Write a class definition for an abstract class , Vehicle, that contains: a double instance variable , maxSpeed a protected double instance variable , currentSpeed a constructor accepting a double used to initialize the maxSpeed instance variable an abstract method , accelerate, that accepts no parameters and returns nothing. a method getCurrentSpeed that returns the value of currentSpeed a method getMaxSpeed that returns the value of maxSpeed a method , pedalToTheMetal, that repeatedly calls accelerate until the speed of the vehicle is equal to maxSpeed. pedalToTheMetal returns nothing.

CHALLENGE:

Write a class definition for an abstract class , Vehicle, that contains:
a double instance variable , maxSpeed
a protected double instance variable , currentSpeed
a constructor accepting a double used to initialize the maxSpeed instance variable
an abstract method , accelerate, that accepts no parameters and returns nothing.
a method getCurrentSpeed that returns the value of currentSpeed
a method getMaxSpeed that returns the value of maxSpeed
a method , pedalToTheMetal, that repeatedly calls accelerate until the speed of the vehicle is equal to maxSpeed. pedalToTheMetal returns nothing.

SOLUTION:

public abstract class Vehicle {
    private double maxSpeed;
    protected double currentSpeed;
    public Vehicle(double x){
        maxSpeed = x;
    }
    public abstract void accelerate();
    public double getCurrentSpeed(){
        return currentSpeed;
    }
    public double getMaxSpeed() {
        return maxSpeed;
    }
    public void pedalToTheMetal(){
        while (currentSpeed < maxSpeed) { accelerate(); } 
    } 
}
