I have a method that returns a HashMap, and is defined as follows;

public HashMap<Integer, Animal> allAnimal(){

      return returnsAHashMap;
   }

Animal will have the following values in its class:

public Animal{

int animalID;
String animalName;

// i have declared getters/setters
}

I have a GUI screen which has a JList and it's defined as:

l = new JList();
l.setModel(new AbstractListModel() {

        String[] v = new String[] {"animal id 1", "2", "3"};
        public int getSize() {
            return v.length;
        }
        public Object getElementAt(int index) {
            return v[index];
        }
    });

What I want to do is to display the AnimalID's in the JList. I need to find a way to call the allAnimal() method and display all its Animal Id's in the JList. How can i do this ?
