import java.io.IOException;
import java.nio.ByteBuffer;
import java.nio.channels.FileChannel;

public class MainClass {
  public static void main(String args[]) {
    FileOutputStream fileOutputStream;
    FileChannel fileChannel;
    ByteBuffer byteBuffer;

    try {
      fileOutputStream = new FileOutputStream("test.txt");
      fileChannel = fileOutputStream.getChannel();
      byteBuffer = ByteBuffer.allocateDirect(26);

      for (int i = 0; i < 26; i++)
        byteBuffer.put((byte) ('A' + i));
      byteBuffer.rewind();
      fileChannel.write(byteBuffer);
      fileChannel.close();
      fileOutputStream.close();
    } catch (IOException exc) {
      System.out.println(exc);
