Write a program that reads four-digit integer as a string , such as 1998 and then displays it, one digit per line, like so:
1
9
9
8


Attempt:
Scanner keyboard2 = new Scanner (System.in);
String integer2= "Input a 4 digit number:";
System.out.println(integer2);

How do I make it read ? How do I go about this using string method ? I am lost. Thanks

 

bump, anyone :/

 

Use:

String lineOfText = 
  new BufferedReader(new InputStreamReader(System.in)).readLine();

Anyway, the problem is trivial if you coded it in Scala (a much better Java):

println(readLine mkString "\n")
