Java HashSet.remove() is a method in the Java HashSet class that removes the specified element from the set. If the element is present, it is deleted, and the method returns true; if not, it returns false. Introduced in Java 1995 with Java 1.2, remove() is commonly used in Java applications to modify sets by eliminating specific items.
