Monitor problem

[Marcelo]

Hello,

I have a problem with a Monitor implementation. I would like to have a
linkedList with many threads inside (for dumping Images from urls).

However, whenever I launch many threads in parallel I get an out of
Memory problem (which is normal because of the size of the images I
suppose...).

I would like to launch 10-15 threads in parellel and then let the other
threads to just wait in the linked list.

while(condition to only have 10-15 threads){
get Element from list
launch thread
}

However, i just don't know when my threads finish. How can I do it?
Do you have an idea?

thank you very much for your help,

Marcelo

simple in your class with the will loop (called class A for now.) you
have an declaration like this: private int threadsRunning =0; and 2
synchronized functions:

public synchronized void void startThread() {
threadsRunning++;
}

public synchronized void void endThread() {
threadsRunning--;
}

and you have your threads call endThread when they end and call
startThread as you start.
