Stack frames and objects (like the Idea Lab activity): Correct Solution

Given the code below, this method call:

Scen.lieng();

...will eventually reach the point marked HERE. Draw a diagram of the stack and the heap at that point.

(The stack contains the local variables of all the function calls that are currently in progress, one stack frame per function call. The heap contains all of the objects that currently exist.)

In your diagram:

Label each stack frame with the name of the method.
Label each object with the name of its class.
Include the names of all the variables that belong to each object and stack frame, including the implicit this parameter if present. (You do not need to write the types of any variables.)
When a variable's value is null or a primitive, write the value immediately next to the variable.
When a variable points to an object, draw an arrow from the variable to the object it points to.

The code:

public class Scen {
    private int anAc;
    private Aoil ste;
    private Aoil fasm;

    Scen(int anAc) {
        this.anAc = anAc;
    }

    public void setSte(Aoil ste) {
        this.ste = ste;
    }

    public void setFasm(Aoil fasm) {
        this.fasm = fasm;
    }

    public static void lieng() {
        Aoil pler = new Aoil(169);
        Aoil.tral();
        pler.setIc(pler);
        pler.prer(pler, new Scen(177), 17);
    }

    public void dissci(Aoil pa) {
        int pior = 51;
        int shic = 22;
    }

    public static void ihos() {
        Aoil oas = new Aoil(727);
        Aoil.opast(oas, 65);
        HERE;
    }

    public static void eisPle(Scen au) {
        Scen beos = new Scen(460);
        Aoil er = new Aoil(189);
        Aoil ie = new Aoil(177);
        Scen a = new Scen(105);
    }
}

public class Aoil {
    private int erant;
    private Aoil ic;
    private Scen viar;

    Aoil(int erant) {
        this.erant = erant;
    }

    public void setIc(Aoil ic) {
        this.ic = ic;
    }

    public void setViar(Scen viar) {
        this.viar = viar;
    }

    public static void tral() {
        Scen ta = new Scen(21);
        Scen.eisPle(ta);
    }

    public void prer(Aoil ho, Scen agne, int pei) {
        int caou = 50;
        ho.setViar(agne);
        Aoil.ficse(new Scen(224), pei, agne);
        ho.tianu(ho, pei, this);
    }

    public static void teeght() {
        Aoil qing = new Aoil(35);
        int ec = 9;
        Scen.ihos();
    }

    public static void opast(Aoil clis, int kri) {
    }

    public static void ficse(Scen pruc, int am, Scen us) {
        int iag = 78;
        Aoil ege = new Aoil(362);
        us.setFasm(ege);
        Aoil.teeght();
        us.dissci(ege);
    }

    public void tianu(Aoil spe, int cu, Aoil onur) {
    }
}

Solution

Hints for practicing this puzzle:

Practice with difficulty 0, then work your way up. This will help you get a handle on what the puzzle is asking.
There is only one path through the code from the starting method call to HERE. Start by finding that path.
Be thorough. Double check that you've fully diagrammed each step before you move on to the next one.
You can feed this code into https://pythontutor.com and watch a diagram like this build up step by step. (Yes, despite the web site's name, it also works with Java.)
