ReentrantLock.toString介绍

[英]Returns a string identifying this lock, as well as its lock state. The state, in brackets, includes either the String "Unlocked"or the String "Locked by" followed by the Thread#getName of the owning thread.
[中]返回标识此锁及其锁状态的字符串。括号中的状态包括字符串“Unlocked”或字符串“Locked by”，后跟所属线程的线程#getName。
