What are some effective thread safety techniques in programming?

Thread safety techniques ensure that shared data is accessed by multiple threads without conflict. Common techniques include using locks, semaphores, and atomic operations.

Can you explain how locks work in thread safety?

Locks are mechanisms that prevent multiple threads from accessing a resource simultaneously. When a thread acquires a lock, other threads must wait until the lock is released.

What are the downsides of using locks?

While locks can prevent data corruption, they can also lead to issues like deadlocks, where two or more threads are waiting indefinitely for each other to release locks.

Are there alternatives to locks for ensuring thread safety?

Yes, alternatives include using lock-free data structures, read-write locks, and concurrent collections that manage access without traditional locking.
