BufferedOutputStream Class

Package: java.io

The BufferedOutputStream class writes characters to an output stream, using a buffer for increased efficiency.

You won’t typically work directly with the BufferedOutputStream class; instead, you’ll use it to connect to a DataOutputStream, which has more advanced features for writing input data from binary files. As a result, this section shows only the constructor for the BufferedOutputStream class and not its methods. For more information, see DataOutputStream Class.

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

Constructor

Constructor	Description
BufferedIOutputStream (OutputStream out)	Creates a buffered output stream for the specified stream. Typically, you pass this constructor a FileOutput Stream object.

The following example shows how to create a Buffered OutputStream object that connects to a binary file:

File f;

FileOutputStream fstream;

BufferedOutputStream bstream;

f = new File(“myfile.bin”);

fstream = new FileOutputStream(f);

bstream = new BufferedOutputStream(fstream);
