I'm currently doing an array of ArrayList such as the one below
but how can make it into 3D with this arraylist? For example, I'm trying to store have "ANIMAL_KINGDOM" that can store "FISH", "MAMMALS" and "REPTILES" and then in "MAMMALS" I can store the different types of mammals like "MONKEY", "LION" and so on.
ArrayList data2 = new ArrayList;
data2 = new ArrayList();
Any suggestions? Thanks.
