Java Tutorial/File/OutputStreamWriter

OutputStreamWriter

1. An OutputStreamWriter is a bridge from character streams to byte streams.
2. Characters written to an OutputStreamWriter are encoded into bytes using a specified character set.

The OutputStreamWriter class has four constructors:

   <source lang="java">

public OutputStreamWriter (OutputStream out) public OutputStreamWriter (OutputStream out, java.nio.charset. Charset cs) public OutputStreamWriter (OutputStream out, java.nio.charset. CharsetEncoder enc) public OutputStreamWriter (OutputStream out, String encoding)</source>

Writing ISO Latin-1 Encoded Data

   <source lang="java">

import java.io.BufferedWriter; import java.io.FileOutputStream; import java.io.OutputStreamWriter; import java.io.Writer; public class Main {

 public static void main(String[] argv) throws Exception {
   Writer out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream("outfilename"),
       "8859_1"));
   out.write("asdf");
   out.close();
 }

}</source>

Writing UTF-8 Encoded Data

   <source lang="java">

import java.io.BufferedWriter; import java.io.FileOutputStream; import java.io.OutputStreamWriter; import java.io.Writer; public class Main {

 public static void main(String[] argv) throws Exception {
   Writer out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream("outfilename"),
       "UTF8"));
   out.write("asdf");
   out.close();
 }

}</source>
