    public static void main(String[] args) throws Exception {
     byte[] b_arr = {
      100,   101,   102,   103  };  ByteArrayOutputStream BAOS = null;  try {
      // Instantiates ByteArrayOutputStream   BAOS = new ByteArrayOutputStream();   // By using close() method isto   // close the ByteArrayOutputStream    BAOS.close();   // By using write() method is to   // write b_arr to the BAOS   BAOS.write(b_arr);   // By using toString() method is    // to represent the b_arr as a string   System.out.print("BAOS.write(b_arr): " + BAOS.toString());  } catch (Exception ex) {
      System.out.println(ex.toString());  } finally {
