How to add items in arrayList?? (newbie) Nov 28th, 2009, 12:04am   Hello; I was wondering how to add items in arrayList. Somthing like this.. class blabla {  ArrayList blabla;  PVector o0 =new  PVector(60,150);  PVector o1 =  new  PVector(120,140);  PVector o2 =  new  PVector(100,50);  PVector o3 = new   PVector(180,200);  PVector o4 = new   PVector(250,150);  PVector o5 = new   PVector(160,250); PVector[] graphics = { o0,o1,o2,o3,o4,o5 }; } Let's say, I have 6 objects in arrayList that hold the position for display some graphic. I want to add some more object to the list. So, I can display more graphic. Something like, when mouseClicked add Pvector(random(width),random(height)) into the list. I'm not sure that my question is clear because I'm new to processing. This is what I'm trying to do. I want to add ellipse in random position When I clicked mouse. Can someone help me??
