What is atomicboolean class in Java?

AtomicBoolean supports atomic operations on underlying boolean variable. It have get and set methods that work like reads and writes on volatile variables.
How do I update a Boolean variable atomically?
The AtomicBoolean class gives you a boolean value that you can update atomically. Use it when you have multiple threads accessing a boolean variable. The java.util.concurrent.atomic package overview gives you a good high-level description of what the classes in this package do and when to use them.
