Java I/O can handle both byte and character streams.
Recall if there are separate classes for handling text and binary data.
In a multi-threaded application, how would you implement file reading using Java NIO while ensuring non-blocking I/O?
Think about how channels connect buffers and use selectors for efficient I/O.
