Problem: Overlapping PImages in a simple 2D game

hi guys,
I'm currently working on a simple 2D shooter game. Basically, there's one instance of my player-class and 50 instances of my creep-class on the map. They change position every loop. Something like this:
class Creep {
float x;
float y;
PImage sprite;
...
}
I need to find a way to sort all those instances depending on their Y-position before they are being drawn to the window, so that they're overlapping correctly! e.g. there's creep_a at y=5 and another creep_b at y=6. the game has to draw creep_a first, so that creep_b appears to be in front of it!
My first thought was to create an arrayList for all moving objects (player and creeps), which is then sorted by comparing every Y-position. But no matter how hard I try, I can't find a way to make it work.
I hope you guys understand what my problem is (and excuse my poor english)
Please let me know how you would solve that problem!
thank you,
Al
