At times when more than one thread try to access a shared resource, we need to ensure that resource will be used by only one thread at a time. The process by which this is achieved is called synchronization.

Synchronization in Java is the capability to control the access of multiple threads to any shared resource. Java Synchronization is better option where we want to allow only one thread to access the shared resource. Why use Synchronization? The synchronization is mainly used to To prevent thread i...
In this article, multiple types of synchronization, locking and thread-safety techniques in Java and Kotlin are explained through interactive examples. Photo by Tomas Sobek on Unsplash What is Synchronization? In a multi-threaded world, we need to access shared objects across threads, and If we ...
As soon as we start using concurrent threads, we need to think about various issues that fall under the broad description of thread safety. Generally, we need to take steps to make sure that different threads don't interact in negative ways: ...
I'm self-learning Java and I want to understand multithreading. I createdMyThreadclass with a job to perform a loop until a condition is true and then print information about it. It contains static fieldleftwhich is incremented in a constructor and decremented when a job is done. ClassFlag...
Java - Thread Synchronization - When we start two or more threads within a program, there may be a situation when multiple threads try to access the same resource and finally they can produce unforeseen result due to concurrency issues. For example, if m
In Java, two synchronization strategies are used to prevent thread interference and memory consistency errors: Synchronized Method: Includes the synchronized keyword in its declaration. When a thread invokes a synchronized method, synchronized method automatically acquires the intrinsic lock for that method...
