What are some real-world examples of thread safety?

Thread safety ensures that shared data is accessed by multiple threads without conflict. Examples include: 1. Java's synchronized methods, 2. C#'s lock statement, and 3. Python's threading module with locks.

Can you explain how Java's synchronized methods work?

Sure! In Java, synchronized methods prevent multiple threads from executing a method simultaneously on the same object, ensuring that only one thread can access the method at a time.

What happens if a thread tries to access a synchronized method?

If a thread attempts to access a synchronized method while another thread is already executing it, the second thread will be blocked until the first thread completes its execution.

Are there any performance drawbacks to using thread safety?

Yes, using thread safety mechanisms can introduce overhead and reduce performance due to context switching and potential bottlenecks, especially in highly concurrent applications.
