Considering this, what is an atomic operation in Java?
An atomic operation is an operation which is performed as a single unit of work without the possibility of interference from other operations. The Java language specification guarantees that reading or writing a variable is an atomic operation(unless the variable is of type long or double ).
Subsequently, question is, do you need to synchronize an atomic operation? Atomic actions cannot be interleaved, so they can be used without fear of thread interference. However, this does not eliminate all need to synchronize atomic actions, because memory consistency errors are still possible. This means that changes to a volatile variable are always visible to other threads.
Likewise, people ask, what is an atomic operation?
Atomic operations in concurrent programming are program operations that run completely independently of any other processes. Atomic operations are used in many modern operating systems and parallel processing systems.
What is AtomicInteger and when to use?
Among them, the AtomicInteger class is a wrapper class for an int value that allows it to be updated atomically. The class provides useful methods, some of which will be shown in the code snippet below. The most common use of the AtomicInteger is to handle a counter that is accessed by different threads simultaneously.
