er der nogen der kan se fejlen her?

Dette giver fejl:

class FuelUse {
   
    FuelUse() {
       
        int UseMoreRoad = 15;
        int NormalRoad = 8;
        int Distance = 40;
       
        int IaltNormal,IaltRough,RoughRoad,RoughRoadIalt;
       
        RoughRoad = NormalRoad * UseMoreRoad / 100;
        RoughRoadIalt = NormalRoad + RoughRoad;
        IaltNormal = Distance / NormalRoad * 100;
        IaltRough = Distance / RoughRoadIalt * 100;
       
        System.out.println(\"For normal road\" + IaltNormal);
        System.out.println(\"For rough road\" + IaltRough);
       
    }
    public static void main (String[] args) {
    new FuelUse ();
  }
}

Den siger:
java.lang.NoClassDefFoundError: fuel
Exception in thread \"main\"
