Can you give an example of a task where you independently solved multithreading problems?

In one of my projects, I needed to implement parallel processing of a large volume of data to speed up computations. I used the Java Concurrency API, specifically the ExecutorService class for managing thread pools.

Example solution:

import java.util.concurrent.*;

public class ParallelProcessor {
    private final ExecutorService executor = Executors.newFixedThreadPool(4);

    public void processTasks(List<Runnable> tasks) throws InterruptedException {
        for (Runnable task : tasks) {
            executor.submit(task);
        }
        executor.shutdown();
        executor.awaitTermination(1, TimeUnit.HOURS);
    }
}

This approach allowed for efficient load distribution and reduced processing time. I also considered synchronization of shared resources and avoided data races by using synchronized blocks and thread-safe collections where necessary.
