Synchronize an iterator in java

[Remedy]

Hello,
I have some code which used hashtable and the enumeration. I converted all the hashtable in treemap and enumeration iterator to return, however, at a specific location.
Here is the code for it

Iterator = it son.keySet().iterator();
            
            while (it.hasNext()) {
               String cleTemp = (String)it.next();
                Fil fl = ((Thread)son.get(cleTemp));
                if (fl.estRelieA(codeElem))    supprimerFil(cleTemp);
            }

I think the iterator is not synchronizing and I am getting an error. If you know the solution for this then please do post back.

Hello,
I am new to this , but I have a code with me, you can try it
See below for the code

Set s = Collections.synchronizedSet(son.keySet()); 
         synchronized(s) {
        Iterator it = s.iterator();
            
            while (it.hasNext()) {
               String str = (String)it.next();
                Fil fl = ((Thread)son.get(str));
                if (fl.est(codeElem))    supprimerFil(str);
            }
         }

Hello,
Alternatively you can try the following

private void supprimerFil(String cdfl)  {
        Fil fl = ((Thread)sn.get(cdfl));
        fl.deconnecterFil(elements, sn);
        Intl srt = fl.getSortie();
        sn.remove(cdfl);
        
        / / We delete isolated nodes
       elmn();
        
        updateGrilleTraces();

Just have a try at it and see if it works , and if not then post back with the error you are getting and we will try to solve it.

Hello,
What I mean Zekey is that during the course of a collection with an iterator, it is forbidden to modify the collection. This is not a timing issue but many multithreaded algorithm.

I am using a fl.remove (key) in the method supfl

Precisely the error comes from there, You should see it

clefsFils.remove();

Hello,
Thanks for the help, I have tried a code please check it and see if it is correct and if you find any problem in the code then guide me.
here is the code:

private void supfl(cdfl String, Iterator clfl)  {
        Fil flsup = ((Thread)son.get(cdfl));
        flsup.deconnecterFil(elements, son);
        Intl srt = flsup.getSortie();
        
        clfl.remove();
        
        / / We delete isolated nodes
        eliminerNoeudsIsoles();
        
        updateGrilleTraces();
    }

Hello,
I am new to this and even I am trying some programs on this, I have a small part of the code , which I have displayed here

synchronized(ls) {
Iterator i = ls.iterator(); // synchronized block
while (i.hasNext())
foo(i.next());
}
