Is byte stream encodes byte to characters or only operates on bytes?

We have byte and character stream, If you read some examples from internet you can find that byte stream only operates on bytes and nothing more.

Byte to “Bit”array

A byte is the smallest numeric datatype java offers but yesterday I came in contact with bytestreams for the first time and at the beginning of every package a marker byte is send which gives further instructions on how to handle the package.

How to Convert Int to Unsigned Byte and Back

I need to convert a number into an unsigned byte. The number is always less than or equal to 255, and so it will fit in one byte. I also need to convert that byte back into that number. How would I do that in Java? I’ve tried several ways and none work. Here’s what I’m trying to do now:
