No. You use ByteArrayInputStream when you have an array of bytes, and you want to read from the array as if it were a file. If you just want to read arrays of bytes from the socket, do this:

InputStream stream = socket.getInputStream();
byte[] data = new byte[100];
int count = stream.read(data);

The variable count will contain the number of bytes actually read, and the data will of course be in the array data.
