ArrayIndexOutOfBoundsException


private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {

String Temp = jComboBox1.getSelectedItem().toString();

testcomm.TestForm.WriteParamToPic("c"+Temp);

}

public static void WriteParamToPic(String ParamIn)
{
char [] WriteParam = new char[4];
byte [] FinalWriteParam = new byte[4];
WriteParam = ParamIn.toCharArray();
for(int i=0; i<4; i++){
FinalWriteParam[i] = (byte) WriteParam[i];
Comm.PutPointerData(FinalWriteParam,4);
}
}






I have:
jComboBox1.setModel(new javax.swing.DefaultComboBoxModel(new String[] {"30", "50" }));
i get nex error:
java.lang.ArrayIndexOutOfBoundsException


Hove must i configure argument for WriteParamToPic?
I have trayed to change number of arrays in WriteParamToPic, but it returns me other errors.

Thank you

FinalWriteParam[i] = (byte) WriteParam[i];
At this point WriteParam is longer than FinalWriteParam because

  1. WriteParam = ParamIn.toCharArray(); 


is returning an Array os size bigger than 4. You have to decide what you want to do with the surplus bits first to solve that problem

Thank you wery much.I don't get error any more.

But now, I’ll gone to tray to explain next problem. And if we well resolve it, I’ll
be much closer to my final faculty work.

I'm sending data (parameters) to the PIC microcontroller. I have made application for regulation of temperature. And to control and supervise it i need to use a graphic interface. So, from Hyper terminal i can do it wery well.
My PIC understands characters sent from keyboard one by one.

But in my Java work:...
my code doesn’t accurate me valid transmission. I have to press (activate transmission) on button several time to get result and much time the transferred data isn’t correct. I'll appreciate every suggestions because i assume that them well lead me to conclusion have to resolve communication problem.

Now when I think. I have programmed microcontroller to activate interrupt itch time it gets data (one character)on him input. So it could be resolution to include a delay between sending of
characters to give microcontroller time to elaborate data.
Yes , I think this could be wright way. So if I resume I have to send character by character and to include minimum delay between itch transmission.Wright?

To continue before sent code:

Anytime. Notice also that I did not really give you much help here. Just a few comments and you managed to fix the problem yourself. It's always a pleasure assisting those who prefer to write their own code themselves.

Sure, that with yours help it can do more.



My school work is done, but I wont to improve(make beater) it, that it can be used in technical application

for real. So, there is some more work to do.

I have to stop timer and activate it again after other code (data transmission) has been done.



But I get error (comment). What must i do to resolve it? A must admit that theory about static and non static isn't steal clear to me.

What error(comment) are you getting.

// non static metod cannot be referenced from static context

and it referes to next line of code:
testcomm.TestForm.startTimer() ;


it is part of first block of code in previous post.

This may really depend on how you designed your classes, but
what happens if you make the startTimer method static?
Feb 15 '07 #11
First i have changed metod to static and then variable timeSampleLong too.
But i could not resolve next error :
"non-static variable this couldnot be referenced from a static context"
which refers to:
mainTmr.schedule((new TimerChhRunCls()),1000,timeSampleLong);

No that cannot be the line with the error this time. Check again with both startTimer and timeSampleLong declared as static and check the line number for the error and error method.

I have to go in about 30mins or so, so please try to respond soon.

  1. testcomm.TestForm.startTimer() ;
You are trying to call a .startTimer() method from the TestForm class, but it should be called from a Timer. Try

Expand|Select|Wrap|Line Numbers
  1. testcomm.TestForm.mainTmr.startTimer();
or just

  1. mainTmr.startTimer();
Yes. Try this with both startTimer and timeSampleLong declared as non-static.

Now this appeares:
cannot find symbol.
symbol: metod startTimer()
location: class java.util.Timer
when i go with mouse on the error line:
testcomm.TestForm.mainTmr.startTimer();

and when i write "." after:
testcomm.TestForm.mainTmr
there are no startTimer metod to choise it.

If i try with:
mainTimer.startTimer();
it look after only in Setting class


I'm sending class Setting; it's another JFrame from where am i maneging parameters

Ok then. I think we should get it back to having the timer as static. Make the neccessary adjustments to get it back to static and post the error that you are getting. It should be easier now that we have much of the code posted.

But you did not use the variable this, in that method. Are you sure the error refers to that method? Which line does it specifically say has this error?
Feb 16 '07 #22
it's looks that it refers refers to the method TimerChhRunCls
because when i change it to static the error disappears.

but then i have to change other "things" to static; and so on until i get to the JTextField2, which can't be changed.

So i decided to move all from second class to first.
In that way i hope will exclude this problem.

Am working on it now. And in this way i think that it would be even beater.
I have to finish it today because tomorrow i plane to work on text of my thesis.

Probably lately i'll have to fix other things. I have in plan just another thing do do.
To make text of one variable (temperature) been visible near icon Java in task bar.

Thank you again.

For drawing of graph am reading data at specified time drove by timer.
So if i wont to communicate with microcontroler i have to stop timer and then i may read or write value of new parameters and then activate timer again.

I may stop timer but it doesn't mean that i have stop reading data for writing graph and if am trying to deal with parameters system goes in tilt.

I don't wont to complicate with parallel treads.
So if it it could be done in way to activate some flag when graph transmission is active, and make parameter transmission to control that flag. And wit of deactivation of the flag to proceed of parameter transmission.

Something like this:

a =1
read data for graph
a=0


do while( a=1){
wait
}
write or read parameters

I'll continue to work on my application until it well be as i like it.


I have connected the variable of measured temperature to title of JFrame..
So i me see the value of temperature into taskbar near the Java icon.
Maybe the resolution for next problem isn't so complicate.
Hove can i make the title of JFrame to be seen only in taskbar line and not as a title of JFrame window?

Strange requirement and interesting problem too. I'm not sure if it can be solved. stIconImage will set an image to be displayed on the title bar when minimized (depends on the platform). If you can somehow get your temperature into an image that would be it but probably not worth the work required for that.
Feb 19 '07 #26
Maybe it is more simple
to find out have it can be made that title of the frame is visible only when frame is minimized.

Yes this should be possible. Just look up the event for minimised I think it's windowIconified. Would then have to call repaint so the change is reflected and after that call setVisible(false) to minimize it.
Feb 19 '07 #28
I was not able to use repaint and setVisible(false).

But from yours suggestion to use windowIconified
I had got to the next funny code(which also works):

  2. private void formWindowStateChanged(java.awt.event.WindowEvent evt) {

  5.     a=0;
  6.        }
  7. else{
  8.     setTitle("");
  9.      a=1;
  10. }

And laity (because I felt that it must be some way)I found out formWindowDeiconified and the problem was resolved :

  4. setTitle("hallo");
  5. a=0;
  6. }
  7. else{
  8. setTitle("");
  9. a=1;
  10. }

And laity (because I felt that it must be some way)I found out formWindowDeiconified and the problem was resolved :
Thank you

Good work! You'll surely become a very good Java programmer if you keep at it.

Next metod gets data for graph:

Expand|Select|Wrap|Line Numbers
  1. private void ReadTemperatureFromRS232()
  2.     {
  3.         if(readReservated ==0){
  4.         timeReservated =1;
  5.         Data = ReadParamFromPIC('R');
  6.         timeReservated=0;
  7.         buckupData = Data ;
  8.         }
  9.         else {
  10.             Data = buckupData;
  11.         }
  12.         float Dat = Float.parseFloat(Data);
  13.         tseries.addOrUpdate(new Second(new Date()),Dat);
  14.  
  15. private TimeSeriesCollection createDataset()
  16.     {
  17.         TimeSeries ts = new TimeSeries("Actual Temperature", Second.class); 
  18.         TimeSeriesCollection dataset = new TimeSeriesCollection();
  19.         dataset.addSeries(ts);      
  20.         ts.setMaximumItemAge(30*60);
  21.         return dataset;
  22.  
  23.     }
And in this way the graph is drowen:

Expand|Select|Wrap|Line Numbers
  1.  private void DrawGraph()
  2.     {
  3.         dataset = createDataset();
  4.         TCh = new TChartWrite();
  5.         MainChrt = TCh.createChart(dataset);
  6.         MainChartPnl = new ChartPanel(MainChrt);
  7.         MainChartPnl.setBounds(0,0,640,480);
  8.         jPanel1.add(MainChartPnl);
  9.         jPanel1.setVisible( true );
  10.         MainChartPnl.validate();
  11.         tseries = dataset.getSeries(0);
  12.     }
  13.  
  14.  
  15.     }
This code works good.
But i would like to draw another parameter in the same graph. Now i have "Actual" temperature, but i also need "Wished" temperature.
I can use first metod (ReadTemperatureFromRS232()) to get second parameter by line in code: Data2 = ReadParamFromPIC('W');
But then have to integrate it in dataset(tseris). Here is the point where i'm out.

What is the way to reselve this problem?
