DAY 17:
the Internet
Java was developed initially as a language that would control a network of
interactive consumer devices. Connecting machines was one of the main
purposes of the language when it was designed, and that remains true
today.
The
java.net
package makes it possible to communicate over a net-
work, providing cross-platform abstractions to make connections, transfer
files using common web protocols, and create sockets.
Used in conjunction with input and output streams, reading and writing
files over the network becomes as easy as reading or writing files on
disk.
The
java.nio
package expands Java's input and output classes.
Today, you write networking Java programs, creating applications that load
a document over the Web, mimic a popular Internet service, and serve
information to clients.
