Lesson 13 - Multithreading in Java - Atomicity, Synchronized collections
In the previous lesson, Multithreading in Java - CompletableFuture, we talked about
CompletableFuture. Today's lesson will complete the course. We're
going to look at atomic variables and synchronized collections.
Atomic variables
At the beginning, we should explain what atomicity is.
It's a mechanism allowing us to access a variable, read its contents, and possibly modify it without using locks or other synchronization primitives.
In Java, we have atomic wrappers for all of the following data types:
Boolean, Integer, Long and other objects.
These are the classes:
AtomicBoolean- The wrapper for theBooleandata type.AtomicInteger- The wrapper for theIntegerdata type.AtomicLong- The wrapper for theLongdata type.AtomicReference- The wrapper for any other object.
We'll mention when to use these classes in a moment.
There are also atomic
