1. Object level lock in Java Object level lock is mechanism when we want to synchronize a non-static method or non-static code block such that only one thread will be able to execute the code block on given instance of the class. This should always be done to make instance level data ...
Note that it doesn't matter what lock you use to synchronize on, as long as it is the same lock for all instances. We could also have used Object.class (which is also visible to all instances of Example) or even String.class or some static Object field in Example: publicclassExample ...

主要学习多线程的并发访问,也就是使得线程安全。 同步的单词为synchronized,异步的单词为asynchronized 同步主要就是通过锁的方式实现,一种就是隐式锁,另一种是显示锁Lock,本节主要研究隐式锁synchronized的使用。 每个Java对象都可以用作一个实现同步的锁,注意前提
