How to Handle Concurrent Modification Exception in Java Streams with Collections?
I'm trying to figure out I'm working on a project and hit a roadblock... I'm currently using Java 11 and dealing with a situation where I need to process a list of items concurrently using Java Streams. However, I'm encountering a `ConcurrentModificationException` when my stream operation attempts to modify the collection. Here's a simplified version of what I'm trying: ```java List<String> items = new ArrayList<>(Arrays.asList("apple", "banana", "orange", "grape")); items.stream().forEach(item -> { if (item.equals("banana")) { items.remove(item); // This line throws ConcurrentModificationException } }); ``` I've tried using `Collections.synchronizedList` to wrap my list, but that didn't help. I also attempted to collect the items to be removed in a separate list and then operate on the original list after the stream operation, but that feels inefficient. Can anyone suggest a clean way to modify a collection while using Java Streams without running into the `ConcurrentModificationException`? Is there a better design pattern I should consider for this scenario? My development environment is Ubuntu. I'm working on a application that needs to handle this. Any help would be greatly appreciated! This is for a application running on Ubuntu 20.04. Could this be a known issue?
