[Java] Cannot find symbol

[valerio65]

Ripeto, mi da errore sulla classe Scanner, già c'è scritto sopra!! Quindi:

C:\Users\Valerio\Desktop\Nuova cartella>javac Last.java
Last.java:8: error: cannot find symbol
                Scanner input = new Scanner(System.in);
                ^
  symbol:   class Scanner
  location: class Last
Last.java:8: error: cannot find symbol
                Scanner input = new Scanner(System.in);
                                    ^
  symbol:   class Scanner
  location: class Last
2 errors
