ReentrantLock source code analysis for Java concurrent Series Before Java5.0, only synchronized and volatile can be used to coordinate access to shared objects. We know that the synchronized keyword implements the built-in lock, while the volatile keyword ensures the multi-thread memory visibility. In most cases, these mechanisms work well, but cannot implement s
