What is a race condition and how do you prevent it?
A race condition occurs when multiple threads access shared mutable state concurrently and the outcome depends on timing. Prevent it with synchronization, locks, atomic classes, or immutable/thread-confined data.
Example
// Without synchronization, count++ isn't atomic AtomicInteger count = new AtomicInteger(0); count.incrementAndGet(); // thread-safe increment
