File I/O in Java with NIO: Efficient Techniques for File Handling

Java’s NIO (New Input/Output) provides more efficient file handling than traditional I/O by using buffers and channels. NIO supports non-blocking operations, improving performance when dealing with large files. The `Files` class in NIO simplifies file operations like reading and writing.

Here’s an example of reading a file using NIO:

Path path = Paths.get("example.txt");
List lines = Files.readAllLines(path);
lines.forEach(System.out::println);

NIO also supports asynchronous file operations, further improving efficiency in I/O-bound applications. Mastering NIO is essential for handling large datasets or real-time file processing efficiently.
