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.

Java provides two major APIs for handling Input and Output operations: Standard I/O (java.io) and New I/O (java.nio).

Java I/O is stream-based and suitable for file and stream data operations.
The introduction of NIO offers significant performance improvements through non-blocking I/O and efficient file handling.
Understanding both I/O models equips developers to choose the appropriate API for specific application requirements.
Used to handle raw binary data, allowing input and output operations for various data types like images and audio.
Specifically designed for handling character data and ensuring correct encoding/decoding during input and output operations.
A container for data used in NIO that allows for efficient reading from and writing to a channel.
A communication link in NIO between I/O devices and buffers, enabling faster, non-blocking I/O operations.
Facilitates non-blocking I/O operations, allowing a single thread to manage multiple channels, essential for server applications.
Represents a file or directory path in the file system used in NIO for file management.
Utility class in NIO that provides methods for file manipulation tasks like copying, moving, and reading files.
