The volatile keyword in Java is used in the context of multithreading to indicate that a variable’s value will be modified by different threads. Declaring a variable as volatile ensures that changes to that variable are immediately visible to all threads, which helps to avoid memory consistency errors. Here are the key points about the […]

In Java, atomic variables provide a way to perform thread-safe operations on variables without needing to use explicit synchronization. They ensure that operations on the variable are executed atomically, meaning that they are indivisible and cannot be interrupted by other threads halfway through. Atomic Variable Classes in Java Atomic variables in Java are part of

Java provides several utilities and collections that help in writing thread-safe code. These utilities and collections are part of the java.util.concurrent package. Thread Safety Utilities Locks and Synchronizers ReentrantLock: Provides a re-entrant mutual exclusion lock with the same basic behaviour and semantics as the implicit monitor lock accessed using synchronized methods and statements but with

In Java, a shared object is typically an object that can be accessed by multiple threads simultaneously. To handle such situations, you often need to synchronize access to ensure thread safety. Shared Objects in Java  A shared object refers to an instance of a class that can be accessed and modified by multiple threads concurrently.

Java provides several utilities for managing synchronization in collections to ensure thread safety when multiple threads are accessing or modifying them concurrently. Two primary ways to achieve this are using explicit locking with ReentrantLock and using synchronized collections from the java.util.Collections class. Locking with ReentrantLock ReentrantLock provides explicit control over locking, offering flexibility and capabilities

Thread synchronization in Java is essential to ensure that multiple threads can safely access shared resources without causing data corruption or inconsistency. Java provides several mechanisms for thread synchronization: Synchronized Methods and Blocks .Reentrant Locks Volatile Keyword Atomic Variables Wait/Notify Mechanism Semaphore CountDownLatch Synchronized Methods and Blocks Using the synchronized keyword, you can synchronize methods

In Java, critical sections and mutual exclusion are essential concepts for handling concurrent programming and ensuring thread safety. A critical section is a part of the code that accesses a shared resource and must not be executed by more than one thread at a time. Mutual exclusion ensures that only one thread accesses the critical

A race condition occurs when two or more threads access shared data at the same time, and the final result depends on the timing of their execution.If one thread’s operations overlap with another thread’s operations without proper synchronization, unexpected and inconsistent results can occur. A race condition happens when the program’s behavior changes based on
