Question

Note: Anwer this as mention in the Question and do it urgently ( just simple uml of dry run kindly please fo fast)

Q1: Test the follow code step by step from the main. Add enough detail to justify the use of OOP concepts in these examples. Also draw the UML diagram using all given code. Finally show the output of this code [Note: Only output will not acceptable]

Code

with commnetns

Person class

public class Person {
//instace varibale type String that stores the name of Person
private String name;
//default constructor that set name to none
public Person()
{
name = "none";
}
//parameterize constructor that set the name as give in parameter
public Person(String theName)
{
name = theName;
}
//copy constructor that assing the name of theObject to the this name
public Person(Person theObject)
{
name = theObject.name;
}
//getter method for name
public String getName()
{
return name;
}
//setter method for name taht set the name
public void setName(String theName)
{
name = theName;
}
//toString method that return the name of person
public String toString()
{
return name;
}
//equals method that check this and other object are same or name
public boolean equals(Object other)
{
return name.equals(((Person)other).name);
}
}

Vehicle class

public class Vehicle {
//properteis of Vehicle
private String mf;//
private int cd;
private Person own;
//default constructor for Vehicle that sets default value
public Vehicle()
{
mf = "none";
cd = 1;
own = null;
}
//patametrize constructor
public Vehicle(String themf, int numcd, Person theown)
{
mf = themf;
cd = numcd;
own = new Person(theown);
}
//copy constructor
public Vehicle(Vehicle other)
{
mf = other.mf;
cd = other.cd;
own = new Person(other.own);
}
//setter method
public void setmf(String newmf)
{
mf = newmf;
}
public void setcd(int newNum)
{
cd = newNum;
}
public void setown(Person newown)
{
own = new Person(newown);
}
//getter methods
public String getmf()
{
return mf;
}
public int getcd()
{
return cd;
}
public Person getown()
{
return own;
}
//toString method that return the string with properties of vehicle
public String toString()
{
return mf + ", " + cd + " cd, owned by " + own;
}
//equals method that check fo equality of vehicle
public boolean equals(Vehicle other)
{
return mf.equals(other.mf) && cd == other.cd;
}
}

Truck class

public class Truck extends Vehicle{
//instance varibales of Vehicle
private double load;
public int capacity;
//default constructor
public Truck()
{
super();
load = 0;
capacity = 0;
}
//parameterize constructor
public Truck(String m, int c,Person p, double loads,int capc)
{
super(m, c, p);
load = loads;
capacity = capc;
}
//copy constructor
public Truck(Truck oth)
{
super(oth);
load = oth.load;
capacity = oth.capacity;
}
//set methods for propertise of vehicle
public void setload(double newLoad)
{
load = newLoad;
}
public void setcapacity(int newCaps)
{
capacity = newCaps;
}
//get methods for propertise of vehicle
public double getload()
{
return load;
}
public int getcapacity()
{
return capacity;
}
//tostring method
public String toString()
{
return super.toString() + ", " + load + " lbs load, " + capacity + " tow";
}
//equal for checking equality
public boolean equals(Truck oth)
{
return super.equals(oth) &&
load == oth.load &&
capacity == oth.capacity;
}
}

CompelteTest

public class CompleteTest {

public static void main(String[] args) {
//creates the two object of the class person with parameterize constructor
Person owner1 = new Person("Nathan Roy");
Person owner2 = new Person("Peter England");
//creater a vehicle object with parameterize constructor
Vehicle aCar = new Vehicle("Honda", 5, owner2);
//crates a object of Truck object wirh default constructor
Truck aTruck = new Truck();
//sets all the properties of Truck using setters methods
aTruck.setmf("Skoda");
aTruck.setcd(100);
aTruck.setown(owner1);
aTruck.setload(150.50);
aTruck.setcapacity(3200);
  
System.out.println("Truck Details: ");
System.out.println(aTruck.getmf());
System.out.println(aTruck.getcd());
System.out.println(aTruck.getown());
System.out.println(aTruck.getload());
System.out.println(aTruck.getcapacity());
System.out.println();
System.out.println("Details of Vehicle 1: ");
System.out.println(aCar);
System.out.println("Details of Vehicle 2: ");
System.out.println(aTruck);
}
  
}

Output

Truck Details:
Skoda
100
Nathan Roy
150.5
3200

Details of Vehicle 1:
Honda, 5 cd, owned by Peter England
Details of Vehicle 2:
Skoda, 100 cd, owned by Nathan Roy, 150.5 lbs load, 3200 tow
