Good Question

Answer 3

For ease of use - Scanner wins.. For speed- BufferedReader

Answer 4

basically scanner class takes input in form of tokens and buffered reader reads the input whole as a stream..
here token is a series of characters which ends with a delimiter either whitespace end of file or null.. so when u ask user to input data, the data is rendered by every token and waits for a delimiter.. so the exception may or may not occur ..
but in buffered reader the input is read in a stream of line then the exception may occur, if there is a whitespace or endoffile at the beginning itself.. so it needs to throw Exception..
