Examples of java.io.RandomAccessFile.writeBytes()

java.io.RandomAccessFile.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 #read(byte[]) @see #read(byte[],int,int) @see #readFully(byte[]) @see #readFully(byte[],int,int)

                        // write an extra empty line before next section.
                        aWriter.writeByte((int) '\n');
