Question

1)If this is my code how can I make sure that if the user type lowercase letter I can convert it to uppercase letter?

private static int get_Menu_Choice() {

   System.out.print("\nCommand ? ");

   return in.next().charAt(0);

   }

2) How can I tell the user to print a sequence of integers separate by one space( he can't do more than one space or type something that its not integer. The sequence will go to a binary search Tree. I already coded the insert method.
