How to sort an Array ArrayList?

Processing Beginners
8

ArrayList<ArrayList<Float>> segs = new ArrayList<ArrayList<Float>>();

In my opinion this is hard to read and to maintain.

Instead make a class MyFLoatClass and an Arraylist of that

Arraylist<MyFLoatClass> list = new ArrayList();

Inside the class MyFLoatClass have another ArrayList.

Much clearer.
