Put and Select an object variables in a list

Processing Libraries
1

hello! i need some help to figure it out how can i put a few object variables into a list. What i want is to have a list with the names of the variables, select the variable and with a slider change it value. Here`s my code. I think maybe hashmap its a good option, but i still figure it out how can it works. enligthme

import controlP5.*;

ScrollableList objValues;
ControlP5 cp5;
Obj o;


void setup() {
  size(500, 500);
  cp5 = new ControlP5(this);
  o = new Obj();


  objValues = cp5.addScrollableList("ObjValues", 250, 50, 100, 150);  
  objValues.setType(ScrollableList.LIST);



}


void draw() {
}

class Obj {


  float aa;
  float bb;
  float cc;


  Obj() {
    aa = 10;
    bb = 20;
    cc = 30;

  }
}

your class is not the best source for a list,
add i would start from the latest example cp5.ScrollableList

/**

 *
 * replaces DropdownList and and ListBox. 
 * List can be scrolled by dragging the list or using the scroll-wheel.
