public class Main {

   public static void main(String[] args) {

      String s = "from java2s.com!";

      try {

         OutputStream os = new FileOutputStream("test.txt");
         OutputStreamWriter writer = new OutputStreamWriter(os,java.nio.charset.StandardCharsets.UTF_8);

         FileInputStream in = new FileInputStream("test.txt");

         writer.write(s, 0, 5);

         writer.flush();

         for (int i = 0; i < 5; i++) {
            System.out.print((char) in.read());
         }
         writer.close();
         in.close();
