Vector with bytes to byte[ ]

Question

I have a Vector with bytes as it elements:
Vector _buffer = new Vector();
byte a = 120;
byte b = 67;
byte c = 98;
_buffer.addElement(a);
_buffer.addElement(b);
_buffer.addElement(c);And I want to read it our into a byte[ ], so it is more easy to, for example, make a string of it. So I want to do this:
byte[] b = (byte[]) _buffer.toArray(new byte[0]);But this isn't working, probably because byte is a primitive, and the function Vector: public <T> T[] toArray(T[] a) works on classes (I am not sure about this...?)
The following is working:
Vector _buffer = new Vector();
Byte a = new Byte(120);
Byte b = new Byte(67);
Byte c = new Byte(98);
_buffer.addElement(a);
_buffer.addElement(b);
_buffer.addElement(c);
Byte[] b = (Byte[]) _buffer.toArray(new Byte[0]);But this isn't what I want, because even now I can't make a byte[] out of the Byte[]. Is there an easy way (loops off course, but maybe a more elegant way) to bridge this gap between primitives and classes?
Thanks in Advance

You're reading from the stream and adding the bytes to a Vector<Byte>, right? Instead of storing them in a Vector<Byte>, write them to the ByteArrayOutputStream instead. Then you can call toByteArray() to get a byte[].
EDIT: I should've limited my quote in reply #5 to this part:
I need to have a dynamical created array. Because the order of the List is important I thought I would need to use a Vector object.
