The Java ConcurrentHashMap is a thread-safe implementation of the Java Map interface that allows concurrent access by multiple threads. It is part of Java's java.util.concurrent package and provides a highly efficient way to store key-value pairs in multithreaded environments. Introduced in Java 2004 with Java 5, the ConcurrentHashMap is widely used in applications requiring high concurrency and performance, particularly in distributed systems and caching solutions.
