Convert object to byte array

 / Published in: Java
 

From time to time, coders must convert an object to a stream of bytes. The following method accomplishes this task.

Expand | Embed | Plain Text 
  1. public static byte[] convertToByteArray(Object obj) throws IOException
  2.   {
  3.     ObjectOutputStream os = null;
  4.  
  5.     ByteArrayOutputStream byteStream = new ByteArrayOutputStream(5000);
  6.     os = new ObjectOutputStream(new BufferedOutputStream(byteStream));
  7.     os.flush();
  8.     os.writeObject(obj);
  9.     os.flush();
  10.     byte[] sendBuf = byteStream.toByteArray();
  11.     os.close();
  12.     return sendBuf;
  13.   }
