Scanner vs InputStreamReader

Question

Does anyone happen to know if there is any difference with regards to performance between the two methods of reading input file below? Thanks.

A difference, and the principal, I guess, is that with the BufferedReader/InputStreamReader you can read the whole document character by character, if you want. With scanner this is no possible. It means that with the InputStreamReader you can have more control about the content of the document. ;)
