Object to byte [] and byte [] to Object

Question

Hi,
I am quite new to java and need some help. My question is how can I convert an Object to byte [] and convert back from byte [] to Object.
I was thinking of something like:
From object to byte []
byte [] object_byte=object.toString().getBytes();
When I try to do:
String obj_string=object_byte.toString();
But obj_string is not even equal to object.toString().
Any suggestions?
Thanks

// byte[] to Object
byte[] b = new byte[]{1};
Object o = (new ObjectInputStream(new ByteArrayInputStream(b))).readObject();
// Object to byte[]
Object o = new Object();
ByteArrayOutputStream byteStream = new ByteArrayOutputStream();    
ObjectOutputStream objStream = new ObjectOutputStream(byteStream);       
objStream.writeObject(o);  
byte[] b = byteStream.toByteArray();
