Use data from array in an object / creating multiple objects

How do I pass data from an array into an object and how do I create multiple objects?

Is my approach all wrong?
1. //ArrayList people = new ArrayList();
  Person people[] = new Person[0];
2. Human myHuman1;
  Human myHuman2;
  //Human myHuman[i];
3. PFont font;
4. void setup() {
  size (600,600);
  smooth();
  font = loadFont ("ArialMT-24.vlw");
  /* txt file example:
  Smith, John, M, 1910, 1980
  Doe, Jane, F, 1885, 1911
  */
  String lines[] = loadStrings("pendelton.txt");
      for(int i = 0; i < lines.length; i++){
        String values[] = (lines[i].split(","));
        people = (Person[]) append(people, new Person(values[0], values[1], values[2], values[3], values[4]) );
      }
     myHuman1 = new Human(color(0,0,255,10), (1910/10), (1980/10), 70);
     myHuman2 = new Human(color(255,0,0,10), (1885/10), (1911/10), 26);
  /*
  for(int i = 0; i < ??; i++) {
  myHuman[i] = new Human(c, (yearBorn/10), (yearDied/10), age);
  }
  */
  }
  
  void draw() {
  background (255);
  myHuman1.display();
  myHuman2.display();
  /*
  for(int i = 0; i < ??; i++) {
  myHuman[i].display();
  }
  */
  }
5. class Person {
  Person(String nameLast, String nameFirst, String gender, String yearBorn, String yearDied) {
  println(nameLast + " " + nameFirst +" " + gender +" " + yearBorn +" " + yearDied +""+" age " + (int(yearDied) - int(yearBorn)));
  }
  }
  class Human {
  /*
  if (gender == "M") {
  c = (0,0,255,10);
  }
  if (gender == "F") {
  c = (255,0,0,10);
  }
  */
     color c;
     int yearBorn;
     int yearDied;
     int age = (int(yearDied) - int(yearBorn));
6. Human(color tempC, int tempyearBorn, int tempyearDied, int tempage) {
     c = tempC;
     yearBorn = tempyearBorn;
     yearDied = tempyearDied;
     age = tempage;
  }
  void display() {
      stroke(0);
      fill(c);
      ellipseMode(CORNER);
      ellipse(yearBorn,yearDied,age,age);
  }
7. }
