Passing the array into actionPerformed method
Hi friends! I am new at java. I made a tictactoe game board with GUI and it is designed according to nxn (desired any n value). When I pressed to any button, it should write an X to my board but I could not passed the button's action. My problem is that my actionPerformed method does not accept array button[j]. In the below there is a part of my code :
for(int j=0;j<button.length;j++) // adding the buttons
button[j].addActionListener(this);
public void actionPerformed(ActonEvent evt)
// what can I read here for detecting the right button? button length is changable, it is depent on what we desire at first.
// I tried this code in this area but it does not work:
// if (evt.getSource()==button[j])
// button[j].setText("X");
// normally, it works if I write every button individually like that:
// button1.addActionListener(this); (same for other buttons)
// public void actionPerformed (ActionPerformed evt)
// if (evt.getSource()==button1)
// button1.setText("X"); (same code for other buttons)
// but I want to make a generalized board action
}I will be appreciated with your helps...
MustyHi musty4284,
The getSource method of ActionEvent(not ActonEvent) returns an object and the way you're comparing objects is wrong.
Theorically, you should do something like this :
public void actionPerformed(ActionEvent evt) {
JButton b = (JButton) evt.getSource();
if ( button[j].equals(b) ) {
}Edit :
When using a listener for an array of JButton, it is a good idea to give a unique identifier to each button (for example, their index in the array). The JButton class has a setName method not to confuse with the setText method.
While building your array of JButton, you can do :
JButton[] button = new JButton[9];
for (int i = 0; i < 9; i++) {
button[i] = new JButton();
button.setName(i);
While handling the event :public void actionPerformed(ActionEvent evt) {
JButton b = (JButton) evt.getSource();
int index = Integer.parseInt(b.getName());
button[index].setText("X");

Passing an array of objects to a method.
Hi I'm building a program to act as a CD Collection Database. An array of objects represents the entries: Artist, Album and NUmber of Tracks. What I want to do is in the Menu, user to choose wether he or she wants to Add new CD to collection, print or quit, if he/she does then I call a method addNewEntry, to which i pass the array of objects called array, and I want the user to enter the entries each in turn, after that i want the program to return to the method Menu and ask if he or she wants to quit, print or add new cd. The idea is that the details entered already would be contained in the array of objects [0], so the next set of details go to [1] and then to [2] and so on. I have build up the code at this stage but i get an error while copmiling and im totally stuck. Im a beginner in Java.

Passing split array to function
Anyone know how to pass an array to a function as seperate
parameters i.e
_array = [param1,param2,param3]
functionToCall(param1,param2,param3)
instead of: functionToCall(_array[0],_array[1],_array[2]);
of having to go
var1 = _array[0];
var2 = _array[1];
var3= _array[2];
functionToCall(var1,var2,var3)
Cheers, burnsideDCIBurnside,

array?
That would only work if the desired function is written to
accept two
parameters formatted as arrays. DCIBurnside could certainly
write an
intermediary function, I suppose; but for that effort, it
would be just as
easy to pass in the parameters as already shown:
functionToCall(_array[0],_array[1],_array[2]);
Check out the methods of the Fuction class -- in particular
Function.apply() -- which might be exactly what DCIBurnside
is looking for.

I am very new to java and my instructor gave us an assignment of doing a matching game using JButtons and an applet. I have 2 separate .java files (MemoryApplet.java and MemoryGame.java). MemoryApplet intializes the applet and passes an array of images to a method using the following code...
icon = new MemoryGame();
for(int i = 0;i<6;i++)
imgArr[i] = getImage(getCodeBase(),"img" i".jpg");
icon.setTheIcons(imgArr);
In the MemoryGame file my setTheIcons method looks like this...
public void setTheIcons(Image icon1[])
The problem I am having is that I cannot convert the Image to an ImageIcon to put the image on the JButton. When I passed each image by itself not using an array, it worked fine, but I want to randomize the image locations so I thought passing the array would be the way to go. Any help would be greatly appreciated.
Thanks, ChadIf you want to use those images in JButton, so use the ImageIcon arrays like this:
MemoryApplet
// declare ImageIcon array
ImageIcon[] imgArr = new ImageIcon[6];
for(int i = 0;i<6;i++)
// create new ImageIcon
// path: path of images
imgArr[i] = new ImageIcon(path + "img" + i + ".jpg");
// initialize MemoryGame instance and call method
icon = new MemoryGame();
icon.setTheIcons(imgArr);Hope this help

Passing an array of integers to a method...
here's the case, i have 2 array of integers parent and child. how can i pass the arrays in a method so i can evaluate the contents of both arrays?
here's the block of the code that contains what i'm talking about.
for(int i=0; i<tree.length; i++) {//separate child from parent
int[] parent = new int[(tree.length()/2)];
int[] child = new int[(tree[i].length()/2)];
for(int j=0, ctr=0; j<tree[i].length(); j++, ctr++) {
parent[ctr] = Integer.parseInt(Character.toString(tree[i].charAt(j))); //get the parents
j++;
child[ctr] = Integer.parseInt(Character.toString(tree[i].charAt(j))); //get the children
if(isTree(parent, child)) //evaluate if case is a tree
System.out.println("Is a tree");
else
System.out.println("Is not a tree");
}//separate child fronm parentgeez, thanks... adding "static" did work.. >_< my bad, i'm new in java... and i'm sorry for calling you
"sir", thanks a lot monica... ^^ by the way, it's 1:00 pm here asia.I'm glad it worked--do you understand what "static" means here?
No problem about the "sir". I usually use "he" myself, if I don't know whether it should be he/she. And, around here on the forum (and software engineers at most companies), there are certainly more men than women. People tend to look at MLRon and assume my name is "Ron", but that's my last name. :)
You don't need to call people "sir" or "ma'am" here. Just names or screen names (like MLRon) will do. :)
Have a nice afternoon, then! -

Hi,
I want to pass two arrays over a http connection based on a users action i.e. clicking a button. I have ASP on my server (server side javascript). Can anyone give any help? Would I go about putting the array into a byte array as with other standard string and int variables?
byte[] data = (("array1_="+(sRRowArray)+"&"+"array2_="+(sRSeatArray)).getBytes());I have tried this to no avail.
Is there anything other than request.form that I have to use on the server side to get the arrays?
Thanks in advance,
HarryAny help would be much appreciated!! Would I have to pass the array in a similar way in which images are sent over http? If so, does anyone have any examples of doing this. I need help on this problem urgently.
Thanks in advance,
Harry. -
Problem passing multiple array lists to a single method
Hi, all:
I have written a generic averaging method that takes an array list full of doubles, adds them all up, divides by the size of the array list, and spits out a double variable. I want to pass it several array lists from another method, and I can't quite figure out how to do it. Here's the averager method:
public double averagerMethod (ArrayList <Double> arrayList) {
ArrayList <Double> x = new ArrayList <Double> (arrayList); //the array list of integers being fed into this method.
double total = 0;//the total of the integers in that array list.
for (int i = 0; i < x.size(); i++) {//for every element in the array list,
double addition = x.get(i);//get each element,
total = total + addition; //add it to the total,
double arrayListSize = x.size();//get the total number of elements in that array list,
double average = total/arrayListSize;//divide the sum of the elements by the number of elements,
return average;//return the average.
}And here's the method that sends several array lists to that method:
public boolean sameParameterSweep (ArrayList <Double> arrayList) {
sameParameterSweep = false;//automatically sets the boolean to false.
arrayList = new ArrayList <Double> (checker);//instantiate an array list that's the same as checker.
double same = arrayList.get(2); //gets the third value from the array list and casts it to double.
if (same == before) {//if the third value is the same as the previous row's third value,
processARowIntoArrayLists(checker);//send this row to the parseAParameterSweep method.
sameParameterSweep = true;//set the parameter sweep to true.
if (same != before) {//if the third value is NOT the same,
averagerMethod(totalTicks);//go average the values in the array lists that have been stored.
averagerMethod(totalNumGreens);
averagerMethod(totalNumMagentas);
sameParameterSweep = false;
before = same; //problematic!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
return sameParameterSweep;
}Obviously, the problem is that I'm not passing the array lists from this method to the averager method the right way. What am I doing wrong?Encephalopathic wrote:
There are several issues that I see, but the main one is that you are calculating average results but then just discarding them. You never assign the result to a variable.
In other words you're doing this:
averagerMethod(myArrayList); // this discards the resultinstead of this:
someDoubleVariable = averagerMethod(myArrayList); // this stores the resultAlso, do you wish to check for zero-sized array lists before calculating? And what would you return if the array list size were zero?So in solving that problem, I've come up with another one that I can't figure out, and I can't fix this problem until I fix that.
I have several thousand lines of data. They consist of parameter sweeps of given variables. What I'm trying to do is to store pieces of
data in array lists until the next parameter adjustment happens. When that parameter adjustment happens, I want to take the arraylists
I've been storing data in, do my averaging thing, and clear the arraylists for the next set of runs under a given parameter set.
Here's the issue: I'm having the devil of a time telling my application that a given parameter run is over. Imagine me doing stuff to several variables (number of solders, number of greens, number of magentas) and getting columns of output. My data will hold constant the number of soldiers, and for, say, ten runs at 100 soldiers, I'll get varying numbers of greens and magentas at the end of each of those ten runs. When I switch to 150 soldiers to generate data for ten more runs, and so forth, I need to average the number of greens and magentas at the end of the previous set of ten runs. My problem is that I can't figure out how to tell my app that a given parameter run is over.
I have it set up so that I take my data file of, say, ten thousand lines, and read each line into a scanner to do stuff with. I need to check a given line's third value, and compare it to the previous line's third value (that's the number of soldiers). If this line has a third value that is the same as the previous line's third value, send this line to the other methods that break it up and store it. If this line has a third value that is NOT the same as the previous line's third value, go calculate the averages, clear those array lists, and begin a new chunk of data by sending this line to the other methods that break it up and store it.
This is not as trivial a problem as it would seem at first: I can't figure out how to check the previous line's third value. I've written a lot of torturous code, but I just deleted it because I kept getting myself in deeper and deeper with added methods. How can I check the previous value of an array list that's NOT the one I'm fiddling with right now? Here's the method I use to create the array lists of lines of doubles:
public void parseMyFileLineByLine() {
totalNumGreens = new ArrayList <Double>();//the total number of greens for a given parameter sweep
totalNumMagentas = new ArrayList <Double>();//the total number of magentas for a given parameter sweep.
totalTicks = new ArrayList <Double>();//the total number of ticks it took to settle for a given parameter sweep.
for (int i = 8; i < rowStorer.size() - 2; i++) {//for each line,
checker = new ArrayList <Double>();//instantiates an array list to store each piece in that row.
String nextLine = rowStorer.get(i); //instantiate a string that contains all the information in that line.
try {
Scanner rowScanner = new Scanner (nextLine); //instantiates a scanner for the row under analysis.
rowScanner.useDelimiter(",\\s*");//that scanner can use whitespace or commas as the delimiter between information.
while (rowScanner.hasNext()) {//while there's still information in that scanner,
String piece = rowScanner.next(); //gets each piece of information from the row scanner.
double x = Double.valueOf(piece);//casts that stringed piece to a double.
checker.add(x);//adds those doubles to the array list checker.
catch (NoSuchElementException nsee) {
nsee.printStackTrace();
//System.out.println("checker contains: " + checker);
processARowIntoArrayLists(checker);//sends checker to the method that splits it up into its columns.

I have to pass a javascript array to my java MyAction.do . So how can i do it???
Thnking YouBeing a Java newbie, I can't give you a definitive on how to pass the array to a client-side applet, although it should be possible.
As for passing it to something server-side there are only a couple ways: in a GET request on the query string or in a POST. No matter what, you will have to flatten the array with some method or other, to convert it into a text string that can be parsed on the other end.
I personally favor using hidden form elements and posting the data, because otherwise you have to worry about urlencoding your query string. You could just use javascript itself to write a series of hidden text inputs and then submit the form, so all your form handler has to do is pick up the variables.
Let's say the array is named "myarray":
Code:
+<script language="Javascript">+
document.writeln("<form name=\"myform\" method=\"POST\" action=\"myserver/myhandler.jsp\">")
for(i = 0; i < myarray.length; i+){+
document.writeln("<input type=\"hidden\" name=\"myarray[" i + "]\" value=\"" + myarray[i] + "\">")+
+}+
+document.writeln("</form>")+
+document.myform.submit()+
+</script>+
I know this is clunky and "low-tech" but it will work, and has the benefit of working for any server-side platform that can handle forms -
Hallo every body,
i have some questions when i am passing the refernces to the sub_VI
1)when i run the application, the blink indicator(in main VI) starts blinking. even in sub_vi for true case i set it true and for false case i set it false. why from begining of the execution it starts blinking?
2)the stop button i am using in main VI is too slow. when i press the stop button it takes too much time to stop the application. why?
3)the array control (amplitude, freq,total time taken )
i am creating references of array. then these references i am sending to for loop. where it will convert as scalr values and then these scalar values to the sub_vi. opposite to it i am getting the reference of scalar cycles value and i am buliding an array of these scalar cycles to show it in indicator. it seems not to be working properly. why?
for this exexution some times i get error 91.
4) sometimes in the begining i get error 1055. why?
5) my sub vi crashes not deterministically.some time times after 2 minutes. some times after 5 minutes. by crash i mean i dont get an error but on the oscilloscope i see not smooth sine signal, but some strange broken, unbroken, delayed(all together mixed signals). why?
thanks for the important suggestions.
Regards
Attachments:
Check0.llb 204 KB1) At some point the Blinking property gets set. Then the errors result in the program terminating. The property never gets reset. Setting a Property node in the main VI with Blinking = False prevents this.
2) You have 1 second Wait until next multiple delays in both the main and subVI loops. Depending upon which delays have executed when you push the Stop button it can take two seconds or more before all the loops execute again and note the Stop button.
3) The references are to arrays. (Time Taken, Amplitude, Cycles and Frequency) but you are connecting scalar values to the Values properties. Variant does not mean you can connect anything and it will convert to what you want. Once the Type has been set (when the control was created), the property node input matches that type.
4) 5) I never got this far so I cannot explain these errors. However, I suspect that once you fix the others, these will either be fixed also or the cause will become more apparent.

How do I pass an array of structs to a C function using the dll flexible prototype adapter?
What I want to do is pass into a C dll function a variably sized Array of structs of type TPS_Data. My Code compiles but when I run it in TestStand, I get an error -17001; Program Error. "Cannot allocate 0 size buffer Error in parameter 2, 'OpenFrdData'."
I've allocated the Array of structs, and all of the information is there before I call my function, so is it my prototype? Or am I asking too much of the DLL Flexible Prototype Adapter to pass an Array of Structs?
I can pass in a single struct of type TPS_Data and that works, but not an array.
Here's the relevent code:
typedef struct TPS_DATA
char Report_Number[256];
char System_Name[256];
char Open_Date[256];
char UUT_Part_Number[256];
char UUT_Serial_Number[256];
char UUT_Name[256];
char Open_Employee_Name[256];
char Open_Employee_Number[256];
char Close_Employee_Name[256];
char Close_Employee_Number[256];
char Close_Date[256];
} TPS_Data;
typedef struct TPS_DATA_ARRAY
TPS_Data DataRecord;
} TPS_DataArray;
long __declspec(dllexport) __stdcall OpenDialog (CAObjHandle Context, TPS_DataArray *TpsData[], const char *psFaultStr, char *sComments, const int nCount);OK,
I can pass the data to the DLL function, using the following types:
typedef struct StringArrayType
char string[10][256];
} StringArray;
typedef struct MultiStringArrayType
StringArray Record[10];
} MultiStringArray;
void __declspec(dllexport) __stdcall ATP_TestStructPassing(StringArray Strings)
return;
void __declspec(dllexport) __stdcall ATP_TestMultiStructPassing(MultiStringArray *Strings)
return;
But when the MultiStruct function Exits, TestStand reports an Error:
-17501 "Unexpected Operating System Error" Source: 'TSAPI'
There doesn't seem to be a way around this, and once the error occurs, I have to force quit TestStand. I've included the sequence file, and the dll code can be compiled from the fun
ctions shown above.
Any thoughts on how to get around this error would be greatly appreciated.
