Question

As part of a programming exercise I received the following:

“Simulator will receive orders from stdin in a simplified ascii format specified later in this document…”

“Input is received from stdin, and is in comma-separated ascii format. You may assume that the input will always be correctly formatted”

Example:

B,100322,5103,7500

This is all about the input mechnism. What i don’t understand is the stdin them mention – is that the usual console input by the user, file input etc. ?

Answer 1

Usual console, yes.

In Java, the standard streams are referred to by System.in (for stdin), System.out (for stdout), and System.err (for stderr).

See http://en.wikipedia.org/wiki/Standard_streams for further details
