Question
Create a class called vehicle that has the manufacturer's name (type string), number of cylinders in the engine (type int), and owner (type person given next) Then, create a class called Truck that is derived from vehicle and has the following additional properties: the load capacity in tons (type double since it may contain a fractional part) and towing capacity in pounds (type int) Be sure your class has a reasonable complement of constructors, accessor and mutator methods, and suitably defined equals and to string methods. Write a program to test all your methods. The definition of the class Person follows. Completing the definitions of the methods is part of this programming project. public class Person { public Person() { } public Person (String theName) { } public Person (Person the Object) { } public string getName () { } public void setName { } (String theName)() { } public String tostring public boolean equals object other) { } }Explanation / Answer
Hi, Please find my implementation of Truck and Vehicle class.
######## Vehicle.java ########
public class Vehicle {
// instance variables
private String manufacturerName;
private int numCylinder;
private Person owner;
public Vehicle(String maString, int n, Person person){
manufacturerName= maString;
numCylinder = n;
owner = new Person(person);
}
public String getManufacturerName() {
return manufacturerName;
}
public void setManufacturerName(String manufacturerName) {
this.manufacturerName = manufacturerName;
}
public int getNumCylinder() {
return numCylinder;
}
public void setNumCylinder(int numCylinder) {
this.numCylinder = numCylinder;
}
public Person getOwner() {
return owner;
}
public void setOwner(Person owner) {
this.owner = owner;
}
@Override
public String toString() {
return "Manufaturer Name: "+manufacturerName+" "+
"Number of Cylinder: "+numCylinder+" "+
"Owner: "+owner.toString();
}
@Override
public boolean equals(Object obj) {
if(obj instanceof Vehicle){
Vehicle v = (Vehicle)obj;
if(manufacturerName.equals(v.manufacturerName) &&
numCylinder == v.numCylinder &&
owner.equals(v.owner))
return true;
}
return false;
}
}
######### Truck.java ##########
public class Truck extends Vehicle{
private double loadCapacity;
private int towingCApacity;
public Truck(String maString, int n, Person person, double load, int tow){
super(maString, n, person);
loadCapacity = load;
towingCApacity = tow;
}
public double getLoadCapacity() {
return loadCapacity;
}
public void setLoadCapacity(double loadCapacity) {
this.loadCapacity = loadCapacity;
}
public int getTowingCApacity() {
return towingCApacity;
}
public void setTowingCApacity(int towingCApacity) {
this.towingCApacity = towingCApacity;
}
@Override
public boolean equals(Object obj) {
if(obj instanceof Truck){
Truck t = (Truck)obj;
if(super.equals(t) && loadCapacity == t.loadCapacity &&
towingCApacity == t.towingCApacity)
return true;
}
return false;
}
@Override
public String toString() {
return super.toString()+" "+
"Load Capacity: "+loadCapacity+" "+
"Towing Cpacity: "+towingCApacity;
}
}
########## Test.java ##########
public class Test {
public static void main(String[] args) {
// creating Person Object
Person p = new Person("Pravesh Kumar");
// creating Truck Object
Truck t = new Truck("Tata Motora", 21, p, 45.32, 45);
System.out.println(t.toString());
}
}
/*
Sample run:
Manufaturer Name: Tata Motora
Number of Cylinder: 21
Owner: Name = Pravesh Kumar
Load Capacity: 45.32
Towing Cpacity: 45
*/
