Use Collections java object in Processing.js

Use Collections java object in Processing.js

I'm in need of the Collections object but Processing.js keeps spitting
back an error saying Collections is not defined as though it doesn't
recognize it as an object. I'm trying to find the minimum value of an
ArrayList by using the Collections.min function so this would be really
useful.
ArrayList<int> aaa = new ArrayList<int> ();
println(aaa);
Collections<int> fff = new Collections<int> ();
println(fff);
