ConcurrentModificationException is a runtime error that occurs when a thread tries to modify a collection that is being iterated by another thread. It can be frustrating to debug, as often the error message is not very helpful. In this article, we will explore how to avoid ConcurrentModificationException in Java.
There are a few different ways to avoid ConcurrentModificationException. One way is to use the synchronized keyword. The synchronized keyword ensures that only one thread can access a collection at a time. Another way to avoid ConcurrentModificationException is to use a concurrent collection. Concurrent collections are designed to be accessed by multiple threads without causing ConcurrentModificationException.
