Article Introduction：Lock-Free data structures enable thread safety through atomic operations and CAS, rather than traditional blocking locks. Its core lies in lock-free but orderly, relies on CPU instructions such as CAS and FAA, and is implemented using Java's atomic package class, which is suitable for high concurrency scenarios such as queues, counters, etc. When implementing, you need to pay attention to ABA issues, memory order, loop retry overhead and debugging difficulty. Practical steps include familiarizing yourself with atomic classes, learning CAS principles, reading open source code, small-scale experiments and multi-test verification.
