Java vs C++ for Multithreading: Which is Better?

What are the main differences between Java and C++ when it comes to multithreading?

Java provides built-in support for multithreading with its Thread class and synchronized methods, while C++ offers more control through libraries like pthreads, but requires more manual management.

Which language is generally considered better for multithreading performance?

It depends on the use case. Java is often easier to use for multithreading due to its abstractions, while C++ can offer better performance in high-demand scenarios.

Can you explain how synchronization works in both languages?

In Java, synchronization is achieved using the synchronized keyword, which locks the object. In C++, synchronization can be done using mutexes from the standard library.

Are there any specific scenarios where one language outperforms the other?

Yes, for CPU-bound tasks, C++ may outperform Java due to lower overhead. However, for I/O-bound tasks, Java's built-in features can provide better performance.
