Can you explain the principle of atomic operations in programming?

Atomic operations are operations that are performed entirely or not at all, without intermediate states visible to other threads or processes. This guarantees data integrity during concurrent access.

Example: incrementing a counter in a multithreaded application. If the operation is not atomic, two threads might read the same value simultaneously and write the same result, losing the update.

In Android and Java, classes from the java.util.concurrent.atomic package are often used for atomic operations, for example, AtomicInteger:

AtomicInteger counter = new AtomicInteger(0);
counter.incrementAndGet(); // atomic increment

This helps avoid locks and ensures correct operation with shared data.
