What are some concurrency tools available in C++ and Java?

In C++, you have tools like std::thread, std::mutex, and std::async. In Java, you can use the Executor framework, synchronized blocks, and the java.util.concurrent package.

Can you explain how std::thread works in C++?

Sure! std::thread allows you to create a new thread of execution. You can pass a function or a callable object to it, and it runs concurrently with the main thread.

What about the Executor framework in Java?

The Executor framework in Java provides a high-level API for managing threads. It allows you to create thread pools and manage task execution without dealing with thread lifecycle directly.

Are there any best practices for using these tools?

Yes, always ensure proper synchronization to avoid race conditions, and prefer using higher-level abstractions like futures and executors when possible.
