Java Code is Not Working in Eclipse?

Hello Everyone, I am studying Computer Science at ITM University and I’ve come across a problem. Initially, our teacher cannot help me due to the AQA Guidelines. So I am sharing the coding problem here.

class Price {
    public static void main(String args[])  {
        Scanner keyboard = new Scanner (System.in);
        int day;
        double price = 0.00;



    System.out.print("How many days would you like to reserve the game?:  ");
    day = keyboard.nextInt();

    if (day >= 4 && day <= 5) {
        price = 5.55;

        System.out.print("You have chosen to reserve the game for " + day + " days! ");

        System.out.println("Please pay £" + price + ". " + " Enjoy your game!");
        }

    if (day == 3) {
        price = 3.45;

        System.out.print("You have chosen to reserve the game for " + day + " days! ");

        System.out.println("Please pay £" + price + ". " + " Enjoy your game!");
        }

    if (day >= 1 && day <= 2) {
        price = 2.75;

        System.out.print("You have chosen to reserve the game for " + day + " days! ");

        System.out.println("Please pay £" + price + ". " + " Enjoy your game!");

    }
    if (day > 5 || day <= 0) {
        System.out.println("Invalid Number - Days of Reservation Are 1-5 Only. Please Try Again.");
    }

    keyboard.close();
}
}

My problem is that this code works on Online Compilers such as on Interviewbit Java Compiler with no worries yet Eclipse reads the following error:

"Exception in thread "main" java.lang.Error: Unresolved compilation problems:

Scanner cannot be resolved to a type

Scanner cannot be resolved to a type

at Price.main(Price.java:3)"

Can anyone suggest me or Provide some solution?

Thanks :slight_smile:
