Yes, i figured out the problem. After i declared the vector as static my issue was resolved.

Thanks a lot,
Asha

Hi All,

I have a method getPosition(String ignoreText) which is called from other methods.
I want to store the value of ignoreText at every invocation method getPosition in a vector

For e.g.: if getPosition is called this way
getPosition("Test1");
getPosition("Test2");
getPosition("Test3");

Then the vector should contain the values Test1, Test2, Test3

I have tried with the following code snippet, however the temp vector stores only the current value of ignoreText.
Please let me know how to do this.

public class Checker { Vector temp = new Vector(); public Vector getPosition(String spellText,String ignoreText) throws Exception { temp.addElement(ignoreText); for(int i=0;i<temp.size();i++) { System.out.println("Values of temp "+temp.elementAt(i)); } } }

Thanks,
Asha>

The stack trace is as follows

Exception occurred during event dispatching:

java.lang.StackOverflowError

at tomsawyer.editor.TSENode.setTag(Unknown Source)

at tomsawyer.editor.TSEAnnotatedUI.onTextChanged(Unknown Source)

at asha.builder.graph.CCTImageNodeUI.onTextChanged(CCTImageNodeUI.java:293)

at tomsawyer.editor.TSENode.setTag(Unknown Source)

at tomsawyer.editor.TSEAnnotatedUI.onTextChanged(Unknown Source)

at asha.builder.graph.CCTImageNodeUI.onTextChanged(CCTImageNodeUI.java:293)
.
.
.

Now the problem is to find the caller of the method onTextChanged.
Please suggest.

Thanks,

Hi All,

I have a code snippet(part of our product) which is throwing StackOverflowError(only at the customer's instance).
Based on the stack trace, i figured out that onTextChanged method of CCTImageNodeUI.java is called N number of times due to which this exception is caused.
To further analyze this issue, i need to check who is calling onTextChanged method.
I executed a grep command within our product to check the file which is calling this method, but could not find anything.
The comment says that, this method is called whenever the text of the owner object is changed, however i could not understand how to find the owner object.

package asha.builder.graph; import java.awt.*; import java.awt.image.ImageObserver; import java.io.InputStream; import javax.swing.ImageIcon; import tomsawyer.util.TSProperty; import tomsawyer.util.TSTransform; import tomsawyer.util.TSList; import tomsawyer.editor.*; public class CCTImageNodeUI extends CCTRectNodeUI implements ImageObserver { // Section: Text and font handling //---------------------------------------------------------------------- /** * This method is called whenever the text of the owner object is * changed or the owner object changed. * The method also changes a null text, or text of length 0, * to the default text. */ protected void onTextChanged(String newText) { super.onTextChanged(newText); this.updateTextSize(); this.growAtUserRequest(); } }

Please let me know if there is anyway to find out who is calling onTextChanged method.

Thanks in advance,
Asha

Hi All,

From customer's instance there is an exception: Exception occurred during event dispatching java.lang.StackOverflowError
Anyone please let me know, what does it mean by Exception occurred during event dispatching or point me to any link/doc which explains this.

Thanks in advance,

The problem is to traverse through the HTML string and extract only the string, this extracted string would be later replaced by another one.
The string is entered by the user and this could be even in this way.

This<i><b>is</i></b>For<i>Testing</i>


Please let me know if there any way to extract only the string.

Thanks in advance,
Asha

Hi All,

I have HTML string, for instance

<i><b>Testingfg</b>/i>

There could be some more tags present and also the string could be anything.

Now i have to write a java code to replace the string(Testingfg in this case) with another string like Testing.


One way to solve this is by using pattern match and then replace. Please let me know how to write a regular expression in this case or if there is any way to do this.

Thanks in advance,
Asha

oh i guess it was running with an older version of .class file
Thanks a lot

Yes i think both are int(32 bytes) so the memory consumption should be the same.

Hi Dolly,

You need to drag the boxes from the bottom tray and drop them at required places.

Yes Dolly if i know the answer to your question i can surely help you out

Hi Dolly,

I got the output by executing on my machine..yes even i am using the same mock exam.Even i thought the output should have been "atto".
But after executing this code i found that
String s7 = sb.toString().substring(1, 5);
gives magically this output "rattbFoar", i wanted to know how toString() function performs.

Asha

I wrote this piece of code
line 1: StringBuilder sb = new StringBuilder("Foo"); line 2: sb.append("bar").delete(2, 4).reverse().insert(2, "tt"); //rattoF line 3: String s7 = sb.toString().substring(1, 5);rattbFoar line 4: s7.toUpperCase(); line 5: System.out.println(s7);

Till line no.2 i understood the output, but line no.3 output i didnt understand how the output is rattbFoar.
pls someone explain me

Hi All,

I had seen a thread in one of the Forums in Javaranch where Post-Increment operator was discussed in detail with the stack diagrams by Corey, i had seen that few days back, now i dont know how to find. please reply if anyone has the link of that thread.

Thanks,
Asha

ok i got it thanks a lot
