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.
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:
Long and other objects.
These are the classes:
AtomicBoolean- The wrapper for the
AtomicInteger- The wrapper for the
AtomicLong- The wrapper for the
AtomicReference- The wrapper for any other object.
We'll mention when to use these classes in a moment.
There are also atomic
