I'm working on getting switch and if statements down and I came up with this.  It works well and I don't have any problems with it running properly.  I was wondering if I could get some feedback on how I put it together.  If there are things I am doing wrong or could do better, I'm very open to suggestions!public static void main(String[] args) {    double edge = 0;    Scanner sc = new Scanner(System.in);    System.out.println(Enter the name of your Casino.);    String casino = sc.nextLine();    System.out.println(How many decks?
