Converting Binary String into byte and not char while writing to file

I want to write the file as byte only and not the character.

String binaryString = "10110101"

I am using 

byte mybyte  = Byte.parseByte(binaryString,2);

I want to write this converted byte into the file as a byte and not the character.

I am using :

FileOutputStream fos1 = new FileOutputStream(new File("output"));
fos.write(mybyte);

But after write, when I see the files the byte is actually written as the characters.

Is I am doing something wrong in conversion ? How to make it write as byte and not char ?

Edit:

Like for the String 101101010111001011111000 (taking 8 bits at a time and then writing to the file) : it is converted to "Z9|".

You actually write the binary data 10110101 to the file, but when you open that file in a text editor it will be displayed as a character.

If you want to write text that represent the given number (e.g. in decimal form), use a Writer:

FileOutputStream fos1 = new FileOutputStream(new File("output"));
OutputStreamWriter w = new OutputStreamWriter(fos1, StandardCharsets.UTF_8);
w.write(""+mybyte); // ""+mybyte creates a string with the decimal representation of mybyte
