Problem 3, page 662. I am trying to print out the results, but Im getting an error message. Here is my code. my professor said I need to call the overloaded constructor in parent class via super. i dont know what that means. can yiou help me out. I have 4 files, Person.java, Vehicle.java, truck.java, and truckdemo.java
Vehicle.java
public class Vehicle {
private String manufactureName;
private int cylinders;
private Person owner;
Vehicle(){
}
public Person getOwner(String p){
return new Person(p);
}
public Vehicle(String make, int v, Person owner1 ){
this.owner=owner1;
this.cylinders=v;
this.manufactureName=make;
}
public void setOwner(Person name){
name=owner;
}
public void setmanufactureName(String manufacture){
manufactureName=manufacture;
}
public void setCylinders(int type){
cylinders=type;
}
public Person getOwner(){
return owner;
}
public String getmanufacture(String m){
return this.manufactureName;
}
public int getCylinders(int v){
return this.cylinders;
}
public void writeOutput(){
System.out.println("Owner name: "+getOwner().getName());
System.out.println("Vehicle type: "+manufactureName);
System.out.println("V-"+cylinders);
}
public boolean equals(Vehicle SecondVehicle, Person owner){
return (super.equals(getOwner()) &&
(this.manufactureName.equals(SecondVehicle)) &&
(this.cylinders==SecondVehicle.cylinders));
}
}
Truck.java
public class Truck extends Vehicle{
private double loadCapacity;
private double towingCapacity;
public Truck(){
super();
loadCapacity=100.00;
towingCapacity=200.00;
}
public Truck(String owner1, String make, int v,
double capacity, double towing ){
super.getOwner(owner1);
super.getCylinders(v);
super.getmanufacture(make);
capacity=loadCapacity;
towing=towingCapacity;
}
public void setloadCapacity(double capacity){
loadCapacity=capacity;
}
public void settowingCapacity(double towing){
towingCapacity=towing;
}
public double getloadCapacity(){
return loadCapacity;
}
public double gettowingCapacity(){
return towingCapacity;
}
public boolean equals1(Truck OtherTruck, Vehicle SecondVehicle){
return (super.equals(SecondVehicle)&& (this.loadCapacity==OtherTruck.loadCapacity) &&
(this.towingCapacity==OtherTruck.towingCapacity) &&
(this.getOwner().equals(OtherTruck)));
}
public void writeOutput1(){
super.writeOutput();
System.out.println("Truck load capacity: "+loadCapacity);
System.out.println("Truck towing capacity: "+towingCapacity);
}
}
TruckDemo.java
public class TruckDemo {
public static void main(String[] args) {
// TODO Auto-generated method stub
//Person owner = new Person("Scott");
//Vehicle first = new Vehicle("Mazda", 4, "Scott");
//owner.writeOutput();
//first.writeOutput();
System.out.println();
//String owner1, String make, int v,
//double capacity, double towing
Truck attributes = new Truck("Scott", "Mazda", 4, 400, 500);
//attributes.writeOutput();
attributes.writeOutput1();
System.out.println();
Truck second = new Truck("Scott", "Mazda", 4,400,500);
//Person name = new Person("Cliff");
second.writeOutput1();
System.out.println(" Does first truck attributes equal "
+ "second truck attributes? "+attributes.equals(second));
}
}
