I had the same struggle and I this is what I used     public static void main String   args     Scanner scan   new Scanner System in   System out print  Please enter the string      String input   scan next    System out print  Please enter the required symbol      String symbol   scan next            char symbolChar   symbol charAt 0     This works just fine  The idea is to get from the string the only char in it
