java.util.scanner - Java Scanner - why do I get this error?

I'm not new to java, but I cannot figure out why I get this Scanner error. The code compiles fine, but I get the following runtime error

Enter item number: Exception in thread "main" java.util.InputMismatchException

at java.util.Scanner.next(Scanner.java:1461)

import java.util.Scanner;


public class TestInvoice {


    public static void main(String [] args)

    {
        /* create objects */
        Invoice item1 = new Invoice();
        Invoice item2 = new Invoice();
        Invoice item3 = new Invoice();

        /* get values */
        getValues(item1);
        getValues(item2);
        getValues(item3);


        /* print objects */
        System.out.println(item1.toString() + "\n");
        System.out.println(item2.toString() + "\n");
        System.out.println(item3.toString() + "\n");


    }

    private static void getValues(Invoice invoice)

    {        
        int number;
        String name;
        int quantity;
        double price;

        /* get values from user */
        Scanner scanner = new Scanner("System.in");

        System.out.print("Enter item number: ");

        number = scanner.nextInt();

        System.out.print("Enter item name: ");
        name = scanner.next();

        System.out.print("Enter quantity: ");
        quantity = scanner.nextInt();

        System.out.print("Enter item price: ");
        price = scanner.nextDouble();


        System.out.println();

        /* set the values */
        invoice.setItemNumber(number);
        invoice.setItemName(name);
        invoice.setItemQuantity(quantity);
        invoice.setItemPrice(price);

    }

}

Answer

Perhaps change

Scanner scanner = new Scanner("System.in");

to

Scanner scanner = new Scanner(System.in);
