Enter and Output (IO) in Java are streams which might be used to learn and write information. An enter stream is a sequence of bytes that may be learn from. An output stream is a sequence of bytes that may be written to. IO streams are utilized in a wide range of purposes, reminiscent of studying from a file, writing to a database, or sending information over a community.

Buffered streams are extra environment friendly than unbuffered streams, as they retailer information in a buffer earlier than it’s learn or written. This will enhance efficiency, particularly for big information transfers.
