Part 4

File and Network I/O

This part presents reference information for Java classes that work with read and write files and work with data sent over a network. This includes classes that get input or display output via a console, which Java considers to be a type of file. It also includes classes for reading and writing files, working with directories and file paths, and sending and receiving data over a network.

Many of the classes described in this part involve the use of a Java I/O concept called streams. For general information about streams, see Streams (Overview).
