| 11. 16. 1. OutputStreamWriter |
|
|
- An OutputStreamWriter is a bridge from character streams to byte streams.
- Characters written to an OutputStreamWriter are encoded into bytes using a specified character set.
|
The OutputStreamWriter class has four constructors: |
|
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)
|
|
- The first constructor creates an instance that uses the default encoding.
- The others allow you to pass the encoding.
- The OutputStreamWriter class adds the getEncoding() to return the encoding in string.
- import java.io.File;
|
|
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStreamWriter;
public class MainClass {
public static void main(String[] args) {
try {
char[] chars = new char[2];
chars[0] = '\u4F60';
chars[1] = '\u597D';
String encoding = "GB18030";
File textFile = new File("C:\\temp\\myFile.txt");
OutputStreamWriter writer = new OutputStreamWriter(
new FileOutputStream(textFile), encoding);
writer.write(chars);
writer.close();
} catch (IOException e) {
System.out.println(e.toString());
}
}
}
