Hello all,

I've been experimenting some stuff on processing and everytime i try to do something with ArrayList class i just cannot figure out how to interact my object with other objects

for example;

thingLocation(Thing t)
{
line(x,y,t.x, t.y);
}

and you call it with arrays like;
t[i].thingLocation(t[j]);

It is okay with Arrays but i just dont know how to interact objects with ArrayList class since it does not use array brackets.

like;

for(int i = things.size() -1; i >0; i++)
{
  p.thingLocation(?);
}

as you see p is just "p" and other object is something i cannot figure out?

i hope my concern was clear,
thanks already
