import java.io.ByteArrayInputStream;
import java.io.DataInputStream;
import java.io.IOException;
import java.io.InputStream;

public class Main {
  public static void main(String[] args) throws IOException {
    byte[] buf = { 1, 2, 3, 4, 5 };

    InputStream is = new ByteArrayInputStream(buf);

    DataInputStream dis = new DataInputStream(is);

    while (dis.available() > 0) {
      byte b = dis.readByte();
      System.out.print(b);
    }

  }
}
