Need help with an array function

I'm using the array index function and i would like to be able to control what elements go out on it. For example, if i wanted only the first element to go out, i don't want the second element to send out zero. Is there any way i can control what elements leave the array index function. I also don't understand what the index inputs do on that function either. If anyone has any advice on the application or can modify it in any way, please help.

The index inputs determine what elements are retrieved. For example of you would wire a 10 and a 20 to your two index inputs, you would bet element #10 and element #20 of your array. You can resize it to get any desired number of elements.
If you don't wire the index inputs, you'll get the first two elements.
If you only wire the top index input (e.g a 10), you'll get element #10 and #11.

I need help with 2 arrays

I need help with this portion of my program, it's supposed to loop through the array and pull out the highest inputted score, currently it's only outputting what is in studentScoreTF[0].
private class HighScoreButtonHandler implements ActionListener
           public void actionPerformed(ActionEvent e)
          double highScore = 0;
          int endScore = 0;
          double finalScore = 0;
          String tempHigh;
          String tempScore;
          for(int score = 0; score < studentScoreTF.length; score++)
          tempHigh = studentScoreTF[score].getText();
                tempScore = studentScoreTF[endScore].getText();
          if(tempHigh.length() < tempScore.length())
               highScore++;
               finalScore = Double.parseDouble(tempScore);
         JOptionPane.showMessageDialog(null, "Highest Class Score is: " + finalScore);This is another part of the program, it's supposed to loop through the student names array and pull out the the names of the students with the highest score, again it's only outputting what's in studentName[0].
     private class StudentsButtonHandler implements ActionListener
           public void actionPerformed(ActionEvent e)
          int a = 0;
          int b = 0;
          int c = 0;
          double fini = 0;
          String name;
          String score;
          String finale;
          String finalName = new String();
          name = studentNameTF[a].getText();
          score = studentScoreTF.getText();
          finale = studentScoreTF[c].getText();
          if(score.length() < finale.length())
               fini++;
               name = finalName + finale;
     JOptionPane.showMessageDialog(null, "Student(s) with the highest score: " + name);
               } Any help would be appreciated, this is getting frustrating and I'm starting to get a headache from it, lol.

Heres a working example:
class Compare {
    public int getHighest(int[] set) {
        int high = set[0];
        for(int i = 0; i < set.length; i++) {
            if(set[i] > high) {
                high = set;
return high;

Hello guys need help with reverse array

Need help reversing an array, i think my code is correct but it still does not work, so im thinking it might be something else i do not see.
so far the input for the array is
6, 25 , 10 , 5
and output is still the same
6 , 25 , 10 , 5
not sure what is going on.
public class Purse
    // max possible # of coins in a purse

        contents[count] = coinType;

       for (int i = contents.length - 1; i >=0 ; i--)                        // 4, 3 , 2, 1, 0
            countA++;                                             // count = 5
        while ( x < y)
            int temp = contents[x];
            contents[x] = contents [y];
            contents [y] = temp;
            y = y- 1;                                         // 4 , 3 , 2, 1 , 0
            x = x + 1 ;                                             // 0 , 1, 2 , 3 , 4
}

ok so i went ahead and followed what you said
public void reverse()
      int a = 0;
      int b = contents.length - 1;
      while (b > a)
          int temp = contents[a];
          contents[a] = contents;
contents [b] = temp;
a++;
b--;
}and its outputting { 0, 0, 0, 0}
im thinking this is because the main array is has 10 elements with only 4 in use so this is a partial array.
Example
the array is { 6, 25, 10, 5, 0, 0, 0, 0, 0, 0,}
after the swap
{0, 0 , 0 , 0, 0 , 0 , 5 , 10 , 25, 6}
i need it to be just
{ 5, 10, 25, 6}
so it is swapping the begining and end but only with zeroes the thing is i need to reverse the array without the zeroes

Need Help with simple array program!

Hi, I have just recently started how to use arrays[] in Java and I'm a bit confused and need help designing a program.
What this program does, it reads in a range of letters specified by the user. The user then enters the letters (a, b or c) and stores these characters into an array, which the array's length is equal to the input range the user would enter at the start of the program. The program is then meant to find how many times (a,b and c) appears in the array and the Index it first appears at, then prints these results.
Here is my Code for the program, hopefully this would make sense of what my program is suppose to do.

}     Some errors i get with my program are:
When reading in the letters to store into the array, I get the last letter I entered placed into the entire array. Also I believe my code to find the Index is incorrect.
Example Testing: How many letters would you like to read? 3
Enter letter (a, b or c) (# to quit): a
Enter letter (a, b or c) (# to quit): b
Enter letter (a, b or c) (# to quit): c
It prints "There are no a's'" (there should be 1 a at index 0)
"There are no b's" (there should be 1 b at index 1)
and "There are 3 c's, first appearing at index 0" ( there should be 1 c at index 2)
The last thing is that my code for when the user enters "#" that the input of letters would stop and the program would then continue over to the counting and searching part for the letters, my I believe is correct but I get the same problem as stated above where the program takes the character "#" and stores it into the entire array.
Example Testing:How many letters would you like to read? 3
Enter letter (a, b or c) (# to quit): a
Enter letter (a, b or c) (# to quit): #
It prints "There are no a's'" (should have been 1 a at index 0)
"There are no b's"
and "There are no c's"
Can someone please help me??? or does anyone have a program simular to this they have done and would'nt mind showing me how it works?
Thanks
lou87.

Without thinking too much...something like this
for(int start = 0; start < size; start++) {
            System.out.println("Please enter a letter (a, b or c) ("+size+" max), enter # to stop:");
            input = Keybd.in.readChar();
            while((input != 'a') && (input != 'b') && (input != 'c') && (input != '#')) {
                Screen.out.println("Invalid Input");
                System.out.println("Please enter a letter (a, b or c) ("+size+" max, enter # to stop:");
                input = Keybd.in.readChar();
            if(input == '#') {
                    break;
            letter[start] = input;
        }you dont even need to do start = size; coz with the break you go out of the for loop.

Need help with user defined function

Hello SDN,
I need some help with a user-defined function. My source message contains multiple
generic records (1000 char string), and my target message is 1 header record,
then multiple generic records. See description of source and target messages below:
Source:
GenericRecordTable 1..unbounded
    Row (1000 char string)
Target:
Field1 (char5)
Field2 (char5)
Field3 (char5)
IT_Data
    GenericRecordTable 1..unbounded
      Row (1000 char string)
Basically, what I need to do in my user defined funtion is to map the first record
in my source record to the 3 header fields, then map all of the rest of the records
(starting from line 2) into the GenericRecordTable.
Can someone please help me with the code for the user defined function(s) for this
mapping?
Thank you.

hi,
Activities
1. To create a new user-defined function, in the data-flow editor, choose Create New Function (This
graphic is explained in the accompanying text), which is located on the lower left-hand side of the
screen. In the menu, choose Simple Function or Advanced Function.
2. In the window that appears, specify the attributes of the new function:
Name
Technical name of the function. The name is displayed in the function chooser and on the data-flow
object.
Description
Description of how the function is used.
Cache
Function type (see above)
Argument Count
In this table, you specify the number of input values the function can process, and name them. All
functions are of type String.
3. In the window that appears, you can create Java source code:
a. You can import Java packages to your methods from the Imports input field, by specifying them
separated by a comma or semi-colon:
You do not need to import the packages java.lang., java.util., java.io., and java.lang.reflect. since
all message mappings require these packages and therefore import them. You should be able to
access standard JDK and J2EE packages of the SAP Web Application Server by simply specifying the
package under Import. In other words, you do not have to import it as an archive into the Integration
Repository. You can also access classes of the SAP XML Toolkit, the SAP Java Connector, and the
SAP Logging Service (see also: Runtime Environment (Java-Mappings)).
In addition to the standard packages, you can also specify Java packages that you have imported as
archives and that are located in the same, or in an underlying software component version as the
message mapping.
b. Create your Java source text in the editor window or copy source text from another editor.
4. Confirm with Save and Close.
5. User-defined functions are limited to the message mapping in which you created the function. To
save the new function, save the message mapping.
6. To test the function, use the test environment.
The new function is now visible in the User-Defined function category. When you select this category,
a corresponding button is displayed in the function chooser pushbutton bar. To edit, delete, or add the
function to the data-flow editor, choose the arrow next to the button and select from the list box
displayed.

Need help with an array

I'm working on creating an array that is basically a deck of cards, this is the problem.
I'm getting this error:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 4
void main()
    final int ARRAY_SIZE = 52;
    String[] deck = new String[ARRAY_SIZE];
    String[] cardValue = new String[]{"A","2","3","4","5","6","7","8","9","T","J","Q","K"};
    String[] cardSuit = new String[]{"C","H","D","S"};
    for (int count = 0; count < ARRAY_SIZE; count++)
      deck[count]= cardValue[count] + cardSuit[count];
    }I Know that this is because cardSuit is reaching the end of the array, but how do I keep this from happening and make it start from the beginning until i reach the end of the cardValue array?

By the way thanks for the help guys, I'm in a pinch for this assignment and I appreciate all of the help.
void main()
    final int ARRAY_SIZE = 52;
    String[] deck = new String[ARRAY_SIZE];
    String[] cardValue = new String[]{"A","2","3","4","5","6","7","8","9","T","J","Q","K"};
    String[] cardSuit = new String[]{"C","H","D","S"};
    for (int count = 0; count < ARRAY_SIZE; count++)
      deck[count]= cardValue[count % 13] + cardSuit[count % 4];
      showCards(deck);
void showCards(String [] list)
    String cards = ("card");
    for (int count = 0; count < list.length; count++)
      print (cards);
This is what I'm talking about. I need to be able to call the showCards method and have it display whatever cards are currently in the players hand regardless of how many cards there are. I believe that I'm right when I used the void declaration because I don't want it the method to return anything to itself.
Right now with the code as is, i get "card" typed out 52 times.
First how do I go about having it print out the complete deck and the order that they are in?
Is there a way to create the deck in pre-sorted like I have below?
This was the assignment:
Write a ConsoleProgram to create a deck of playing cards, shuffle them, and deal out 5 cards to the player. To do this:
� You will need an array of 52 cards. In the basic version of this program, each card is a string in the form �XY�, where X is the rank (A, 2, 3, 4, 5, 6, 7, 8, 9, T, J, Q, K, A) and Y is a letter designating the suite (C, H, D, S).
� You will need to shuffle the cards by swapping the positions of two randomly selected cards in the array. For this, you should write and use three methods:
o randRange � a method which takes 2 parameters: a minimum integer and a maximum integer. It creates a random integer in this range and returns it.
o swap � a method which takes 3 parameters: an array of cards and two subscripts. It swaps the array elements with the given subscripts and returns nothing in its name.
o shuffle � a method which takes 2 parameters: an array of cards and a number of times to swap cards. It shuffles by swapping two randomly selected cards the desired number of times (a possibly different pair each time). It returns nothing in its name (so it is a void method).
� You will need an array of 5 cards for the player�s hand. After shuffling the deck, you will fill this array with the first 5 cards from the deck.
� Display the unshuffled deck, then the shuffled deck, and finally the player�s hand. Indicate which is which in the output. For example, the output of one program run might look like this: Unshuffled: 2C, 3C, 4C, 5C, 6C, 7C, 8C, 9C, TC, JC, QC, KC, AC, 2D, 3D, 4D, 5D, 6D, 7D, 8D, 9D, TD, JD, QD, KD, AD, 2H, 3H, 4H, 5H, 6H, 7H, 8H, 9H, TH, JH, QH, KH, AH, 2S, 3S, 4S, 5S, 6S, 7S, 8S, 9S, TS, JS, QS, KS, AS Shuffled: 2C, QC, 3S, 9C, 9S, 6C, 6H, 3C, QH, 2H, 8C, 9H, AH, 4S, AS, TH, 6D, 3D, 2S, 8S, 5C, TC, 4C, 4D, 7C, AD, 9D, JD, 4H, 5S, KH, 7H, JS, 8D, TD, KC, 3H, 2D, KD, AC, KS, JC, 5H, JH, 8H, 5D, 7S, TS, QD, 7D, 6S, QS Your Hand: 2C, QC, 3S, 9C, 9S

The problem I am currently having is that I want to display variable myblock down 10 times and then test it for collison,
I am using the variable I to store the blocks, pls excuse me as I am new to this, If I manally set the variable i to lets say 1 and 2
and then test for collison it works, but when I use I from the for loop it only detects one object from the array, I think that there is something
probably simple missing such as an extra variable, as you can see from the code I am trying to use the ' i ' to replace for instance addChild(blockarray[1]);
I have set it manually to display two blocks in the code below, collison detection works, but when I want to use a loop to display and test the collison
it only picks up one of the blocks, not sure if this is because variable i is set to 0 in the for loop, any help would be greatly appreciated, this is my first post on here as I'm new to Actionscript, ty for reading8-)
var thehero:BlueBlock = new BlueBlock;
thehero.x=20;
thehero.y=20;
addChild(thehero);
var blockarray = new Array()
for(var i:Number=0;i<10; i++)
// this is where I setup my blocks
var myblock:BlueBlock = new BlueBlock;
blockarray[i]=myblock;
blockarray[i].x = Math.random()*500;
blockarray[i].y = Math.random()*400;
trace(blockarray[i]);
blockarray.push(myblock);
//addChild(blockarray[i]);
addChild(blockarray[1]);
addChild(blockarray[2]);
// Check for keyboard events such as the arrow keys been pressed
stage.addEventListener(KeyboardEvent.KEY_DOWN, myKeyDown);
stage.addEventListener(Event.ENTER_FRAME,blockcollision);
function myKeyDown (e:KeyboardEvent){
if (e.keyCode == Keyboard.LEFT){
thehero.x -=5;
if (e.keyCode == Keyboard.RIGHT){
thehero.x +=5;
if (e.keyCode == Keyboard.UP){
thehero.y -=5;
if (e.keyCode == Keyboard.DOWN){
thehero.y +=5;
function blockcollision(e:Event):void{
if (thehero.hitTestObject(blockarray[1]))
trace("Hit");
if (thehero.hitTestObject(blockarray[2]))
trace("Hit");

Thankyou very much Andrej for your quick response, it worked perfectly, I can now carry on with my code, thanks again

Need Help With Save As function Very Important

i working on a project and i have to create a Save As function for it. When you click on Save As its supposed to open a dialog window where u can choose the where you would like to save the file and what you would like to name it. I know there is alot wrong with my code but i'm not sure on how to fix it so any and all help is greatly appreciated
private void doSaveAs(){
          //display file dialog
          FileDialog fDialog2 = new FileDialog (this, "Save As...", FileDialog.SAVE);
          fDialog2.setVisible(true);
          //Set the file name chosen by user
          String name = fDialog2.getFile();
          // user canceled file selection, return without doing anything.
          if(name == null)
               return;
          fileName = fDialog2.getDirectory() + name;
          // Try to create a file writer

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

Need help with PL/SQL functions

Hi,
Is there a way to compare if a set of elements is present in another set using some function?
Example: Is it possible to find out if all words present in 'BANQUE SAFRA SA' is present in 'BANQUE JACOB SAFRA (SUISSE) SA' using some function in Oracle 9i?
Any suggestion would be appreciated.
Thank you,
Anushree

Boneist,
your solution would giv "false positives":
SQL> with my_tab as (select 'BANQUE JACOB SAFRA (SUISSE) SA' col1 from dual union all
2                  select 'BANQUE SAFRA (SUISSE) SB' col1 from dual union all
3                  select 'BANQUE SAFRA SA' col1 from dual union all
4                  select 'BANQUE SAFRANE SA' col1 from dual)
5 -- end of mimicking your data. USE SQL below!
6 select * from my_tab
7 where col1 like replace('BANQUE SAFRA SA', ' ', '%');
COL1
BANQUE JACOB SAFRA (SUISSE) SA
BANQUE SAFRA SA
BANQUE SAFRANE SA Here is a PL/SQL funcion that does not expect the words in the specific order:
SQL> DECLARE

Need help with an analytic function I think

I have a table as such:

1 3/13/2009
1 3/13/2009
1 3/13/2009
1 3/14/2009
I need to select a count(*) from this table for EACH day in MARCH, but the table is missing the days of 3/1 - 3/9
I need my result set to be:
BID, POSITIONDATE, COUNT(*)

1 3/12/2009 1
1 3/13/2009 3
1 3/14/2009 1
I thought LAG would do it but I cannot figure out how to get it to "make up the dates of 3/1-3/9 since those dates aren't actually in the table)
I also tried creating a "FAKE" table (T1) with the dates of 3/1 -> 3/31 and outer joining to it, but that didn't seem to work either.
Any tips/suggestions??

I probably should change the variable to MM/YYYY and leave out day I guess, because if they put a day larger than 1, then I would end up with less than a full month.

Need help with an arrays program

this is the task
1.instantiate an array to hold integer test scores
2.determine and print out the total number of scores
3.determine whether there are any perfect scores (100) and if so print student numbers (who received these scores)
4.print out only the scores that are greater or equal to 80
5.calculate the percentage of students that got scores of 80 or above (and print out)
6.calculate the average of all scores (and print out)
heres the code that i came up with
int [] scores = {79, 87, 94, 82, 67, 100, 98, 87, 81, 74, 91, 59, 97, 62, 78, 66, 83, 75, 88, 94, 63, 44, 100, 69, 87, 99, 76, 72};
int total=scores.length;
System.out.println("The total number of scores is: "+total);
for (int i=0;i<=scores.length;i++)
System.out.println(scores);
step 2 is as far as i got
i got stuck at step 3, i cant figure out how to do that
reply plz, ty

3.determine whether there are any perfect scores (100) and if so print student numbers (who received these scores)This question strongly suggests that the data contains information about students associated with each of the test scores. As you have illustrated it, part 3 is simply not doable. There must be more to the assignment than you have said.
Do one thing at a time and make sure your code compiles and runs as you expect before moving on. The code you have posted looks OK for the first couple of steps, but its it's impossible to say unless you post something that's runnable.
(A small thing - but very much appreciated - can you please post code using the "code" tags? Put {code} at the start of your code and again at the end. That way the code will be nicely formatted by the forum's astounding software.)

Need help with an array project please =)

I'm having trouble figuring out where to start. My project is to create an applet that accepts 20 numbers from a text field one by one and adds them to an array. The numbers have to be between 10 and 50 or else the applet shouldn't include them in the 20 but duplicates should be included in the 20. The applet then has to display all the numbers except for duplicates. example:
user inputs:
10,11,12,13,14,15,16,16,16,17,18,19,20,20,20,21,23,24,25,26
applet detects that 20 numbers have been entered and displays them exluding duplicates:
10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 23, 24, 25, 26
If the user imputs a number like 72 I need to make it alert them that the number was not in the 10-50 range and not add that number to the total 20.
I'm not asking anyone to do this for me, I'm just asking for tips on where to get a good start.
Thanks!

//i haven't tryed that code, and it might not work
// anyhow, just in case, i'll also say that this is not an applet
public class NoDublicates {
public static void main(String[] args) {
if (args.length < 20) {
   System.out.println("usage:\njava NoDublicates "
     + "<and 20 space separated numbers from 10 to 50 here>");
   System.exit(1);
byte[] nums = new byte[args.length];
int i = 0;
for (int j = 0; j < args.length; j++) {
   try {
    int temp = Integer.parseInt(args[j]);
    if (temp <= 50 && temp >= 10) {
     nums[i++] = temp;
   } catch (NumberFormatException nfe) {
    // very bad exception, i think i'll ignore it
if (i != 20) {
   System.out.println("it seems that i didn't get exactly 20 "
    + "parseable numbers as arguments, let's exit now.");

   old = nums[j];
}

Need help with oscillating grow function in effects

I am using the grow effect on a mouse over instead of a
click. I used the same code that was used in the example
distributed with the Spry 1.6 release. In the example it used an
onmouseclick. I am using an onmouseover and onmouseout to grow and
shrink the images.
At first I used one function and just called the same
function for onmouseover and onmouseout and specified the toggle
option. The problem with this, is that the image can get "stuck"
into the reverse state, and as you mouseover it shinks and
onmouseout it grows.
So I used two different functions for onmouseover and
onmouseout. One grows and the other shrinks. This works ok if you
use the toggle option set to true on at least one of the two
functions. The problem is that you can still get one of the images
stuck in the wrong size and it toggles the wrong way. If you set
them both to false, the image oscillates between the two states as
you mouseout. I assumed that setting toggle to false for both the
grow and shrink would avoid images stuck in the wrong direction,
but it is causing this strange oscillation. Am I using this option
wrong?
Thank you in advance for any clues you can provide....
Here are my code snippets:
on the Page:
<div class="thumbnails"><div><img height="24"
alt="your friend's icon" onmouseover="toggleThumbU(this)"
onmouseout="toggleThumbD(this)" id="img${status.index}"
style="padding:2px;" src="${contact.imageUrl}"
/></div></div>
In my Javascript code:
var effects = [];
function toggleThumbU(targetElement)
if (typeof effects[targetElement.id] == 'undefined')
effects[targetElement.id] = new
Spry.Effect.Grow(targetElement, {duration: 200, from: '100%', to:
'340%', toggle: false, setup:setzindex, finish:resetzindex});
effects[targetElement.id].start();
function toggleThumbD(targetElement)

I have the same issue, anyone know a way around this? I have
a image i wish to grow onmouse over, then using the same behavior
but shrink with mouseout, it gets some wierd issues, like if you
put the mouse in between it oscillates back and forth, its not
smooth.

Need help with an array function
