What is Java NIO and how does it differ from traditional I/O?

Java NIO (New Input/Output) is a more modern approach to file handling in Java, offering non-blocking I/O operations. Unlike traditional I/O, which is blocking and uses streams, NIO uses channels and buffers, allowing for more efficient data handling.

Can you explain what channels and buffers are in Java NIO?

Sure! In Java NIO, a channel is a medium through which data flows, while a buffer is a container for data. Channels can read from and write to buffers, enabling efficient data transfer.

What are the advantages of using Java NIO over traditional I/O?

The main advantages of Java NIO include non-blocking I/O, improved performance with large data sets, and the ability to handle multiple connections simultaneously using selectors.

Are there any specific use cases where Java NIO is preferred?

Yes, Java NIO is preferred in scenarios like high-performance servers, real-time applications, and when dealing with large files or multiple network connections.
