Thread: Array Lists filling for loop

Hi I am having trouble with Array Lists. What should the for loop header be for filling Array Lists?
I am trying to use an explicit value Constant Names in the condition.
Any help would be greatly appreciated. Thank you.
Here is my code.

<       public class PersonTester
{
 
  public static void main(String[] args)
  {
   PersonTester tester = new PersonTester();
   // ArrayList<Person> persons = new ArrayList<Person>(20);
   String ELEMENT = "";
 
    for (int i = 0;i<ELEMENT.length(); i++)
    {
      char gender = tester.getRandomGender();
      String fName = tester.getRandomFirstName(gender);
      String lName = tester.getRandomLastName();
      int age = tester.getRandomAge();
      ArrayList<Person> persons = new ArrayList<Person>(20);
      persons[i] = new Person(fName, lName, gender, age);
      persons.size();
 
      //ArrayList<Person>people = new ArrayList<Person>(fName, lName, gender, age);
      System.out.println(persons);
    }
  }
 
  private char getRandomGender()
  {
    return Math.random() > 0.5? 'f':'m';
  }
 
  private String getRandomFirstName(char gender)
  {
    String firstName = "";
 
    if (gender == 'f')
    {
      firstName = femaleFirstNames[SingleRandom.getInstance().
                                   nextInt(femaleFirstNames.length)];
    }
    else
    {
      firstName = maleFirstNames[SingleRandom.getInstance().
                                 nextInt(maleFirstNames.length)];
    }
    return firstName;
  }
 
  private String getRandomLastName()
  {
    return lastNames[SingleRandom.getInstance().nextInt(lastNames.length)];
  }
 
  private int getRandomAge()
  {
    return SingleRandom.getInstance().nextInt(99) + 1;
  }                                                                                                        >
