Question

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.

Explanation / Answer

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