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

Given the code below, this method call:

Aic.cron();

...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 Aic {
    private int emSes;
    private Padot ud;
    private Padot tir;
    private Padot aphe;
    private Aic buke;

    Aic(int emSes) {
        this.emSes = emSes;
    }

    public void setUd(Padot ud) {
        this.ud = ud;
    }

    public void setTir(Padot tir) {
        this.tir = tir;
    }

    public void setAphe(Padot aphe) {
        this.aphe = aphe;
    }

    public void setBuke(Aic buke) {
        this.buke = buke;
    }

    public static void dooro(int frus, Padot ilu, Padot pou) {
        int oim = 69;
        Padot mo = new Padot(961);
    }

    public static void elosh(int feli) {
        int de = 26;
    }

    public void utess() {
        int di = 96;
        int snad = 82;
        int li = 95;
        int shae = 95;
    }

    public void nedirs(Aic ceam) {
    }

    public void ilerd(Padot rios, Padot troc) {
        int nas = 28;
        Aic ardi = new Aic(76);
        Aic.dooro(nas, new Padot(386), rios);
        this.setBuke(this);
        new Aic(684).emeass();
    }

    public void emeass() {
        Padot jiat = new Padot(2);
        int eisu = 23;
        int oris = 97;
        this.nedirs(this);
        jiat.tifir(this, jiat, eisu);
        this.utess();
    }

    public static void cron() {
        new Aic(20).ilerd(new Padot(991), new Padot(758));
    }
}

public class Padot {
    private int crir;

    Padot(int crir) {
        this.crir = crir;
    }

    public void tifir(Aic ba, Padot hul, int al) {
        hul.cesm(this, al);
    }

    public void cesm(Padot vi, int aent) {
        int ie = 19;
        Aic.elosh(ie);
        HERE;
    }
}

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.)
