FileInputStream & Negative Bytes...

Is there a way to have a file input stream not return negative values? Currently I'm using one to read a file that starts with the bytes:
6F 61 FE
The integer output of these should be: 111, 97, 254 repectively. However, I'm getting: 111, 97, -2. Is there a method that reads unsigned bytes like in the ImageInputStream Class?

All bytes are signed in Java. You can convert a byte to its unsigned integer representation if you need to like this:
FileInputStream fis = ... byte bytes = new byte; fis.read(bytes); for (int i=0; i<100; ++i) System.out.println(bytes[i] & 0xFF);
