Quick Answer
Avoid deadlocks: always acquire multiple locks in the same consistent order across all threads. Use tryLock() with timeout instead of lock() - if timeout expires, release what you have and retry. Minimize lock scope and duration. Use lock-free data structures (AtomicInteger, ConcurrentHashMap) when possible. Use a single lock instead of multiple locks when feasible. Detect with thread dumps (jstack).
Answer
Acquire locks in a consistent order. Avoid nested locks where possible. Use tryLock() or timed locks. Prefer higher-level concurrency utilities.
