiply the 2nd, 4th, 6th and 8th digit by 2.
2. If the product of any of the four multiplications result in a value greater than 9, add the two resulting digits together to yield a single-digit response. For example 6 * 2 = 12, so you would add the 1 and the 2 to get a result of 3.
3. Add these four calculated values together, along with the 1st, 3rd, 5th, and 7th digits of the original number.
4. Subtract this sum from the next highest multiple of 10.
5. The difference should be equal to the 9th digit, which is considered the check digit.
Example of validating S.I.N. 765932546
1st digit 7
2nd digit (6*2 =12 1+2=) 3
3rd digit 5
4th digit (9*2 = 18 1+8 =) 9
5th digit 3
6th digit (2*2 = 4) 4
7th digit 5
8th digit (4*2 = 8) 8
Total 44 next multiple of 10 is 50
50-44 = 6 which is the 9th digit
Therefore the S.I.N. 765932546 is Valid
********* SIN Validation *********
