Poprawa kodu

Witam moglby mi ktos poprawic ten kod, poniewaz dzieje sie cos takiego:

Błąd 1:

Multiple markers at this line
    - The type new TimerCallback(){} must implement the inherited abstract method TimerCallback.success(Object)
    - The type new TimerCallback(){} must implement the inherited abstract method TimerCallback.error(Object)
    - Type safety: The expression of type new TimerCallback(){} needs unchecked conversion to conform to 
     TimerCallback<Player>

Błąd 2:

The method teleport(Location) in the type Entity is not applicable for the arguments (TimerUtil)
