how to interrupt a scanner.nextline() call

Question

There are many threads on SO about interrupting reading the system.in but what I am looking for here is some kind of advice as to how to best code what I am trying to achieve.

Answer 1

Why not just poll with System.in.available() if there are bytes to read? It is non-blocking: one can do the call to Scanner.nextLine(), which is blocking, when sure it works and does not block.
