This is my program: import java.util.Scanner; public class Restaurant { public static void main(String[] args) { System.out.print("What is the age of guest: "); Scanner a = new Scanner(System.in); int b = a.nextInt(); if(b < 0) { System.out.print("Invalid age"); } else if(b < 12) { System.out.print("Discount: 20%"); } else { System.out.print("Discount: 0%"); } } }

I think it prints out: Well Done Your grade is C
