Making a program that calculates how many days you lived.

This is another code(below) from my CS Assignment. Here, I have to build a program that calculates how many days have you lived and how many hours you slept. I have seem to got the question but I get an error with Scanner sc = new Scanner(System.in);

Here is the code:

Code :

---

      import java.util.*;
   public class DaysLived {
      public static void main(String args [] ){
         Scanner sc = new Scanner(System.in);
         int by;
         int cy;
         int mb;
         int mc;
         int db;
         int dc;
         int sleep;
         int aliveday;
         aliveday = ((cy-by)*365)+((mc-mb)*30)+(dc-db);
         sleep = aliveday*8;
 
         System.out.println("What's the date today?");
         System.out.print ("Year: ");  
         cy = sc.nextInt ();
         System.out.print ("Month: ");
         mc = sc.nextInt ();
         System.out.print ("Day: ");
         dc = sc.nextInt ();
         System.out.println ("Great, when were you born?");
         System.out.print ("Year: ");  
         by = sc.nextInt ();
         System.out.print ("Month: ");
         mb = sc.nextInt ();
         System.out.print ("Day: ");
         db = sc.nextInt ();
         System.out.println ("You have lived " + aliveday + "and you have slept " + sleep + " hours.");
      }
   }

So, I am trying to get an input from the user.

What should I do?

Thanks in advance.

You should certainly copy and paste the full text of any errors you see.

Here are the errors I got:

variable aliveday may have not been initialized
variable sleep may have not been initialized
valu cannot be used ( on sleep = aliveday*8; )

And now if you look carefully over the errors description, you will hopefully, get the answers yourself. Do as your compiler is asking you to do.
