Here is the finished Car class:

public class Car {
    int originalValue;
    int speed;int damage;
    
    Car(int value           ) {
        originalValue=value;
        speed=0;
        damage=0;
    }
    
    int getSpeed(){
      return speed;
    }

    void accelerate(int value){
      speed=speed+value;
    }

    void crash(){
      damage=damage+20*speed;
      speed=0;
    }

    int currentValue(){
      return originalValue-damage;
    }
}
