8. Java I/O and NIO (New I/O)

Java provides two major APIs for handling Input and Output operations: Standard I/O (java.io) and New I/O (java.nio). The former is stream-based while the latter, introduced in Java 1.4, improves performance with a buffer and channel-based model. Key differences include non-blocking I/O capabilities in NIO, which enhance scalability and concurrency, making it more suited for applications requiring high performance like network programming and management of large files.
