Discover the importance of lock-free data structures in Java and how they improve performance and scalability in concurrent programming. Learn how they enable efficient thread management without the overhead of locks.
A ConcurrentHashMap in Java is a thread-safe, high-performance map that allows concurrent reads and updates by multiple threads. It is ideal for use cases in multithreaded applications where you need safe access to a map without synchronization bottlenecks. This article explains its design, how it works, and why it is an essential part of Java’s concurrency toolkit.
