public class OutputStreamWriter
extends Writer
Write characters to an output stream, translating characters into bytes according to a specified character encoding. Each OutputStreamWriter incorporates its own CharToByteConverter, and is thus a bridge from character streams to byte streams.
The encoding used by an OutputStreamWriter may be specified by name, by providing a CharToByteConverter, or by accepting the default encoding, which is defined by the system property file.encoding.
Each invocation of a write() method causes the encoding converter to be invoked on the given character(s). The resulting bytes are accumulated in a buffer before being written to the underlying output stream. The size of this buffer may be specified, but by default it is large enough for most purposes. Note that the characters passed to the write() methods are not buffered. For top efficiency, consider wrapping an OutputStreamWriter within a BufferedWriter so as to avoid frequent converter invocations. For example,
Writer out = new BufferedWriter(new OutputStreamWriter(System.out));
