Java: How to remove elements from a list while iterating over/adding to it

Question

This question is a more special case of the problem described (and solved) in this question.

I have two methods, stopAndRemove(ServerObject server) and a close() met

Answer 1

Perhaps this is the wrong way to do it, but I always create a removal collection, which contains indexes or references to the objects that need to be removed. I then iterate over that collection and remove those indexes/objects from the original collection. Probably not the most efficient but it got the job done.

Instead of

for(Collection things : thing)  
    things.remove(thing)

I use

Collection toRemove = new LinkedList();
for(things : thing)
    toRemove.add(thing);

for(toRemove : thing)
    things.remove(thing)
