What information does the ThreadPoolExecutor object provide after completing its task?

The ThreadPoolExecutor object in Java, after task completion, provides information about the thread pool's state and completed tasks. The main data that can be obtained:

• Number of active threads (getActiveCount()) — how many threads are currently busy.
• Total number of completed tasks (getCompletedTaskCount()).
• Total number of tasks submitted (getTaskCount()).
• Pool size (getPoolSize()).
• Pool status (isShutdown(), isTerminated()).

These methods allow monitoring and managing the thread pool's state after task execution, which is important for optimization and debugging multithreaded applications.
