copy constructor inheritance [closed]

I looked at this link, but didn't really understand what was meant by the clone

Anyways onto my question, so I have a class which inherits two attributes from another class, the class it inherits from has set/get methods and a copy constructor.

I want to implement a copy constructor into the inheriting class (ignore comments in code)

public class Instructor extends Person{
    //officeNumber represents the office number where instructors can be found
    private String officeNumber;

    //constructor allows user to define first and last name and office number in demo
    public Instructor(String fName, String lName, String officeNumber) {
        super(fName, lName);
        this.officeNumber=officeNumber;
    }
}

I want to put the copy constructor here and so far all I can do is this, but I can't just pass in an object into another constructor in a demo class, I have to include the full name

public Instructor(String fName, String lName,Instructor object2) {
    super(fName,lName);
    officeNumber=object2.officeNumber;
}
//get method for field
public String getOfficeNumber() {
    return officeNumber;
}
}

Here is the class it inherits from if that's any help

public class Person {
    //firstName represents the first name of a person
    private String firstName;
    //lastName represents the last name of a person
    private String lastName;

    //constructor allows programmer to define first and last name of object in demo
    public Person(String firstName, String lastName) {
        this.firstName = firstName;
        this.lastName = lastName;
    }

    //copy constructor
    public Person(Person object2) {
        firstName = object2.firstName;
        lastName = object2.lastName;
    }

    //get methods for fields
    public String getFirstName() {
        return firstName;
    }

    public String getLastName() {
        return lastName;
    }
}
