A lock is kind of data which is logically part of an object’s header on the heap memory.Each object in a JVM has this lock (or mutex) that any program can use to coordinate multi-threaded access to the object. If any thread want to access instance variables of that object; then thr...
2. ReentrantLock ismore flexiblethan synchronized lock in Java. All other threads trying to get lock is blocked if synchronized lock is not available butReentrantLockprovides a method calledtryLock()which can check if lock is available or not without blocking. This method returnfalseif lock is not...

That's all abouthow to lock a file before writing in Java. If you are not the exclusive writer on the file or you are working with a shared file then you should always lock the file before writing data into it. Failing to do may result in file corruption and data loss. You should ...
In this exploration of the Global Interpreter Lock, we will delve into the reasons behind its existence, its impact on Python multithreading, and the implications for developers seeking to harness the power of concurrent processing. Understanding the nuances of the GIL is essential for Python develo...
In this tutorial we will go over Lock(), UnLock(), ReentrantLock(), TryLock() and how it's different from Synchronized Block in Java. If you have
Leveraging atomic operations in multithreading Let's now see how atomic operations are used. Consider incrementing a simple variable, a task that is not atomic by nature as it is made of three different steps — read the value, increment it, store the new value back. Traditionally, you would...
