arrays - Java classes and ArrayList clarification -

i have created java class , trying larn how arraylist work.

let's have top class called complex. in class have houses, employees etc, of these separate classes.

if wanted create arraylist how go that?

the number of elements dynamic when says add together new house, phone call method asks questions relating house , adds list i'm assuming?

to create arraylist hold objects of type house, can do:

arraylist<house> houselist = new arraylist<house>(); houselist.add(new house());

to loop on items in list

for(house house:houselist){ // house object }

see the documentation larn other functions.
