Getting Input From User

[Remi Forax]

In Java, you can use the Console:
  System.console().readLine("")
with the caveat that System.console() [1] can return null if no terminal is attached to the process.

Otherwise you can use a Scanner:
  Scanner scanner = new Scanner(System.in);
  scanner.nextLine()

or a BufferedReader:
  BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
  reader.readLine()
or
  reader.lines() 
if you want a Stream of all lines.

cheers,
Rémi
