What are some synchronization techniques in C++ and Java?

In C++, you can use mutexes, condition variables, and atomic operations. In Java, you have synchronized blocks, locks, and semaphores. Would you like to know more about a specific technique?

Can you explain how mutexes work in C++?

Sure! A mutex (mutual exclusion) is a synchronization primitive that prevents multiple threads from accessing a shared resource simultaneously. You lock the mutex before accessing the resource and unlock it afterward.

What about synchronized blocks in Java?

In Java, synchronized blocks allow you to control access to a block of code by a specific object. Only one thread can execute the synchronized block at a time for that object, ensuring thread safety.

Are there any performance considerations I should be aware of?

Yes, excessive locking can lead to contention and reduce performance. It's important to minimize the time a mutex is held and to avoid deadlocks by following best practices.
