string pooland we don’t want to lock a string that might be getting used by another piece of code. So I am using an Object variable. Learn more about synchronization andthread safety in java. You can checkout more Java examples from ourGitHub Repository. While we believe that this conten...
We can slightly improve the thread-safe implementation of the Counter class by exploiting another object as a monitor lock, instead of this. 我们可以通过将另一个对象用作监视器锁而不是 this ,来稍微改善 Counter 类的线程安全实现。(那么这个对象和this有和不同呢) Not only does this provide coordin...
Simple Singleton Pattern: (Lazy Initialization + ThreadSafe with synchronized block) This implementation uses the same double-checkedlockingmechanism as in the previous implementation. The addedlogging statementshelp demonstrate when the instance is being created and returned. packagecom.crunchify.tutorials; ...
I would agree that this would a bit too extreme for someone who is starting to learn java. But for someone a bit experienced who will understand what is happening and need a bit more speed, the second implementation is definitely the way to go. Moreover, most of the time when doing ...
implements this interface, you will be guaranteed that no two threads will simultaneously execute your servlet’sservice()method. Remember,service()is the underlining implementation for both thedoGet()anddoPost()methods, so we’re safe. The following code snippet illustrates this interface’s usage...

In this paper we present an implementation of Software Cache for the STMicroelectronics STHORM many-core accelerator, featuring a L1 TCDM shared by 16 processors in a cluster. Our main contribution is the design of a fast and thread-safe cache allowing parallel access from different processing ...

We can revisit this for 3.13 if it turns out to be an issue in practice.Post 3.13 we would like to change the underlying lock to be a PyMutex and replace the implementation with something like:static PyObject * lock_PyThread_release_lock(lockobject *self, PyObject *Py_UNUSED(ignored))...
Does NullPointerException occurs only in multi thread execution? At least it's the only time I've ever seen them. Member slawekjaranowski commented Nov 15, 2019 Current implementation of key retrieval is not thread safe. It may occurs that two separate thread try to download and save the ...
