Overview

NIO (Non-blocking IO) was introduced in Java 4 and enhanced with new File operations as NIO.2 in Java 7. The major improvement introduced by NIO was to allow non-blocking, block-oriented I/O operations from Java programs. Somewhat unrelated, NIO offers new features such as file locking and characters sets, and NIO.2 comes with a new file system access API.
