A little bit of help with arrays
Hi guyz
I have a problem regarding reading and processing element of an array. I have a "Reference Base Generator" and for example I generate a sine wave. Then I use "Get waveform components" to get the data from the graphic, after this i have a 1-D array of data (right?) at the output of the "Get waveform component' bloc. I need to read every element, process it and then send it as a value further to a function input. So, how can i get every element of that array and send it further ?
I hope I was clear with my problem.
It would be great if you could provide me with some help.
Thanks alot,
Andrei_L.

Need a little bit of help with substring...
Im very new at java programming, and need a bit of help with a problem:
Here is what I have:
System.out.print("Enter a string : ");
Scanner scan = new Scanner (System.in);
stringy = scan.nextLine();
Now I want to split the string "stringy" like this: h:hi:hip:hipp:hippo
I know this uses substring, but I can't figure out how to do it.
Any help would be great, thanks!I know about the length method, what I dont knowis
how to use the length and substring methodstogether
to solve the problem i mentioned initially. There are three ingredients to perform this task:
- String.length()
- String.substring(int start, int end)
- for-statement:
http://java.sun.com/docs/books/tutorial/java/nutsandbo
lts/for.html
Pseudo code:IN <- input String from user
LOOP FROM 0 -> IN.length()
print IN.substring(?, ?)
print ":"
END LOOP
Remember, Im very new. ;)Remember that by just handing you the solution, you
will learn far less than finding things out by
yourself.
; )Thanks a lot, i should be able to figure it out froom the pseudo code. :) -
Little bit of help with the duplication process needed
Hi
I trying to duplicate a database from one server to a remote server. They are both running windows server 2003 (my first problem) , the primary server is running oracle 11gR1 and the (hopefully) receiving server is running 11gR2(is that going to be a problem?) and I'm a little stuck on some parts of the process.
The book I'm using says to edit the listener.ora file to include a SID_DESC of the remote database. Here is my listener.ora file with the modifications
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = test.host.local)(PORT = 1521))
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = CGARDMSTR)
(ORACLE_HOME = G:\app\administrator\product\11.1.0\db_1)
(PROGRAM = extproc)
(SID_DESC =
(GLOBAL_DBNAME = CGARDMSTR)
(ORACLE_HOME =G:\app\administrator\product\11.1.0\db_1)
(SID_NAME = CGARDMSTR)
*(SID_DESC* *=*
*(GLOBAL_DBNAME* *=* cgard)
*(ORACLE_HOME* *=F:\oracle\product\11.2.0\dbhome_1)*
*(SID_NAME* *=* cgard)
(bold is what i added)
it then said to chnage my tnsnames.ora
CGARD =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = test.host.local)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = cgard)
CGARD5DE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = test.host.local)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = CGARD5DEV)
CGARDMST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = test.host.local)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = CGARDMSTR)
cgard =
*(DESCRIPTION =*
*(ADDRESS = (PROTOCOL = TCP)(HOST = live.host.local)(PORT = 1521))*
*(CONNECT_DATA =*
*(SERVER = DEDICATED)*
*(SERVICE_NAME = cgard)*
I changed the local domain to host for business reasons
The next step was to create a initialization parameter file which I am guessing is a pfile and hopefully not a spfile. It then says to only enter one param db_name and the conversion params if the filesystem is diffrent. Problem is I don't know what to do with this file, if I am suppose to switch the second database to this file then surly I would need some more params? Anyway thats the first of many questions.
When I try to run through the rman commands it describes it also trips up:
RMAN> connect auxiliary sys/*********@live.host.local
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-04006: error from auxiliary database: ORA-12170: TNS:Connect timeout occurr
ed
The other database is up and connectable via sqldevloper so I'm guessing it was my configuration of listener and tnsnames
Ok to reiterate my questions are:
1) what needs to be in the pfile I create for the database thats going to receive the backup and what do I do with that file when I have made it?
2) I am pretty sure my listener and tsunamis config is completely wrong so can I have some pointers on fixing that?
3) Was the reason I could not connect to the receiving database my tns and listener config or is it something else?
Quite a few other questions but untill I know some more about the above I doubt I will be able to ask properly.
Also if this helps the book I am using is Expert Oracle Database 11g Administration and the page is 835(the method that begins on that page) and I am willing to write out the whole method if you need more details.
Oh and if you havent figured it out I am very new to this so if some of this sounds very wrong or just stupid just say what I need to change and I will get right on it.
Thanks

I did issue the commands:

So I am not quite sure what it wants. I read somewhere about a password file but I don't understand how it will help, also most things I have looked at wernt clear on how to do it. I took a stab anyway:
G:\app\administrator\product\11.1.0\db_1\BIN>orapwd file=orapwcgard password=*********** entries=20 ignorecase=n
Was run on the original database host.
File was then copied to "F:\oracle\product\11.2.0\dbhome_1\database" on the receiving database's host it was then renamed to PWDcgard.ora as there was file there already with that name.
It did not help(same error).
The book I am using mentions the 'PASSWORD FILE' param to be used with the duplicate command but I cant find a example on how to use it so any help with that would be great.
Thanks for the effort so far guys its really appreciated. -
A little bit of help with Bind variables please
Hi,
I am having a bit of trouble with bind variables I have been looking at the Dev guide and the forum to try and achieve this and it is still not happening for me, could anybody please help or point me in the right direction:
I have created a simple PersonVO with the basic query:
Select distinct full_name from xxml_people where person_id = :1
In the PersonVOImpl.java I have added the method:
public void initQuery(String personId)
Number person = null;
try
person = new Number(personId);
catch
(Exception e){}
setWhereClauseParam(1,person);
executeQuery();
Then in the PersonAM I have added the method:
public void initPersonQuery(String personId)
getPersonVO1().initQuery(personId);
I then call this method in my processRequest section of my page controller:
PersonAMImpl am = (PersonAMImpl) pageContext.getRootApplicationModule();
String personId = "581";
am.initPersonQuery(personId);
When I try and run this I get the error:
oracle.apps.fnd.framework.OAException: oracle.jbo.SQLStmtException: JBO-27122: SQL error during statement preparation. Statement: SELECT distinct full_name from xxml_absence_calendar where person_id = :1
java.sql.SQLException: ORA-01006: bind variable does not exist
Am I binding the variables correctly? Or am I making some stupid mistake?
I am ultimately looking to create a messageChoice where the logged in user will see a list of all organisations underneath him and the one level above. I plan to do this by passing the User’s Organisation name into a VO query using the organisation as a Bind Variable. I think once I have worked out how to bind variables this should be straight forward.
Many ThanksEven though the parameter binding values may be same, you should never use the positional param more than once. So always go for the format
select distinct full_name from xxml_people where supervisor_id = :1
UNION
select distinct full_name from xxml_people where person_id = :2

Little bit of help[ with a button.
Good day all!
I need help making a button. This is what I want to happen.
I have a bunch of text, One of the words "merino" is bule as
to say there is a link hear! And I want an image of the "merino" to
come up, like a "ALT" box. Or have an image in the "ALT" box?
I know how to do this in "Flash" i.e just drop in the image
on the over state of the button event. Easy as pie! This is why I
cant get to grips with Dreamweaver! I hate it!
But I am willing to learn and maybe in time love???

HTML is a lot different from Flash! :-)
I believe you could do this using DW's Show-Hide layer
behavior - have
mousing over the link trigger a layer with the image to
appear. Someone else
may have a better idea.
Just FYI, having to mouse over a link in order to get more
information about
it isn't usually appreciated by users. You *might* want to
re-think this
plan..

Hey guys, I'm a beginner programmer and I'm having a bit of a tough time with arrays. I could really use some help!
What I'm trying to do is roll one die and then record the rolls.
Here is my sample I/O:
How many times should I roll a die?
-> 8
rolling 8 times
2, 1, 5, 6, 2, 3, 6, 5
number of 1's: 1
number of 2's: 2
and so on....
Here is my incomplete code at this moment:
//CountDieFaces.java
import java.util.Scanner;
import java.io.*;
import library.Gamble;
public class CountDieFaces
//prompt for and read in: number of times user wants to roll one die
//simulate rolling a die that many times, counting how many times each face 1 thru 6 comes up
//print out: each roll
//AND the total number of times each face occured and the percentage of the time each face occured.
Scanner scan = new Scanner(System.in);
int[] faceCount= {0,0,0,0,0,0,0};
int dice;
System.out.println("How many times would you like to roll the die?");
int dieCount = scan.nextInt();
int dieRoll = Gamble.rollDie(); // Main calling class method
int count = 1;
while(count < dieCount)
System.out.println(faceCount[count]);
count++;
}Here is the gamble library:
//Gamble.java
package library;
public class Gamble
// returns 1, 2, 3, 4, 5, or 6
public static int rollDie()
int dieRoll = (int)(Math.random()*6)+1;
return dieRoll;
}and here are the errors I have so far:
----jGRASP exec: javac -g CountDieFaces.java
CountDieFaces.java:19: <identifier> expected
System.out.println("How many times would you like to roll the die?");
^

I'm really confused with how a the gamble library gets put into the array, so any help is appreciated! Also if anyone could explain the errors to me, I would really appreciate it.
thanks in advance,
wootens

Need a bit of help with css and fullscreen
I am currently doing a javaFX application for my university project, I have it everything nearly finished, but need to finish the css component to make the application "prettier" (I am not very good on graphic design to be honest). So if i could get a bit of help on this little issue I'd be very grateful.
is there any way to make fullscreen (and if possible resizing window) to instead rearranging everything to actually do a fullscreen (like the games) and everything "grows accordingly (even though in games what it usually does is to change the screen resolution, is that possible to reproduce with javaFX?) also how to remove the message and the effect on click the "esc" key to exit the fullscreen mode?
i know that removing the focus effect on an element is with the following (if a button)
.button:focused{
-fx-background-insets: 0;
}but,is there any way to remove the effect on anything focused (TextField, Combo Box, ...)? (tried with a .textfield:focused but it did not work)
also i wanted to produce the focused effect by this way but it didn't work, how should i do it? (in fact even if i try to put this line on the button:focused, the focused effect gets removed from there, because of the insets line)
#highlight{
-fx-background-insets: 2;
-fx-background-color: yellow;
public class controller extends StackPane implements Initializable{
public void highlight(){
this.getStyleClass().add("highlight");
and last thing (for the moment) the .button seems to work for all the buttons, but trying another thing like .gridpane or .textfield or .scrollpane does not seem to work, is there any way to make it work or i should add "id" to all the elements and use the # instead?i wrote all them in the same thread becsause there were a total of 4 (and could had been more) separated by ----
should i leave it how it is or open now 4 threads for each question? -
hi,
i need some help with this piece of code. wat would it output to the screen?
int [] theArray = { 1,2,3,4,5};
for (int i = 1; i < 5; i++)
System.out.print(theArray * i + "; ");
would it output 1 * 1;
2 * 2;...
thanx
devinOk...
1] Your index into the array is off by 1 - remember that array indexing starts from 0.
2] You cannot multiply an array object. The contents? fine , go ahead but NOT the array
so your output should be something like:
operator * cannot be applied to int[] :d
try
int[] theArray = {0,1,2,3,4,5};
for(int i = 1;i<6;i++)
System.out.print(theArray*i+";");
giving you an output of 1;4;9;16;n...
if you were looking for the output stated change
System.out.print(theArray*i+";");
to
System.out.print(theArray[i]+"*"+i+";");done... -
Need Help with Array.sort and compare
Hi
I have a big problem, i try to make a java class, where i can open a file and add new words, and to sort them in a right order
Ok everthing works fine, but i get a problem with lower and upper cases.
So i need a comparator, i tried everything but i just dont understand it.
How do i use this with Array.sort??
I hope someone can help meOkay, you want to ignore case when sorting.
There are two possibilities: Truly ignore case, so that any of the following are possible, and which one you'll actually get is undefined, and may vary depending on, say, which order the words are entered in the first place:
English english German german
english English german German
English english german German
english English German german
The second possibility is that you do consider case, but it's of lower priority--it's only considered if the letters are the same. This allows only the first two orderings above.
Either way, you need to write a comparator, and call an Arrays.sort method that takes both array and Comparator.
The first situation is simpler. Just get an all upper or lower case copy of the strings, and then compare thosepublic int compare(Object o1, Object o2) {
String s1 = ((String)o1).toUpper();
String s2 = ((String)o1).toUpper();
return s1.compareTo(s2);
} You'll need to add your own null check if you need one.
For the second way, your comparator will need to iterate over each pair of characters. If the characters are equal, ignoring case, then you compare them based on case. You pick whether upper is greater or less than lower.
Of course, the need to do this assumes that such a method doesn't alrady exist. I don't know of one, but I haven't looked. -
I really need some help with the following two methods:
- A method fillArray() that accepts an integer array as a parameter and fills the array with random integers. I am encouraged to use Math.random()
- A method printArray() that accepts an integer array as a parameter and outputs every element of the array to the standard output device. I am encouraged to use print instead of println in order to save paper.
Thanks so much for your help.public class Test {
public static void main (String[] args){
int[] intArray = new int[20];
fillArray(intArray);
printArray(intArray);

hi, ive just started a java course about a month ago and am having trouble with an assignment (big trouble), basicly I was wondering if someone could help me in this program I am reading from a text file and trying to store the info in a 2d array the text file has 60 lines like this :
1 Y1 -9.30 5.65 -5.02
and my code is:
public static String [][] readfile (String fileName)

FileReader reader = new FileReader("Data_Set_1.txt");
/*file name to be filled in above*/
BufferedReader in = new BufferedReader(reader);
boolean done = false;
while(!done)
inputLine = in.readLine();
/*readline() will return null and exit this loop at the end of a line*/
if (inputLine == null)
done = true;
break;
/*break the string up declare tokeniser and pass it the inputLine string*/

}/*end try*/I left out the catch loop as it not relevant. I know that the line:
data[genes][col] = line[genes], line[col];
is wrong but I dont know how to fix it and cant find the answer anywhere, if anyone can spot any other mistakes it would be great to let me know and im sorry if Ive posted wrong or anything like that ill fix it next time, any help or comments would be much appreciated.
ThanksNo need to apologise for being new to Java. After all, that is what the forum is for! If you wanted to apologise about your nickname well.... it'll do. :-)
Your thinking is right. However do give gimbal2's idea a little thought. I do not know what each row is storing but if the data for each row were in an object, then the object could use meaningful names and provide sensible formatting and so on. However I have not seen the details of the assignment that your teacher gave you so it may have to be arrays. But what you would have would be an array of object called LineData or Genes. You might cycle through the array asking each object to call out its name and a feature for example.
In general you gain very little advantage by passing a "temp" array to another array "line" using an equals sign. The reason is that there is only one array it just has two names! A bit like pinning an extra registration plate on a car! If you really wanted two arrays you would have to investigate "cloning" of arrays. However if you add the temp array (or whatever you call it) to another array such as your two dimensional array, then you can re-use the temp name by applying "=new" to create a new array. This will not affect the existing "array within an array" because it no longer needs a name - it is located by a number now!!!
Array[] is fast in Java but you have to give it a size before you can use it. Arraylist is less fast but has the ability to grow. Not that the speed difference will be at all noticeable. Actually the internal working of the Arraylist uses arrays and cloning and such like.
thesonofdad has given some good code. Again I might consider putting it in gimbal2's object though.
I have covered quite a lot of ground so feel free to ask questions. -
I'm trying to create a flash program that uses it's own code to send and create images. Each square has a colour and that colour gets added into the array. A black, then grey, then white is:
filecode = ["Bl", "Gr", "Wh"];
That works fine, but when I try to paste it into an Input text box it will only fill in the first part of the array.
filecode = ["Bl,Gr,Wh"];
So the program has NO idea what I want.
The only ways I can think of fixing this is by putting in 402 text boxes to suit every box...But every one of them needs a Variable Name.
Or by sending the information straight into the array. But this way you are just looking at what you just drew, and that is not at ALL practical.
Helping me with this headache will be greatly apprectiated.
FlashDrive100.If you can explain the first part of your posting it might become a little clearer what you are trying to do and what isn't working... particularly this...
" when I try to paste it into an Input text box it will only fill in the first part of the array."
I can't speak for anyone else, but at this point, I share your file's problem... not knowing what you want. -
Need a bit of help with a code
Hello adobe community!
i have been fiddling around with FLASH MX and have been making a game VERY slowly.
i've picked up alot since starting and have restarted making said game MANY MANY times =D...
But i have now got a copy that is neat and clean and works really well BUT i've come into a bit of a problem.
i have _global.goldenticket = 0; on my first frame along with other variables and i have made a single location where one can aquire a "goldenticket".
now things are starting to confuse me... ive added a button inside a movie clip which if clicked "should" check if i have a golden ticket and then allow me to jump to the frame specified...
on(release){
if(goldenticket=="1"){
money -= 50;
energy -=50;
_root.gotoAndPlay("enter");
}else{
this.enabled=false;
however the button doesnt seem to see my ticket (even tho ive added a dynamic textbox to keep track of how many i have, which is 1)
ive tried many different ways to go around this but i cannot seem to get it to work...
please someone help me... in relativly simple answers please =\ im only a few days into flash learning and codeing. but im enjoying what im doing so im learning quickly.
will have my face to the screen in waiting =D
Thank you to everyone who took a look at my thread!THANK YOU!!!
REALLY quick response WITH lang i could easily understand...
mate thank you haha been wrapping my brain for hours on end with other things didnt even occure to me to slap _global infront. -

But I cant do this for 200 elements. Are the loops nested right?
