How to search in 2d array in different direction

the method will take a string argument and convert them into char and try to find them in a 2d array.
It is more like a word puzzle(wordSearcher).Here's what i've done so far...
public void find(String word)
for(int a = 0; a < word.length(); a++) {
char oneChar = word.charAt(a);
String oneStringchar = String.valueOf(oneChar);
// Searching through in South Direction
for(int i = 0; i < g.length; i++) {
for(int j = 0 ; j < g.length ; j++) {
if (oneChar == g[i][j]) {
canvas.draw(oneStringchar, (i * WORD_SIZE) + POS_X, (j * WORD_SIZE) + POS_Y);

i dont know the code to wrtie a java program that
searches for names and grades in a program...can
anyone write the code that searches for names and
grades in an array?Let me give you some facts:
1. Yes, most of us can.
2. No, most of us are not likely to write that code for you.
3. It makes a difference HOW the names and grades are stored in the array
Is this a 2D array, with names indexed by [0] and grades indexed by [i][1]. Or is this a 1D array with names indexed by [i*2] and grades indexed by [i*2 + 1]?
Or is it two completely separate arrays, with the grades of a person indexed in the same position in a grades array as the names are indexed in the names array.
this makes a big difference as to how you should proceed.
By looking at your post, however, you haven't even given the slightest bit of thought to that, yet, because you didn't post that information.
If you don't at least TRY to figure this out for yourself, you're not going to find much help here.

How to design a microphone array to find direction of sound source using 4472?

I am trying to implement Labview to find the Time delay of arrival of a single sound source. How can do that using NI 4472 DAQ device?

Hi, nil,
First you can use Measurement & Automation Explore to check your hardware. It will appear in My System -> Devices and Interfaces -> NI-DAQmx Devices. Select 4472, and click Test Panels menu. I'm not sure if your microphones need ICP supply, but I guess most of the array microphones need this. So you need to enable the IEPE, and make sure choosing AC Coupling. Change the Acquisition Mode to Continuous. You can test if your microphones is working well one by one.
You can refer to Hardware Input and Output -> DAQmx -> Analog measurements ->Sound Pressure -> Cont Acq Snd Pressure Samples-Int Clk VI.
If you use more that 8 microphones, you have to use more than one 4472 boards. You need to synchonize the signals received by different boards. A good example is Hardware Input and Output -> DAQmx -> Synchronization -> Multi-Device -> Multi Device Sync-AI-Shared Timebase & Trig-DSA VI.

How to Search and Array for multiple occurrences of a value

Hi,
I am trying to search an array of doubles for a number and report the index location(s) of a number. I.e. -allow for repetition. Search and report all index[i] where the number is contained in the array. For example I have
double[] myInputArray = new double[5];
double[] myInputArray = { 1, 2, 3, 3, 5 }I know how to search through the array ONCE and return the first occurrence of a number:
public double GetIndexOf(double Number) {
    for (int i=0; i<myInputArray.length; i++) {
         if (myInputArray[i] == Number){
              return(i);
    return(-1);
}How do I expand this code to report multiple index[i] locations if the number reoccurs in the array like the number 3 does in my example array above?

The way the Java libraries do this type of operation (String.indexOf(), etc) is to specify the starting index along with what you want to find.
Changing your example slightly (notice how I fixed your naming and more importantly, your return type):
public int indexOf(double num) {
   return indexOf(num, 0);
public int indexOf(double num, int fromIndex) {
    for (int i=fromIndex; i<myInputArray.length; i++) {
         if (myInputArray[i] == num){
              return(i);
    return(-1);
//usage to get all indices:
for ( int index = -1; (index = indexOf(num, index+1)) != -1; ) {
   System.out.println(index);
}Note that due to how floating point numbers work, you may find doing this on doubles (or any other operation that uses == with double arguments) to give you unexpected results.

How to search a word in a 2d array

Hi, i'm seeking advice on how to search a word in 2d array. The method will only taking one argument string and will search in row by row, column by column and diagonall down and up. for example, user input String "SEEK" or then the method will have different search pattern to locate the word. Here is the 2d array look like.
S + K E E S + +
E + + + + + + K
E S + + + + + E
K + E + + + + E
+ + + E + + + S
+ + + + K + + +
What i've done so far is;
// this loop is for search SEEK column by column
public boolean finder(String w){
for(int j = 0; j < puzzle[0].length; j++) {
for(int a = 0; a < w.length(); a++) {
char n = w.charAt(a);
String r = String.valueOf(n);
if (puzzle[0][j] != w.charAt(a)) {
return false
} else {
return true;

How to search for particular string in array?

I am struggling to figure out how to search array contents for a string and then delete the entry from the array if it is found.
The code for a program that allows the user to enter up to 20 inventory items (tools) is posted below; I apologize in advance for it as I am also not having much success grasping the concept of OOP and I am certain it is does not conform although it all compiles.
Anyway, if you can provide some assistance as to how to go about searching the array I would be most grateful. Many thanks in advance..

Ok, so you have an array of Strings. And if the string you are searching for is in the array, you need to remove it from the array.
Is that right?
Can you use an ArrayList<String> instead of a String[ ]?
To find it, you would just do:
for (String item : myArray){
   if (item.equals(searchString){
      // remove the element. Not trivial for arrays, very easy for ArrayList
}Heck, with an arraylist you might be able to do the following:
arrayList.remove(arrayList.indexOf(searchString));[edit]
the above assumes you are using 1.5
uses generics and for each loop
[edit2]
and kinda won't work it you have to use an array since you will need the array index to be able to remove it. See the previous post for that, then set the value in that array index to null.

How to compare 2 arrays with different operator options using parameters in Teststand

Pls let me know how to compare 2 arrays using different operators like <= or >= or ==......

I am using TS 2010. FYI
ex:
Array XX [ A_Temp,
               B_Temp,
               C_Oil Pressure,
               D_Oilpressure,
Note : A_Temp, B_Temp,C_Oil Pressure,D_Oilpressure all these parameters will be getting numerical values (dynamically) from the simulink models and also in future I may need to add parameters to this array.
Array YY [A_Temp_1,
               B_Temp_2,
               C_Oil Pressure_3,
               D_Oilpressure_4,
Note : A_Temp_1, B_Temp_2,C_Oil Pressure_3,D_Oilpressure_4 all these parameters will be getting numerical values (dynamically) from the simulink models
So my question :
I would like to verify A_Temp >= A_Temp_1
                            B_Temp >= B_Temp_2
                            C_Oil Pressure >= C_Oil Pressure_3 etc

How to search array of control refs

I have an event case that handles a number of controls of different types in the user interface. I have a global array that holds references to each of several ring controls; I'd like to test whether the control that triggered the event is one of the ring controls.
I can use a while loop, and control the CtlRef for the event to each ref in my global array--that works fine. But it seems that the Search 1D Array operator would be a natural choice, cleaner and likely faster than a while loop. However, I get a type mismatch when I hook the array of ring refs and the incoming CtlRef to the search function. I tried casting to more specific type on the CtlRef--to a ring ref--but that didn't fix it. Any ideas?

tst wrote:
You should have gone the other way. When you have an event common to several types of controls, the CtlRef terminal will use the class common to all those controls, so you should cast the references to the more generic class. The cleaner solution, however, is to use the equal node to compare the array of references to the CtlRef terminal and then search the resulting array for T.
Yes, I did consider that I should be going to more general, but it seemed that I couldn't do that to the array in one shot, so it would have bought me nothing over the sub-optimal solution that already worked. The conversion to the array with the compare node I hadn't considered though, and that's an excellent solution--thank you much :-)

How you search through arrays ?

Hey, how is it that you search through an array of ojects to find a specific value?
Eg
class Buildings
String name;
building [ ] build;
public Buildings ( String name, int max)
name = nam
maximum = max
build = new building[max]
in an abstract class i have an abstract public double getInsuredValue() as a method, so in the
class Flat and House, they both have their own getInsuredValue() method and in another method in the Buildings class I have made a method called
public Building createBuilding()
int type = 0;
for (int i = 0, i< maximum, i++)
if (type = 1)
build = new Flat(address, name, status and others- these are in the construct of the Flat extends Building class)
if (type = 2)
build = new House( address, name, money and others - these are in constuctor of House extends Build class)
Now what I want to be able to do, is search for the highest getInsuredValue() for a particular type of building, eg I know to find it for say all the types were just one building type
eg if it was just
build = new Building() and not ( build = new Flat() aswell as build = new House() you would go
--method name i have to use except ill take out parameter i have to use
public Building findHighestInsuredProperty()
Building highest = build[0]
double highestValue = highest.getInsuredValue()
for (int i = 0; i< maximum, i++)
if(build.getInsuredValue() > highestValue
highest = build[i]
highestValue = highest.getInsuredValue()
return highest;
but the method has a parameter in it called (int buildtype)
so for example if it was int = 1, i want it to just search through the array, look at the Flats and bring back highest, and if int = 2, i want it to look through the House ones and bring back value ? How do I do this? Thanks.

well maybe ive done something wrong before hand
the array is Building [ ] build;
in the class i have a method that adds building to array
public void addProperty (Property leftover)
           if (extra == null || numberofBuilids > maximum)
                    return;
    build[numberOfBuilds] = extra;
    numberof Builds++
     }the next method i want to create a Building instance and return a reference to it
public Building createBuilding()
      String name;
      double type;
      double insu;
      Building build;
         for (int i = 0; i < maximum; i ++)
             name = Keyboard.readString ("Name: ")
            insu = Keyboard.readDouble("Insurance
             type = Keyboard.readBuilding ("type")
    if (type == 1)
               build = new House(name, type)
   if (type == 2)
              buid = new Flat (name, type)
return build;
Is this right and does it add these instance to the array ?

How to search for a value within a tolerance in an array?

I am trying to search in an array for a value of say 10 plus or minus 2. In other words, I want a value of true if there is any value in the array between 8 and 12.

canadian;
LabVIEW includes with a VI called In Range and Coerce. You can test the value using that VI.
I also created a VI for exactly that. You can download it from here:
http://www.jyestudio.com/lview.shtml
It is called Search 1D array using conditions. Let me know if it is useful. Even more efficient, you can look at the code of that VI and then extract the functionality you want for your application.

How to ask for an array and how to save the values

I'm supposed to be learning the differences between a linear search and a binary search, and the assignment is to have a user input an array and search through the array for a given number using both searches. My problem is that I know how to ask them how long they want their array to be, but I don't know how to call the getArray() method to actually ask for the contents of the array.
My code is as follows:
import java.util.Scanner;
import java.util.ArrayList;
public class Main
    private static Scanner input = new Scanner(System.in);
    public static void main (String args[])
        //creates ArrayList
        int List[];
        System.out.println("How long would you like the array to be?");
        int arrayLength = input.nextInt();
        //Initializes array list
        List = new int [arrayLength];
        System.out.println("Please enter the first value of the array");
    public static void getArray(int List[], int arrayLength)
        for(int i=0; i < arrayLength; i++) {
             System.out.println("Enter the next value for array");
             List[i] = input.nextInt();
     public static void printArray(int List[])
         for(int i=0; i < List.length; i++)
             System.out.print(List[i] + " ");
public class search
    public static int binarySearch(int anArray[], int first, int last, int value)
        int index;
        if(first > last) {
            index = -1;
        else {
            int mid = (first + last)/2;
            if(value == anArray[mid]) {
                index = mid; //value found at anArray[mid]
            else if(value < anArray[mid]) {
                //point X
                index = binarySearch(anArray, first, mid-1, value);
            else {
                //point Y
                index = binarySearch(anArray, mid+1, last, value);
            } //end if
        } //end if
        return index;
    //Iterative linear search
    public int linearSearch(int a[], int valueToFind)
        //valueToFind is the number that will be found
        //The function returns the position of the value if found
        //The function returns -1 if valueToFind was not found
        for (int i=0; i<a.length; i++) {
            if (valueToFind == a) {
return i;
return -1;

I made the changes. Two more questions.
1.) Just for curiosity, how would I have referenced those methods (called them)?
2.) How do I call the searches?
import java.util.Scanner;
import java.util.ArrayList;
public class Main
    private static Scanner input = new Scanner(System.in);
    public static void main (String args[])
        //creates ArrayList
        int List[];
        System.out.println("How many values would you like the array to have?");
        int arrayLength = input.nextInt();
        //Initializes array list
        List = new int [arrayLength];
        //Collects the array information
        for(int i=0; i < arrayLength; i++) {
             System.out.println("Enter a value for array");
             List[i] = input.nextInt();
        //Prints the array
        System.out.print("Array: ");
        for(int i=0; i < List.length; i++)
             System.out.print(List[i] + " ");
        //Asks for the value to be searched for
        System.out.println("What value would you like to search for?");
        int temp = input.nextInt();
        System.out.println(search.binarySearch()); //not working
}

How do you create an array without using a shell on the FP?

I want to be able to read the status of front panel controls (value, control box selection, etc.) and save it to a file, as a "configuration" file -- then be able to load it and have all the controls set to the same states as were saved in the file. I was thinking an array would be a way to do this, as I have done that in VB. (Saving it as a text file, then reading lines back into the array when the file is read and point the control(s) values/states to the corresponding array element.
So how do I create an array of X dimensions without using a shell on the front panel? Or can someone suggest a better way to accomplish what I am after? (Datalogging doesn't allow for saving the status by a filename, so I
do not want to go that route.)

Thanks so much m3nth! This definitely looks like what I was wanting... just not really knowing how to get there.
I'm not sure I follow all the icons. Is that an array (top left with 0 constant) in the top example? And if so, that gets back to part of my original question of how to create an array without using a shell on the FP. Do I follow your diagram correctly?
If I seem a tad green... well I am.
I hope you understand the LabVIEW environment and icons are still very new to me.
Also, I had a response from an NI app. engineer about this problem. He sent me a couple of VI's that he threw together approaching this by using Keys. (I still think you are pointing to the best solution.) I assume he wouldn't mind m
e posting his reply and the VI's for the sake of a good, thorough, Roundtable discussion. So here are his comments with VI's attached:
"I was implementing this exact functionality this morning for an application I'm working on. I only have five controls I want to save, but they are all of different data types. I simply wrote a key for each control, and read back that key on initialization. I simply passed in property node values to the save VI at the end, and passed the values out to property nodes at
the beginning. I've attached my initialize and save VI's for you to view. If you have so many controls that this would not be feasible, you may want to look into clustering the controls and saving the cluster as a datalog file.

How do you make an array of image icons and then call them?

How do you make an array of image icons and then call them, i have searched all over the internet for making an array of icons, but i have
found nothing. Below is my attempt at making an array of icons, but i cant seem to make it work. Basically, i want the image to match the value of the roll of the dice (rollVal)
Any help would be greatly appreciated, some code or link to tuturial, ect.

How to search a network/external hard drive in finder?

I use my Macbook at work where I am required to save all files I work on to a network hard drive on our server. I also have to be able to find and access files from the network drive for customers. In Snow Leapord I had the ability to type in the search bar in finder and it would search the entire network drive and find what I was looking for very quickly. Lots of people at work access the network drive, and every one of them has a different sense of organization. The ability to search is an absolute must in order to find anything. After upgrading to Lion, I discovered that the ability to search a networked or external hard drive has been removed. Lion only allows me to search my local hard drive in my Macbook. Does anyone know how to search a network hard drive in Lion? If not I am going to have to eat the 30 bucks and downgrade back to Snow Leopard. I have scoured through every little preference and option and have found nothing that even sounds remotely like it has anything to do with the search feature. Anyone please help, if not I am going to have to break out the time machine backups and remove this broken os from my computer.

system preferences, spotlight, privacy, add the network or external hard drive and then remove it from the privacy list. it should start to reindex this drive. You'll experience some slowness while this is happening and depending on how big your network is, it might take a really long time. But after that, you should be able to search in them as well. You can also organize what types of files show first so you can navigate to them easier.
hope this helps

How to search for a BADI in a transaction

Hi All,
Please let me know the steps to find a BADI for a transaction.
Thanks,
Jaffer Ali.S

check this.
u can find BADI's in different ways...
1>First go to any transaction->iN THE menu bar SYSTEM->STATUS->Get the program name ->double click->u will go to the program attached to the tcode.Now search term will be CALL CL_EXITHANDLER.Now u will get list of BADI'S available..
2>Goto SE24->Give class name as CL_EXITHANDLER->Display->double click on get_instance mathod->Now u will go inside the method->Now put break point on the cl_exithandler.Now go to any transaction code and pass dat..U will see that it will be stopped on the break point which u set on the cl_exithandler...In the exit name u can find list of badi's attached to the tcode..
There are multiple ways of searching for BADI.
Finding BADI Using CL_EXITHANDLER=>GET_INSTANCE
Finding BADI Using SQL Trace (TCODE-ST05).
Finding BADI Using Repository Information System (TCODE- SE84).
1. Go to the Transaction, for which we want to find the BADI, take the example of Transaction VD02. Click on System->Status. Double click on the program name. Once inside the program search for CL_EXITHANDLER=>GET_INSTANCE.
Make sure the radio button In main program is checked. A list of all the programs with call to the BADIs will be listed.
The export parameter EXIT_NAME for the method GET_INSTANCE of class CL_EXITHANDLER will have the user exit assigned to it. The changing parameter INSTANCE will have the interface assigned to it. Double click on the method to enter the source code.Definition of Instance would give you the Interface name.
2. Start transaction ST05 (Performance Analysis).
/people/alwin.vandeput2/blog/2006/04/13/how-to-search-for-badis-trace-it
3. Go to Maintain Transaction (TCODE- SE93).
Enter the Transaction VD02 for which you want to find BADI.
Click on the Display push buttons.
Get the Package Name. (Package VS in this case)
Go to TCode: SE84->Enhancements->Business Add-inns->Definition
Enter the Package Name and Execute.
Here you get a list of all the Enhancement BADIs for the given package MB.
The simplese way for finding BADI is
1. chooes Tcode Program & package for that Tcode.
2. Go to Tcode se18
3. Press F4
4. search by package or by program.

How to search for files using wildcards * and ?.

Hi All,
I've been searching the forum for a couple of hours now and have been unable to find a good example of how to search a directory (Windows OS) for a file using wildcards * and/or ?. Does anyone out there have a good example that they can share with me?
Thanks

Hi All,
First of all I want to thank everyone for taking the time to respond to my question. All of your responses where greatly appreciated.
I took the example code that was posted by rkconner, thanks rkconner, and modified it to allow me to search for files in a directory that contain * and/or ?. Yes, I said and/or! Meaning that you can use them both in the same file name, example: r??d*.t* would find readme.txt.
I've posed my complete and thoroughly document code below. I hope it is very helpful to other as I have searched many forums and spent many hours today trying to resolve this problem.
Enjoy
* File Name: WildcardSearch.java
* Date: Jan 9, 2004
* This class will search all files in a directory using the
* asterisk (*) and/or question mark (?) as wildcards which may be
* used together in the same file name. A File [] is returned containing
* an array of all files found that match the wildcard specifications.
* Command line example:
* c:\>java WildcardSearch c:\windows s??t*.ini
* New sWild: s.{1}.{1}t.*.ini
* system.ini
* Command line break down: Java Program = java WildcardSearch
*                          Search Directory (arg[0]) = C:\Windows
*                          Files To Search (arg[1]) = s??t*.ini
* Note: Some commands will not work from the command line for arg[1]
*        such as *.*, however, this will work if you if it is passed
*        within Java (hard coded)
* @author kmportner
import java.io.File;
import java.io.FilenameFilter;
public class WildcardSearch

          sWild = args[1];   // wild card to use - example: s??t*.ini
          sWild = replaceWildcards(sWild);
          System.out.println("New sWild: " + sWild);
          File fileDir = new File(sExtDir);
          File[] arrFile = fileDir.listFiles(new FilenameFilter()

               System.out.println(arrFile.getName());
     }     // end main
     * Checks for * and ? in the wildcard variable and replaces them correct
     * pattern characters.
