Class OutputStreamWriter
- Appendable, AutoCloseable, Closeable, Flushable
This class writes characters to an output stream that is byte oriented
It converts the chars that are written to bytes using an encoding layer,
which is specific to a particular encoding standard. The desired
encoding can either be specified by name, or if no encoding is specified,
the system default encoding will be used. The system default encoding
name is determined from the system property
file.encoding.
The only encodings that are guaranteed to be available are "8859_1"
(the Latin-1 character set) and "UTF8". Unfortunately, Java does not
provide a mechanism for listing the encodings that are supported in
a given implementation.
Here is a list of standard encoding names that may be available:
- 8859_1 (ISO-8859-1/Latin-1)
- 8859_2 (ISO-8859-2/Latin-2)
- 8859_3 (ISO-8859-3/Latin-3)
- 8859_4 (ISO-8859-4/Latin-4)
- 8859_5 (ISO-8859-5/Latin-5)
- 8859_6 (ISO-8859-6/Latin-6)
- 8859_7 (ISO-8859-7/Latin-7)
- 8859_8 (ISO-8859-8/Latin-8)
- 8859_9 (ISO-8859-9/Latin-9)
- ASCII (7-bit ASCII)
- UTF8 (UCS Transformation Format-8)

OutputStreamWriter
public OutputStreamWriter(OutputStream out)
This method initializes a new instance of OutputStreamWriter
to write to the specified stream using the default encoding.
out - The OutputStream to write to
OutputStreamWriter
public OutputStreamWriter(OutputStream out,
String encoding_scheme)
throws UnsupportedEncodingException This method initializes a new instance of OutputStreamWriter
to write to the specified stream using a caller supplied character
encoding scheme. Note that due to a deficiency in the Java language
design, there is no way to determine which encodings are supported.
out - The OutputStream to write toencoding_scheme - The name of the encoding scheme to use for
character to byte translation
OutputStreamWriter
public OutputStreamWriter(OutputStream out,
Charset cs) This method initializes a new instance of OutputStreamWriter
to write to the specified stream using a given Charset.
out - The OutputStream to write tocs - The Charset of the encoding to use
OutputStreamWriter
public OutputStreamWriter(OutputStream out,
CharsetEncoder enc) This method initializes a new instance of OutputStreamWriter
to write to the specified stream using a given
CharsetEncoder.
out - The OutputStream to write toenc - The CharsetEncoder to encode the output with
getEncoding
public String getEncoding()
This method returns the name of the character encoding scheme currently
in use by this stream. If the stream has been closed, then this method
may return null.
write
public void write(char[] buf,
int offset,
int count)
throws IOException This method writes count characters from the specified
array to the output stream starting at position offset
into the array.
- write in interface Writer
buf - The array of character to write fromoffset - The offset into the array to start writing chars fromcount - The number of chars to write.
write
public void write(int ch)
throws IOException This method writes a single character to the output stream.
- write in interface Writer
ch - The char to write, passed as an int.
write
public void write(String str,
int offset,
int count)
throws IOException This method writes count bytes from the specified
String starting at position offset into the
String.
- write in interface Writer
str - The String to write chars fromoffset - The position in the String to start
writing chars fromcount - The number of chars to write
