This is your solution :
public class NewMain { public static void main(String args[]) throws ParseException { Scanner s = new Scanner(System.in); char yes; do { System.out.println("Hi"); yes = s.next().charAt(0); } while (yes == 'Y'); // if u enter 'Y' the it will continue } } To exit enter any thing other then 'Y'
