Java Class Person - Adding Data To Text

Your Tester class main method must use an array or an ArrayList of Person objects. It must be populated from a text data file, friends_data.txt. Add the following data to your text file,

Michelle, 12/20/2008, Camilla
Bryan, 3/8/2007, Tom
Camilla, 6/7/2005, Michelle
Tom, 10/15/2007, Bryan
Charlotte, 3/2/2008, Michelle

Each line has the meaning:

-Person name, Person date of birth (MM/DD/YYYY), name of best friend
-Write a Java program that reads in the data from the friends_data.txt file, allocates a new
-Person for each and then stores the newly created object in either an Array or an ArrayList.
-Next print out a report showing the following information for each Person,

1. The Person's name
2. Their popularity counter
3. Their age on May 1, 2014
4. The name of their best friend
5. The age of their best friend on May 1, 2014

Finally, print the name of the most popular Person and the name of the oldest Person.

Person Class

import java.util.ArrayList;
public class Person {
public String personsName;
public String personsFriend;
public String personsBirthday;
public int personsPopularity;
public int popularity = 0;

[code]...

I keep getting this error from the compiler:

System.out.println("Popularity : " + personsOfInterest[i].getPopularityNumber());

"method getPopularityNumber in class Person cannot be applied to given type:
Required: java.lang.String[]; found: no arguments; reason: actual and formal argument lists differ in length.
