Inspect the following three classes. Keeping good OOP practices (such as inheritance, encapsulation, interface segregation, etc,) in mind, remodel them (i.e., Create new classes -from these three classes- that follow OOP principles more closely) you can use getters/setters, as well :

public class FamilyCar

{

public String ownerName = "ABC"; public String brand; public int gasTankCapacity; public int mileage; public Int currentSpeed;

public void Accelerate(int speed) { ... } public void Decelerate (int speed) { ... } public void SetRoute (String from, String to) { ... } public void BlowHorn() { ... }

}

...................................................................................................................

public class SportCar

{

public String ownerName = "ABC"; public String brand; public int gasTankCapacity; public int mileage; public int currentSpeed;

public Int turboCapacity ;

public void Accelerate(int speed) { ... } public void Decelerate (int speed) { ... }

public void EngageTurbo { ... } public void SetRoute (String from, String to) { ... } public void BlowHorn() { ... }

}

...........................................................................................................

public class Bike

{

public String ownerName = "ABC"; public String brand; public int currentSpeed;

public void Accelerate(int speed) { ... } public void Decelerate (int speed) { ... } public void SetRoute (String from, String to) { ... } public void RingBell() { ... }

}
