Why does InputStream#read() return an int and not a byte?
Because a
bytecan only hold -128 until 127, while it should return 0 until 255 (and -1 when there’s no byte left (i.e. EOF)). Even if it returnedbyte, there would be no room to represent EOF.A more interesting question is why it doesn’t return
short.
