java.io.DataOutputStream.writeBytes()
Writes the low order 8-bit bytes from a String to this output stream. @param str the String containing the bytes to write to the OutputStream @throws IOException If an error occurs attempting to write to this DataOutputStream. @see DataInput#readFully(byte[]) @see DataInput#readFully(byte[],int,int)
