public class Main {
  public static void main(String[] args) throws IOException {

    int[] buf = { 65, 66, 67, 68, 69, 70, 71 };

    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    DataOutputStream dos = new DataOutputStream(baos);

    for (int i : buf) {
      dos.write(i);
    }

    dos.flush();

    for (byte b : baos.toByteArray()) {
      char c = (char) b;
      System.out.print(c);
