How can I synchronize collections in Java and C++?

How can I synchronize collections in Java and C++?

In Java, you can use Collections.synchronizedList() for lists or Collections.synchronizedMap() for maps. In C++, you might use mutexes with STL containers to ensure thread safety.

Can you give me an example of using synchronized collections in Java?

Sure! Here's a simple example:

List<String> synchronizedList = Collections.synchronizedList(new ArrayList<>());
// Now you can safely add elements in a multi-threaded environment.

What about C++? How do I use mutexes with STL?

In C++, you can use std::mutex to protect access to a vector:

std::vector<int> myVector;
std::mutex mtx;

void threadSafeAdd(int value) {
    std::lock_guard<std::mutex> lock(mtx);
    myVector.push_back(value);
}
