OutputStream Class

Package: java.io

OutputStream is an abstract class from which all stream output classes are derived. The most commonly used output stream classes are BufferedOutputStream, FileOutput Stream, DataOutputStream, and PrintStream. You can use any of these classes whenever an OutputStream is called for.

Because you can’t create an instance of the OutputStream class, I won’t cover its constructors and methods here. For more information, see BufferedOutputStream, DataOutputStream, FileOutputStream, and PrintStream.

The OutputStream class is one of many Java I/O classes that use streams. For more information, see Streams (Overview).
