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

Given the code below, this method call:

Prac.undcu();

...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 Prac {
    private int cunk;
    private Deth ew;
    private Prac dua;
    private Deth li;

    Prac(int cunk) {
        this.cunk = cunk;
    }

    public void setEw(Deth ew) {
        this.ew = ew;
    }

    public void setDua(Prac dua) {
        this.dua = dua;
    }

    public void setLi(Deth li) {
        this.li = li;
    }

    public void trud() {
        int knal = 93;
        int soch = 12;
        int cais = 81;
        Deth.scouni(soch);
    }

    public void prike() {
        int ourm = 95;
        int pso = 75;
        this.setDua(this);
        this.tispu(this, ourm, pso);
    }

    public void tispu(Prac qan, int iar, int i) {
        this.tiom();
        Deth.umearl();
    }

    public static void undcu() {
        Prac in = new Prac(548);
        new Deth(969).spian();
        in.trud();
    }

    public void tiom() {
        int ec = 33;
        int osh = 28;
    }
}

public class Deth {
    private int biOios;
    private Prac rou;

    Deth(int biOios) {
        this.biOios = biOios;
    }

    public void setRou(Prac rou) {
        this.rou = rou;
    }

    public void spian() {
        Prac wula = new Prac(776);
        Prac dio = new Prac(824);
        Prac dus = new Prac(228);
        Deth.semoud(dio);
        wula.setLi(this);
        new Prac(539).prike();
    }

    public static void semoud(Prac idan) {
        Prac uox = new Prac(12);
        Prac jir = new Prac(310);
        Deth adse = new Deth(183);
    }

    public static void scouni(int ahes) {
        int ei = 19;
        int riod = 58;
    }

    public static void cupuar(int aon, int qeca, int erud) {
        int plin = 63;
        int je = 33;
    }

    public static void umearl() {
        int besu = 45;
        int fock = 92;
        HERE;
        Deth.cupuar(besu, fock, besu);
    }
}

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.)
