Differences between FileInputStream FileReader

I saw these two examples in the following tutorial - http://download.oracle.com/javase/tutorial/essential/io/charstreams.html

FileReader/FileWriter


FileInputStream/FileOutputStream


One of the difference listed in the above is that both CopyBytes and CopyCharacters use an int variable to read to and write from. However, in CopyCharacters, the int variable holds a character value in its last 16 bits; in CopyBytes, the int variable holds a byte value in its last 8 bits. Can someone explain this difference please (i.e why 16bit on one and not the other. )

Thanks

Is it because java stores characters in 16bit UNICODE or is there any other specific reason?

FileInputStream to read the image data , such as raw byte stream.
Character stream to read, consider using FileReader.
