Java CopyOnWriteArraySet is a thread-safe set implementation backed by a Java CopyOnWriteArrayList. It allows concurrent access without synchronization by making a copy of the underlying array every time it is modified. Introduced in Java 2004 with Java 5, CopyOnWriteArraySet is part of Java's java.util.concurrent package and is ideal for scenarios where reads are frequent and writes are infrequent, such as in caching or event-handling systems.
