No, I don't understand what you mean, even after looking at your code.
There is an array labeled "want". Which of the outputs do you want to look like that and how does it relate to the current default input?

i'm trying to design a linear interpolator as cleanly and performant as possible in pl/sql & sql
imagine i have a trade table
id
and a trade_profile table
id
profile_point
value
which i expect for every trade to contain the profile_points 1, 2, 3, 4 & 5, however that's not always the case.
i can't decide whether i should trawl trade by trade using bulk collect, inspecting each profile point to confirm it exists, and if not,
find the points to left and right and interpolate
or
define an uber sql query, possibly with analytic functions that give me all the inserts.
any thoughts would be appreciated.Typically the solution, if done purely in SQL performs better then the PL/SQL equivalent.
If you can provide the information below you'll most likely get the solution, if not a good starting point.
1. Oracle version (SELECT * FROM V$VERSION)
2. Sample data in the form of CREATE / INSERT statements.
3. Expected output
4. Explanation of expected output (A.K.A. "business logic")
5. Use \ tags for #2 and #3. See FAQ (Link on top right side) for details. -
How To... Get linear Interpolation between Position keyframes ???
Hi....
cannot get my head around this one...
When I do i..e opacity keyframes I can open video animation and add interpolation attributes like bezier & linear to the keyframes...
However, for i.e. position and all other keyframe-attributes I cannot. And the promblem is that FCPx adds (automatically) a logarithmic start and end... So say I want to move a steady-shot from left to right over 2 seconds' worth of time, I'll set a keyframe to the beg. of the clips then go to the end od the clip and add another KF and then move the clip over by i.e. 20 pixels. The problem is that the movement (interpolation) is NOT linear but logarithmic... Which ***** for what I am doing...
I have tried right-clicking ANYTHING but I have NO control over the KF properties...
Any ideas ?thanks for chiming in ;-)
I know that I can create a motion effect that will handle this problem. And then load up that template in fcpx. As a matter of fact I have already built one since writing this message ;-)
However, I thought that I HAD to be missing something VERY obvious since an app carrying the name PRO should be providing its user with the capability of the MOST basic stuff. Which is does -- but only for opacity keyframes...
This app (in good and BAD) never seizes to amaze me.
Clearly Mr. Ubilos is NOT an editor that is using keyframes much ;-) -
Linear search between two arrays
I'm having trouble with the comparison of an array of football teams and an array of team names that may or may not be in the football team array. I have read both .txt files into their own arrays and parsed the team array with substring in order to isolate the team name. I know I can read both the search array and the team names individually because I tested it with a println. I think my problem is in the comparison "if" statement.
public void seqSearch()//Sequential(linear) search
int j=0, s;
//int m = j+1;
for(s=0; s<searchSize; s++)//increments through the search array
for(j=0; j<teamArray.length; j++)//increments through the team array
if(teamArray[j].getName().equals(search[s]))//I think this is where the problem is
System.out.println("Found " + teamArray[j].getName() + "after" + j + "searches.");
break;
else
System.out.println(teamArray[j].getName());//prints through all of the names during each search for testing
if(j == teamArray.length-1)
System.out.println("Can't find " + search[s] + " after " + j + " searches");
}//end for
}//end seqSearch()My output prints the names of each team on their own line and at the end it always says that it can't find each search term.
Ex.
Bears
Bengals
Bills
Vikings
Can't find Bills after 32 searches
Bears
Bengals
Bills
Vikings
Can't find Eagles after 32 searches
etc
I though that .equals was the way to compare in this situation. Any idea what I'm doing wrong?Dave,
teamArray[j].getName().equals(search[s]))what is the implementation class which is returned from "search[s]" and from "eamArray[j].getName()"
if both of them are java.lang.String then us "equalsIgnoreCase" instead of "equals"
if the implementation class is different, then you have to override the equal method and implement your own.

I'm trying to create two different hash tables, and put the hased data into each one using linear probing. I'm using an array, but I'm having a little problem (mainly with the circular array part, I think). I've posted what I've got below. Every time I try to test it, I get a NullPointerException. I know the code is a little (a lot) sloppy, but I just sat down and wrote it right now, so take it easy :P
import java.util.Scanner;
import java.io.*;
public class HashingTable {
private static HashObject[] array1;
private static HashObject[] array2;
private static int collision1, collision2;
public HashingTable() {
HashObject[] array1 = new HashObject[145];
HashObject[] array2 = new HashObject[415];
collision1 = collision2 = 0;
public static void fillHashTable(String fileName) throws IOException {
Scanner scan = new Scanner(new File(fileName));
while(scan.hasNext()) {
HashObject hashObject1, hashObject2;
String word = scan.next().toUpperCase();
int total = 0;
for(int i=0; i < word.length(); i++) {
char c = word.charAt(i);
if(Character.isLetterOrDigit(c))
total += (int)c;
if(c == '-')
total += (int)c;
if(c == '/')
total += (int)c;
int hashedInt_1 = total%135;
hashObject1 = new HashObject(word, hashedInt_1);
int hashedInt_2 = total%401;
hashObject2 = new HashObject(word, hashedInt_2);
for(int j=0; j < array1.length; j++) {
if(j == hashedInt_1)
if(array1[j] == null)
array1[j] = hashObject1;
else
while(array1[j] != null) {
j++;
collision1++;
if(j+1 > array1.length)
j = 0;
for(int k=0; k < array2.length; k++) {
if(k == hashedInt_2)
if(array2[k] == null)
array2[k] = hashObject2;
else
while(array2[k] != null) {
k++;
collision2++;
if(k+1 > array2.length)
k = 0;
private static class HashObject {
protected String hashedWord;
protected int hashedValue;
public HashObject(){}
public HashObject(String s, int n) {
hashedWord = s;
hashedValue = n;
}Also, it made me mark my instance variables as static, why is that?Wait a minute... I just realized that several things are awkward in your code. For example, why do you loop until you find k to be equal to the other number? Here is a revision:
if(array1[hashedInt_1] == null)
array1[hashedInt_1] = hashObject1;
else
for(int j = 0; the thing doesn't equal null; j++) {
collision1++;
if(j+1 == array1.length)
j = -1;
//check if the array1[j] is null. If it is, then change it and break the loop
}I think the error in the circle is that you have 2 loops for no reason, and the inner loop is not doing anything - it's value doesn't reset.

Problem in array output, pls help!
i made an array:
public class Estudyante
String studentNo;
String studentName;
String address;
String phone;
String email;
public void displayDetails()
System.out.println(studentNo);
System.out.println(studentName);
System.out.println(address);
System.out.println(phone);
System.out.println(email);
public class StudentFinder
//define the variables of the class
Estudyante estObjects[];
//initialize the variables
public StudentFinder()
//creating an array of 3 estudyantes
estObjects = new Estudyante[3];
//creating objects of all the three elements in an array
for(int ctr = 0; ctr !=estObjects.length;ctr++)
estObjects[ctr] = new Estudyante();
//assigning test values
//estudyante 1 details
estObjects[0].studentNo = "0001";
estObjects[0].studentName = "Rez";
estObjects[0].address = "Pasig";
estObjects[0].phone = "111-1111";
estObjects[0].email = "[email protected]";
//estudyante 2 details
estObjects[1].studentNo = "0002";
estObjects[1].studentName = "Reza";
estObjects[1].address = "Manila";
estObjects[1].phone = "222-2222";
estObjects[1].email = "[email protected]";
//estudyante 3 details
estObjects[2].studentNo = "0003";
estObjects[2].studentName = "Reza Ric";
estObjects[2].address = "Malate";
estObjects[2].phone = "333-3333";
estObjects[2].email = "[email protected]";
//declare the method of the class
public void displayFinder()
//add the code for displaying estudyante details
for (int ctr = 0;ctr != estObjects.length;ctr++)
estObjects[ctr].displayDetails();
//the displayDetails() method is present in the Estudyante class
//code the main() method
public static void main(String args[])
StudentFinder finderObject;
finderObject = new StudentFinder();
finderObject.displayFinder();
problem:
when i run this in command prompt, it displays all the 3 sets of details
question:
how will i display the set of details i want and not all of them?
eg: i only want the details of studentNo = "0001"
so in command prompt i execute
java StudentFinder 0001
how will i be able to get the details for studentNo = "0001" only and how will i display "No such student" if the studentNo asked for is not in any of the details.Hi KikiMon,
In your displayFinder() method you'll have to take an argument, specifying which Student to display. Like this:
public void displayFinder(String target)
for (int ctr = 0;ctr != estObjects.length;ctr++)
if(estObjects[ctr].studentNo.equals(target)) {
estObjects[ctr].displayDetails();
An in your main you'll have to forward a commandline argument like this:
public static void main(String args[])
StudentFinder finderObject;
finderObject = new StudentFinder();
finderObject.displayFinder(args[0]);

I am facing a problem with the array of JCheckBox. Without array it works but when I use array it gives NullPointerException. No compile time error. I am using Null Layout. But I need to use the array. How can I solve this?
Here is the code.
JCheckBox jCheckBox_Questions[] = new JCheckBox[3];
JCheckBox box = new JCheckBox();
Dimension d[] = new Dimension[3] ;
String strQuestions[] = {"No Child ?","Jaundice ?","Migraine ?"};
int j=20,k=150;
// This works
box.setText(strQuestions[0]);
add(box);
d[1]= box.getPreferredSize();
box.setBounds(j,k,d[1].width,d[1].height);
k=k+20;
//When I add the follwing fragment it gives NullPointerException
jCheckBox_Questions[0]. setText(strQuestions[1]);// in this line
add(jCheckBox_Questions[0]);
d[2]= jCheckBox_Questions[0].getPreferredSize();
jCheckBox_Questions[0].setBounds(j,k,d[2].width,d[2].height);Hi,
classic error: in fact the code
JCheckBox jCheckBox_Questions[] = new JCheckBox[3]; doesn't instantiate the checkboxes, it's only allocating 3 memory pointers (inited to null), ready to receive the futures instances of checkboxes. So you should have typed:
JCheckBox jCheckBox_Questions[] = new JCheckBox[3];
// Here we create the 3 objects
for (int i=0;i<3;i++) jCheckBox_Questions[ i ] = new JCheckBox();
//...Hope this will help,

A basic question/problem with array element as undefined
Hello everybody,
thank you for looking at my problem. I'm very new to scripting and javaScript and I've encountered a strange problem. I'm always trying to solve all my problem myself, with documentation (it help to learn) or in the last instance with help of google. But in this case I am stuck. I'm sure its something very simple and elementary.
Here I have a code which simply loads a text file (txt), loads the content of the file in to a "var content". This text file contents a font family name, each name on a separate line, like:
Albertus
Antenna
Antique
Arial
Arimo
Avant
Barber1
Barber2
Barber3
Barber4
Birch
Blackoak ...etc
Now, I loop trough the content variable, extract each letter and add it to the "fontList[i]" array. If the character is a line break the fontList[i] array adds another element (i = i + 1); That's how I separate every single name into its own array element;
The problem which I am having is, when I loop trough the fontList array and $.writeln(fontList[i]) the result in the console is:
undefinedAlbertus
undefinedAntenna
undefinedAntique
undefinedArial ...etc.
I seriously don't get it, where the undefined is coming from? As far as I have tested each digit being added into the array element, I can't see anything out of ordinary.
Here is my code:
#target illustrator
var doc = app.documents.add();
//open file
var myFile = new File ("c:/ScriptFiles/installedFonts-Families.txt");
var openFile = myFile.open("r");
//check if open
if(openFile == true){
$.writeln("The file has loaded")}
else {$.writeln("The file did not load, check the name or the path");}
//load the file content into a variable
var content = myFile.read();
myFile.close();
var ch;
var x = 0;
var fontList = [];
for (var i = 0; i < content.length; i++) {
ch = content.charAt (i);
if((ch) !== (String.fromCharCode(10))) {
fontList[x] += ch;
else {
x ++;
for ( i = 0; i < fontList.length; i++) {
$.writeln(fontList[i]);
doc.close (SaveOptions.DONOTSAVECHANGES);
Thank you for any help or explanation. If you have any advice on how to improve my practices or any hint, please feel free to say. Thank youCarlosCantos wrote an amazing script a while back (2013) that may help you in your endeavor. Below is his code, I had nothing to do with this other then give him praise and I hope it doesn't offend him since it was pasted on the forums here.
This has helped me do something similar to what your doing.

Problems binding array in C# to stored procedure.
I'm having trouble trying to pass an array of ID's to a stored procedure that is expecting an array (listed the procedure definition below). My current interface doesn't return an error, but it also doesn't insert the proper id's.

This ran fine, and created four rows in the table, but the source id's were (1, 2, 3, 4) instead of (1, 172, 412, 7953) which were the ones I passed in.
Does anyone know what I'm doing wrong here?
Thanks,
GaurangaHi,
I think you have a problem in you PL/SQL procedure. When you receive an array in the procedure, it is your responsibility to parse it explicitely with a loop or to bulk insert with a "forall" (implicit).
For instance, here is an example of a procedure of mine. I don't catch exceptions as I want the C# calling code to know about them:
The type t_* are defined like yours.
procedure UpdateDistribDates(p_bannerid in t_bannerid,
p_promonumber in t_promonumber,
p_datenumber in t_datenumber,
p_actualdate in t_actualdate ) is
BEGIN
-- First delete the existing dates in bulk
FORALL I IN P_BANNERID.FIRST..P_BANNERID.LAST
DELETE FROM PROMODISTRIBDATE
WHERE BANNERID = P_BANNERID(I)
AND PROMONUMBER = P_PROMONUMBER(I);
-- Then, insert the values passed in arrays.
FORALL I IN P_BANNERID.FIRST..P_BANNERID.LAST
INSERT INTO PROMODISTRIBDATE
(BANNERID,
PROMONUMBER,
DATENUMBER,
ACTUALDATE)
VALUES (P_BANNERID(I),
P_PROMONUMBER(I),
P_DATENUMBER(I),
P_ACTUALDATE(I));
END;
As you can see, the FORALL keyword will process the arrays passed as any other PL/SQL array in one chunk.
When you do the insert like:
INSERT INTO wweb.dm_associations
(dm_association_id
,dm_message_id
,association_type
,source_id
,source_column_name
,active_flag
,create_date
,create_user
,last_update_date
,last_update_user)
VALUES
(wweb.dm_associations_s.NEXTVAL
,p_dm_message_id
,p_association_type
,v_source_id
,v_source_column_name
,1
,SYSDATE
,p_create_user
,SYSDATE
,p_create_user);
In source_id, you insert the index of the table, not the value of the field.
I would suggest you completely rewrite this procedure by using the explicit loop like this:
1/ Explicit loop
FOR i IN 1 .. p_sources.COUNT LOOP
-- Check the existence
EXIST_FLAG := 0;
BEGIN
SELECT 1
INTO EXIST_FLAG
FROM ...
WHERE ...
AND a.source_id = p_source(i) <-- You are parsing here
AND ...
EXCEPTION
WHEN OTHERS THEN -- Nothing was found
EXIST_FLAG := 0;
END;
IF (EXIST_FLAG = 1)
INSERT INTO wweb.dm_associations
(dm_association_id
,dm_message_id
,association_type
,source_id
,source_column_name
,active_flag
,create_date
,create_user
,last_update_date
,last_update_user)
VALUES
(wweb.dm_associations_s.NEXTVAL
,p_dm_message_id
,p_association_type
,p_source(i) <-- You parse here
END IF;
END LOOP;
2/ Implicit loop and bulk insert
You would need to completely review the logic and build an array that maps exactly the row of the table you are trying to insert into. Parse the array and check for the existence of your entry, delete the row in memory when not found, then, after the loop do a bulk insert with a "forall".
Hope it helps,

URGENT: Problem sending array of complex type data to webservice.
Hi,
I am writing an application in WebDynpo which needs to call External web service. This service has many complex data types. The function which I am trying to access needs some Complex data type array. When i checked the SOAP request i found that the namespace for the array type is getting blank values. Because of which SOAP response is giving exception.
The SOAP request is as below. For the <maker> which is an array ,the xmlns:tns='' is generated.

Another problem:
If the webservice is having overloaded methods , it is generating error for the second overloaded method.The stub file itself contains statment as follow:

can anyone guide me on this?
Thanks,
Mital.I am having this issue as well.
From:
http://help.sap.com/saphelp_nw04/helpdata/en/43/ce993b45cb0a85e10000000a1553f6/frameset.htm
I see that:
The WSDL document in rpc-style format must also not use any soapenc:Array types; these are often used in SOAP code in documents with this format. soapenc:Array uses the tag <xsd:any>, which the Integration Builder editors or proxy generation either ignore or do not support.
You can replace soapenc:Array types with an equivalent <sequence>; see the WS-I example under http://www.ws-i.org/Profiles/BasicProfile-1.0-2004-04-16.html#refinement16556272.
They give an example of what to use instead.
Of course I have been given a WSDL that has a message I need to map to that uses the enc:Array.
Has anyone else had this issue? I need to map to a SOAP message to send to an external party. I don't know what they are willing to change to support what I can do. I changed the WSDL to use a sequence as below just to pull it in for now.
Thanks,

Output problem in array, code included.
Been hacking away at a starting java class for a few months now, and never had to resort to asking you guys for help.
However, i missed class all week due to work conflicts, so i couldn't question my professor on this problem. Oddly, the actual array bits i'm fine with, but the output has me stalled.
The program is ment to square the numbers 1-10, and then it wants me to output the square and the original number on the same line (It also wanted me to use Math.pow to get the squares, but that gave me a whole slew of syntax errors i couldn't figure out, so i did it the easy way).
I'm not sure how to do this, have tried quite a few things, but i'm fairly certain i'm just missing something obvious, any tips would be helpful.
import javax.swing.*;
public class J6E1 {
public static void main( String args[] )
int [] Data = new int [11];
for (int x=1; x<Data.length; x++)
Data[x] = (x*x);
for (int x=1; x<Data.length;x++)
System.out.println(Data[x] );
System.exit(0);
}So for a given x, you have stored x*x value in Data[x].
What about printing both x and Data[x] then? -
Another question about problem using arrays
Hey guys, if you helped me answer my other problems thanks a bunch and again thank you to all the people who try to help us learn the unique language of Java. Anyway the other problem goes like this:
Return the number of even ints in the given array. Note: the % "mod" operator computes the remainder, e.g. 5 % 2 is 1.
countEvens({2, 1, 2, 3, 4}) ?? 3
countEvens({2, 2, 2}) ?? 3
countEvens({1, 3, 5}) ?? 0
Ok so basically I would want to count all the evens in an array and basically if I use the module operator I can figure out whether something is even or not if it returns me a 0. So I know there will be an if statement there. I'm wondering if I would have to also use a "for each" statement to check every element. I would also need a variable to keep count of the number of elements that are even. Any suggestions on how the implementation of this method should be like?Hey thanks a bunch actually, I just pretty much reasoned it out and ended up with this:
public int countEvens(int[] nums) {
int count = 0;
for (int e:nums)
if ((e%2)==0)
count++;
return count;
}Really appreciate the help. -
Question about problem using arrays...
Hey guys, thanks a bunch for the help - I always really appreciate how you guys can take the time to help us people still learning about this amazing language. Anyway the problem goes like this:
Given an int array, return a new array with double the length where its last element is the same as the original array, and all the other elements are 0. The original array will be length 1 or more. Note: by default, a new int array contains all 0's.
makeLast({4, 5, 6}) ?? {0, 0, 0, 0, 0, 6}
makeLast({1, 2}) ?? {0, 0, 0, 2}
makeLast({3}) ?? {0, 3}//this is basically what it's supposed to do
public int[] makeLast (int[] nums)
So I'm just wonder on how the implementation would be like. I know that I would first want to double the array length. After that, I would want to replace every element of the original array with 0's but keep the last element the same. Any suggestions guys?So I'm just wonder on how the implementation would be like. I know that I would first want to double the array length.Well, you can't double the length per se. You can't dynamically change the size of an array. Rather, you'll need to create a new array with the size as specified by the homework assignment.
After that, I would want to replace every element of the original array with 0's but keep the last element the same.Since it's a new array, you wouldn't actually replace anything.
Any suggestions guys?Hint: the default value, in an array of numbers, is zero. -
Hi guys am having difficulty to access an array from another method in the came class
import java.io.*;
class arr
int i,j,k;
int r;
int arr1[][] = new int [30][30];
void input() throws IOException
InputStreamReader ir= new InputStreamReader(System.in);
BufferedReader br = new BufferedReader(ir);
String s= br.readLine();
int r = Integer.parseInt(s);
System.out.println("Value of r is:"+r);
for(i=0;i<r;i++)
for(j=0;j<5;j++)
arr1[i][j]=k;
k++;
void display()
System.out.println("r is"+r); // When executed r = o
for(i=0;i<r;i++)
for(j=0;j<5;j++)
System.out.println(arr1[i][j]);
class testing
public static void main(String args[]) throws IOException
arr a = new arr();
a.input();
a.display();
}How come that r =0 when i input another value?
Please guys how can i overcome this problem??
thanksOk TIM ill see for the variables i and j
For the array of size 30x30 ,i have already done what u said but had problems to access it in the display() so ive done it that way ..Guys i' having problems in the do....while loop (main ())
normally when i input "Y" i should be promped to the menu but the programs ends....
