Question

This small project is geared to get you started on writing Object Oriented program using either Java or C++.

Create a class called Person that will hold information about a single individual. This class should have a data section that consists of the following:

Variable Name	Data Type
firstName	string
lastName	string
address	string

The Person class should have the following mutators:

• setFirstName(string first);

• setLastName(string last);

• setAddress(string address);

The Person class should have the following accessors:

• string getFirstName();

• string getLastName();

• string getAddress();

The Person class should have the following constructors:

• Person(); - default

• Person(string first, string last); - Set other fields to an empty string

• Person(string first, string last, string address);

Note: You must use delegating constructors to eliminate duplicate code.

Main

Create an array which will hold 5 Person classes. Pass the array to a function called getPeople which will fill out the array with information about people taken from the keyboard. Create a second function called printPeople which will take the array of Person's and print it to the console window. Please format the output so that it can be easily read and understood.

import java.util.Scanner;

class Person {

private String firstName, lastName, address;

public Person() {

firstName = "";

lastName = "";

address = "";

}

public Person(String firstName, String lastName) {

this.firstName = firstName;

this.lastName = lastName;

this.address = "";

}

public Person(String firstName, String lastName, String address) {

this.firstName = firstName;

this.lastName = lastName;

this.address = address;

}

public String getFirstName() {

return firstName;

}

public void setFirstName(String firstName) {

this.firstName = firstName;

}

public String getLastName() {

return lastName;

}

public void setLastName(String lastName) {

this.lastName = lastName;

}

public String getAddress() {

return address;

}

public void setAddress(String address) {

this.address = address;

}

}

public class Main {

public static void getPeople(Person[] persons) {

Scanner sc = new Scanner(System.in);

for (int i = 0; i<persons.length; i ++) {

persons[i] = new Person();

System.out.println("Enter the details for person " + (i + 1) + ": ");

System.out.println("Enter the first Name: ");

persons[i].setFirstName(sc.nextLine());

System.out.println("Enter the last Name: ");

persons[i].setLastName(sc.nextLine());

System.out.println("Enter the address: ");

persons[i].setAddress(sc.nextLine());

}

}

public static void printPeople (Person[] persons) {

System.out.println("The person details are: ");

for (int i = 0; i<persons.length; i ++) {

System.out.println("Details of person " + (i + 1) + " are: ");

System.out.println("First name: " + persons[i].getFirstName());

System.out.println("Last name: " + persons[i].getLastName());

System.out.println("Address: " + persons[i].getAddress());

}

}

public static void main(String[] args) {

Person persons[] = new Person[5];

getPeople(persons);

printPeople(persons);

}
