Web Reference: Jul 11, 2025 · The HashSet remove () method in Java is used to remove a specific element from the set if it is present. Note: HashSet and the remove () were introduced in JDK 1.2 as part of the Collections Framework and are not available in earlier versions of Java (JDK 1.0 and JDK 1.1). If an entry is removed via Set.remove () while an iteration is being done, you will get a ConcurrentModificationException. On the other hand, removal of entries via Iterator.remove () while iteration is supported in this case. The HashSet.remove() method in Java provides a way to remove a specified element from a HashSet, if it is present. This method is useful in various scenarios, such as managing active users in a web application or maintaining collections of unique elements.
