Use the following class definitions to answer questions 4 through 7

public class Vehicle
{
private int passengers;
private int fuelcap;
private int mpg;
Vehicle(int p, int f, int m)
{
passengers = p;
fuelcap = f;
mpg = m;
}
}
public class Truck extends Vehicle
{
private int cargocap;
private int test;
Truck(int p, int f, int m, int c)
{
super(p,f,m);
cargocap = c;
}
}
public class TruckDemo
{
public static void main(String[] args)
{
Truck semi = new Truck(2,200,7,44000);
Truck pickup = new Truck(3,28,15,2000);
