Simple input/output question

[zeidhaddadin]

I have got this code, but its not working in my computer, I'm using Textpad 4 for compiling:

import java.util.Scanner
public class Addition
{
     public static void main(String args[])
     {
          Scanner input = new Scanner(System.in);
          int a,b,sum;
          System.out.println("Enter the first integer: ");
          a = input.nextInt();
          System.out.println("Enter the second integer: ");
          b = input.nextInt();
          sum = a + b;
          Sytem.out.printf("Answer is: %d",sum);
      }
}

And the compiling error is:

C:\Documents and Settings\Computer\My Documents\My Homeworks\Java\Addition.java:1: cannot resolve symbol
symbol : class Scanner
location: package util
import java.util.Scanner;
^
C:\Documents and Settings\Computer\My Documents\My Homeworks\Java\Addition.java:6: cannot resolve symbol
