if you’re new to Java and programming, do ensure that you’re using a step-by-step tutorial. Sketch App is currently the only Java tutorial listed on replit

I can see that there’d be a blocking loop, but what do you expect your program to do?

If you want to print the variable n, you shouldn’t be putting " around it.
And to print a variable within a string, use out.printf:

System.out.printf("your order is %s", n);

Looks like you’ve since changed the code you’re using and then stopped in the middle? resturant

after int read also end of line (CR)

      n = scan.nextLine();
      q = scan.nextInt();
      scan.nextLine(); //CR
