Can you explain what hot streams are and where they are used?

Hot Threads are threads that actively utilize CPU time, often causing system load.

In the context of Android, hot threads usually refer to threads that perform long or resource-intensive operations, such as data processing, network requests, or complex calculations.

Applications of hot threads:

• Background processing: executing tasks that should not block the UI thread.
• Performance optimization: distributing load among threads to improve app responsiveness.

It is important to manage hot threads to avoid overloading the device and causing interface freezes. Android provides tools such as AsyncTask (deprecated), HandlerThread, ExecutorService, or modern Coroutines.

Example of using ExecutorService for hot threads:

ExecutorService executor = Executors.newFixedThreadPool(2);
executor.submit(() -> {
    // Long operation
    performHeavyTask();
});

Thus, hot threads are actively working threads used to perform heavy tasks without blocking the main UI thread.
