Use a PrintWriter to write two Chinese characters and read them back in Java
Description
The following code shows how to use a PrintWriter to write two Chinese characters and read them back.
An InputStreamReader reads bytes and translates them into characters using the specified character set.
InputStreamReader is ideal for reading from the output of an OutputStreamWriter or a PrintWriter.
Example
// ww w . j ava2s .co m
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
public class Main {
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");
PrintWriter writer = new PrintWriter(textFile,encoding);
writer.write(chars);
writer.close();
// read back
InputStreamReader reader = new InputStreamReader(new FileInputStream(textFile), encoding);
char[] chars2 = new char[2];
reader.read(chars2);
System.out.print(chars2[0]);
System.out.print(chars2[1]);
reader.close();
} catch (IOException e) {
System.out.println(e.toString());
}
}
}
The code above generates the following result.
