Every object in Java has a built-in lock that only comes into play when the object has synchronized method code. When we enter a synchronized non-static method, we automatically acquire the lock associated with the current instance of the class whose code we're executing. Summary: The synchro...

In other words,it’s a bad practice to use pooled or reusable objects for synchronization. The reason is that a pooled/reusable object is accessible to other processes in the JVM, and any modification to such objects by outside/untrusted code can result in a deadlock and nondeterministic b...
Thread Safe describe some code that can be called from multiple threads without corrupting the state of the object or simply doing the thing the code must do in right order. 即一段代码可以被多个线程调用,调用过程中对象的状态不出现冲突,或者对象按照正确的顺序进行了操作。 i++ 线程安全是指我们读...
In this case, the thread acquires the intrinsic lock for the Class object associated with the class. Thus access to class's static fields is controlled by a lock that's distinct from the lock for any instance of the class. Synchronized Statements Another way to create synchronized code is ...

Synchronization in java guarantees that no two threads can execute a synchronized method which requires same lock simultaneously or concurrently. synchronized keyword can be used only with methods and code blocks. These methods or blocks can be static or non-static both. ...
