class Vehicle {
   private int number;
   private String color;
   private double price;
   private double horsepower;

   Vehicle() {

   }

   public Vehicle(int aNumber) {
       super();

   }

   public Vehicle(int aNumber, String aColor, double aPrice, double aHorsepower) {
       super();
       number = aNumber;
       color = aColor;
       price = aPrice;
       horsepower = aHorsepower;
   }

   public int getNumber() {
       return number;
   }

   public void setNumber(int aNumber) {

   }

   public double getPrice() {
       return price;
   }

   public void setPrice(double aPrice) {
       price = aPrice;
   }

   public double getHorsepower() {
       return horsepower;
   }

   public void setHorsepower(double aHorsepower) {
       horsepower = aHorsepower;
   }

   public String toString()

   {

               + "\n color = " + color

               + "\n price = " + price

               + "\n horsePower = " + horsepower;
   }

   public void vehicleInformation() {
       System.out.println(this);
   }
}

public class VehicleTester

{

   public static void main(String[] args)
