What is the purpose of atomic variables in Java?
Think about what happens when threads compete for a variable.
Name one class that is used as an atomic variable.
These classes provide atomic access to their respective data types.
What does AtomicInteger allow you to do?
Consider the main feature of atomic types.
True or False: AtomicBoolean can be used as a thread-safe flag.
Think about whether boolean states can be accessed safely in concurrent scenarios.
Given a situation where multiple threads access a shared resource, design a solution using AtomicBoolean to manage a running state effectively.
Draw upon your understanding of how AtomicBoolean can be changed safely.
Write code that demonstrates incrementing an AtomicLong in a multi-threaded environment while tracking how many times it has been incremented.
Utilize the incrementAndGet() method and control the number of threads involved.
