How does LinkedHashSet behave in multithreaded code?

LinkedHashSet is a part of Java's collection framework that maintains insertion order and allows no duplicate values. When it comes to multithreaded environments, LinkedHashSet is not thread-safe. This means that concurrent modifications from multiple threads can lead to unpredictable behavior, such as missing elements or exceptions. To ensure thread safety, you can consider synchronizing the LinkedHashSet or using alternatives such as ConcurrentHashMap or Collections.synchronizedSet.
