@Youngistan is plain c++ to read every line from user input and store it into a string. — Luiggi Mendoza, Mar 02 '14 at 17:37

This is just part of the code. Where's the `while` loop? – Luiggi Mendoza Mar 02 '14 at 17:38
you don't need while loop. you can do your action with this. to finish taking input you can set a flag. – LynAs Mar 02 '14 at 17:42

Scanner scanner = new Scanner(System.in);
boolean flag = true;
while(flag)
{
   String str = scanner.nextLine();

   // Add any condition to set flag = false to exit from while loop
}

Kinda. Another way can be `String str = null; while ((str = scanner.nextLine() != null) { ... }`. – Luiggi Mendoza Mar 02 '14 at 18:07
yes,to exist the loop we need to write break inside it – Kick Mar 02 '14 at 18:11
