Trying to get method inside ArrayList of Objects JAVA

Question

I have created an ArrayList of objects and i am trying to call a method inside the ArrayList which would return the value of a string. Using a normal Array i can do this but not sure how to do this using an ArrayList, Below is the code:

import java.util.*;
public class Animal {

    public static void main(String[] args) {
       dog d = new dog("Ralph");
       AnimalList dogie = new AnimalList(d);
       ArrayList dogName = dogie.getAnimalList();


       for(int i=0; i<dogName.size();i++){
           System.out.println(dogName.get(i));
       }
    } 

The class that holds the method is as follows:

public class dog extends Animal{
   String dogName;
    public dog(String dogName)
    {
        this.dogName = dogName;
    }


    public String getName()
    {
        return dogName;
    }
}

I So am trying to using the getName() method to return the string at the index of the for loop, which then I can using in a System.print. I tryed to get .get(i) followed by the method name but it would not work.

Thanks

You don't need to write a new List class. Just specialize ArrayList to hold Animal s.

List<Dog> dogs = new ArrayList<>();

Now, dogs.get(i) returns a Dog . It has a getName method.
