How to add a code in Code Playground that uses a Scanner?

Question

In my code I have:

//public class Main {
private static Scanner scanner = new Scanner(System.in);

I created a game that requires multiple input by users. How can I add this code to the playground so it works properly?

at Program.main(Program.java:24)
